First, closely focus on green and safe vegetable production and implement the green promotion plan.
The street is the main first-line vegetable base in the city, which bears 70% of the vegetable supply in the urban area. In order to ensure the safe supply of green vegetables in urban areas, on the basis of the popularization of pollution-free vegetable production technology, the project of "municipal green vegetable project construction" was implemented from 1999. After three years' efforts, a "one model, three systems" green and safe vegetable production industrial system was established. A number of first-line vegetable bases operated by farms such as Hua Teng Agricultural Service Company, Li Qiang Block, Shangfujia Road Block, Shiqiaotou Block and Xiyangsi Block have been established. Through experimental research, the technical system of insect-proof net, frequency vibrating insect-killing lamp, sex pheromone, yellow board sticking, increasing application of organic fertilizer and safe use of high efficiency, low toxicity and low residue pesticides was established. Innovating the covering form of insect net, frequency vibrating insect-killing lamp+insect-trapping bag and plant source trapping technology has expanded the harmless prevention and control means of pests and diseases in green vegetable production and the forecast of pests and diseases, which has played a positive role in vegetable plant protection in the city. The water quality, soil, atmosphere and agricultural product quality of 10,000 mu of land were comprehensively tested and evaluated, and the problem of pesticide residues in vegetables was dynamically and systematically detected. Through comprehensive determination, the water quality, soil and atmospheric conditions of the ten thousand mu plot meet the national green vegetable production standards, and the quality of the produced agricultural products meets the national green agricultural product quality requirements. In 20XX, it was recognized as one of the five pollution-free vegetable production towns in Ningbo by the Food Office, and in 20XX, it was recognized as one of the five pollution-free vegetable production towns in Ningbo. On the basis of standardized management of base construction, counters for assured vegetables have been set up in three major farmers' markets in urban areas since 2XXX, and 70 brands of assured vegetables are distributed every year, and the market is responsible for sampling inspection and safety control of assured vegetables. In the past three years, vegetable food poisoning accidents have occurred at the end of urban areas. At the same time, we actively explore new areas of urban vegetable marketing. In the second half of 20XX, we set up an urban vegetable distribution center, which has been distributed to government canteens and four schools. The daily delivery volume has reached1xx0kg, and it is planned to expand to community clean vegetable delivery in the first half of next year. Through the implementation of the "Urban Green Vegetable Project", it not only ensures the supply of green and safe vegetables in urban areas, but also effectively promotes the income of vegetable farmers. During the implementation of the project, * * * increased its income by16.325 million yuan, and the annual income of insect nets alone increased by1428,000 yuan, with an average yield increase of 1260 yuan per mu, with an annual increase rate of. At the same time, through the implementation of the project, the basic operating procedures and working methods of green agricultural products production have been mastered, which has laid a solid foundation for the overall green promotion plan of the street. For example, "Hunong" brand high-quality grapes have passed the examination and approval of China Green Certificate Center. In the future, more varieties will be recognized as green agricultural products, and the brand of "Shanghai Nong" green agricultural products will be launched.
Two, relying on the development of seeds and seedlings, expand the scope of technical services.
Streets are cities and towns. With the needs of urban construction, the land area is decreasing year by year, and it is also the place where agricultural technicians gather. How to give full play to the advantages of agricultural technology and improve the role of agriculture in the overall promotion of agricultural industrialization in the city? On the basis of grasping the layout of suburban industrialization of existing cultivated land, we should focus on the introduction, digestion, absorption and innovation of seedling technology, and popularize advanced and practical technology through seedling radiation. It has successively undertaken seedling development projects such as pepper hybrid seed production, seedling breeding and promotion of main greenhouse vegetable varieties, research on factory seedling raising technology, introduction of French tomato No.6 and construction of asexual propagation system, which not only formed a regional seedling breeding base, but also quickly spread the propagated seedlings to surrounding towns, counties and cities with its variety and quality advantages. For example, the topic of "hybrid seed production of vegetable pepper" has opened up the field of hybrid seed production of vegetable pepper in Ningbo. Compared with the middle pepper series, the yield of yellow-shelled lamp pepper increased by 18.7%, with an average yield of 38XX kg per mu. At the same time, the shell of yellow-shelled bell pepper is yellow-green, with good color, large shape, uniform corners and good waxy property, which is suitable for dehydration processing. The annual seed breeding is 30 kilograms, and the promotion area is 2 xx mu. It's on the street. Deqing Seed and Seedling Co., Ltd. was established by the research group of "Breeding and Promotion of Seed and Seedling of Main Vegetable Varieties in Greenhouse", which is one of the leading seed and seedling enterprises in the city. After three years' construction, the company covers an area of 90 mu, with fixed assets of 6,543.8+500,000 yuan, 8× x0 square meters multi-span greenhouse and 825-type pipe shed production base of 1XX, and has established a technical system of variety comparison, hybrid seed production, routine purification and rejuvenation, and annual seedling raising. 8788 red tomato, 988 pink tomato, 20XX pepper and other high-yield and high-quality varieties have been screened out, which have been promoted in certain areas in production, with a cumulative promotion area of more than 2x0mu; Yellow-shelled capsicum, Shanghai hybrids 70, 90, 120 days and 8788 tomato hybrids with an annual output of 50 kg were formed. Conventional fine varieties (such as Ningbo rattan eggplant, Yang Jiao pepper 804, Ningbo green belt) are purified, rejuvenated and bred for 2×kg；; Seedling production is carried out in winter and spring every year, with 35 varieties and 15XX million seedlings per year. The bred seedlings have established a good reputation among growers because of their variety and quality advantages. Relying on science and technology demonstration households and agricultural technicians from all over the country, it quickly spread to surrounding counties and cities and outside the province, with an annual promotion area of 6.5438+0 million mu, increasing farmers' income by 4.8 million yuan.
Based on the successful experience of seed and seedling construction in previous years, in order to comprehensively improve the industrialization level of seed and seedling, the "research on factory seedling technology" and "construction of clonal propagation system of French tomato No.6" have been implemented since 20XX, and a semi-factory seedling technology system with plug, peat substrate, electric seedling in winter, shading and cooling in summer and autumn has been formed, and grafted watermelon seedlings 1XX plants and broccoli seedlings have been formed every year. In the first half of this year, 654.38+million grafted watermelon seedlings were cultivated, with an application area of more than 3× mu, which basically solved the obstacle of continuous cropping of watermelon in greenhouse and the occurrence of watermelon wilt, and the yield of grafted watermelon seedlings was more than 20% higher than that of conventional watermelon seedlings. In the second half of this year, 50,000 grafted watermelon seedlings were cultivated in summer and autumn, with a cultivation area of 1XX mu. The experiment in each experimental site (30 mu) has achieved remarkable results, with an average output value of more than 3× 0 yuan per mu, which has created a new situation of local watermelon anti-season cultivation. In cooperation with Haitong Group, a pilot project of unified seedling supply of green cauliflower was carried out, and 6,543,800 plug seedlings were cultivated through * *, with 9 planting sites and a planting area of more than 50 mu, which was well reflected in various places, and the speed of slow seedling emergence was higher than that of autotrophic bed soil. In view of the characteristics of strong growth potential, good disease resistance, high yield and excellent quality, the introduction of foreign tomato varieties has been intensified. Through variety comparison, French tomato No.6 has good comprehensive characters, which is suitable for anti-season cultivation in early spring and summer and autumn in this area. It should be popularized in production to realize tomato variety renewal. However, due to the high price of imported tomato seeds, ordinary farmers can't afford it (the cost of seeds per mu is about 12XX yuan). On the premise of establishing scion nursery, we established the asexual propagation system of French tomato No.6, and have cultivated more than 20,000 asexual seedlings. We tried planting in the center base of side dishes, and observed that there was no difference in fertility characteristics between asexual seedlings and seed seedlings, but the growth rate of seedlings was greatly accelerated. Generally, it can be planted about 1 month, which can shorten the time by about half compared with seed propagation and greatly reduce the production cost of growers (the cost of seedlings per mu is about 6XX yuan). It is planned to breed 500,000 plants next year, which is expected to be widely promoted in production.
Three, vigorously develop facilities cultivation technology, promote the healthy development of leading industries.
Greenhouse facility cultivation is the development direction of suburban agriculture in our city, and it is also the highlight of agricultural science and technology innovation. To a great extent, the progress and perfection of vegetable production technology is an extension of facility cultivation technology, such as the application of pollution-free and green vegetable production technology and sprinkler irrigation and drip irrigation technology in vegetable production. Therefore, vigorously studying the supporting technology of facility cultivation can not only promote the healthy development of leading industries in suburbs, but also effectively promote the technical reserve of urban agricultural industries. We have carried out a series of technical development around protected cultivation, including the introduction and characteristics observation of French tomato No.6, the introduction and protected cultivation of Eurasian grapes, the cooperation with the municipal agricultural machinery company to design and promote water-saving irrigation systems, greenhouse vegetable seedlings and harmless control technologies, which greatly promoted the healthy development of suburban agriculture. The greenhouse facility cultivation area is increasing year by year. By 20XX, the whole street facility cultivation area will reach 35XX mu. It accounts for about 25% of the city's protected cultivation area, realizes the diversification of greenhouse protected cultivation, and creates the annual harvest and autumn production of greenhouse watermelon. A spray drip irrigation exhibition area was set up separately in the park, and various types of spray drip irrigation were studied and displayed. The shed group, single shed and field irrigation and drip irrigation systems are designed, which opens up the application fields of suspended micro-sprinkler and landscape sprinkler. In recent years, the shed group spray and drip irrigation system has developed the fastest, with a construction area of 5XX mu. Greenhouse spray and drip irrigation system has the functions of saving labor and water, realizing integrated management of fertilizer and water, reducing secondary salinization and increasing greenhouse output, which has been accepted by the vast number of agricultural demonstration parks and scientific and technological demonstration households.
Four, the construction of regional agricultural technology innovation center, enhance the vitality of scientific and technological innovation.
In order to meet the needs of the development of agricultural science and technology under the new situation, streets should keep pace with the times, give play to the advantages of strong agricultural science and technology in urban areas, and explore the role of streets in the progress of agricultural science and technology in the whole city. With the strong support of Science and Technology Bureau, we undertook the construction of "Agricultural High-tech Research Demonstration Base", aiming at establishing a regional and open agricultural science and technology innovation center in the implementation of agricultural modernization project in Ningbo, and absorbing agricultural science and technology forces inside and outside the city. After two years' construction, the regional agricultural innovation base has begun to take shape, with the Hunong Horticultural Research Institute and Deqing Vegetable Technology Research Institute as the core, with a high-grade greenhouse of 15280 square meters, equipped with internal and external shading, fan wet curtain atomization spray cooling system, heater heating system, spray drip irrigation system and temperature and humidity environment detection system. There are 7,430 multi-span greenhouses with an area of 8XX0 square meters, 825 single-pipe sheds 1XX mu, supporting spray and drip irrigation systems and agricultural production demonstration facilities, complete roads and canals, and a rapid detection laboratory for pesticide residues. Tissue culture laboratories and cultivation laboratories will be built, forming a relatively perfect basic condition for agricultural innovation. At present, it has basically undertaken all agricultural science and technology innovation projects, and actively absorbed scientific research forces from inside and outside the city to participate in agricultural science and technology innovation. Established a good cooperative relationship with Zhejiang University Agricultural College and Ningbo Agricultural Institute, and cooperated with Agriculture and Forestry Institute to develop fresh dates. The technology extension department of the Municipal Agriculture Bureau went deep into the park in the form of a research group to participate in agricultural science and technology innovation. For example, they cooperated with the agricultural technology extension center to develop grafted watermelon seedlings, and the municipal testing center participated in the construction of green vegetable projects. With the further improvement of the facilities of agricultural technology innovation center and the establishment of agricultural technology innovation system in the form of subject, the opening and benefit sharing mechanism of the park will greatly improve the vitality of scientific and technological innovation and become one of the agricultural technology innovation centers in the city.
Five, do a good job in practical technical training, improve the rate of technology in place.
On the premise of grasping the innovation of agricultural science and technology, streets should strengthen the combination of agricultural science and education, speed up the popularization of practical technology, and truly transform agricultural science and technology into productive forces. Through lectures, on-site meetings, targeted counseling for farmers who come to the park for consultation, and direct guidance on field visits, we will do a good job in practical technical training and promotion. Streets and villages hold no less than 30 practical agricultural technology training courses in different farming seasons every year, and the number of participants is 12XX. In the training, the application of green vegetable production technology is emphasized. In greenhouse cultivation, the application of fine varieties, insect nets, increased application of organic fertilizer and safe use of drugs have basically become the conscious actions of the majority of growers. At the same time, make full use of the project funds, carry out the basic transformation of farmland in an all-round way, and complete the construction of standard farmland13xx00 mu, which greatly improves the flood control and drought relief, transportation and farming conditions, and provides a guarantee for the application of advanced and practical technologies. It is the town with the largest application area of multi-span greenhouses, 825 pipe sheds, spray and drip irrigation and greenhouse agricultural machinery in the city, and has trained a number of towns and villages such as Chen Zhidong, Sun Guojun and Huang Guozhen.
