2. The choice of nursery is very important. First of all, we should choose an area with convenient transportation, preferably close to the core city or between several cities, and close to the main road. The road in and out of the nursery must be good, and it can withstand trucks loaded with big trees, which is conducive to the transportation and sales of seedlings. Secondly, it is best to be close to rivers or large reservoirs. Adequate water is the key to the growth of seedlings, especially in nurseries with potted seedlings. In addition, if the nursery mainly grows ground seedlings, the soil quality, soil fertility and pH of the nursery should also be considered. Generally speaking, deep, loose, fertile medium sandy loam with high organic matter content is suitable for planting various garden plants. Compared with sticky and barren soil, sandy loam may have higher land price or rent, but because of its fast growth, good quality and quick emergence from the nursery, it can gain early and get higher profits. 3. The scale of the nursery The scale of the nursery built is first determined by the investment. The type of nursery also depends on the size of the nursery. For example, the production nursery, which is mainly retail, needs less land. In North America, 2-4 hectares is generally enough, while non-retail production nurseries need more land, ranging from dozens to hundreds of hectares. In the early stage of nursery preparation, there are two ways to choose the nursery scale. One is that the nursery scale is in place at one time, that is, renting dozens to hundreds of hectares at a time, planting a part at first, and expanding it continuously before selling until the whole nursery is planted. This method is suitable for investors with sufficient funds; The other is to rent a small piece of land first, and then rent it when the land is full or when the seedlings grow up and need to move, so as to expand the seedling area. This can save money and is suitable for investors with less funds, but the later development may be restricted by similar land when needed. The above two methods have their own advantages and disadvantages. Therefore, the scale of nursery should be determined according to the investment and development preference of nursery. 4. Types of nurseries In North America, there are two main types of nurseries: one is classified according to the planting methods of seedlings, which are mainly divided into field planting nurseries and container planting nurseries, and field planting nurseries also include the production of some small container seedlings and root seedlings. The seedlings in container nursery are mainly planted in plastic containers. The advantage of container cultivation is that the planted seedlings grow evenly and can be used for landscaping all year round, which does not affect the growth of trees and avoids the influence of field cultivation on the growth of seedlings and the damage to trees. Therefore, the price of container green seedlings is relatively high; Its disadvantage is that it mainly depends on artificial watering, and the root growth is restricted by containers. With the growth of seedlings, replacing large containers increases labor costs, and winter needs cold protection. The other is classified according to the function of nursery, which is generally divided into retail nursery and non-retail nursery. The former directly sells products to users, while the latter retails a large number of products to garden projects or large garden cores. In China, there is no clear classification of nurseries, and the type of nurseries to be built can be determined by the investment and controlled market. In the future urban development, greening is needed all year round, and the required trees are required to maintain a perfect tree shape. Container cultivation can meet this development demand. It can be said that container cultivation will be one of the main development trends of nurseries in China, which is more in line with the needs of landscaping and urban construction. 5. Selection of Garden Plants For the new nursery, the old nursery has no burden of old tree species and old varieties, so it is very important to choose the green species to be planted. (1) should be distinctive. For example, in the United States, a variety of conifers and beautiful trees make it unique in the nursery industry in North America; Canadian plants are well-known in nursery circles in North China because of their management of American plants. Japan Garden is famous for its Guohua series chrysanthemums. There are hundreds of kinds of Guohua series chrysanthemums imported from China, which may be familiar to ordinary flower lovers. South Korea's Merrill Lynch Botanical Garden mainly deals in maple trees and rises rapidly. There are also many such examples in China, such as the lotus pond in Nanjing, which developed rapidly from collecting and managing aquatic plants such as water lilies and lotus flowers, and its products are exported to Europe, America and Japan. (2) Specialized and large-scale production. With the continuous development of nursery industry, the competition is becoming more and more fierce, and the production mode of nursery will definitely move towards specialization and large-scale folk exhibition, with regional specialized production such as Heze Peony, Nanjing Tangquan Cedar, Zhejiang Jinhua and so on. When investing in nurseries, it is necessary to determine the bias of nurseries and develop towards specialization, with a few types as the main ones. Don't be "small and complete", otherwise it will be difficult to form a scale and enter the market quickly. (3) When choosing plant varieties, we should be predictable, that is to say, planting those varieties that can adapt to future development. Generally speaking, we should give priority to the excellent green ornamental plants in China, supplemented by the introduction of new excellent varieties from other places. In this respect, some horticultural enterprises have taken the lead, such as Zhejiang Yue Hong Flower Co., Ltd., Shanghai Botanical Garden, Jiangsu Future Agriculture and Forestry World, etc. Many excellent foreign varieties have been introduced and propagated rapidly. At the same time, we should pay great attention to the living habits and ecological adaptability of introduced varieties to prevent unnecessary losses. There are many such examples in the nursery industry in China, which is a waste of money and time. In addition, it is particularly important to have a group of high-quality management technicians; 2 1 century is the era of knowledge economy. With the development of modern economy, it is increasingly dependent on science and technology and high-level governance. It is extremely difficult to build a nursery. It is very difficult to build a good nursery. It's just that the nursery is large in scale and there are many varieties of seedlings. Unexpectedly, it is a good nursery. The key depends on the management of nursery and the quality of seedlings. If the seedlings in the nursery have beautiful tree shape, consistent planning and bright colors, the competitiveness of the nursery will be strong and will continue to develop, which requires high-quality management and technical personnel.
