It is not good to estimate because the price of construction materials varies from place to place.
In Bozhou, the local construction of a standard greenhouse 8m × 100m fast propagation base, the cost is 80 to 200 yuan per square meter, the reason why the gap is so big, because the selected construction materials are different. The following specific analysis:
Sunshine board price gap is also very large, 40 to 120 yuan per square meter, we generally use 70 yuan / m2 of that kind can be, the price is too low for the greenhouse greenhouse use, too high-grade kind of unnecessary to use. Greenhouse special drip-free film price of about 10 yuan per square meter.
The equipment in the greenhouse special automatic temperature controller can also be used instead of the time switch, semi-automatic control, but to set up a certain number of sensitive thermometers, and on time to see. Ventilation cooling and humidification heating equipment can be used wet curtains and air conditioning equipment, of course, the cost is higher, but the effect is better, you can also use the ventilated windows and heating pipeline equipment, the cost is lower, but the effect is not very good, according to the situation of choice.
Hand drill, soldering iron, welding machine, cutting machine, steel tape measure, protractor, raw material tape and wire 14 #, these devices and equipment are only used in the construction of the base, other times basically do not use it, can be brought by the construction workers, but if you take into account the usual maintenance of the base to facilitate the acquisition can be purchased.
The hardening of the road surface in the base can be used for gardening bricks, which looks beautiful; it can also be used for ordinary bricks, but the surface is rough and needs to be smeared with cement mortar. Cement using ordinary silicate cement will be fine.
High-pressure atomization nozzle can be used ultrasonic atomization nozzle, can also be used agricultural high-pressure sprayer nozzle, generally use agricultural high-pressure sprayer nozzle can be.
Tertiary water supply pipes, tees and elbows can be made of hot-dip galvanized steel pipe, this material is durable, and can be dismantled later, easy to maintain, but at a higher cost; can also be made of PVC, this material is lightweight, easy to install, and at a lower cost, but once the installation of the pipe is completed, it can not be dismantled intact, not easy to maintain.
Other devices and equipment are necessary, can not replace each other.
Based on the above analysis, the cost of building an ordinary 8m×100m standard greenhouse in Bozhou (including equipment cost, material cost and labor cost) is about 60,000 yuan, and the construction period (including the concrete solidification period) is about 4 months.
It seems that the construction cost is a bit higher, but with this mode of fast propagation, the space utilization rate and replanting index can be greatly improved. The yield of one acre of land here is equivalent to 5-6 times of the yield of conventional soil cultivation, which means that the input of this kind of fast-propagation base is only 1/5-1/6 of the input of the conventional soil cultivation base, and it can be said that the input of one acre of land for fast-propagation base is comparable to that of the soil cultivation base of 5-6 acres of land.
In addition, the factory intensive management mode, so that the labor cost input is also greatly reduced, only the conventional soil cultivation of seedlings 1/6 ~ 1/8. conventional soil cultivation of seedlings, the daily management of at least 4 to 6 people per acre of land, and the use of intelligent operation of the fast breeding base, each acre of land only need a person on it.
In addition, the intelligent fast propagation base adopts the zero-discharge management of nutrient solution reciprocal recycling, so the water consumption is only about 1/20 of the same yield of conventional soil cultivation, and the amount of fertilizer is only about 1/3 of that of conventional soil cultivation. Moreover, under the intelligent condition, the plant growth potential is brought into great play, the growth speed is greatly accelerated, and the cycle of fast propagation is greatly shortened. In other words, the output of one mu of intelligent fast propagation base is equivalent to the output of 5-6 mu of conventional soil cultivation base. Moreover, the seedlings produced by the intelligent fast propagation base grow strongly and are net-root seedlings, and there is basically no seedling slowing down period after transplanting. This is not comparable to conventional soil cultivation.
Here is a brief description of aerosol cultivation of vegetables as an example.
Operating 10 acres of aerosol cultivation of vegetable production, at least equivalent to operating 50 acres of conventional soil cultivation of vegetable production, and aerosol cultivation of vegetable quality can reach the green food standard, which is not comparable to conventional soil cultivation of vegetables, the natural price of high, in accordance with the current domestic market conditions, aerosol cultivation of vegetables, the average price of the average price of vegetables is the average price of soil cultivation of vegetables about 3 times. With the average price, at least the price per kilogram can reach more than 10 yuan, with a minimum yield of 20 tons of vegetables per mu (aerosol cultivation of leafy vegetables can reach up to 30 tons per mu), the equivalent value of each acre is 200,000 yuan, 10 acres is 2 million yuan. The annual operation and management cost of each mu of intelligent fast propagation base is about 20,000 yuan, and 10 mu is 200,000 yuan. In this way, after deducting the land acquisition cost, labor cost, running cost and infrastructure cost, 10 mu intelligent fast propagation base running for one year, at most one and a half years will be able to recover the cost, and its efficiency and effectiveness is the fastest return and the most efficient mode in all the cultivation modes at present. Infinite colorful charm, if then it and recreation, sightseeing tours and other organic combination together, will attract more recreation and sightseeing tours to consumers, so that other aspects of the effect and benefits are incalculable. Whether it is the economic benefits, or social benefits and ecological benefits can achieve a higher rate of return than traditional agriculture.
