According to the market situation, the profit of greenhouse vegetable cultivation is about 150%. That is to say, in the vegetable planting in 3-4 seasons of a year, farmers or investors have basically recovered their costs in 1-2 period, and have already started to make profits in 3-4 period.

Assuming that only one acre of land is planted, 5,000 kilograms of vegetables can be harvested in the first phase, and the purchase price per kilogram is 2 yuan, then the total transaction volume is 30,000 yuan per year according to the calculation of three seasons. Excluding the cost, the annual profit should be about1.8-20,000.

Generally, the skeleton of vegetable greenhouse needs about 5,500 yuan per mu. In order to save the cost and prolong the service time of greenhouse, the more economical way to build greenhouse is to use magnesite greenhouse skeleton and plastic paper, which not only reduces the construction cost, but also facilitates the daily use and maintenance. Such a greenhouse can be used for 5 years, and only plastic paper needs to be replaced every year. The annual cost of vegetable seedlings, pesticides and fertilizers per mu is about 700 yuan, and the land rental fee is about 800 yuan every year.

Combined with the above calculation, the cost of vegetable planting in greenhouse is about 7,000 yuan per mu, and the average annual cost of vegetable greenhouse is about 2,500 yuan per mu based on the five-year use period.

The profit of greenhouse vegetable planting can reach 150%-250%, and vegetables can be produced for 2-3 seasons every year. If ordinary vegetables are planted, the vegetables in 1-2 season can basically recover the initial construction and greenhouse vegetable management costs, so that the first year can be profitable, with an average profit of100%-/kloc.

Greenhouse vegetable planting method

1, don't apply a lot of cake fertilizer that is not decomposed in greenhouse vegetables. Because the ratio of carbon to nitrogen of cake fertilizer is small and it decomposes quickly, it is easy to produce high temperature and high concentration of ammonia and organic acid locally, and it is easy to burn roots. The cake fertilizer should be broken, soaked in human feces and urine for about 3 weeks, and then used after high-temperature fermentation.

2. Vegetables in greenhouses should not be fertilized under dry conditions. Vegetables are water-loving crops. When the soil is dry, fertilization will not only bring the fertilizer efficiency into full play, but also make the concentration of soil solution suddenly increase, which will easily burn the roots of vegetables. Therefore, vegetable fertilization should be combined with irrigation, furrow fertilization should be carried out, and the fertilizer should be buried tightly before irrigation, or topdressing should be carried out along the water.

3. It is not suitable to apply more phosphate fertilizer and zinc fertilizer in vegetable greenhouses in winter. When vegetables are deficient in zinc, 0.05%-0.2% zinc sulfate solution and new high-fat film can be sprayed on the leaves.

4. Be careful not to apply iron fertilizer to the soil. Because iron is easily fixed by soil and converted into insoluble compounds, it loses its fertilizer efficiency. Iron is not easy to flow on leaves, so foliar spraying should be adopted, and 0. 1%-0.3% ferrous sulfate solution and new high-fat film can be evenly sprayed on vegetable leaves.

5. Don't apply rare earth micro-fertilizer directly into the soil in the vegetable greenhouse in winter. 0.05%-0.07% rare earth micro-fertilizer solution and new high-fat film can be sprayed on vegetable leaves.
