One acre profit of vegetable planting greenhouse

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 basically recover their costs in 1-2 and start to make profits in 3-4 seasons. Assuming that only one mu of land is planted, 5,000 Jin of vegetables can be harvested in the first phase, and the purchase price is 2 yuan per Jin, then the total transaction volume in three quarters of a year is 30,000 yuan, and the annual profit should be around1.8-20,000 yuan excluding costs. Generally, the skeleton of vegetable greenhouse needs about 5500 yuan per mu. In order to save 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 daily use and maintenance. This kind of 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 annual land lease fee is about 800 yuan. Combined with the above calculation, the cost per mu of greenhouse vegetables is about 7000 yuan in the initial stage of planting, and after five years of use, the average annual cost per mu of greenhouse vegetables is about 2500 yuan. The profit of vegetable planting in greenhouse can reach 150%-250%, and it can produce 2-3 seasons of vegetables every year. If ordinary vegetables are planted, the cost of early greenhouse construction and vegetable management can be basically recovered in 1-2 season, so that the first year can be profitable, with an average profit of 100%- 150%. In the next few years, the annual cost is to change some plastic paper. Extended information: greenhouse vegetable planting method 1. Don't apply a lot of undecomposed cake fertilizer to vegetables in greenhouse. 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, which is easy to burn the roots. The cake fertilizer should be broken, soaked in human excrement and urine for about 3 weeks, and then fermented at high temperature before use. Vegetables in greenhouses should not be fertilized under dry conditions. Vegetables are water-loving crops. When the soil is dry, fertilization not only can't give full play to the fertilizer efficiency, but also makes the concentration of soil solution suddenly increase, and vegetables are easy to burn their roots. Therefore, vegetable fertilization should be combined with irrigation, furrowing fertilization, burying fertilizer tightly before irrigation, or topdressing along the water. 3. It is not suitable to apply more phosphate fertilizer and zinc fertilizer in vegetable greenhouse 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. Be careful not to apply iron fertilizer to the soil. Because iron is easily fixed by soil, it is transformed into insoluble compounds and loses its fertilizer efficiency. Iron doesn't flow easily on leaves, so spray it on them. 0. 1%-0.3% ferrous sulfate solution+new high-fat film can be sprayed evenly on vegetable leaves. 5. Don't apply rare earth micro-fertilizer directly into the soil in winter vegetable greenhouse. Spraying 0.05%-0.07% rare earth micro-fertilizer solution+new high-fat film on vegetable leaves is enough.
