How to improve the economic benefits of greenhouses

With the development of modern agriculture, the greenhouse greenhouses are more and more widely used in agricultural production, but a large part of these greenhouses are not used properly, and the economic benefits are not obvious or have no benefit at all. The key to improving the economic benefits of greenhouses is to reduce costs and adopt comprehensive measures to improve utilization.

First, choose the type of greenhouses as needed. At present, the promotion is more common is the linkage of greenhouses and plastic greenhouses. The former has a high cost. If it is heated in winter, the operating cost is also high. The latter is relatively low in cost, but the strength of the steel pipe is not large, the space in the greenhouse is small, and the construction operation is relatively inconvenient. We can choose according to our own planting conditions, or combine the two characteristics to make it have the function of interlocking greenhouse, beautiful and generous, and durable.

Second, plant high-yield crops. Greenhouse greenhouse cultivation is relatively expensive for open-air cultivation, and crops that can be planted all year round and have low benefits are not planted in greenhouses. From the experience of using greenhouses everywhere, the best benefit is seedling breeding. For example, some township agricultural technology stations invest 20,000-30,000 yuan to build greenhouses to grow vegetables and fruit trees, which not only promotes excellent varieties, but also obtains considerable income. In addition, the production of off-season vegetables can also produce better benefits.

Third, the use of comprehensive supporting technology to increase the use of greenhouses. Common supporting technologies for greenhouses are:

1 spray drip irrigation technology. Compared with conventional production, the production of sprayed drip irrigation in greenhouses can increase production by about 20% and economic benefits by more than 30%.

2 shade cooling cultivation. In the high temperature season, greenhouse greenhouses cover the shade net to reduce temperature and increase production and quality. If the micro-spray cooling is used at the same time, the influence of high temperature weather can be overcome, so that the greenhouse can also play a role in the summer.

3 Use insect nets. The use of insect-proof nets is low in cost and the effect is very satisfactory. Generally, the output is increased by more than 10%, and the economic benefit is increased by more than 20%. Especially for fast-growing leafy vegetables, the use of insect-proof nets can greatly reduce the application of pesticides, reduce the pesticide residues of vegetables, reduce costs, and increase vegetable prices and economic benefits.

4 Early-season close-planting cultivation techniques in greenhouses. The greenhouse uses this technology to cultivate pumpkin, cucumber, loofah, etc., and the output value can be increased by 20%.

5 play the role of the greenhouse greenhouse. The use of greenhouse greenhouses for bitter gourd, cucumber, loofah, beans, etc. can not only save the cost of the stent, but also increase the yield.
