Rural greenhouse planting! What is the most profitable way to grow?

With the increase in the number of greenhouses, how to make vegetables grown in greenhouses bring higher economic value has become a difficult problem facing vegetable farmers. The following experiences can be used for your reference.

Since most greenhouses have no heating facilities, the energy source of greenhouses is mainly light, so we should pay special attention to the problem of keeping warm.

Greenhouse insulation materials should be selected, such as quilts, and good insulation performance. The lifting and covering of the quilt should also master the time. Every morning, when the sun rises and the light is sufficient, the quilt should be lifted. In the afternoon, when the light decreases, the greenhouse can not fully absorb the heat, the quilt will be covered. Greenhouse film should not be used for a long time, in order to avoid affecting daylighting, when there is snow and debris dust on the greenhouse film should be cleaned in time, always keep the greenhouse film has the best light transmittance, in addition, if found that the greenhouse film damage should be repaired or replaced in time.

2, according to the market demand, choose high-quality varieties

Off-season vegetable production should be based on local consumption habits, combined with the performance of the greenhouse. Due to the influence of environmental temperature, the greenhouses should mainly plant leafy vegetables in the coldest season, and consider the influence of the influx of non-local vegetables on local vegetables. If a large-scale production pattern is formed, more attention should be paid to the selection of varieties, according to local conditions to select varieties with strong resistance, good quality and high yield.

3. Strengthen scientific management and strengthen science and technology

Because greenhouses are the main vegetable production equipment in the off-season, affected by natural conditions and environment, producers and technical personnel should have certain scientific knowledge and planting experience, intensive cultivation, strengthen water and fertilizer management and disease and pest control.

Winter and spring season temperature is low, the requirement of fertilizer is more strict, should apply high-quality organic fertilizer, as little as possible or do not use chemical fertilizer, in order to improve the physical and chemical properties of the soil, fertility. In the greenhouse for a variety of harvest, stubble change time is short, need to cultivate the next crop in advance, do not allow idle field phenomenon, in addition to the seedling room and production room as far as possible separate, due to the difference of environmental requirements, not convenient management at the same time, can avoid mutual infection of pests and diseases.

4. Arrange stubble reasonably

The same kind of vegetables should not be continuous cropping, otherwise easy to cause diseases and pests and low yield. Greenhouse vegetable planting in stubble arrangement is the best choice between different branches of stubble, conducive to growth. In addition, the stubble arrangement should be decided according to the restrictions and requirements of season, environment and temperature. Stubble arrangement directly affects the output and benefit, so it should be paid enough attention to.

5. Apply new technology

Under appropriate conditions, the application of new technology greenhouse can use reflective curtain, grafting root removal, multi-layer covering, drip irrigation, smoke, dust agent application and other high-tech to improve the benefit of greenhouse.

6. Change ideas and update ideas

In the new greenhouse, in addition to the normal planting of vegetables, flowers, fruit trees, edible fungi, specialty dishes, etc., can be appropriately changed according to the local climate, environment and people's consumption level, consumption habits, consumption concepts, can improve economic benefits, and provide more stubble arrangements for vegetable production.

Under the premise of ensuring the cost of greenhouse, appropriate use of the above methods, will be able to maximize the benefit of greenhouse in a short time.
