How to manage greenhouses with higher profits?

1. According to market demand, select high-quality varieties

The production of off-season vegetables should be based on local consumption habits, combined with the performance of the greenhouse. Affected by the environmental temperature, the coldest season greenhouses should be planted mainly with leafy vegetables, and at the same time, the influence of the influx of out-of-town vegetables into the local area should be considered. If a large-scale production pattern is formed, more attention should be paid to the selection of varieties, and varieties with strong resistance, good quality and high yield should be selected according to local conditions.

2. Thermal insulation and lighting performance of greenhouse

There are no heating facilities in the greenhouse. The energy source of the greenhouse is mainly light, so special attention should be paid to the issue of heat preservation. The insulation material of the greenhouse should be made of quilts and other materials that are impermeable and have good thermal insulation properties. The lift and cover of the quilt are also To master the time, raise the quilt every morning when the sun rises and there is sufficient light, and cover the quilt when the sunlight is weakened in the afternoon when the greenhouse cannot fully absorb heat. The greenhouse film is not suitable for long-term use. In order to avoid affecting the daylighting, use the greenhouse film _Clean up the snow and debris in time, and always keep the greenhouse film with the best light transmittance. In addition, if the greenhouse film is found to be damaged, it should be repaired or replaced in time.

3. Reasonable arrangement

Vegetables of the same species and the same family should not be planted continuously, otherwise it will easily lead to pests and diseases and low yield. It is best to choose the stubble between different families in the arrangement of the stubble in the greenhouse. In addition, the arrangement of the stubble should be based on the season, environment and temperature. Restrictions and requirements are determined. Import arrangements directly affect production and benefits, so sufficient attention should be paid.

4. Strengthen scientific management and increase scientific and technological efforts

Since greenhouses are the main vegetable production equipment in the off-season, they are greatly affected by natural conditions and the environment, so producers and technicians are required to

Possess definite scientific knowledge and planting experience, intensive cultivation, strengthen water and fertilizer management and pest control.

In winter and spring, the temperature is relatively low, and the requirements for fertilizers are relatively strict. High-quality decomposed organic fertilizers should be applied, and chemical fertilizers should be used as little as possible to improve the physical and chemical properties of the soil and improve the fertility of the soil. Multiple harvests are carried out in the greenhouse, the replacement time is short, and the next seedlings need to be cultivated in advance.

The phenomenon of idle fields, in addition, the nursery room and the production room should be separated as much as possible.

5. Change concepts and update ideas

In the new type of greenhouse, in addition to the normal planting of vegetables, flowers, fruit trees, edible fungi, special vegetables, etc. can also be planted accordingly. According to the local climate, environment and people's consumption level, consumption habits, and consumption concepts, the types of crops can be appropriately changed to improve Economic benefits, while providing more cropping arrangements for vegetable production.

6. Apply new technology

Under suitable conditions, the application of new technology greenhouses can use reflective screens, CO2 gas fertilization, grafting and removing roots, multi-layer coverage, drip irrigation, smoke, dust agent application and other high-tech to enhance the benefits of greenhouses.
