At present, it is the greenhouse vegetable production season, and now provide some specific measures on how to improve its economic benefits for the reference of vegetable farmers. Due to the continuous number of continuous cropping vegetables in the garden soil, the virus is more serious. The use of chemical agents for the disinfection of the soil can effectively kill the pathogens that spread the disease and reduce the incidence. It can be sterilized by injecting 3-5 g of carbendazim or 300 g of brominated methanol per square meter of bed soil. Double-layer insulation adopts double-layer insulation measures, that is, a small arch shed is set in the greenhouse. According to the test, the mulch film is added in the shed to raise the ground temperature by 2 °C, and the temperature in the small arch shed in the shed is kept above 15 °C. Instead of using a drip-free film, a polyvinyl chloride-free film is used. With this method, the water vapor in the greenhouse will not condense into water droplets on the shed film, and the vegetable structure in the shed will not be affected by shading. The light transmittance will remain at about 90%, and the photosynthesis of vegetables can be guaranteed. Use plant growth regulators to properly select and use exogenous phytohormones, such as the use of anti-fallin, to promote fruit enlargement, accelerate maturity, and increase yield. Spraying rare earth liquid in the seedling stage of the solanaceous vegetables and spraying the rare earth nitrate solution with the concentration of 0.2%-0.5% at the seedling stage and the initial flowering stage can significantly improve the crop yield and improve the quality. Grafting in the greenhouse for continuous cropping of cucumber, if using black seed pumpkin or Nangu No. 1 is grafted, which can control a variety of diseases and increase production by more than 30%. Strictly prevent ammonia damage According to the determination, the concentration of ammonia in the air exceeds 5ppm, which will lead to necrosis of stems and leaves of vegetables. Therefore, in the cultivation of vegetables in greenhouses, the amount of ammonia fertilizer should be controlled first, and water should be poured in time after using ammonia fertilizer. Apply and cover the soil, pay attention to open the window for ventilation, and strictly prevent ammonia hazards. The reflective curtain is provided with a reflective curtain on the north side of the vegetable greenhouse, which can obviously enhance the illumination on the north side of the vegetable greenhouse and increase the ground temperature by 1.5-3 °C. The method of burning biogas can not only increase the temperature in the shed, but also supplement the carbon dioxide gas for vegetables. After testing various vegetables such as cucumber, green pepper and cauliflower, the yield can be increased by 20%-40%. Drip irrigation adopts under-film drip irrigation technology, the relative humidity of the air in the shed can be reduced by more than 10%, and the mixed disease index is reduced. The use of plant ash in the winter and spring season vegetable greenhouses are closed, the humidity is high, vegetables are prone to disease, and the use of grass ash can effectively prevent the occurrence of various diseases. Evenly applying the ash to the ground can increase the ground temperature and reduce the soil moisture. If the ash is applied to the soil, it can also loosen the soil, increase the fertility, and improve the resistance of the seedling. Improve the multiple cropping index According to the different growth characteristics of different vegetables, select the appropriate variety, arrange the sputum reasonably, and adopt multiple forms of planting, intercropping, and three-dimensional cultivation to improve the multiple cropping index. Look at the market varieties of vegetables cultivated in the next greenhouse, according to market conditions, aim at the market, pick up the gaps, and develop more sophisticated, high-grade vegetables. As long as you grasp the listing season, you can achieve benefits in the time difference.
