The second is to adopt shading and coverage. The shed and the small arch shed can be covered with a shade net to cool down the shade, especially when the summer and autumn vegetables are raised, which can reduce the light intensity and water evaporation. The mountain vegetables can be covered with weeds, straws, etc. in situ, and the thickness is 10-20 cm, which is both moisturizing and cooling. The third is water-saving irrigation. Laying spray (drip) irrigation facilities for drip irrigation can directly transport water to the vicinity of crop roots, which is very suitable for solanaceous fruits and melons. The utilization rate of water is over 90%, which is more than double that of furrow irrigation and flood irrigation. . Sprinkler irrigation is suitable for the production of leafy vegetables such as small green vegetables and Chinese cabbage, and can also be used for vegetable seedlings, saving water and labor and reducing diseases. The fourth is to use a variety of heat resistance. Such as "premature 5", "anti-heat 605" green vegetables, "short leaf 13" radish, cowpea and other varieties.

If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
First, timely and appropriate amount of watering irrigation. To properly arrange the irrigation time, water should be poured in the morning, evening or night to avoid watering in the afternoon high temperature and improve the utilization efficiency of soil water in the field. When watering, you can use hole pouring, furrow irrigation or drip irrigation, and do not flood the water.
