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.
