The role of water in the production of summer vegetables The first is to promote the growth of plant roots to meet the plant's need for water. Soil watering on the one hand will add moisture to the growth of vegetables, and at the same time it will change the ratio of gas to liquid in the soil and affect the growth of vegetable roots. Rational soil moisture management can promote root growth and cultivate healthy vegetable roots. The second is to reduce the temperature in the shed. Since we use groundwater with a relatively constant temperature (around 17°C for a year), water can be used as an important measure for reducing the temperature of vegetables in summer, depending on the characteristics of the large specific heat of water. The third is to increase the air humidity. Increasing air humidity in high temperature environment can effectively increase the resistance of vegetables to high temperature environment. Summer water management method First, a reasonable watering. Watering vegetables in summer greenhouses on the one hand is to supplement vegetables with water, but also assumes the role of cooling greenhouses, so pay attention to the combination of water and small water. Especially for young plants that have just been planted, it is particularly important. Drenched water promotes hair roots, and small water wetlands cool down. Second, irrigation canals, roof spraying. In high temperature weather, the water canal is sprayed at 9:00 am or installed at the top of the roof. Spray water is sprayed at 9:00 am and 4:00 pm every day. These measures reduce the temperature in the shed and increase the shed height. Humidity improves the resistance of vegetables to high temperatures and reduces the occurrence of high temperature damage and viral diseases.

Over summer vegetables summer moisture management
Water is one of the most important factors in the production of vegetables. Rational use of water is an important part of vegetable production. For the vegetable production in the protected areas in over-summer, the rational management of water is also an important measure to promote the production of vegetables. In this paper, we will address the issue as follows:
