Attention should be paid to irrigation of fruit trees in greenhouse

First, the quality of water.

Surface runoff water often contains a lot of organic matter and minerals; Rain Water contains more carbon dioxide, ammonia and nitrate nitrogen; snow water contains more nitrate nitrogen. These ingredients are beneficial to the growth of fruit trees. In sprinkler irrigation and drip irrigation, special attention should be paid to the irrigation water should not contain sediment and algae, so as not to block sprinklers or emitters.

Second, regulate the water temperature.

River water and groundwater, the temperature is generally low, can be stored in the reservoir, after a period of time to increase the temperature and aeration reuse. The irrigation time of the day, especially in the greenhouse, is generally chosen before 10:00 in the morning, when the water temperature is close to the soil temperature, which can reduce the adverse effects of sudden cooling on the roots of fruit trees due to irrigation.
