Apple spray effect is good

The apple squirting spray is to spray micro-sprinkles on the trees every evening during the apple inflating period. According to the experimental research, it is shown that the effect of spraying in the fruit enlargement period is good, and the spray yield is 15.80% per hectare when compared with spraying. The reason for the increase in production of apple spurts is to flush out the dust from the stems and leaves of apple trees after squeezing, which will help increase the light and productivity during the day and maintain the water supply during fruit expansion. In the evening, spraying water can reduce the temperature and control the leaf surface respiration. When the reduction of humidity is less than 60%, daily spraying will be carried out in order to obtain color enhancement and increase fruit's double benefit. The spray volume of 7.50--33 cubic meters per hectare, when the soil moisture needs to be replenished and the evaporation amount is large, it can be taken as a large value, and if it is only required to cool the temperature, a small value can be taken. In the absence of water during fruit enlargement, spray water at 16-17 o'clock every evening. In normal years, from August to August, there is no shortage of water in the soil, and water can be sprayed only after mid-September. When the spray nozzle atomization index to 5000 or more is appropriate to use low pressure bi-directional refraction nozzle, the working pressure of 50 kPa can be.
