Apple's expansion encounters drought?
The fruit expansion period of apple is positive in summer, with high temperature and large evaporation. Only suitable moisture can promote fruit enlargement. In case of drought, the lack of soil moisture will affect the development of the fruit, resulting in a smaller fruit, reduced yield, and decreased quality. However, if there is too much water in the soil, it will cause long autumn shoots and loss of nutrients. If the accumulation of water takes a long time, it will affect the respiration of the root system, premature aging of the tree, and loss of the lower leaves. Therefore, in this period, we must master the water balance, control the excessive fluctuation of soil moisture, promote the normal development of fruits, and ensure high yield and quality. 1, drought irrigation In case of drought in this period, it should be timely irrigated, replenish water, promote fruit enlargement, and increase production. The key technology of irrigation during this period is to grasp a reasonable amount of irrigation, and to control the amount of irrigation according to the soil texture and drought degree, it should not be too large, so as to avoid causing cracking and lower quality. 2, water-saving irrigation The purpose of water-saving irrigation is to strictly control the amount of irrigation. In conditional orchards, water-saving irrigation shall be implemented by means of sprinkler irrigation, drip irrigation and infiltration. Water-saving irrigation has the characteristics of water saving and high water utilization. After the implementation of water-saving irrigation, not only can it protect the soil structure, but also make the root system in a relatively stable humidity and ventilation. Unconditional orchards should be filled with water by means of small furrow irrigation. 3, protect the drought Irrespective of which method is adopted, effective measures must be taken after irrigation or after rainfall to ensure a steady and adequate supply of soil moisture and to prevent soil moisture from fluctuating and fluctuating too much and affect fruit development. Security measures: a. Timely cultivating loose soil, timely cultivating loose soil after irrigation and after rainfall, removing weeds, reducing water consumption and evaporation loss; b. Coverage and conservation can be implemented in the orchard before the onset of drought, wheat straw, cut green manure, straw mulching, not only reduce evaporation, but also reduce the ground temperature; c, plastic film cover, protect the drought, inhibit weeds. 4, timely drainage The fruit growers in the production only pay attention to irrigation and neglect the misunderstanding of drainage. Apples have accumulated water in the orchards in the event of fruit bulge and afterwards, in the event of heavy rain or continuous rain. The root activity of fruit trees is limited, resulting in cracking and early defoliation, affecting the fruit quality and yield. It must be drained in time to prevent waterlogging.
