Should fruit trees be watered in summer?

In a densely planted orchard less than 400 meters above sea level. It doesn't rain for two or three weeks in June and July. 1~3 When the leaves appear soft at noon, water them. Let the trees drink well and not be full, which not only requires less investment, but also has good effect, which not only meets the water demand of fruit expansion, but also promotes the differentiation of flower buds and inhibits peeling.

The data shows: "A fruit is about 90% water. Without water, there is no tree, without light, there is no fruit; There is no harvest in water, and there is less harvest in fat. " But the more water the better. Should not be watered, when to water, how much to water, should be flexible according to the following points:

1. During the whole growing period, listen to the weather forecast according to the soil moisture and water it in time according to the drought and precipitation.

Second, decide whether to water the trees according to their strength and the number of fruits. If the trees are lush or the fruits are few, the watering times can be reduced; If the tree is weak or bears much fruit, water it more.

Third, different watering times have different effects. For example, on a tree, there is only one growth center at a stage, which is the "peak period". April and September are the peak periods of root growth. When watering, the root system grows well. May and August are the peak of branch growth (May is the peak of spring shoot growth and August is the peak of autumn shoot growth). At this time, the watering branches grow longer, which can prolong and delay the capping time.

4. For Red Fuji, even if the water is controlled before June 30th, there will be no cracks in the later period. However, in the month from July 20th to August 20th, because of the highest temperature and large evaporation, if there is water shortage in the ground, the leaves will pull the water in the young fruit onto the leaves and evaporate it, so that the young fruit will stop growing. Once watered or drenched in rain, the pulp will be crisp and expand rapidly, while the peel will absorb water slowly, resulting in microcracks on the fruit surface. So be sure to keep the soil water supply this month.

Five, fruit trees bear more fruits, need more water, and are not drought-tolerant. For example, if two trees are the same, one tree bears 100 kg and the other tree does not bear fruit, then the tree bearing 100 kg needs about 100 kg more water than the tree without fruit. The same drought, no fruit trees will not dry up.

Six, in addition to the fruit trees after defoliation and before germination, watering should be properly controlled from June to July. If the weather is dry and the soil is too short of water, water it. Irrigation should be balanced throughout the growing season. A row of fruit trees, one on each side, is watered in this row during drought, but not behind the trees (between rows); After half a month, when it doesn't rain at high temperature, water it for the second time, and don't water the back; Water it again for the third time, without watering the back. Because only a part of the roots are watered at a time, it can not only prevent peeling caused by drinking too much, but also avoid water shortage.
