Fruit trees are watered with great care, spring pouring is good, summer pouring is less, and autumn is not enough. As far as the apple tree is watered in spring, there are two periods to ensure the supply of water.
One is before the budding. In this period, the precipitation is less, it should be combined with fertilization for watering, one can promote the absorption of fertilizer, the second can promote the germination, flowering and fruiting of fruit trees, and the third can reduce the damage of light night cream.
Second, the new shoot speed is long-term. This period is the critical period of water demand. In actual production, whether fruit trees need watering depends mainly on soil moisture and drought. According to research, the field water holding capacity of fruit trees is 60% to 80%. The intuitive criterion is that the soil with a depth of 20 cm can be held in groups and landed. Being able to maintain such humidity indicates that the soil is still in good condition and there is no need to water it, otherwise it will need to be watered at the right time. Watering should be controlled to 30 to 50 cm deep in the soil, avoid flooding, to prevent the new shoots from growing, affecting flower bud differentiation.
