Enter summer, the temperature is higher, tree body and soil moisture evaporation are larger.At this stage, water should be properly controlled to facilitate the formation of flowers;This period if the amount of water is too large, will stimulate the vegetative growth is more exuberant, has been capped in the short branches easy to bud germination and take out the autumn shoot, on the formation of flower buds is very unfavorable.In the actual production, whether should water, should depend on orchard moisture content and tree potential.

First, to see the underground lack of water, you can dig 20 cm deep soil layer to see the moisture content, dug out of the soil can hold a group, not scattered on the ground, that the moisture content is moderate, you can temporarily not water.On the contrary, can not hold into a group, it means that the lack of moisture, should be watered every other line, as soon as possible to remove the drought.

Second, if the tree full fruit, the tree is not too abundant, even if not lack of moisture, because the temperature is high, the tree is weak, in order to grow the fruit, high temperature, also should be watered.In this case watering, the tree will not sprout, will not affect the flowers.

Third, if the tree half tree fruit, or tree potential prosperous, the tree that year more than 1 chi long shoots more, as long as the soil is not short of moisture, it is best not to water;No matter how hot the weather is, how high the temperature is, as long as watering, it will make a large number of new shoots grow out, consume nutrients, affect the flowers.

Fourth, watering must give fertilizer.Most mineral nutrients need to be dissolved in water to be absorbed by the fruit tree.Under the action of transpiration pull, water carries nutrients from the root system to all parts of the tree, water evaporates, nutrients remain in the leaves for photosynthesis, making organic nutrients.Empty water can only meet the demand of tree body for water, but not for nutrient.Therefore, whenever watering, it must be combined with fertilization.
