In addition, about 15 days before picking, the peach fruit rapidly enlarges. At this time, if there is water shortage, the fruit development is small and the yield is low. Therefore, this period can not be short of water. However, it should not be too much, too much work, to prevent the fruit flavor from lightening. After harvesting fruit, it is not necessary to water in the fall and the soil should be properly arid. Moderate drought is conducive to flower bud differentiation and shoot ripening. Excessive water content can easily cause autumn shoots to be long and detrimental to flowering. However, excessive drought must also be properly watered to prevent premature leaf shedding. When the young peach orchards are dry, they can only water the tree trays. This method is simple and easy. Only by repairing the waterways and blisters, can it be irrigated by drinking water and the water quantity is sufficient. However, this method is often used to destroy the soil structure, the surface of the soil is easy to compact, and the loss of fertilizer is serious. When the water supply is insufficient, the wheel-like groove can be opened under the canopy projection, and the short ditch is connected between the plants. This method is more water than flood irrigation, and the degree of soil damage is lighter. The laying of underground pipes for surface irrigation can save water by 50% to 70%. Sprinkler irrigation is fixed and mobile.
