How to Manage Water in Grape Maturity Period

  The principle of water management in grape ripening stage is to maintain a uniform water supply, and reduce the water supply appropriately in the later stage of ripening process, so as to improve the quality of grape, and also benefit the full expansion of fruit in the early stage of ripening. However, it should be noted that the water supply of grapes should not be too dry and wet. It should be avoided that the grapes are drought for a long time during ripening without irrigation. If the soil is drought-prone, it will be very difficult to replenish the water, and the fruit will crack when the amount of water is more than one.

How to Manage Water in Grape Maturity Period

  Generally speaking, it is necessary to keep a certain amount of water in the ditch for open-field grapes. When the border soil begins to whiten, it needs watering. The time and amount of each watering can be prolonged and reduced, so that the roots on the surface of grapes can gradually adapt to the climatic conditions of the ripening period, and prevent a large number of deaths of the roots on the surface due to excessive water loss, thus affecting the growth of grapes and branches and leaves. This is an effective prevention. The main measures to stop defoliation, yellowing and softening of grape fruits at ripening stage. For orchards with drip irrigation and sprinkler belts, water management is relatively easy.

  The water management of grape in greenhouse is mainly sprinkler and drip irrigation and keeping proper moisture in ditches. The best way is to keep the border surface dry. Greenhouse and rain-shelter cultivation can avoid fruit cracking due to excessive water caused by sudden heavy rainfall, but also can not pay attention to water supply. Maintaining a certain level of water in border irrigation ditches and using drip irrigation are very good ways of water supply. At the same time, it can control the amount of water and irrigation according to the needs of grape ripening.
Because of thunderstorms and typhoons in mature season, it is necessary to do a good job of drainage to prevent flooding of garden land.
