Although jujube trees are more resistant to drought, excessive drought may cause irregular sprouts, and the growth of jujube heads and jujube cranes will decrease, which will cause a large number of flowers to fall and fruit to fall, resulting in smaller fruit and deteriorated quality. Therefore, in order to improve the fruit setting rate, increase the yield and quality, it is very necessary to make the jujube water storage project and timely irrigation, especially the fresh food species, the water requirement is relatively large. During the irrigation period, it is determined according to the weather conditions and the growth of the tree. The critical periods for jujube tree water and irrigation are as follows: 1. Germination water The roots of pre-emergence jujube trees have begun to move, and the shoots are about to germinate. In this period, irrigation is combined with fertilization to promote the development of various organs of jujube trees. 2. Water before flower Should be carried out before flowering, when the temperature is high, evaporation is large, timely irrigation with irrigation can make the flower open normally, avoid causing burnt flowers, falling flowers, in order to improve fruit setting. If there is too much rain and the humidity is too high, irrigation should not be carried out so as to avoid falling. 3. Set fruit water Shortly after fruiting, the young fruit is very sensitive to water, and the temperature is often high at this time, which is another critical period for the tree to be water. If there is a lack of water at this time, the fruit drop will be serious. Therefore, it is also called water conservation. 4. Color change water The fruit enlargement period combined with fertilization and irrigation can accelerate fruit enlargement and improve fruit quality. If water is lacking, it will directly affect the size and yield of fruit. 5. Frozen water In other words, irrigation before freezing can not only promote nutrient absorption in the root system, but also increase nutrient accumulation in the tree. It also increases the ability of jujube trees to withstand cold in winter. Disclaimer: Some articles in this website have been transferred from the Internet.
