jujube irrigation
Water is one of the indispensable substances in the life activities of jujube trees. The more vigorous the physiological activity is, the higher the water content is, and the water content of root tip and tender shoot is 6090%. The water content of the leaf is 80%, and the water content of the trunk is 40%. Jujube consumes a lot of water in the process of growth and development, such as 125-1000kg for every 1 gram of dry matter produced by photosynthesis. At the same time, in order to adjust the tree temperature, jujube consumes a lot of water through transpiration. Water is also the medium of all biochemical activities in jujube. Such as fertilizer absorption, material transformation and transportation can not be separated from water.
Compared with other fruit trees, jujube trees are resistant to drought and waterlogging, but when there is too little or too much water in the soil, it will have a bad effect on its growth and development, so it should be watered or drained in time according to the situation.
