Detailed Explanation of Key Techniques for Irrigation and Drainage of Jujube Trees

Water is one of the indispensable substances for the life activities of jujube trees. The more vigorous the physiological activity of a part, the higher its water content: the water content of root tips and tender shoots is 60-90%. The water content of leaves is 80-85%, and the water content of the trunk is 40-55%. During its growth and development, the jujube tree consumes a large amount of water; for example, photosynthesis consumes 125-1000 kg of water for every 1 gram of dry matter produced. At the same time, to regulate tree temperature, the jujube tree consumes a large amount of water through transpiration. Water is also the medium for all biochemical activities within the jujube tree. For example, the absorption of fertilizer, the transformation and transport of substances, and so on, cannot be separated from water.

Compared with other fruit trees, although the jujube tree is drought-tolerant and waterlogging-tolerant, when there is too little or too much water in the soil, it will have adverse effects on its growth and development, so watering or drainage should be carried out promptly according to the situation.
