摘　　要：通过观测板栗的根、枝、叶及栗园土壤水分含量的动态变化发现 :根、枝、叶组织水分含量的变化随着栗园土壤含水量的变化而变化 ;30cm土层为板栗根系的主要吸水层 ;北方山地栗园 ,春季每 1 5～ 2 0天需要进行一次灌水 。It was found after observation and measurement that the moisture content in the root, stem and leaf of chestnut dynamically changed with the change of moisture content in the orchard soil. The 30cm soil layer is the main water-absorbing zone. In spring, irrigation is needed every 15-20 days in chestnut orchards in north mountains for growth and development of chestnut trees.
