| 摘 要： | 依据国家科技攻关旱农张北试区定位观测资料，分析了栗钙土燕麦田的水分运动与周年平衡。结果表明，燕麦对冀北高原农田水分环境具有较好的生态适应性。燕麦田周年土壤水分呈负平衡，水量亏缺２８．３ｍｍ，非生育季节水分蒸发４０．２ｍｍ，占０～１６０ｃｍ土体贮水量的２２．５％，成为主要水分损失方面。燕麦田生育季节水分呈正平衡，盈余１１．９ｍｍ．重视生育季节的田间水分蓄保是提高燕麦田水分利用效率的技术核心。

| Abstract: | The water dynamics and annual balance of chestnut soil in oat field were studied in this paper based on the moisture data obtained from the fixed plot experiment in the na nonal dryland farming experimental station of Zhangbei. It showed that oats were adaptable to the water condition of the Plateau in North Hebei.The water reserve in the oat field lost28. 4mm during a year and 40.2mm during the non-growing season,but there was a surplus of 11.9mm water during the growing season.Water reservation during the growing season is important to raise the wateruse efficiency of oats. |
