| 摘 要： | 为计算保护性耕作条件下农田棵间蒸发量,以一年两熟地区保护性耕作体系试验数据为基础,进行了以叶面积指数、地表秸秆覆盖率、地温比值、地表含水量等参数为自变量,日棵间蒸发量为因变量的4种回归分析.结果表明,影响日棵间蒸发因素强弱顺序依次是地温比值、地表含水量、叶面积指数及地表秸秆覆盖率,并建立了一年两熟地区保护性耕作条件下的蒸发积分模型.

| Abstract: | Based on the data of the conservation tillage system research in two crops one year, this paper analyzes four regression equations which independent variables are leaf index, ground residue coverage, radio of the soil temperature and air temperature, surface water content, and induced variable is daily evaporation. The results show that the factors impacting daily evaporation include radio of the soil temperature, surface water content, leaf index and residue coverage, which are listed in the order from higher level of effects to the lower level. The integral model for evaporation is established under conservation tillage in two crops one year. |
