摘要
本文通过对夏玉米根系伸展深度和不同深度土壤含水量分布资料的分析,利用动态模拟方法,分析了夏玉米根系吸水的分布规律,分析了根系吸水与其影响因素之间的关系。用多元问归分析方法拟合了玉米根系吸水的数学模型,利用所得到的玉米根系吸水模式对田间土壤水分动态进行了模拟。模拟值与实测值比较结果表明具有一定的精度。
In this paper, through analysing for the data of toot develop ment depth and soil water content in different depthos, and the root water upta Re dynamics was simulated in summer corn growing seasons, based on this, the relationship between the rote of root extractim and its influenceel factors was analyzed, too The model of water uptake by roots of summer corn was establisheel, and It was tested, the resule showed that the simnlated data are good greenment with the meascned data in fidd condition.
