两种灌溉方式下棉花根域层不同土层耗水比例初探

Preliminary Analysis of the Water Consumption on the Different Layers of Cotton under Two Irrigating Techniques

应用中子仪对农六师芳草湖农场、农七师127团的不同灌溉方式下的棉花进行土壤水分监测,应用PROBE灌溉管理软件进行分析,选取一些稳定的耗水过程(在此期间无降水、无灌溉、根域层内无排水现象)作为研究对象。将根域分为四层,看不同灌溉方式下,各层耗水的比例关系。

Neutron apparatus has been used to investigate the soil water consumption with different irrigation techniques in Fang-cao-hu Farming Corporation of the Sixth Agricultural Division and the 127th Regiment Fanning Corporation of the Seventh Agricultural Division. The data was analyzed through the irrigation software of PROBE and some of stable water consumption process during which the subject being studied had been free from rainfall, irrigation and drainage among the different layers of roots was taken into account so that the rules of the amount of water nee- ded was found out. During the study, the root area has been divided into four layers, so that it was easier to find out the rate of water consumption under different irrigating techniques.
