Research of Astragalus mongholicus Water Consumption and Irrigation System in Arid Region
摘要
Abstract
[ Objective] To study water consumption and irrigation system of Astragalus mongholicus in arid region. [ Method] With two years A. mongholicus as object,an experiment was carried out on irrigation system and water consumption during whole growth stage in Guhai station in Zhongning,Ningxia Province. [Result] A- mongholicus turn green at March,plant height of 5 cm,and harvesting at September with height of 120 cm; yield is higher with irrigation quota about 5 100 - 5 700 m /hm ; at 3 6004 050 m / hm , it is more economic. Irrigation scheme is that irrigation quota 900 mJ in early April, 1 125 in3 in early May,l 200 m' in mid June,l 050 m3 in later July,l 200 m3 in winter. Total irrigation quota is 5 475 m /hm2 and water consumption is 7 350 -8 250 mVhm2. [Conclusion] The water consumption,optimum irrigation amount,times and quota of A. mongholicus during growth period was studied, which will provide technique support for planting and irrigating A. mongholicus in arid and semi-rid region.关键词
