灌溉方式对大豆光合性状及土壤水分利用率的影响
Effects of Irrigation Modes on Photosynthetic Characters and Water Use Efficiency of Soybean
摘要
Abstract
Three irrigation modes of uniform irrigation( UI) .fixed furrow irrigation( FFI)and alternative furrow irrigation(AFI) were operated at flowering,podding and seed filling of soybean,with single furrow irrigation amount of 60,45 and 30 mm respectively, with no irrigation as control. Irrigation increased photosynthetic rate and yield of soybean evidently. The soil water use efficiency of AFI 45 mm was the highest,and there were no significant differences of the photosynthetic rate at R4 and seed yield between AFI 45 mm and AFI 60 mm. Hence, AFI 45 mm was the best irrigation mode base on the view of yield increasing and water saving.关键词
