浅埋滴灌水氮配施对冬小麦生长发育、产量及水分利用效率的影响
Effects of water and nitrogen application on winter wheat growth,yield,and water use efficiency under shallow buried drip irrigation
摘要
Abstract
[Objective]This project aims to discuss the effects of shallow burial drip irrigation belt,irri-gation and nitrogen application on the growth,yield and water use of winter wheat.[Methods]In this study,three factors were set up:soil depth(0 and 5 cm),irrigation amount(270,315 and 360 mm),and nitrogen application(195,255 and 315 kg/hm2).[Results]The results showed that,when the irrigation quota was 315 mm and the nitrogen application rate was 255 kg/hm2,the yield,irrigation water use efficiency and nitro-gen fertilizer partial productivity increased most obviously.Shallow buried drip irrigation increased the plant height and leaf area index of winter wheat by 5.58%and 16.77%,respectively,and the yield,irrigation wa-ter use efficiency and nitrogen partial factor productivity significantly increased by 8.32%,8.20%and 8.16%,respectively.The net income of shallow buried drip irrigation increased by 1,092 yuan per hectare on average compared with that of no soil cover drip irrigation(0 cm).The net income of shallow buried drip irri-gation with 315 mm of water and 255 kg/hm2 of nitrogen was the highest,(10,883 yuan/hm2).[Conclu-sion]The best irrigation and fertilization schemes are as follows:315 mm of irrigation water and 255 kg/hm2 of nitrogen under shallow drip irrigation.关键词
