摘要
通过2009年在黑龙江省杜蒙县一心乡进行的田间小区试验,研究了"大垄双行覆膜+膜下滴灌+垄向区田"和"行间覆膜+滴灌+垄向区田"两种技术集成措施在苗期、拔节期和灌浆期这三个生育期内灌不同量的水对玉米产量及其构成要素、水分利用效率等的影响,并分别提出了基于产量和水分利用效率的玉米不同生育阶段的最佳灌水量。
Based on field pilot experiment conducted in the Yixin Village of Dumeng County of Heilongjiang Province in 2009,the impacts on maize yield,composed elements and moisture use effectiveness of two technological measures,including both the film mulching with big ridge double-line ＋ drip irrigation under film ＋ ridge tillage and covering film between furrows ＋ drip irrigation ＋ ridge tillage,were researched for different irrigation water amounts during the three growing stages,such as seedling,jointing and milking grain,and the optimal amount of irrigation water was proposed separately for different growing stages based on yield and moisture use effectiveness in the study.
