干旱胁迫对辽西半干旱区玉米生长和产量的影响
Effects of Drought Stress on the Growth and Yield of Maize in Semi-arid Area of West Liaoning
摘要
Abstract
To provide theoretical basis for reasonable irrigation,effects of drought stress on the growth,yield and water use efficiency of maize were studied with Danyu 77 as the test crop in western arid region of Liaoning province.The results showed that the growth and yield of plant were restrained under drought stress,and the situations were worsen due to the increased aridity; seedling stage,elongation stage and heading stage of plant growth were susceptible to drought stress while during the postulation stage,the adverse effect was relatively small; water use efficiency under the treatment with light drought during the seedling stage was higher than check treatment,but water use efficiencies of other treatments were lower and decreased with drier condition.Therefore,when the water resource is scarce in the research area,light drought in seedling stage and drought stress in postulation are recommended,which could avoid the effect of drought in elongation stage and heading stage.关键词
