不同种植方式对旱地玉米耗水规律及水分利用效率的影响
Effect of Different Planting Modes on Water Consumption Laws and Water Use Efficiency of Maize in Dryland
摘要
Abstract
Choosing nongda 108 and zhengdan 958 as maize varieties under drought condition ,the effect of different planting modes （flatten culture, ridge culture, ridge forming and film mulching） and different planting grain numbers （single grain sowing, double particles sowing ）on water consumption laws and water use efficiency of maize was studied.The results showed that between the same variety ,water consumption of ridge forming and film mulching was larger than that of flatten culture and ridge culture from jointing to watery stage, but was lower than that of flatten culture and ridge culture from watery to maturity stage.On the whole ,water use efficiency of zhengdan 958 was higher than that of nongda 108 ,and there was no differences between single grain sowing and double particles sowing. So using ridge forming and film mulching and choosing right varieties were the effective ways to improve the drought resistance and guarantee yield of maize.关键词
