秸秆覆盖夏玉米不同生育期耗水特性及水分利用效率研究
Water Consumption Characteristics and Water Use Efficiency of Straw -Mulched Summer Maize in Different Growth Periods
摘要
Abstract
Taking the compact type summer maize variety Chaoshi 1 as material,3 straw mulching quan-tities(0,0.6,1.2 kg/m2 )were set to study their effects on the soil moisture content in different depths and the water consumption content and water use efficiency (WUE)in growth period under the rain -fed condition. The results showed that the soil moisture content in the layer of 0 ~60 cm could be improved significantly by straw mulching at tasseling -silking stage;but it had little difference with control at filling -maturity stage. The soil moisture content in the layer of 60 ~120 cm was the maximum with the treatment of C1.2 ,followed by C0.6 treatment and the minimum in control.Straw mulching could reduce the water consumption at the seedling stages,but increase that at tasseling -silking stage.The water consumption had no obvious difference at joint-ing and mature stages.The total water consumption had no difference after covering.Under the same water consumption,straw mulching could increase the water use efficiency and yield.关键词
