不同种植方式对丘陵地小麦田土壤水分、产量及水分利用效率的影响
Effects of Winter Wheat Planting Manners on Soil Water,Yield,and Water Use Efficiency in Hilly Land
摘要
Abstract
The aims of the research were to evaluate the effects of different planting manners in soil water,yield,and water usage efficiency(WUE) in hilly land.Experiments Using randomized block method were carried out by using Lin-han 536 as material.The result shows narrow row sparse drilling technique(C1),drilling beside plastic film(C2),ridge sowing(C3) have reduced more significantly in the 0-240 cm layer in the whole growth period,compared with normal drilling seeding technique(CK),there were significant alter ations in 0-120 cm,enhancing the water usage efficiency.C2 was contributed to protecting middle soil water before jointing.There was a significant difference in the total water consumption among the three treatments in the sequence C2>C3>CK>C1.Jointing reached the maximum water con-sumption which is 27.58% ~37.56% of the total water consumption.Grouting rate and aboveground biomass of C2,C3 were higher than C1,CK.Thousand kernel weight,yield,utilization rate of rainfall showed the trend of C2 >C3 >C1 >CK.All of those analysis clarify C2 promote the change of soil water,enhance grouting rate,abovegroud biomass,utili-zation rate of rainfall,thousand kernel weight,which result in the increase of yield finally.关键词
