秸秆还田与地膜覆盖对绿豆水分利用效率及产量的影响
Effects of straw returning and plastic film mulching on water use efficiency and yield of mung bean
摘要
Abstract
[Objective]To determine the effects of straw returning and plastic film mulching on the water use efficiency and yield of mung bean.[Methods]Using mung bean variety Mengkelyu No.4 as the test material,four treatments were set up:straw returning combined with plastic film mulching(SP),straw returning alone(S),plastic film mulching alone(P),and no straw returning with no plastic film mulching(NSP,CK).The effects of straw returning and plastic film mulching on soil bulk density,soil porosity,soil water content,soil water storage,as well as water use efficiency,root architecture,yield and its components of mung bean were analyzed.[Results]Under the SP treatment,soil bulk density was significantly lower than that of other treatments(P<0.05),which decreased by 11.89%compared with the NSP treatment after harvest.Soil porosity,soil water content,and soil water storage were significantly higher than those of other treatments(P<0.05),increasing by 6.48 percentage points,5.20 percentage points,and 13.29%compared with the NSP treatment after harvest,respectively.Under the SP treatment,the root architecture indices,plant dry matter weight,and yield-related indices of mung bean were all significantly higher than those of other treatments(P<0.05).Compared with the NSP treatment,the total root length,total root surface area,and total root volume of mung bean increased by 42.02%,28.04%,and 22.63%,respectively.Compared with the NSP treatment,the water use efficiency,plant dry matter weight,number of pods per plant,number of seeds per pod,100-seed weight,and yield of mung bean increased by 27.72%,40.68%,14.82%,11.72%,19.19%,and 24.08%,respectively.[Conclusion]Compared with straw returning alone or plastic film mulching alone,straw returning combined with plastic film mulching can significantly improve soil physical properties,enhance soil water storage and moisture retention capacity,promote the growth and development of mung bean roots,increase plant dry matter weight,and ultimately improve mung bean yield and water use efficiency.关键词
