秸秆还田方式对半干旱区黑土养分含量、酶活性及玉米生长的影响
Effects of Straw Returning Methods on the Black Soil Nutrient Content,Enzyme Activity and Maize Growth in Semi-Arid Regions
摘要
Abstract
To investigate the effects of different straw returning methods on black soil nutrient content,enzyme activity and maize growth in semi-arid regions,three treatment were designed:rotary tillage with straw removed from the field(RT),no-tillage with straw mulching(SC),and deep ploughing with straw incorporation(SP).The impacts of different straw returning patterns on soil physical and chemical properties,maize growth and yield were investigated.The results demonstrated that compared with RT,straw returning treatments significantly reduced soil pH and bulk density(BD)in each soil layer.In the 0-20 cm soil layer,soil nutrients and enzyme activities under SC and SP were significantly higher than those under RT.In the 20-40 cm soil layer,SP was significantly higher than the other treatments.During different growth stages,SP markedly improved root traits compared with SC and RT,with increases ranging from 11.48%to 68.73%and 3.59%to 43.16%,respectively,while SC only significantly enhanced root activity(17.86%)and root diameter(7.62%and 20.24%)compared with RT.Moreover,SP significantly increased stem weight,root-shoot ratio,and photosynthetic characteristics at stasseling stage and full maturity stage compared with RT and SC.Overall,SP substantially improved soil properties,promoted maize root and plant growth,and increased maize yield.关键词
