摘要:
为改良土壤结构，提高土壤生物活性，开展定位试验，设置旋耕秸秆不还田、免耕秸秆覆盖还田和深翻秸秆还田3种方式，测定玉米生育期内，不同耕作与秸秆还田方式对根际微生物数量及酶活性的影响。结果表明：各处理苗期至吐丝期，根际微生物数量和酶活性迅速增加，吐丝期达到最大值后逐渐降低。和旋耕秸秆不还田相比，免耕秸秆覆盖还田和深翻秸秆还田可提高玉米生育中后期菌群数量及酶活性，且深翻秸秆还田作用效果更为显著，说明深翻秸秆还田对改良土壤结构，提高土壤生物活性效果更好。
Abstract:
In order to improve soil structure and improve soil bioactivity,we investigated the effects of different tillage and straw return methods(conventional rotary tillage without straw return,no tillage with straw mulching and deep plowing with straw return) on rhizosphere microbial quantity and enzyme activity by position test .The results showed that each treatment at seedling to silking stage,the rhizosphere microbial quantity and enzyme activity increased rapidly and reached the maximum value at silking stage,which decreased gradually after silking stage.Compared with rotary tillage without straw return,no tillage with straw mulching and deep plowing with straw return increased the microbial number and enzyme activity.And the effects of deep plowing with straw return was more significant,which suggested that effects of deep plowing with straw return on improving soil structure,increasing soil biological activity and promoting maize yield was better.
