| 摘 要： | 为了改善秸秆大面积焚烧现状、实现农业的可持续发展,采用大田试验研究了稻麦两熟制不同耕作方式与连续秸秆还田对直播稻田土壤结构和养分含量连续变化的影响。结果表明,秸秆还田能够显著降低土壤容重,土壤耕作方式对土壤容重变化也有影响;秸秆还田可以显著增加土壤有机质含量、土壤全氮含量以及0~7 cm土层速效磷含量,耕作方式对土壤有机质含量、土壤全氮含量影响显著,但是对土壤速效磷含量影响不显著。 |

| Abstract: | In order to improve the situation of straw burning in a large area and achieve sustainable development of agriculture,the influences of different tillage modes and continuous straw returning on soil structure and nutrient content in direct seeding paddy field were researched through field tests.The results revealed that straw returning could significantly reduce soil bulk density,and tillage mode also had an impact on soil bulk density;straw returning could obviously increase the content of organic matter,t... |
