免耕少耕法推行以后土壤表层0～5cm土壤有机质富集和植物养分富集,提高了微生物活性,并影响近地表层土壤的酸度和氧化还原状况,这些因素的改变影响了土壤肥力性质、供肥状况、肥料中养分的去向与利用率.因此,就需要采取与之相适应的新的栽培管理方法.本文侧重于水旱轮作制免耕少耕条件下的土壤肥力和施肥问题.
The soil organic matter enrichment and plant nutrient enrichment in soil surface 0 ~ 5cm after the no-till tillage method promoted the microbial activity and affected the acidity and redox status of the near-surface soil. The changes of these factors affected the soil fertility, The condition of fertilizer supply and the utilization and utilization of nutrients in fertilizers.Therefore, we need to adopt a new method of cultivation and management.This paper focuses on soil fertility and fertilization under no-tillage and tillage conditions.
