土壤是农业生产的基础,监测各种农艺措施下土壤肥力变化动态,对改良培肥土壤,保证粮油稳步增产,具有十分重大的意义。为了搞清免耕及各种轮作制度下土壤养分变化规律,1982年以来,我们在砂娄黑土等土壤上进行了这方面的初步探索。
Soil is the basis of agricultural production. Monitoring changes in soil fertility under various agronomic measures is of great significance to improving soil fertility and ensuring a steady increase in grain and oil production. In order to understand the law of soil nutrients under no-tillage and various rotation systems, we have conducted a preliminary exploration in this area since 1982.
