摘要
1986～1992年，从水稻少耕免耕的类型及生产效应比较研究了不同耕作法间的土壤理化性质，供肥特点，水稻根系的数量、质量和功能特点，水稻地上部分蘖和产量构成因素形成的生理特性，高产配套技术的特点等，结果表明少免耕的增产是由土壤效应、生理效应和耕作栽培技术效应3者综合作用所致。
The soil physio-chemical properties, nutrient supply. rice root number. root vigor and function, physiologcal characteristicsof tillering and yield components were researched comparatively for moderate or non-tillage. It is concluded that the yieldincrease for moderate or non-tillage result from the integrative effect of soil effect, physiological function and cultivationpractice. Moderate or non-tillage system can save labour, cost and water, increase yield and income. Moderate or nontillage can increase yield positively if it is done strictly according to the requirements.
