不同耕法对水稻根系生长影响的研究表明,少免耕能促进水稻根系生长,提高根系活力,延长根系寿命。土壤过松过紧都不利于根系生长。少免耕有利于促进根系向纵深发展,增加下层根量和地上部的干物质积累。下层根量与产量呈极显著的直线正相关。
The study on the effect of different tillage methods on the growth of rice roots showed that less tillage can promote root growth, increase root activity and prolong root life of rice. Soil too loose too tight are not conducive to root growth. Less tillage helps to promote the root system to develop in depth, increase the amount of lower roots and dry matter accumulation above the ground. The lower root volume and yield showed a significant positive linear correlation.
