研究了在白浆型水田土的条件下，翻耙结合和免耕轻耙两种不同耕作方式的分蘖生产力。研究认为，在免耕轻耙情况下，由于泡田时间短，土壤硬度大，氮肥流失多，不利于水稻的初期生长，因而影响有效穗数和一穗粒数的增加；但是免耕轻耙既可保证水稻的浅插，又能增加水稻生长中后期的土壤通透性，有利于增强根系活力，提高水稻成熟度，千粒重远远高于对照。如果适当调整施肥方法和加强管理，可能成为土壤通透性差的水稻田创高产的新途径 This paper studied the tiller productivity of two different tillage ways, including the combination of turning and raking and no-tillage rake under the condition of white paddy soil. The results showed that under the condition of no tillage and light rake, the effective fringe number and the number of grains per spike affected the increase of the effective spike number and grain per spike due to short time of soaking, large soil hardness and excessive loss of nitrogen fertilizer, which was not conducive to the initial growth of rice. However, It can not only ensure the shallow insertion of rice, but also increase the permeability of soil in the middle and later stages of rice growth. It is beneficial to enhance root activity and improve the maturity of rice, and the 1000-grain weight is much higher than that of the control. If properly adjusted fertilization methods and strengthen management, may become a new way of high yield paddy fields with poor soil permeability
