研究了免耕水稻早发及分蘖成穗特性，结果表明：免耕水稻的早发性，与免耕水稻浅插关系密切．栽插深度对不同耕法水稻分蘖性的影响有明显差异，免耕浅栽水稻具有稳定的分蘖成穗特性，成穗率高，在常规密度栽培下，其单株籽粒产量比耕翻浅栽、免耕深栽和耕翻深栽分别高４．７％、１５７％和２４９％．水稻的免耕栽培，充分利用了水稻浅插的正效应．
The characteristics of early heading and tillering of non-tillage rice were studied. The results showed that the no-tillage rice was closely related to the shallow insertion of no-tillage rice. The effects of depth of planting on tillering of different tillage cultivars were significantly different. Tillers of non-tillage shallow-lying cultivated rice had stable tillering and spike trait and high spike percentage. Under normal density, the grain yield per plant was higher than that of tillage , No-tillage and tillage planted were 4.7%, 15.7% and 24.9% higher respectively. Rice cultivation without tillage, take full advantage of the positive effect of rice shallow insertion.
