Effects of Planting Methods on Grain Yield and Quality of Late Rice Culitvar Wufengyou T025

A hybrid late rice cultivar(Wufengyou T025) was used to study the effects of planting methods on grain yield and quality.The results showed that both planting and management methods had significant effects on grain yield and quality.The grain yield under high-yielding management was higher than that under conventional management.Of the 4 different planting methods,the manual transplanting and tillage cast transplanting had a higher grain yield followed by mechanical transplanting,while the no-tillage cast transplanting had the loweest grain yield.Among different planting methods,the grain yields were mainly affected by panicles number.Under the manual transplanting and tillage cast transplanting,the increase and decrease of tiller numbers were more stabile,the percentage of earbearing tiller,the dry matter production at the early stage and the root dry weights per plant were high,the proportion of deep roots from 10 to 20 cm was large.Under the mechanical transplanting and no-tillage cast transplanting,the tillering speed at the early stage was low and the number of effective panicles was small.The study also showed that planting methods had great effects on the milled rice rate,chalky grain rate,degree of white core,protein content,and so on.
