摘　　要：采用大区对比的方法研究了水稻秸秆在不同处理条件下还田对水稻数量性状的影响。结果表明,各处理秸秆还田后水稻各处理株高相近;稻瘟病、胡麻斑病、褐变穗等病害的抗性明显增强,稻瘟病发病率降低20%,抗倒伏和抗早衰能力明显增强。随着秸秆还田量的增加,穗粒数、空瘪率呈递增趋势,千粒重呈下降趋势。Based on the regional comparison method, this paper studied the effects of rice straw returning to field on quantitative traits under different processing conditions.The results showed that the rice height of every treatments were similar. The resistance to the diseases of rice blast, brown spot disease and brown panicle were enhancell significantly. And rice blast incidence rate decreased by 20%. Lodging resistance and anti-premature decrepitude ability were also significantly enhanced. With the increase of amount of straw returned, spike grain number and empty flat rate showed increasing trend, and 1000-grain weight showed a downward trend.
