摘    要:研究了在两种种植密度下,精量穴直播种植方式与人工撒播、人工抛秧和机械插秧种植方式的产量对比,以研究精量穴直播早稻的产量形成特性。结果表明:两种密度的精量穴直播的实际产量比人工撒播和机械插秧的实际产量分别增产24%~28%和8.2%~11.6%,精量穴直播的实际产量比人工抛秧的实际产量稍有增加;精量穴直播较人工撒播、人工抛秧和机械插秧的有效穗数分别增加0.9%~7.0%、3.5%~9.7%和7.4%~13.9%,收获指数分别增加22.7%~37.2%、17.2%~26.6%和0.8%~12.7%,精量穴直播结实率较人工撒播的增加8.6~8.73个百分点, 精量穴直播较人工撒播和机械插秧的单蔸穗质量分别增加17.84~18.76 g和2.15~3.07 g,精量穴直播较人工撒播和机械插秧的群体穗质量分别增加1.225~1.430 t/hm2和0.447~0.628 t/hm2。

关 键 词:农业机械,收获指数,精量穴直播,早稻,产量

Abstract:Yield formation characteristics of the early rice planted with precision hill-drop drilling machine were studied by comparing the yields of two-density precision hill-drop drilling with manual broadcasting,manual seedling broadcasting and mechanized transplanting.The results showed that compared with manual broadcasting and mechanized transplanting,the yields of precision hill-drop drilling with two densities increased significantly by 24% -28%and 8.2%-11.6%,respectively,and increased slightly compared with...
Keywords:agricultural machinery  harvest index  precision hill-drop drilling  early rice  yield
