摘要
以籼型杂交水稻组合培两优986为试验材料,采用机械插秧和人工手插种植方式对比,研究机插水稻的生育特性和产量形成特性。结果表明:机插的齐穗期比手插晚2d,在分蘖盛期、孕穗期、抽穗扬花期、成熟期机插的单株地上部分干重较手插分别提高了5.98%、32.36%、45.93%、24.52%。机插稻的高峰苗较人工手插出现期偏迟,但机插稻约在播后41d分蘖明显增加,单位面积的分蘖总量也显著提高,群体增长较快。机插稻的成穗率为60.54%,较手插有所降低。机插较手插显著提高了单位面积的有效穗数,机插比手插的理论产量和实际产量分别增产11.40%和2.73%。
With the indica hybrid rice combination Peiliangyou 986 as the test material, growth characteristics and yield formation of the rice mechanized transplanting（MT） were studied by using the comparison of mechanized transplanting with manual transplanting（ TMT）. The results showed that ： the fully heading stage of MT later 2 d than that of TMT, and the dry weight of the plant on the ground with MT in the fully tillering stage, booting stage, fully heading stage, maturity stage increased by 5.98% , 32.36% , 45.93% , 24.52% , respectively. The tillering peak of MT appeared later; however, rice tiller of MT significantly increased at about 41d after sowing, and tillers per unit area of MT increased significantly, groups volume grew rapidly. The rice panicle rate of MT was 60.54% , lower than that of TMT. Compared TMT, MT significantly improved the effective panicles per unit area, the theoretical yield and actual yield increased 2.73% and 11.40% , respectively.
