以杂交粳稻组合常优5号为材料,采用10行水稻制种专用型插秧机,设置机插和人工移栽的对比试验,分析了机插和人工移栽在叶龄动态、生育期以及制种产量等方面的差异。结果表明:机插移栽和人工移栽的母本叶龄动态、生育期、基本苗、有效穗数、穗形和制种产量等无显著差异,但机插移栽的结实率显著高于人工移栽;机插移栽每公顷节省移栽费用2 257.5元,显著节省人工,提高制种效率。
The hybrid japonica rice combination Changyou 5 was used as the material, and 10 lines of rice seedling special-type rice transplanter was used to set up a comparative experiment of machine insertion and artificial transplanting. The effects of machine-inserted and artificial transplanting on leaf age dynamic, Differences in yield and other aspects. The results showed that there was no significant difference in leaf age, growth period, basic seedling, effective panicle number, spike shape and seed yield of female transplanting and transplanting, but the seed setting rate of transplanting was significantly higher Artificial transplanting; Machine transplanting transplanting cost savings per hectare 2 257.5 yuan, significant savings in labor and improve seed production efficiency.
