通过进行常规稻机械插秧时采用30cm×21cm(疏)、30cm×16cm(中)以及30cm×12cm(密)三种不同插植规格对比试验,比较分析常规稻机械插秧在相同的品种、田块、育秧方法、插植深度、抓秧面积及田间技术管理时三种不同插植规格的生长期和产量差异。试验结果表明:常规稻机械插秧不同插植规格试验品种的全生育期一致,密规格对比疏规格或中规格的基本苗、最高苗数、有效穗数和平均产量都有明显增加,对常规稻机械化插秧技术的推广有现实指导意义。
The conventional rice mechanical transplanting was compared with the conventional rice mechanical transplanting in the same varieties by using 30cm × 21cm (sparse), 30cm × 16cm (medium) and 30cm × 12cm (dense) , The method of planting seedlings, the depth of planting, the area of grafted seedlings and the technical management of the field. The results showed that the whole growth period of the conventional rice varieties with different planting specifications was the same throughout the whole growth period. The density, density, seedling number, the effective spike number and the average yield were all significantly increased. The promotion of mechanized planting technology has realistic guiding significance.
