【摘要】 选择不同生育期的早、晚稻品种各8个,研究宽窄行和等行机插秧条件下不同品种的分蘖特性。结果表明:水稻机插秧缓苗期的长短与插秧机的性能有关;机插对早稻分蘖的影响大于晚稻,早稻比晚稻分蘖起始慢、分蘖期长,不同品种的单株分蘖数和有效穗数差异较大;在相同密度的情况下,宽窄行机插处理水稻在缓苗期后分蘖发生快、消亡慢,宽窄行机插有利增加水稻分蘖、有效穗数以及提高水稻产量;不同品种的机插适应性有差异,生育期短、单株分蘖力强和单株有效穗多的品种适合机插;机插对水稻缓苗的影响应该可以通过提高插秧机性能得到改善。更多还原

【Abstract】 This paper chose eight varieties of early season rice and late season rice on different growth period,and discussed the tiller characteristics of different varieties under the mechanical transplanting of wide-narrow row and equivalent row.The results showed that the slow growth phase length of rice seedling is related to the transplanter function.Utilized machine transplanting,effect on early rice tiller was larger than that of late rice.Tiller start of early rice was slower,tillering stage was longer than late rice under machine transplanting.The differences of tillers and effective panicles were bigger in different varieties.In the same density,treatment of wide-narrow row transplanting tillering fast and die slowly after slow growth phase,wide-narrow row transplanting enabling increased tiller,panicle number and increase the yield of rice.Different varieties had significant difference in adaptability of machine transplanting,the varieties that a plant tiller ability were stronger,and its a plant number of effective panicles were much more,adapt to machine transplanting.The effect of the machine transplanting on the slow growth phase should be better by improving of rice transplanter.更多还原
