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。
Eight varieties of early and late rice were selected at different growth stages to study the tillering traits of different varieties under the conditions of wide and narrow row and the equivalent machine. The results showed that the length of seedling transplanting rice was related to the performance of rice transplanter. The effect of mechanical intercropping on tillering of early rice was greater than that of late rice. The early tillering of early rice was slower than that of late rice, the tillering stage was longer, the tiller number per plant and effective panicle Under the same density, the tillers with wide and narrow rows were faster and slower after the seedling stage, the width and width of the tillers were lower, and the width and width of the tillers could increase the tillering and the effective panicle number and the rice yield. Adaptability of the machine inserted differences, short growth period, strong tillers tillers per plant and more varieties of spikes suitable for machine inserted; Machine inserted on rice Huanmiao should be able to improve the performance by improving the transplanter.
