以杂交稻组合Ⅱ优673的亲本Ⅱ-32A和福恢673为材料,以久保田6行步行式插秧机为插秧机械,设置每公顷用种量15.0,22.5和30.0 kg 3个处理,以人工移栽母本每公顷用种量22.5 kg为对照,研究杂交稻制种母本机械化插秧的效果和产量表现。结果表明,久保田行走式插秧机可以实现有序插秧,能满足杂交稻制种母本机械化插秧的要求;机插母本分蘖速率加快,单丛最高苗数和有效穗数增加,但成穗率降低;机插对母本生育期影响较小,但抽穗比手插集中;每公顷用种量22.5和30.0 kg机插处理每平方米穗粒数与手插对照相当,但结实率增加,产量增加;母本机插在育秧和插秧2个方面合计比手插节约成本863.75~1 027.85元/hm2。母本机插可实现杂交稻制种高效、高产、稳产的目标。
The hybrid rice combination Ⅱ-673 parents Ⅱ-32A and Fuhui 673 were used as the material, and Kubota 6-row walk-type rice transplanter was used as the transplanting machine. Three treatments of 15.0, 22.5 and 30.0 kg per hectare were used, Planting per hectare with the amount of 22.5 kg as a control to study the effect of hybrid rice seed production and mechanization of transplanting performance. The results showed that Kubota walking-type transplanter can realize the transplanted seedlings in order, which can meet the requirements of mechanized planting of hybrid rice seeds. The tillering rate of mungbean was accelerated and the highest seedling number and effective panicle number of single cluster were increased. However, Lower than that of the control group. However, the effect of mechanical plug on the female reproductive period was less, but the heading was more concentrated than that of the hand plug. The spikes per spike per hectare were equivalent to those of the control group at 22.5 and 30.0 kg, but the seed setting rate increased, Increase; the mother machine inserted in the two aspects of seedling and transplanting than the total cost savings of 863.75 ~ 1027.85 yuan / hm2. The mother machine inserted to achieve hybrid rice seed production efficient, high yield, stable production goals.
