杂交水稻制种母本机械点播试验

Mechanical Direct-seeding of Female Parent in Hybrid Rice Seed Production

通过杂交水稻制种母本机械点播与传统人工插秧的对比试验,结果表明,母本机械点播的全生育期比传统人工插秧早熟5 d,基本苗、最高苗数和有效穗数均显著高于传统人工插秧;但其结实率却显著低于传统的人工插秧;制种母本的产量两者相当。机械点播能减轻劳动强度的同时,每667m^2还可节约生产成本248.4元。

The comparison experiment of female parent mechanical direct-seeding and artificial transplanting were carried out,results showed that compared to artificial transplanting,mechanical directseeding shortened growth period 5d,increased significantly the basic seedling number,maximum tillers and effective panicle number were increased significantly,reduced seed setting rate the yield performance none significant difference.Mechanical direct-seeding also reduced labor intensity and labor cost by 248.4 Per 667m^2.
