研究了水稻制种不同育秧方式与母本不同基本苗对制种产量的影响。结果表明：父本采用旱育稀植育秧和旱育水寄两段育秧对制种产量的影响不显著；父本不同育秧方式与母本不同基本苗的交互作用亦不显著；而母本不同基本苗极显著影响制种产量。适宜的母本基本苗是２１４２～２４．１０万苗／６６７ｍ２，超过２４１０万苗，制种产量呈下降趋势。
The effects of different seedlings of rice seed production and different basic seedlings on seed production were studied. The results showed that there was no significant difference between the male parent and the female parent when the seedlings were raised by the nursery and sparse planting nursery stock and the dry seedling watering nursery stock. The interaction between the male parent and the female parent was not significant. Seedlings significantly affect the basic seed production. The suitable basic seedlings of 21.42 ~ 24.10 million seedlings / 667m2, more than 24 10 million seedlings, seed production showed a downward trend.
