杂交水稻制种系列机械化技术研究总结

通过１９９０～１９９２年３年对杂交水稻制种系列机械化配套制种技术研究，结果表明，由于工效提高，保证了大面积适时栽植，花期相遇良好，异交结实率提高，同时可减少收获损失，种子产量增加１９．８％，为我国实现规模经营制种机械化提供了经验．

A Summary Report on the Technique of the Serial Mechanization in Hybrid Rice Seed Production

The technique of the serial mechanization in land tilling,seedling raising, transplanting, cultureal management,seed harvesting, cleaning and drying rice seed production was experimented on and demonstrated under an area of 10 ha for three years in 1990-1992. The results indicated that the trans- planting labor efficiency was 12 times, and the harvesting labor efficiency 51.2 times that of handling by hand, and for the mechanization guaranteed the timely large-scale transplanting,the synchronization of flowering was more easily reached thin the outcrossing rate increased by 3.5%, furthermore, since there was less loss happened in harvesting, 75kg more seeds could be gained per ha.The successful experiment on serial mechanization in hy- brid rice seed production the basis and accumulated experience for extending the technique nation wide.
