混播制种是指将杂交水稻的父、母本亲本种子混合播种，扬花授粉后再通过化学方法去除父本，收获杂交种的一种机械化制种方式1]2]3]，是杂交水稻制种技术的发展方向。本文从机械旱直播、机械水直播和机械插秧等3个方面阐述了杂交水稻混播制种从播种到收获的全过程。

The Production Technology of seeds by mechanize of Hun Zhi NO. 1

Mixed Planting Breeding refers to mixing the Parents’ seeds of Hybrid Rice, and sowing, get rid of the male parent through chemical methods after flowering and pollination, gain the seeds of Hybrid Rice, which is the mechanized way of seed production, and the development direction of hybrid rice seed production technology. This article expatiates on the entire process of Mixed Seeding of Hybrid Rice from three aspects such as drought mechanized-planting, water mechanized-planting, and mechanized-transplant seedlings.
