【摘要】 杂交水稻"新混优6号"可以将父母本种子按照一定的比例混合,按照商品水稻生产的方法,育秧移栽、机械插秧或机械直播等方法进行种植。开花时,割叶、喷施"920",并赶粉,在母本授粉后,通过喷施一定浓度的苯达松杀死父本,并机械化收割。入库前通过色选技术去除少量残留的父本,从而达到杂交水稻制种的全程机械化。该文从机械直播、育秧移栽、机械插秧等几个方面分别介绍"新混优6号"机械化混播制种技术。更多还原

【Abstract】 Hybrid rice Xinhunyou No.6 could be cultivated by mixing male and female parents and performing seedling raising followed by transplanting,mechanical planting or mechanical direct seeding according to the production methods of commercial rice.During flowering stage,leaf cutting,application of "920" and pollination were conducted;after pollination,bentazon with a certain concentration was sprayed to kill the male parent;and the hybrid rice was harvested mechanically.Before storage,color separation was performed to remove little remaining male parent,thereby achieving whole-process mechanization of hybrid rice seed production.This study introduced mechanized seed production of Xinhunyou No.6 through mixedseeding from the aspects including mechanical direct seeding,seeding raising followed by transplanting and mechanical planting.更多还原
