在杂交水稻集约化制种中 ,将母本机械直播与湿润育秧大苗手栽 (简称手插 )两种母本定植方法进行对比试验。结果表明 ,母本机械直播比手插可增产 12 .5 % ,节约母本定植开支 830元 hm2 。采用母本机械直播技术还可大大提高劳动效率 ,降低劳动强度 ,在集约化制种时更能确保母本基本苗 ,显示出诱人的应用前景。 In intensive hybridization of hybrid rice, the maternal mechanical live and wet seedling transplanting seedlings planted (referred to as hand inserted) two female parent colonization methods were compared. The results showed that the maternal mechanical live broadcast increased by 12.5% ​​compared with the hand insertion, which saved 830 yuan hm2 for female parent planting. The use of mother live broadcast technology can also greatly improve the work efficiency and reduce labor intensity in the intensive seed production more to ensure that the basic seedlings mother, showing attractive prospect.
