摘要
当不育系抽穗５％和４０％时，每公顷分别喷施花信灵４５０ｇ．加水５２５ｋｇ：或在不育系幼穗分化第７期和第８期时，每公顷分别喷４５ｇ调花宝。对水６００ｋｇ．结果表明。花信灵和调花宝均能明显增加不育系的午前花、柱头外露以及异交结实率等良好效应，提高制种产量。
g/hm2 of Huaxinling was prayed with 525kg/hm2 of water respectively when the panlclesof MS lines were 5%emerged and 40%,45g/hm2 of Tiaohuahao was prayed with 600kg/hm2 of water respec-tively when the yonng panicles differentiation of MS line were in thextage seven and eight.The results were as fol-lows. Huaxinling and Tiaohuahao could increase the fore ncon blooming percentage,stigrna extertion,facililationof cross pollination,the yield of hybrid rice seed preduction distintly.
