我们在公社党委的直接领导下,在种子场的大力支持下,去年第一次搞了杂交水稻制种工作,取得了一定的成绩。制种田2.09亩,组合均为二九南1号A×IR24,实收杂种262斤,平均亩产125.4斤,其中,行比1∶4的1.01亩,折亩产117.8斤;行比1∶5的0.62亩,折亩产160.5斤;行比2∶6的0.46亩,折亩产94.5斤。现将杂交水稻制种技术简述如下: (一)掌握好父母本的播种期:花期相遇
Under the direct leadership of the commune party committees and with the vigorous support of the seed field, we made the first hybrid rice seed production work last year and achieved some success. 2.09 acres of farming system, the combination are two nine South 1 A × IR24, the actual harvest of 262 pounds, average yield 125.4 kg, of which 1.01 mu than the row of 1: 1, fold mu yield 117.8 pounds; row ratio of 1: 5 of 0.62 acres, fold yield 160.5 pounds; line ratio of 2:46 of 0.46 acres, yield 94.5 kg mu. Hybrid rice seed production technology now briefly described as follows: (a) grasp the parental sowing date: flowering meet
