一九七七年早造我们学习班种植不育系繁殖田33.27亩,平均亩产112.6斤,其中广陆银A8.73亩,亩产151.2斤,最高的广陆银A1.63亩,亩产177.8斤。杂交水稻制种配制了26个组合,共52.24亩,平均亩产82.5斤。产量最高的是汕优二号,2.18亩,亩产177.8斤。在实践中,大家体会到繁殖制种最重要的环节,可归纳成四句话:即“种子纯度要保证,季节安排要适宜,花期相遇是关键,提高产量挖潜力”。
In early 1977, we created 33.27 mu of sterile plant propagation fields in our study class, with an average yield of 112.6 kg per mu. Among them, Guang Lu Yin A has a yield of 151.7 kg mu, and the highest Guangluan A1.63 mu Produce 177.8 pounds. Hybrid rice seed preparation of 26 combinations, a total of 52.24 acres, an average yield of 82.5 kg. The highest yield is Shanyou 2, 2.18 mu, 177.8 kg per mu. In practice, we all realize that the most important part of breeding and seed production can be summarized into four sentences: “The purity of seeds must be guaranteed, seasonal arrangements should be appropriate, and flowering is the key to meeting the potential of increasing output.”
