1988年,我们采取抛秧栽培方法稀植高繁水稻品系龙花83—079,共用种7.5千克,抛秧栽培3500平方米,折合亩用种1.43千克。秋季收获种子2580千克,折合亩产491.4千克,繁殖倍数344倍。我们的具体作法是: 用有孔地膜作育秧的隔离层。纸盘育苗,盘土用粘壤土与草炭混拌,比例为4:1。4月18～20日播种。因种子量少,难以撒匀,用煮熟稻谷作填充
In 1988, we adopted the method of throwing young seedlings to cultivate high flowering rice line Longhua 83-079, sharing 7.5 kg and throwing rice seedlings for cultivation of 3500 square meters, equivalent to 1.43 kg of mu. Autumn harvest seeds 2580 kg, equivalent to 491.4 kg per mu, breeding multiples of 344 times. Our concrete approach is to use an apertured film as a barrier to seedlings. Tray nursery, clay plate soil and peat mixing, the ratio of 4: 1. April 18 ~ 20 sowing. Due to the small amount of seeds, it is difficult to spread evenly, filling with cooked rice
