用“倒种春”的栽培方法,可以高速度繁育早稻良种、改善其种性,从而提高早稻产量。黄岩路桥良种繁育场去年用陆财号品种试验的结果表明:“倒种春”种子比一般种子长成的稻株平均有效分蘖增加12.1%,瘪谷减少4.15%,千粒重提高1.8%,亩产燥谷731斤,增产18.2%。同时,还可以节省晚稻秧田面积7—8%,提高了复种指数,增加总产量。黄岩县的“倒种春”栽培,从1955年农民专家杨匡保同志试种开始,面积逐年扩大。1959年已从1958年的3,000多亩增加到8,800多亩。几年来关于水稻
With the “inverted spring” cultivation methods, high-speed breeding of early rice varieties to improve their species, thereby increasing the yield of early rice. Last year, the trial of landrace breeds in Huangyan Luqiao showed that the average effective tiller length increased by 12.1%, reduced by 4.15% and grain weight increased by 1.8% Dry Valley 731 pounds, an increase of 18.2%. At the same time, you can also save late rice seedling area of 7-8%, increased cropping index, increase total output. The cultivation of “inverted spring” in Huangyan County started from the trial of peasant expert Yang Kuangbao in 1955 and has been expanding year by year. It increased from 3,000 mu in 1958 to 8,800 mu in 1959. Over the years about rice
