1977年秋季以来,我们在湖北广济县石佛寺公社陈德云大队进行水田三熟油菜高产栽培技术的总结研究,每年设置高产试验(10丘以上)和小区试验,定期观察取样,调查油菜冬发与高产的关系,主要生育时期形态长相、营养生理特点及其主要技术措施。1979年秋季起,组织了黄冈地区油菜高产协作网,1980年秋季又组织了长江中游油菜高产技术协作区,大力示范推广广济县油菜高产技术经验,均取得很好效果,获得了1980年国家技术改进一等奖。现将1977—1981年的有关试验资料总结分析如下。
Since the fall of 1977, we conducted a summary study on the high-yielding cultivation techniques of rapeseed in paddy field with the help of Chen Deyun Brigade of Shifushi Temple Commune, Guangji County, Hubei Province. High yield test (more than 10 mounds) and plot test were set every year. Samples were regularly observed, The relationship between high yield, the main growth period morphological appearance, nutrition and physiological characteristics and its main technical measures. Since the fall of 1979, the high-yield co-operative network of rapeseed in Huanggang has been organized. In the autumn of 1980, a collaborative area for high-yield rapeseed production in the middle reaches of the Yangtze River has been organized to demonstrate and promote the high-yielding rapeseed technology experience in Guangji County. All achieved good results in 1980. First prize for technical improvement. Now 1977-1981 the relevant experimental data are summarized as follows.
