为了比较系统地认识油菜生育规律和总结高产经验,同时了解生产动态和培养农村技术骨干,从1973年秋播起,我们与郊区油菜高产单位组成了油菜高产联合试验,统一观察测定的项目、方法和时间,在各主要生育阶段进行了观察和交流。四年来,除1977年因特殊气候影响以外,一些单位的试验田都稳产在300斤以上,10—13个联系点的平均产量1974年为355斤,1975年为254斤,1976年为263斤,1977年为225斤;分别比全市平均产量高21.0—46.6%。现就综合试验的结果,谈几点看法:
In order to systematically understand the law of rapeseed growth and summarize the high yielding experience, understand the production dynamics and cultivate the backbone of rural technology at the same time, we planted high yield joint trials with rapeseed high-yielding units in the suburbs from the autumn of 1973 to unite the observed projects, methods and Time, observed and exchanged in all major stages of fertility. In the past four years, with the exception of the special climate in 1977, the experimental fields in some units have been steadily producing more than 300 kilograms. The average yield of 10-13 contact points was 355 kilograms in 1974, 254 kilograms in 1975 and 263 kilograms in 1976, 225 pounds in 1977; respectively, 21.0-46.6% higher than the average output of the city. Now on the results of a comprehensive test, talk about the views:
