七十年代初期,我所曾研究油菜大壮苗移栽技术和越冬单株绿叶数、最大叶宽等高产形态指标,在生产上应用效果较好。1976—1983年,我们与武汉市洪山区协作,共同培育出亩产400斤以上的有12块田,其中免锄4块;500斤以上的有7块田,其中免锄5块。与此同时,还出现亩产200—300斤的丰产片,带动了当地大面积油菜生产。在高产经验中,我们还对油菜绿色群体数据进行了相关性分析,发现在小雪节苗期和苔期的群体叶面积与产量高度相关;而叶面积增长
In the early seventies, I have studied the transplanting technology of big strong seedlings of rapeseed and the number of green leaves per plant in the wintering, the maximum leaf width and other high yield morphological indicators, which have good application effects in production. In 1976-1983, we cooperated with Hongshan District in Wuhan City to jointly cultivate 12 fields of more than 400 kg per mu, of which 4 were exempted from hoeing and 7 fields were over 500 kg, of which 5 were exempted from hoeing. At the same time, there have also been high yields of 200-300 kg of mu per mu, leading to the large area of rapeseed production in the area. In high-yielding experience, we also conducted a correlation analysis of green rapeseed population data and found that the leaf area of the population in the seedling stage and the moss stage is highly correlated with the yield; and the increase of the leaf area
