我们从1979年起,对油菜秋发高产栽培进行了系统研究。1979—1981年在原广济县(现武穴市)对30块(每年10块)油菜高产试验田进行观察调查,发现亩产200公斤以上的冬前(12月底)植株(每亩8000株左右)绿叶有12—13片,叶面积指数2.5—3.0,植株干重200公斤以上,我们将冬前这种长相的油菜称为“秋发”生长型(《湖北农业科学》1982年12期)。从1979—1989年,我们先后在湖北广济、四川绵竹和武昌本所,采取小区试验(计48项次)与大田试验示范相结合的方法,并对油菜秋发高产技术进行了试验与调查:1980年在
Since 1979, we conducted a systematic study on the rapeseed high yielding cultivation. 1979-1981 In Guangji County (now Wuxue City), 30 high-yielding experimental fields of rapeseed (10 per year) were observed and investigated. It was found that before the end of winter (at the end of December) more than 200 kilograms per mu (about 8000 plants per mu) 12-13 green leaves, leaf area index 2.5-3.0, plant dry weight of 200 kg or more, we will be the winter before the appearance of this rape called “autumn hair” growth type (“Hubei Agricultural Sciences” 1982 the 12 period). From 1979 to 1989, we conducted experiments and surveys on the high yield rapeseed culm production techniques in Guangji, Hubei, Mianzhu, Sichuan and Wuchang, using the combination of plot experiment (counting 48 times) and field experiment and demonstration 1980
