1977年秋季以来,我们在广济县石佛寺公社陈德云大队与当地协作,总结研究水田三熟油菜高产栽培技术。1979年陈德云大队1块中熟品种甘油5号(下同)1.16亩,亩产400.3斤。1980年陈德云、石牛、宋煜大队的5块田,面积共13.5亩,平均亩产426.7斤。1981年太平公社梅岩六队1块1.54亩,亩产404.9斤。从三年来7块高产田的调查资料看,甘蓝型中熟品种亩产400斤以上要靠秋发才有把握。所谓秋收,就是指油菜在秋末(按候温划分,该地区9—11月为秋季)达到9—10片绿叶,叶面积系数达到1.2—1.5的发棵水平,即提前一个月达到冬发标准。下面就三年来的研究进行总结分析。
Since the autumn of 1977, we collaborated with the local Chen Deyun Brigade in the Shifushi Temple Commune in Guangji County to summarize the high-yielding cultivation techniques of the paddy field SanRou rape. In 1979, Chen Deyun brigade 1 medium-maturing variety glycerol 5 (the same below) 1.16 mu, 400.3 kg per mu. In 1980, Chen Deyun, Shi Niu, and Song Yu’s five fields numbered 13.5 hectares in area, yielding an average of 426.7 kilograms per mu. In 1981 Taiping commune plum rock six teams a 1.54 acres, 404.9 kg per mu. From the survey data of seven high-yield fields in the past three years, it is only necessary to rely on the autumn hair for more than 400 pounds of middle-maturing varieties of cabbage. The so-called autumn harvest, refers to the rape in the late autumn (according to warm temperature division, the region 9-11 months for the autumn) to reach 9-10 green leaves, the leaf area coefficient reached 1.2-1.5 hairy level, that is, one month in advance to reach winter standard . The following three years of research to summarize the analysis.
