为了加速油菜新品种的选育进程,缩短育种年限,一九七六年五月,我们到资源县车田公社黄保冲大队笋山头十三队,进行油菜杂交后代的繁殖试验。从试验的初步结果看,夏繁是有成效的。笋山头,地处越城岭山脉,海拔974米,无霜期短,夏天气温较低,雨水偏少,但雾多,湿度较大。每年只种植单季稻。试验经过试验地为海拔950米山麓中的中造田,砂壤土,肥力中等,排灌方便。经两犁一耙

In order to speed up the breeding process of new varieties of rapeseed and to shorten the breeding period, in May, 1976, we went to the Thirteenth Team of Bamboo Shoots at Huangbaochong Brigade, Zhubian Commune, Zhuanyuan County for breeding experiments. From the preliminary results of the trial, Xia Fan is effective. Bamboo Hill, is located in the Yuechengling Mountains, 974 meters above sea level, frost-free period is short, the summer temperature is low, less rain, but more fog, humidity. Only grow single-crop rice each year. Experimental test for the 950 meters above sea level in the foothills of the field, sandy loam, medium fertility, irrigation and drainage convenience.
