杂交高粱的再生,就是在杂交高粱第一季直播收获后,将高粱露地茎杆割掉,利用留下的老蔸,重新生出分茢再收获一季。近年来广东省、浙江金华地区和安徽涡阳县等地试种都获得较好的收成。 广东省农作物杂种优势利用研究协作组各协作点的结果如下:①英德县沙口公社冬爪铺大队1971年第一季杂交高粱178亩,平均亩产410斤。再生116.5亩(第一季连片的93亩全部再生),每亩田间管理平均花工10个,在几次台风的袭击后仍亩产300多斤,两季合计亩产
Hybrid sorghum regeneration, that is, the first season after hybrid sorghum harvest live, the sorghum exposed stem cut off, use the old leaves left to regenerate the sub-茢 re-harvest season. In recent years, Guangdong Province, Jinhua in Zhejiang Province and Anhui Guoyang County and other places have been better seed yields. The results of the collaboration points of the Research Group on Heterosis Utilization of Crops in Guangdong Province are as follows: (1) 178 mu of sorghum were cross-harvested in the first quarter of 1971 in Shakugong Commune of Shakou Commune of Yingde County, with an average yield of 410 kg per mu. Regeneration of 116.5 acres (contiguous in the first quarter contiguous 93 acres of regeneration), per mu field management, the average flower 10, after several typhoons still mu yield 300 kilos, the total yield per mu
