汾阳县见喜乡近几年来种植高粱面积1万亩左右,主要品种为晋杂4号,品质好,产量高,深受群众欢迎。但是1985年有不少地块出现了枝穗(高粱上部歧生出来的穗子),少者每株1—2穗,多者每株4—5穗,严重地影响了产量。根据科技人员在见喜乡北庄村调查,该村1985年种植高粱613亩,其中枝穗211亩,占高粱总面积的34.3％。我们具体调查了相邻的两块高粱地,品种(晋杂4号)相同而施肥时间不同,结果枝穗多少、产量高低也不同。一块由于三肥一齐施,促进了壮苗,增强抗逆性,提高小花结实率,所以到天旱时已形成了正常的主穗,后期很少有枝穗,亩产高粱400公斤。另一块是苗期追肥,因前期天旱时没有发挥出肥
Seeing Happy Township in Fenyang County In recent years, planting about 10,000 acres of sorghum area, the main varieties Jin 4, good quality, high yield, welcomed by the masses. However, in 1985 there were lots of spikes (spikes scattered in the upper part of sorghum) in many plots, with 1-2 spikes per plant and more plants with 4-5 spikes per plant, which seriously affected the yield. According to a survey conducted by scientific and technical personnel in Beizhuang Village, Jixi Township, the village planted 613 hectares of sorghum in 1985, of which 211 were branches, accounting for 34.3% of the total area of the sorghum. We specifically investigated the adjacent two sorghum, the same varieties (Jin hybrid No. 4) and fertilization time is different, the results of how many spike, the yield is also different. As a result of three fertilizer together, to promote strong seedlings, enhance resistance, and improve the rate of floret, so the drought has formed a normal main spike, late few branches, yielding 400 kg of sorghum per mu. Another is the top seedling fertilizer, due to the previous drought did not play a fat
