在毛主席革命路线指引下,在“农业学大寨”群众运动中,我省杂交高粱近几年发展很快,据统计,1972年杂交高粱种植面积已达总面积的35.4％,而在文化大革命前尚处试验阶段。实践证明,杂交高粱适应性广,抗逆力强,增产潜力大,一般比普通品种增产30％-50％,有的甚至成倍增产。贫下中农称杂交高粱是超“纲要”品种,迫切要求扩大种植。但杂交高粱在推广中,也出现一些缺点,如小花败育、杂种一代小花不实、着壳率高等。如何采取措施,逐步克服这些缺点,是目前推广杂交高粱中值得研究的问 Under the guidance of Chairman Mao’s revolutionary line, in the mass movement of “learning from agriculture in Dazhai”, hybrid sorghum in our province has developed rapidly in recent years. According to statistics, the area planted with hybrid sorghum reached 35.4% of the total area in 1972, Before the revolution still in the pilot phase. Practice has proved that hybrid sorghum wide adaptability, strong anti-adversity, yield potential, generally 30% -50% increase over ordinary varieties, and some even doubled production. Poor middle peasants claim hybrid sorghum is super “outline” varieties, an urgent requirement to expand planting. However, in the promotion of hybrid sorghum, there are also some shortcomings, such as abortion, hybrid generation floret, shell rate and higher. How to take measures to gradually overcome these shortcomings is the promotion of hybrid sorghum worth the study
