峰火大队1972年有500亩左右早稻发生“噤害”。其表现是:秧苗返青慢,发棵少,甚至不发棵;禾苗心叶抽出三,四天后,叶尖就开始发黄变红,并出现铁锈色小斑点,逐渐扩展至全叶,远看似火烧过一样;白根少,黄根、黑根多,根腐发臭。田土稀汤胃气泡,秧苗扎根不稳。“噤害”多出现在山冲冷浸田、湖区深泥田和前作绿肥田。 为了解决这个问题,大队党支部组织干部,老农,技术员深入田间,分析原因,研究解决办法。大家认为:水稻发噤的原因是由于田土冷浸,土温、水温低,不利禾苗返青发棵;绿肥腐烂过程中发生有毒物质,锈水
Peak fire brigade in 1972 about 500 acres of early rice occurred “harm.” Its performance is: slow green seedlings, hair less, do not even send trees; seedling leaves heart out three or four days later, the tip began to turn yellow and red rust spots and small spots gradually extended to the whole leaf, seems far fire The same; white root less, yellow root, black root more root rot. Tien soil thin stomach bubble, seedling instability. “Harm” appear in the mountain cold soaked fields, deep mud fields and former green lake fertilizer fields. To solve this problem, the brigade party branches organized cadres, veterans and technicians into the field, analyzed the causes and studied solutions. Everybody thinks: The reason of rice is due to field cold soaking, soil temperature, low water temperature, unfavorable grasses turn green trees; green fertilizer decay occurs in the process of toxic substances, rust water
