(一)“九二○”的性质伟大领袖毛主席教导我们:“大家明白,不论做什么事,不懂得那件事的情形,它的性质,它和它以外的事情的关联,就不知道那件事的规律,就不知道如何去做,就不能做好那件事。”要使“九二○”能够在农业增产上发挥作用,首先必须了解它的性质、作用以及与其他因素的关系。“九二○”是一种天然存在的化学物质,能够强烈刺激植物的生长,开始是从患水稻恶苗病的植株中分离获得的,后来发现在真菌及高等植物中也广泛存在。目前“九二○”是从水稻恶苗病菌的发酵产物中提取制备,纯的“九二○”为白色结晶状。“九二○”能够溶解于酒精、丙酮、醋酸乙酯或酸碱度pH6.2的磷酸缓冲液中,不能溶于煤油、氯仿、醚、苯等,难溶于水。工业生产
(1) Chairman Mao, the great leader of the “9/20” nature, teaches us: “Everyone understands that no matter what it does or does not know about it, its nature, its connection with other things beyond its knowledge, We must not know how to do it and we can not do it well. ”If we want to make the“ 920 ”play a role in increasing agricultural output, we must first understand its nature, role, and other factors. relationship. “920” is a naturally occurring chemical that strongly stimulates the growth of plants. It was isolated from plants suffering from Bakanae disease and later found to be widespread in fungi and higher plants. At present, “920” is prepared from the fermentation product of Fagus casthanum and pure “920” is white crystalline. “920” can dissolve in alcohol, acetone, ethyl acetate or phosphate buffer pH pH 6.2, can not be soluble in kerosene, chloroform, ether, benzene, insoluble in water.
