在“5406”抗生菌的代谢产物中,含有多种不同成分的刺激物质,有类似激动素和生长素的作用.本试验是在水稻穗期喷施“5406”,以研究对水稻产量的影响及其生理效应.材料和方法(一)“5406”菌粉浸出液(简称Ⅰ液):采用中国农科院原子能所提供的“506”菌株进行三级固体发酵.斜面培养基高氏1号,二级母剂培养基大米饭加2%碳酸钙,三级培养基:10%碎米、10%麦麸、5%菜饼粉、5%钙镁磷肥、70%泥土,pH8.5～9(消毒前),在28～32℃培养7天后,在40～50℃烘干.菌粉先用少量清水搅成糊状,按比例加足水量,浸泡12～24小时,将沉淀物充分搓洗,过滤去渣待用.
In the metabolites of “5406” antibiotics, there are many different stimulating substances that have similar functions as kinetin and auxin.In this experiment, “5406” was sprayed on paddy to study the effect on rice yield And their physiological effects.Material and methods (I) “5406” powder leachate (referred to as Ⅰ liquid): The “506” strains provided by the Chinese Academy of Agricultural Sciences atomic energy to carry out three solid fermentation.Calcium medium No. 1, Secondary mother medium rice plus 2% calcium carbonate, tertiary culture medium: 10% broken rice, 10% wheat bran, 5% vegetable powder, 5% calcium magnesium phosphate fertilizer, 70% soil, pH8.5 ~ 9 (Before disinfection) and cultivate at 28 ~ 32 ℃ for 7 days, then dry at 40 ~ 50 ℃, use small amount of water to mix the paste, then add water in proportion and soak for 12 to 24 hours, fully scrub the sediment , Filtered residue to be used.
