腐植酸钠是一种良好的作物生长刺激剂。根据我区1975—1976两年的试验示范结果,用于小麦、玉米、谷子浸种等,较对照增产5—30%;在小麦花期喷施,较不喷的增产7.2—15.6%。但也有少数试验示范增产不显著,甚至减产。据了解,主要是水质不良,施用不当引起的。为此,提出以下意见,供各地参考。一、施用软水。不论是浸种还是喷洒,稀释腐植酸钠必须用软水。如用硬水,须先进行软化。软化方法是:(1)将冷水煮沸,用澄清的冷开水配置药液。(2)在硬水中加适量
Sodium humate is a good crop growth stimulant. According to the pilot demonstration results from 1975 to 1976 in our district, it is used for soaking seeds of wheat, corn and millet, and the yield is increased by 5-30% compared with the control. In spraying at the flowering stage of wheat, the yield is increased by 7.2-15.6%. However, there are also a few experimental demonstrations that the yield increase is not significant or even reduced. It is understood that the main water quality is poor, caused by improper application. To this end, the following comments are made for reference. First, the application of soft water. Whether it is soaked or sprayed, dilute sodium humate must use soft water. If hard water, must be softened. Softening method is: (1) the cold water to boil, clarify the cold water configuration liquid. (2) add appropriate amount in hard water
