腐植酸铵与除草剂配伍的效应研究

Positive Synergy Effect of Ammonium Humate on Herbicide

为探索研究腐植酸铵对除草剂的增效作用,笔者进行了田间试验。试验结果表明:腐植酸铵与除草剂草甘膦配伍,可提高除草药效10%～15%,药效过程可提前2～5 d;腐植酸铵与烟嘧磺隆,2,4-D丁酯配伍不仅可提高药效20%,而且还能促进玉米生长,增加其抗逆性,腐植酸的抗蒸腾性,还可增加叶面喷药效率,这对于促进生态农业发展和绿色环保有广阔前景。

In order to explore the synergy effect of ammonium humate on herbicide, the experiment was carried out in the field. The results showed that the weeding efficiency could be improved by 10 % - 15 % and the pharmacodynamic process could be shortened 2 - 5 days through the combined use of ammonium humatc and glyphosate. Compatibility use of ammonium humate, nicosulfuron and 2,4-D butyl acetate could not only improve efficacy by 20 % , but also could improve corn growth, enhance their stress resistance, restrain the evaporation of humic acid , and improve the spraying efficiency of liquid on the surface of leaves. This process would have broad prospects in the aspects of promoting the development of eco-agriculture and green environmental protection.
