新氮酮对水溶肥料润湿性能的影响

Effect of New Azone on Wettability of Water-Soluble Fertilizers

利用直接测量润湿面积和最大气泡压力法测定表面张力,研究不同浓度的新氮酮对5种水溶肥料润湿性能的影响。试验结果表明:不同类型水溶肥料喷施液中新氮酮的适宜添加量略有差别,其中大、中量元素水溶肥料中新氮酮的适宜添加量约为体积分数0.04%,微量元素、含氨基酸和含腐殖酸水溶肥料中新氮酮的适宜添加量约为体积分数0.06%,此时润湿面积平均增大2倍左右,润湿效果良好。

By direct measurement of wetted area and using maximum bubble pressure method to determine surface tension, the effect of new azone concentrations on wettability of five water-soluble fertilizers is researched. Experimental results show that the suitable addition levels of new azone slightly differ with different water-soluble fertilizers, among which, for water-soluble fertilizers with macro and medium elements the suitable addition level is about 0.04% （volume fraction）, and for trace element water-soluble fertilizers, water-soluble fertilizers containing amino acid and humic acid, the suitable addition level is about 0.06% （volume fraction）, under this condition, the wetted area increases about 2 times on average, wetting effect is good.
