摘要
在简述近年来腐植酸在农业的研究进展和腐植酸肥料的制备原理的基础上,总结了腐植酸绿色低碳肥料田间试验的研究进展。介绍了腐植酸在提高化肥利用率即减少化肥养分损失及促进养分吸收方面有很大的改善,不同类型腐植酸肥料的合理施用有利于提高作物产量和品质,如腐植酸磷肥处理玉米籽粒产量增加4.5%~13.6%;腐植酸铵的添加可使油葵增产23.98%;腐植酸复混肥的施用使番茄平均增产16.4%,黄瓜增产10.9%;活性腐植酸复合肥添加可使甘薯可溶性糖含量增加20.45%,可溶性蛋白含量增加41.86%,因此经济效益也得到提高。
On the basis of briefly describing the research progress of humic acid in agriculture in recent years and the preparation principle of humic acid fertilizer, the research progress of field trials of humic acid green low-carbon fertilizer is summarized.Introduced that humic acid has greatly improved the utilization rate of chemical fertilizers, that is, reducing the loss of fertilizer nutrients and promoting the absorption of nutrients.The rational application of different types of humic acid fertilizers is conducive to improving crop yield and quality, for example, humic acid phosphate fertilizer treatment increases corn grain yield by 4.5% to 13.6%;the addition of humate ammonium can increase oil sunflower yield by 23.98%;the application of humic acid compound fertilizer increased tomato yield by 16.4% and cucumber yield by 10.9%;the addition of active humic acid compound fertilizer increased the soluble sugar content of sweet potato by 20.45% and the soluble protein content by 41.86%,so the economic benefit was also improved.
