摘要
通过对生产腐植酸生物液体肥(棚室蔬菜专用)的原料进行腐植酸含量、生物活性、交换容量等综合指标的检测分析,来确定用于该液体肥料生产的最佳原料,进而生产出腐植酸生物液体肥(棚室蔬菜专用)并应用于棚室栽培蔬菜黄瓜、番茄、豆角上,以检验其肥效,同时对施用该液体肥料前后栽培地的土壤进行了理化性质变化情况的对比检测。试验结果表明:腐植酸生物液体肥既可以明显地提高黄瓜、番茄、豆角的品质,又具有一定的增产作用,可以使黄瓜增产9.7%～11.9%、番茄增产15.5%～16.3%、豆角增产8.6%～11.3%,同时可以有效地改善栽培地的土壤微生态环境。因此,腐植酸生物液体肥是生产无公害、绿色蔬菜及其他农作物的有效肥料之一。
According to the analysis of the content of HA, microorganism activity and exchange capacity of the raw material to produce the HA microorganism liquid fertilizer (the vegetable specific-fertilizer in the greenhouse), the best raw material produced for the liquid fertilizer was made certain. The results showed that application of this fertilizer could improve the yield and quality of the cucumber, tomato, and the bean clearly. In contrast to the control, the yield of cucumber was increased by 9.7%～11.9%, tomato by 15.5%～16.3%, and the bean by 8.6%～11.3%. In the meantime, the application of this fertilizer could improve the micro-ecosystem of soil. Therefore, the HA microorganism liquid fertilizer is a promising fertilizer suitable for green vegetable and other farm crops.
