保水缓释肥在药用植物板蓝根上的试验研究

Experimental Study of a New Fertilizer of Retaining Water and Releasing Nutrients Slowly on the Medicinal Isatis Tinctoria

为了解决干旱作物农业地区养分不足和水资源短缺的问题,将保水剂与化学肥料按比例配合制得了既能吸水保水抗旱保墒,又具有缓释肥料功效的保水缓释肥。采用药用植物板蓝根为试验对象进行盆栽试验,对其保水效应及板蓝根生长状况进行观察分析,得出了保水缓释肥可以提高土壤的水分利用率、合理释放土壤有效养分、促生长作用明显的结论。

The study of a new fertilizer of retaining water and releasing nutrients slowly, which can help plants preserve water, is to solve lack of water and nutrients in arid agricultural regions. In the experiment, Isatis tinctoria, a medicinal plant, is studied, and its effect of preserving water and its growing situation is examined and analyzed. The conclusion is that the new type of fertilizers remarkably promotes Isatis tinctoria s growth.
