腐植酸包裹型长效尿素肥效机理初步研究

Prelininary Studies about Fertilizing Value Mechanism of UHA

采用盆栽、试管培养及室内分析相结合的方法 ,研究了腐植酸包裹型尿素的氮素曲线释放特点以及渗透性包膜的抑制作用 ,进而提高该肥料利用率 。

Applying pot culture and tube culture combine with indoor analysis method.The results show that speciality of UHA nitrogen curve release and restraining effect of permeability envelope.Whereby it can upraise fertilizer use ratio and prolong fertilizing value duration.
