摘要

以粉煤灰和超微细磷矿粉为包膜材料

自制2种不同涂层厚度的包膜缓释尿素

研究2种不同膜材料缓释尿素对小白菜生理特性的影响。试验结果表明:与普通肥料相比

自制包膜尿素对小白菜生物量、光合蒸腾速率、全氮、全磷、全钾、POD、SOD、CAT活性均具有显著的改善作用

其他指标与普通肥料的相比差异不显著。不同涂层厚度之间差异显著

其中以30%粉煤灰包膜尿素及25%和30%的超微细磷矿粉包膜尿素对小白菜的效果最好。

Abstract

The experiment took the fly ash and superfine phosphate powder as the coated material

and made two kinds of coated slow-release urea(CSRU) with different coating thickness to study the effects on the growth of Chinese cabbage in field experiments.The experiment results showed that coated slow-release urea could significantly increase the plant biomass
