| 摘 要： | 为探明粉煤灰与超细磷矿粉作为包膜材料的缓释效果,以粉煤灰和超微细磷矿粉为包膜材料,自制两种不同涂层厚度的包膜缓释尿素,在大田实验条件下,以普通尿素、树脂包膜尿素和硫包膜尿素为对照,研究了两种不同膜材料缓释尿素对土壤养分特性的影响。结果表明:自制包膜尿素比普通尿素更能改善土壤的持续供氮能力,提高土壤脲酶活性,30%粉煤灰包膜尿素及25%和30%的超微细磷矿粉包膜尿素缓释效果最好;与树脂包膜和硫包膜尿素相比,自制包膜尿素可提高小白菜生长前期土壤中的养分含量。

| Abstract: | In order to study the slow release effect of fly ash and superfine phosphorite powder as fertilizer coating material,this 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 their effects to soil nutrient characteristics in field experiments compared with common urea resin coated urea and sulphur coated urea.The results showed that CSRU made by ourselves could increase the content of alkalized N in soil and improve the soil urease activity compared with common urea(CU).The types of 30% fly ash coated urea and 25%,30% superfine phosphate powder coated urea showed the best for Chinese cabbage.Compared with resin coated and sulfur coated urea,homemade coated urea could improve soil nutrient characteristics in the early growth of Chinese Cabbage. |
