包膜缓释尿素对小白菜生理特性的影响
Effects of Coated Slow-release Urea on the Chinese Cabbage Physiological Characteristics
摘要
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, photosynthetic rate, transpiration rate? Total N. P and K, POD, SOD and CAT activity than those of CU,and other indicators were no less than those of CU. Different coating thickness had differences, and the type of 30% fly ash coated urea and 25%, 30% superfine phosphate powder coated urea were the best to Chinese cabbage.关键词
