摘要:

涂层尿素的研究始于1987年,概述了30年来涂层尿素研发应用的3个阶段。新一代涂层尿素所用膜材料更安全,膜结构更稳定,营养元素更有效,氮素利用率也更高。近2年的试验研究表明,与普通尿素相比,涂层尿素的氮素利用率可提高11.1%,多地多种作物试验统计平均增产13.84%,可提高樱桃、苹果、西瓜等经济类作物的糖分、维生素C和钙含量,土壤中碱解氮及DATA-Fe、Zn含量增加。

Abstract:

The study of coated urea began in 1987, and three stages of research, development and application of coated urea in 30 years are summarized. The membrane materials used for the new generation of coated urea are much safer, membrane structure is more stable, nutrient elements are more effective, and nitrogen utilization rate is much higher. Nearly two years experimental research shows that the nitrogen utilization rate of coated urea can increase by 11.1% compared with common urea, and the average yield of multivariate crop tests increase by 13.84%. It can also improve the sugar, vitamin C and calcium content of cherry, apple, watermelon and other economic crops, and alkali-hydrolysable nitrogen, DATA-Fe and Zn content in the soil increase.
