摘要
文章阐述了树脂包衣尿素氮素释放原理,探讨了树脂包衣尿素在不同包衣率的情况下氮素养分的释放特征,以探明其释放规律。试验结果表明,在包衣材料相同的情况下,包衣率与树脂包衣尿素的氮释放速率成反比。
Releasing principle and coat technology for the coating urea were described. An inquiry is made into the characteristics of nitrogen nutrient released from the coating urea with various coating ratio,so as to ascertain the release pattern.The experimental results indicate that the coating ratio is in inverse proportion to the nutrient release rate from the coating urea with same coating polythene.
