【摘要】 探讨了硫包膜尿素(SCU)在不同包膜比例以及使用添加剂的情况下氮素养份的释放特征,以探明其 释放规律。试验结果表明,未使用添加剂的SCU初始释放率高于使用添加剂的SCU,而膜重所占比例与SCU的 养份释放速率成反比。更多还原

【Abstract】 An inquiry is made into the characteristics of nitrogen nutrient released from SCU with various coating ratio and the use additives, so as to ascertain the release pattern. The experimental results indicate that the initial release rate from SCU without additives is higher than that from SCU with additives, and the coating ratio is in inverse proportion to the nutrient release rate from SCU.更多还原
