实验结果表明：涂层中松香的含量及包膜量(膜厚)是影响包膜尿素养份释放速率的主要因素。

Experimental results indicate that the rosin content in the coating and film thickness are the main factors influencing the nutrient release rate of the encapsulated urea.

分析了松香与石蜡的配比、涂层量对包膜尿素养分释放速率的影响。

Also, the influences of the ratio of rosin to paraffin wax in coating, and of coating weight on the nutrient release rate were discussed.
