nutrient rate

基本解释

The nutrient release rate and release longevity could be estimated or evaluated in short period of time by using fast extraction measurement method.
快速测定方法可以在较短时间内，推测和评价控释肥料的养分释放速率的快慢及释放期的长短。
The fast extraction measurement of nutrient release rate of coated controlled-release fertilizer was the key for quality determination and criterion establishment.
快速测定方法可以在较短时间内，推测和评价控释肥料的养分释放速率的快慢及释放期的长短。
The result showed: Among all examined fertilizers, the nutrient release rate of urea was the highest and that of controlled release nitrogen fertilizer was the lowest.
研究结果表明：控释氮肥养分释放速率最低、肥效最长，与尿素相比可改善运动场草坪的外观品质；
