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.
快速測定方法可以在較短時間內，推測和評價控釋肥料的養分釋放速率的快慢及釋放期的長短。
The fast extraction measurement of nutrient release rate of coated controlled-release fertilizer was the key for quality determination and criterion establishment.
快速測定方法可以在較短時間內，推測和評價控釋肥料的養分釋放速率的快慢及釋放期的長短。
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.
研究結果表明：控釋氮肥養分釋放速率最低、肥傚最長，與尿素相比可改善運動場草坪的外觀品質；
