常見例句雙語例句The heritability of N content in grain and leaf and N utilization efficiency were high.子粒、葉片含氮量和氮利用效率的遺傳率相對較高。The results of genetic cluster analysis of N utilization efficiency showed that 137 wheat parents could be divided into three types.小麥親本氮素利用效率的遺傳聚類分析，將137個小麥親本分為三類。Under different application rates of W, N, K and M, the N utilization efficiency was significantly increased with optimum timing of watering and fertilization.水肥施用分配相對于不同水、化肥（N、K ）、有機肥量的選擇，可以大大地提高肥料N利用率； 返回 n utilization efficiency
