肥料氮
The maximum nitrification ratio of fertilizer N in soil is up to 20%-42%, according to the soil fertility and rate of fertilizer N applied.
氮肥中N在土壤中的净硝化率最高达42%,因土壤肥力和施N量不同而异。
There was very little fertilizer N residue left, most of which entered the organo-mineral complex, while a part of the soil N was activated.
化肥氮残留很少,大部分进入土壤有机无机复合体中,而部分土壤氮被活化。
The results showed that the efficiency of fertilizer N used by wheat increased and a higher percentage of N absorbed was translocated into grain under the interplanting condition.
结果表明,麦棉套作条件下,小麦对肥料氮的吸收和利用率显著提高,且所吸收的氮素较多地分配到籽粒中。
