- 生物固NBiological nitrogen fixation
- 摘要豆科及非豆科固氮樹(shù)種是重要的生物固N資源。Nitrogen fixation trees of Leguminosae and non-Leguminosae are important biological nitrogen fixation resources.
- 5(nt)和6.1(nts)kg/hm2,生物固N量占總N輸入量的百分比為14.6(t)、21.5(ts)、14.9(nt)和12.9(nts);A soil NO_3-N concentration of 40 kgN/hm~2 was thought to be the critical value above which BNF activity was reduced. Soybean obtained its N requirements from both soil N and BNF. When there was no BNF activity recorded,N was supplied wholly by soil N,which led to soil N depletion and soil N scarcity.
