1) soil reduction process
土壤还原
3) Soil oxidoreductase
土壤氧化还原酶
1.
Soil oxidoreductase is a group of enzymes catalyzing many important soil biochemical reactions and concerning with the transformation of soil organic matter,formation of humic substance,and dynamics of soil fertility.
土壤氧化还原酶是存在于土壤中的一种重要酶类,参与土壤中为数众多的重要生物化学反应,与土壤中有机物质的转化、腐殖质的形成以及土壤肥力变化密切相关。
4) denitrifying enzyme
土壤反硝化还原酶活性
1.
The correlations between physical, chemical and biological properties and denitrifying enzyme activity, soil N2O flux were studied by field experiments during the course of wheat growing stages in both arid and semi-arid areas.
结果表明,在冬小麦生育期内,0—5cm土层土壤硝酸还原酶活性与相应土层土壤亚硝酸还原酶活性呈显著正相关,0—5cm,5—10cm土层土壤的温度与相应土层土壤硝酸还原酶活性呈显著负相关,土壤硝态氮含量和pH与土壤反硝化还原酶活性的相关性因土壤的不同土层而有差异;0—5cm,5—10cm土层土壤含水量,0—5cm,10—20cm土层土壤脲酶活性,5—10cm有机碳含量,硝酸还原酶活性与土壤中N2O排放通量呈显著正相关;5—10cm土层土壤温度、pH和10—20cm土层土壤磷酸酶活性、pH与之呈显著负相关。
5) soil Eh
土壤氧化还原电位
1.
A pot culture experiment of rice in greenhouse was carried out to investigate the diurnal variations of CH 4 fluxes,soil temperatures and soil Eh during rice growing period with different treatments applied in the former winter cropping season.
种稻盆钵土壤甲烷排放通量昼夜变化主要受０～１０ｃｍ深土壤温度的影响，而与土壤氧化还原电位无关。
