Three investigations were carried out. The first determined the relationships between dehydrogenase acitivty throughout the course of composting wheat straw and the changes in both organic carbon and total nitrogen. The second investigation tested the validity of the first investigation results. The third dealt with the effect of the degree of ripening of a compost, expressed by age and C/N ratio, on its dehydrogenase activity, and production of CO2. The results revealed continual decreases in the organic carbon, coincident with increases in total N and dehydrogenase activity. Noticeable chemical and biological changes occurred in the first and third month. Levels of dehydrogenase were highest in rice straw and lowest in cotton stalk compost, while the wheat straw compost occupied an intermediate position. Aging of the compost resulted in increases in the dehydrogenase figures and decreases in the amounts of CO2 produced.
进行了三项调查。第一项调查确定了小麦秸秆堆肥过程中脱氢酶活性与有机碳和总氮变化之间的关系。第二项调查检验了第一项调查结果的有效性。第三项调查研究了用年龄和碳氮比表示的堆肥成熟度对其脱氢酶活性和二氧化碳产生的影响。结果显示有机碳持续减少，同时总氮和脱氢酶活性增加。在第一个月和第三个月发生了明显的化学和生物变化。脱氢酶水平在稻草堆肥中最高，在棉秸秆堆肥中最低，而小麦秸秆堆肥处于中间位置。堆肥老化导致脱氢酶数值增加，二氧化碳产生量减少。
