土壤中一切复杂的生物化学过程都是在酶的作用下进行的。土壤酶的活性,反映了土壤中进行的各种生物化学过程的方向和强度。近年来,国内外许多学者对土壤酶作了许多研究。本文就杉木马尾松混交林以及杉木纯林土壤酶活性、土壤养分以及它们之间的关系作了研究,旨在探讨杉木经与马尾松伴生树种混交后,土壤酶活性和土壤养分的变化趋势以及它们同土壤肥力之间的关系。 All complex biochemical processes in the soil are carried out under the action of enzymes. Soil enzyme activity reflects the direction and intensity of various biochemical processes carried out in the soil. In recent years, many scholars at home and abroad made many studies on soil enzymes. In this paper, the soil enzyme activities, soil nutrients and the relationship between them were studied in a mixed forest of Pinus massoniana and Cunninghamia lanceolata, and the purpose of this study was to investigate the changes of soil enzyme activities and soil nutrients after mixed Chinese fir and Pinus massoniana coniferous species Their relationship to soil fertility.
