杉木火力楠混交林土壤肥力的研究

Study on the Fertilized Soil of Mixed Forests ofCunninghamia lanceolata-Michelia macclurei

本文通过6年生杉木火力楠混交林的土壤结构、水分性质、化学性质、土壤微生物和土壤酶活性的2年研究结果表明,杉木火力楠混交林具有良好的培肥土壤的功能,可在亚热带地区大面积推广,这对改善本区造林树种单调状况及开展地力衰退研究具有重大意义。

This paper deals with the two years' research work from 1987-1988 on the mixed forest of Cunninghamia lanceolata-Michelia macclurei(6yrs), in which soil structure, soil moisture properties, soil chemistry, soil microbe and soil enzyme activities were studied. The result showed that the mixed forest (3 Cunninghamia lanceolate:1 Michelia macclurei ) has better fertilized soil, so that it can be largely spread in subtopical areas, which has great significance in improving the forestation condition of monotonous species there and in carrying out studies of the declined fertility in that areas.
