土壤微生物与林木生长关系初探

PRELIMINARY RESEARCH ON THE RELATIONSHIP OF EDAPHON AND TREES GROWTH

本文采用常规土壤微生物分离培养和计数方法,初步探讨了不同林地、不同土质中微生物种群的分布和数量与林木生长的关系。研究表明:土壤微生物分布愈广,数量愈多,种群愈复杂,愈有利于改良土壤的理化性质,提高土壤肥力,促进林木的速生丰产。

The relationship of the number and distribution of edaphon that growed in different texture soils on different sites and trees growth was researched preliminaryly on by the common method of edaphon which were isolated to eulture and numbered. If there were more numbers, wider disuibution and more comolex strueter of phytoedaphon, trees there hed faster growth and higher yield because the chemical-physical properties of soil were improved to make soil fertility power.
