前言森林土壤中的落枝落叶、动物遗体的分解和消失,主要是靠土壤生物的活动。因而,在林地施用绿肥,土壤生物的活动情况当然就成了问题的重点。森林土壤生物相,往往由于微小的环境差异而发生微妙的变化,并影响其分解落枝落叶的能力。在林地施用绿肥,则有绿肥性质、施用量、时期、次数、施用地土壤条件及施用后的气象条件等众多因子纠缠在一起的复杂情况。下面介绍的事例,对其给予土壤生物以复杂影响的问题来说,也只不过是管中窥豹一孔之见而已。无论是了解施用绿肥,还是了解冬种森林作业对土壤生物的影响,都是极困难的事。但 Foreword Forest soil in the deciduous leaves, the decomposition and disappearance of animal remains, mainly by soil biological activity. Therefore, the application of green manure in forest land, of course, the activities of soil organisms has become the focus of the problem. Forest soil biological phases often subtlely change due to minor environmental differences and affect their ability to break down fallen leaves. In the woodland application of green manure, there are many factors such as the nature of green manure, application rate, period, frequency of application, soil conditions and application of meteorological conditions entangled together. The case described below is nothing more than a glimpse into the issue of giving complex influence to soil organisms. Whether it is to understand the application of green manure, or understand the impact of winter forest operations on soil organisms, are extremely difficult. but
