为研究施用有机垃圾肥料对林地土壤动物蚯蚓的影响,对上海郊区3个基地施用不同量有机垃圾肥料的林地中蚯蚓的数量和组成进行了调查。研究发现,赤子爱胜蚓(Eisenia fetida)和腔蚓(Metaphire sp.)两种蚯蚓数量比约为1.78∶1。在老港和金山基地中,蚯蚓的数量随着撒施有机垃圾肥料量的增加而增加,而在沟施的操作下蚯蚓数量的变化起伏较大,这一变化与有机垃圾肥料在林地沟施不均匀密切相关。施用有机垃圾肥料后,蚯蚓数量的增加会导致生态系统地下部分物质和能量循环产生变化;在蚯蚓活动和取食过程中,通过其对有机物质的分解转化,会促进氮、磷循环,从而给林地生态系统带来较多的有利影响。
In order to study the effect of organic manure on earthworms of soil animals in the forestland, the quantity and composition of earthworms in the forestlands with different amounts of organic manure and fertilizers applied to three sites in the suburbs of Shanghai were investigated. The results showed that the ratio of earthworms between Eisenia fetida and Metaphire sp. Was about 1.78:1. In Lao Gang and Jinshan Base, the number of earthworms increased with the amount of organic waste manure applied, while the amount of earthworm fluctuated greatly under the operation of furrow. This change was related to the organic fertilizer application Unevenly closely related. After the organic manure is applied, the increase of the number of earthworms will lead to the change of material and energy circulation in the underground part of the ecosystem. During the earthworm’s activities and feeding processes, the decomposition and conversion of organic substances will promote the cycling of nitrogen and phosphorus, Woodland ecosystems bring more beneficial effects.
