摘要

Epigeic earthworms are often used to restore of soil quality. Trophic group of nematodes plays an important role in driving of decomposition rate of organic matter. Ultisols is characterized with the soil biological quality that is not suitable for the development of vegetable crops. The objective of this study was to analyze the effect of epigeic earthworms on the abundance of nematode trophic groups during the decomposition of organic material in litter bags under cropping of tomato (L. esculentum Mill.) on Ultisols. Epigeic species of earthworms (Lumbricus sp.) were used to modify the soil environment. The experiment treatment consisted of nine combinations of three types of organic matter and three individual levels of earthworms. The organic material consisted of litters of C. odorata, I. cylindrica and Colopogonium sp. The number of earthworms consisted of 0, 20 and 40 individuals plot~(-1). Each combination of each litter type and number of earthworms was repeated three times in an experimental randomized block design. Research found three trophic groups of nematodes, namely root-herbivorous, bacterivorous and predaceous in the litter bags. Abundance of root-herbivorous between combinations was significantly different at 30 days after exposure. Abundance of bacterivorous nematodes among treatments was significant at 60 days after exposure, which at the 30 and 90 days were not significant. Abundance of predaceous was differed significantly at the 60 and 90 days, and at the 30 days was not significantly different. Constant of decomposition rate of each organic matter under different number of earthworms was similar. Coefficient correlation showed that relation between the constant of decomposition rate with abundance of root-herbivorous was positive at 30 days and negative with bacterivorous at the 90 days. Research concluded that the introduction of epigeic earthworms influenced trophic group dynamics of nematodes during the decomposition of organic material under tomato cropping on Ultisols.

Odorata，I. Cylindrica和Colopogonium sp组成。蚯蚓的数量由0,20和40个个体图组成〜（-1）。在实验随机块设计中重复每个垃圾类型和蚯蚓数的每个组合，重复三次。研究发现了三种营养的线虫组，即根草性，诱导的砂袋中的根草食物，诱导。在接触后30天内，组合之间的丰富的根草性具有显着差异。在暴露后60天的治疗中抑制治疗中的丰度显着，在30和90天不显着。在60和90天内，预饱和度明显不同，并且在30天内没有显着差异。不同数量的蚯蚓下每个有机物的分解率的常数相似。系数相关表明，在30天的30天内，具有丰度的根草性阳性的分解率之间的关系，并且在90天内用诱导效应。结论是，引入Epigeic蚯蚓在Ultisols上番茄种植下有机材料分解过程中对线虫的营养群体动力学。
