Abstract

Rice crop residues are one of the recalcitrant agricultural wastes in arid conditions. A laboratory experiment was conducted to decompose rice straw with woodlice and millipedes living in the dry steppes of Kalmykia in Russia. Five individuals of two species of woodlice (Armadillidium vulgare and Protracheoniscus kryszanovskii) or two species of millipedes (Brachydesmus assimilis and Cylindroiulus sp.) were placed in microcosms with soil and 2.5 g of rice straw. The straw mass significantly decreased for all species, by approximately 50% on average for the 4 months of the experiment. The content of organic matter in the soil before and after the experiment did not change significantly, which suggests that the selected species of woodlice and millipedes can consume and, thus utilize, rice straw, at least under experimental conditions.

在卡尔梅克州土壤中，Woodlice（Isopoda，Oniscidea）和千足虫（Myriapoda，Diplopoda）对稻草的分解实验

摘要

水稻作物残留物是干旱条件下顽强的农业废物之一。进行了一项室内实验，将生活在俄罗斯卡尔梅克干草原中的木虱和千足虫分解为稻草。五种个体，两种木虱（寻常的犰狳和Protracheoniscus kryszanovskii）或两种千足菌的物种（Brachydesmus assimilis和Cylindroiulus将其置于土壤和2.5克稻草的缩影中。对于所有物种，秸秆质量均显着降低，在实验的4个月中平均降低了约50％。实验前后土壤中有机质的含量没有显着变化，这表明至少在实验条件下，所选的木虱和千足虫物种可以消耗稻草，从而利用稻草。
