| 摘 要： | 本文通过水培试验，以蚓粪（蚯蚓作用过的牛粪）和牛粪提取的水溶性有机物（DOM）为添加物，研究蚓粪和牛粪DOM对黑麦草生长的影响。结果表明：两种DOM均显著增加了黑麦草地上和地下部的生物量以及根系的长度、表面积、体积和根尖数（p＜0.05）；且对根系的促进作用显著大于茎叶；各项指标都以添加20g蚓粪DOM的处理为最大，这说明来自蚓粪的DOM对植物的影响显著优于牛粪DOM，并且高浓度的DOM效果显著优于低浓度的DOM。

| Abstract: | Effects of dissolved organic matter (DOM), extracted from earthworm casts and cattle manure, on the ryegrass growth were studied under hydroponics condition. There were five treatments of two different concentration of DOM extracted from earthworm casts and cattle manure (10g earthworm casts or cattle manure DOM, 20g earthworm casts or cattle manure DOM) and the control, The results show that DOM extracted from earthworm casts significantly increased biomass of shoots and roots of ryegrass, and length, surface area, volume, and number of tips of the root system (p＜0.05); the growth of the root was promoted more significantly than the shoot; each indicator reached the maximum quantity under the treatment of 20 g earthworm casts DOM, which explained that the earthworm casts DOM significantly promote the ryegrass growth than cattle manure DOM. In addition, the high concentration of DOM had better effects on the ryegrass growth than the low concentration of DOM. Overall, it could be inferred that the earthworm casts DOM significantly promote the growth of plants. |
