| 摘 要： | 通过在茶树+橡胶林地内进行了有机肥施用量及蚯蚓投放量对其林地土壤改良效果的研究。结果表明,不同的有机肥(牛粪)施用量+蚯蚓投放量对其林地土壤的综合改善作用是20 kg蚯蚓+20 kg牛粪10 kg蚯蚓+20 kg牛粪5 kg蚯蚓+20 kg牛粪10 kg蚯蚓+10 kg牛粪10kg蚯蚓+5 kg牛粪20 kg牛粪对照;在施用相同数量有机肥牛粪的条件下,投放蚯蚓数量多的处理对茶树+橡胶林地土壤物理性状改善的效果大于投入数量少的处理,但投放20kg蚯蚓与投放10kg蚯蚓对其林地土壤物理性状改善作用没有明显差别。而在投放相同数量蚯蚓的条件下,则是施用牛粪多的比少的明显。各处理对茶树+橡胶林地土壤物理性状及化学性质各指标的效果较一致,并且对林地0~20 cm土层及20~40 cm土层的土壤物理性状及化学性质均有改善作用,其改善效果是0~20 cm土层优于20~40 cm土层,但差异不显著。
