| 摘 要： | 在黄刚土和马肝土上进行 3年 6季的田间试验。在稻麦轮作制中每季施用稀土制剂 0 .0 0、1 8.75、3 7.50、75.0 0、3 75.0 0 kg/hm2 ,在油豆轮作制中每季施用稀土制剂 0 .0 0、1 5.0 0、3 0 .0 0、60 .0 0、3 0 0 .0 0 kg/hm2 。试验结束时 ,测定土壤微生物数量以及土壤的 p H状况。结果表明 :在油豆轮作制中 ,施用 1 5～ 3 0 kg/hm2的稀土制剂后土壤细菌、真菌数量及微生物总量明显增加 ,而放线菌数量在这一稀土用量范围内明显减少 ;在稻麦轮作制中亦有相近趋势 |

| Abstract: | Experiments were conducted on huanggang soil and magan soil for six cropping seasons during 3 years. The rare earth dosages of 0.00, 18.75, 37.50, 75.00, 375.00 kg/hm 2were applied in every season of rice wheat rotation and 0.00, 15.00, 30.00, 60.00, 300.00 kg/hm 2 of rape bean rotation. The microbe amount and the pH of soil were determined by the end of the experiment. The results showed that the quantity of soil bacteria, fungi and total microbe increased apparently after applying rare earth with 15~30 kg/hm 2 in rape bean rotation, while actinomyces decreased significantly in this applying range. The same trend appeared in the rice wheat rotation. |
