花岗岩侵蚀区山地绿肥种植试验研究
- Title:
- Research on the Planting Green Manure in the Eroded Granite Mountain District
- Keywords:
- granite; erosion; green manure; soil
- 摘要:
- 为探索改造利用花岗岩侵蚀劣地的有效措施，选择绿肥品种9个，进行了小区对比试验，对其适应性、生育期、鲜叶产量、土壤微环境的改善以及试验地的土壤改良情况等指标进行了综合测定，筛选出印度豇豆、大叶猪屎豆、小叶猪屎豆和木豆4个品种。试验表明，在侵蚀劣地种植绿肥，可迅速覆盖地表，控制水土流失，见效快，收益大。试验区与对照区相比，有机质、全氛、全磷分别增加了1%，0.01%，0.02%，土壤容重下降了0.28g/cm3。由此可见，种植山地绿肥是水土流失区改良土镶的一条有效途径。
- Abstract:
- In order to probe effective measurement to reform and exploit the bad eroded granite soil, we chose 9 kinds of green manure and made contrast plot experiments, comprehensively measured indexes including its adaptability,child-bearing period, Output of fresh leaves and the improvement of the soil microenvironment,the improvement of the soil on the exploiting field,at last, we selected 4 sorts of legume. The experiments showed that it could quickly cover the surface, control the soil and water loss, gain quick efficiency and many benefits that planting green manure on bad eroded soil. By comparing the experimental plots with the contrast plots,the whole-nitrogen rose 0.01 percent, the whole-phosphate 0.02 percent and the organism 1 percent. Thus it is a efficient path to improve soil of loss district by planting greon manure on mountain area.
