| 中文摘要: |
| 探讨化学防除狼毒（Stellera chamaejasme L.）对青海湖地区草地土壤化学性质的影响，旨在揭示化学防除狼毒措施的利与弊。对青海湖南岸化学灭除狼毒草地和非灭除草地取土壤样品，室内分析土壤化学性质。结果表明，化学防除草地中狼毒，对草地土壤pH、速效氮、速效磷有明显的抑制作用，而有利于翌年草地有机质、全钾的明显增加。化学灭除狼毒措施对草地土壤化学性质在0~30cm土层内随土壤深度的变化规律没有明显的影响。 |
| 英文摘要: |
| Researching the effect of chemical control of Stellera chamaejasme L. on soil chemical properties in grassland in Qinghai Lake area is to review the advantages and disadvantages of chemical control of S. chamaejasme L.Collecting soil samples from chemical control of S. chamaejasme L. and non-chemical control of S. chamaejasme L. in grassland respectively, soil chemical properties were analyzed. Results showed that chemical control of S. chamaejasme L.obviously inhibited the soil pH, available nitrogen and available phosphorus, indicating that S. chamaejasme L. was benefit to improve and sustain soil fertility. The chemical control of S. chamaejasme L. had no benefit to assemble the available nitrogen and phosphorus, but it had benefit to increase the total K and organics of the soil in following year. However, the chemical control of S. chamaejasme L. had no signifcant effect on the soil chemical properties in the 0~30 cm soil layer of the grassland with the soil depth. |
