- 摘要:
- 为了进一步探明永定河河滨绿化带土壤生态修复的障碍因子——水分，采用野外定位试验的方法，对永定河河滨绿化带进行了覆盖保墒试验，研究了不同石块覆盖度对土壤含水率和植物生长状况的影响，结果表明：石块覆盖度在60%～80%时，土壤保墒效果最好；波斯菊和紫茉莉石块覆盖度分别为10%和60%时，各项生长指标最高；采用灰色关联度对土壤、植物进行综合评价，分析得出永定河河滨绿化带石块覆盖度为60%的紫茉莉评价结果优于石块覆盖度为10%的波斯菊。研究结果可为保墒技术的实际应用提供理论参考。
- Abstract:
- In order to further explore the moisture content which is an obstacle factor in the streamside greenbelt of soil ecological rehabilitation along the Yongding River, using location test in the countryside, and based on the preservation of soil moisture experiment in Yong ding streamside green belt, the effects of different rock coverage on soil moisture content and plant growing situation were studied. The result demonstrated that when the rock coverage was 60%~80%, the soil moisture was the highest;the rock coverage of Calliopsis and Mirabilis jalapa was 10% and 60%, respectively, each growing index was the highest. Soil and plants were evaluated by using the method of grey relational grade. The analysis demonstrated that 60% of rock coverage in Mirabilis jalapa belt was better than 10% of rock coverage in Calliopsis belt along the streamside green belt of Yongding River. The research result can be set as a reference for the practice of soil moisture preservation.
