| Abstract: |
| To provide technical support for relay intercropping of ramie and tuber mustard，the orthogonal test
design was adopted to analyze the effects of different relay intercroppings of ramie and tuber mustard（different planting
densities，different tuber mustard varieties and different fertilizer rates，while ramie was“ Zhongzhu No.2”）on soil
available nutrients and four soil enzymes related with soil fertility. The results showed that planting density had no
significant influence on soil pH and available nutrient content，but the effects of different tuber mustard varieties and
different fertilizer rates on soil pH，available nutrients were significantly different. And different planting densites，
different tuber mustard varieties and different fertilizer rates had significant influences on soil enzymes related with soil
fertility. In the practical application of relay intercropping of ramie and tuber mustard，different intercropping ways
can be chosen according to soil conditions to gain the additional economic benefits（tuber mustard），and improve the
quality of soil at the same time. |
