| Abstract: |
| To address the agricultural and ecological problems that are becoming more severe, secondary salinization of soil in Qinwangchuan irrigated area, Gansu Province, was selected to investigate the effects of B. vulgaris and A. hypochondriacus on pH value, salt ion (Na+、Ca2+、Cl-、SO42-) contents, electronic conductivity (EC) of soil, seedling rate, EC and yield of crops. In this research, three cultivation patterns were used, including flat sowing without mulch (CK), ridge sowing without mulch (R) and ridge sowing with plastic mulch (R+P). The result indicated that significant effects of salt-tolerant crop on desalination improvement of soil were discovered, especially under the R+P and R cultivation patterns. Under R+P pattern, after harvesting B. vulgaris and A. hypochondriacus, soil salt ion concentration was decreased by 4.8%～7.4%, and 4.7%～6.5%, respectively, and EC of soil was significantly decreased by 16.7%～28.6% and 12.8%～30.9% from CK, respectively. Under R+P cultivation pattern, the leaf EC of B. vulgaris and A. hypochondriacus became significantly decreased by 22.9% and 14.9%, respectively. The successful seedling rate was significantly enhanced for A. hypochondriacus. However, cultivation patterns were found to have no influence on the yield of both crops. |
