- Abstract:
- By means of fields investigation and lab experiments, based on the planted grassland, the nature grassland and the slope farmland of the small Ronglei river watershed in Changshun, we have examined soil total nitrogen and alkaline hydrolysis nitrogen, total phosphorus and available phosphorus, total potassium, available potassium, pH and the organic matter, revealed the influence of the grassland mode on the soil fertility, and comprehensively evaluated the soil fertility by analytic hierarchy process (AHP) in the small Ronglei river watershed in Changshun. The result showed that: after the artificial grass measures had been carried out, soil’s total nitrogen content of farmland relatively increased by 42.64%, alkali solution nitrogen increased by 50.86%, the improvement of alkali-hydrolysable nitrogen in the subsoil layer (20—30 cm) was the most obvious. The content of soil total phosphorus relatively increased 45.24%, available phosphorus increased by 23.58%, the contents of total phosphorus in the farmlands are relatively deficient if compared to grassland, but the level of available P used by crops was higher than that of artificial grassland; soil total potassium and available potassium contents of farmland decreased, pH values presented no significant change; the content of total potassium relatively decreased by 43.28%, available potassium decreased by 37.32%; the content of soil organic matter relatively increased by 77.24%, the contents of soil organic matter in topsoil (0—10 cm), middle, and the deep layers increased by 48.06%, 85.58% and 107.78%, respectively, there was great improvement in the levels of soil organic matter in middle and deep layers. The Integrated fertility index of natural grassland is the maximum and the slope farmland is the minimum. Fertility index of natural grassland is 1.09 times of the artificial grassland, fertility index of natural grassland is 1.14 times of the farmland artificial grass. Fertility index of farmland artificial grass is 1.05 times of the slope farmland. The overall level of soil fertility was improved.
