- Abstract:
- In order to study the relationship between measure ments of soil erosion controling and improvement of soil physical and chemical properties,effects of five different intercropping patterns on physical and chemical properties of degenerate red soil were studied through five years’ field observation.The results showed that amelioration effects of soil properties were different depending on different intercropping patterns,i.e.amelioration effects of soil properties were different when the grass and tillage in the patterns were different.Intercropping with Paspalum notatum flÜgge and Cynodon dactylon overall coverage had the best effect on conserving water.Intercropping with Cynodon dactylon also had the best effect on improving soil bulk density,soil moisture,organic matter,soil total nutrients and soil available potassium.The functions of intercropping Paspalum notatum flÜgge and Cynodon dactylon were obviously better than that of intercropping crop in improving soil total nitrogen.The function of intercropping crop was better than that of intercropping different grass in improving soil total phosphorus and available nitrogen.Intercropping Bahia grass and crop could increase soil available phosphorus,and intercropping Cynodon dactylon & Paspalum wettsteinÜ hackle could decrease soil available phosphorus.The effects of horizontal intercropping on conserving soil nutrient were better than those of down slope farming.Therefore,the horizontal intercropping should be adopted in hilly region.
