Effects of rotation cropping system on soil nutrients in hilly region of red soil in south Hubei
摘要
Abstract
Soil nutrients content of upland, paddy field and vegetable plot changed from paddy field were measured under the 10 rotation cropping systems in the hilly region of red soil in south Hubei. The organic matter and nitrogen were commonly low and the phosphorus was deficiency, where the potassium was gradually reduced in the area. It was found that the content of organic matter and nitrogen in the rotation cropping system could be set in sequence from high to low, for paddy field, vegetable plot changed from paddy field, and upland, while the content of phosphorous might be set an other sequence, for vegetable plot changed from paddy field, paddy field, and upland. The content of potassium was remarkable lower in paddy field than in upland, especially low in three harvests a year (rape seed-watermelon--rice). Changing to vegetable plot can remarkable reform soil moisture region of paddy soil.关键词
