冬小麦、夏玉米一体化垄作的养分利用研究
Nutrients utilization of integrative ridge planting system of winter wheat and summer maize
摘要
Abstract
The nutrient uptake and utilization of winter wheat and summer maize under conventional flat planting and integrative ridge planting system were studied in the experimental plot of Xunxian Agricultural Science Research Institute during 2005 -2007. Result showed that, comparing with that under the flat planting system, nitrogen,phosphorus and potassium uptake of winter wheat and summer maize increased under integrative ridge planting system by 14. 18％, 9. 20％ and 5.90％, harvest indices increased by 2. 13％ and 2. 42％, and yield increased by 4. 23％ and 9. 61％, respectively. The yield of whole year was increased by 7. 33％ on average. The two-year experiment indicated that soil fertility could be improved under integrative of ridge culture compared to that of traditional flat culture.关键词
