| Abstract: | To provide reference for reasonable use of water and fertilizer resources in dry-land of Loess Plateau,the study on the change of soil nutrient and water was conducted under the condition of 22-year Triticum aestivum L.succession based on the long-term fertilizer experiment.The six treatments were no fertilizer(CK),nitrogen fertilizer(N),phosphate fertilizer(P),manure fertilizer(M),nitrogen and phosphate fertilizers(NP),nitrogen and phosphate fertilizers with manure(NPM).Nutrient in tilth soils(0-20cm),and ... |
