施用不同粪肥对土壤理化性质及玉米产量的影响

在比较分析鸡、牛、猪三种粪肥养分和污染物含量基础上,以玉米为试材,研究不同粪肥与化肥配施对土壤理化性质及玉米产量变化的影响。试验结果表明：农田配合施用粪肥能够明显提高玉米产量,改善土壤结构,减少化肥的施用量。其中试验以施用鸡粪效果最好,土壤理化性质明显提高,与对照相比,全氮量、速效氮、全磷量、速效磷、速效钾含量及有机质含量分别提高39.33%、84.8%、27.65%、109.7%、12.9%和11.35%。玉米产量比对照增产12.81%,化肥施用量减少30%以上。

The Influence of Application of Different Manure on Soil Physical and Chemical Properties and Maize

Based on analysis three kinds manure nutrients of chicken, cattle, pigs and contaminants, the paper studied the influence of application of different manure and chemical fertilizer on soil physical and chemical properties and corn yield with corn as test material. The results show that： the application of proportion of farmland manure and fertilizer can significantly increase corn yield,improve soil structure, reduce the amount of fertilizer application. It is best test the application of chicken manure of all tests, it can increase physical and chemical properties of soil significantly with the comparison, total nitrogen, available nitrogen, total phosphorus amount of available phosphorus and potassium content and content of organic matter is increased by 39.33%, 84.8%, 27.65%, 109.7%, 12.9% and 11.35%. Maize yield increased 12.81 percent higher than the comparison, fertilizer application reduced 30%.
