不同施肥措施对黄泥田土壤养分及水稻产量的影响

为农业有机废弃物的合理科学利用提供参考,在湖北省孝昌县单季稻区利用田间试验研究6种施肥措施对黄泥田土壤肥力及水稻产量的影响。结果表明:不同施肥措施对黄泥田土壤有效磷与速效钾含量的影响显著,对有机质、全氮及碱解氮含量的影响不明显。在6种施肥措施中,以化肥+畜禽粪肥配施黄泥田土壤的有机质、全氮、碱解氮、有效磷和速效钾含量最高,分别为23.06 g/kg、1.34 g/kg、111.66mg/kg、30.77mg/kg和148.33mg/kg,且有效磷和速效钾含量显著高于其他施肥措施(P0.05);稻谷和稻草产量也最高,分别为9 638.38kg/hm~2和11 118.39kg/hm~2,也显著高于其他施肥措施(P0.05);水稻的综合农艺性状好。因此,在黄泥田水稻生产过程中,采用化肥和畜禽粪肥配施可有效培肥其土壤,提高水稻产量。

Effects of Different Fertilization Patterns on Soil Fertility and Rice Yield of Yellow Clayey Paddy Soil

The effects of six fertilization patterns on soil fertility and rice yield of yellow paddy clayey paddy soil were studied by a field test in single cropping rice area of Xiaochang County,Hubei to provide a reference for rational and scientific utilization of agricultural organic waste.Results:Different fertilization patterns have the significant effect on available P and rapid available potassium content of yellow clayey soil but no obvious effect on organic matter,total nitrogen and available nitrogen content of yellow clayey paddy soil.The organic matter,total nitrogen,available nitrogen,available P and rapid available K content of yellow clayey paddy soil under the chemical fertilizer + livestock and poultry manure combined application pattern is the highest among six fertilization patterns.The organic matter,total nitrogen,available nitrogen,available P and rapid available K content of yellow clayey paddy soil under the chemical fertilizer +livestock and poultry manure combined application pattern is 23.06 g/kg,1.34 g/kg,111.66 mg/kg,30.77 mg/kg and 148.33 mg/kg respectively and the available P and rapid available K content is higher than other fertilization patterns significantly.The rice and straw yield under the chemical fertilizer + livestock and poultry manure combined application pattern is the highest among six fertilization patterns.The rice and straw yield under the chemical fertilizer + livestock and poultry manure combined application pattern is 9 638.38 kg/hm-2and 11 118.39 kg/hm2 respectively and significantly higher than other fertilization patterns also.In conclusion,the chemical fertilizer + livestock and poultry manure combined application pattern can improve soil fertility and rice yield in rice production of yellow clayey paddy soil.
