摘要
通过5年田间定位试验,研究了施用不同种类有机肥(牛粪、鸡粪、猪粪和堆腐肥)对黑土磷素含量的影响。结果表明:与不施肥(ck)相比,施用有机肥增加了土壤全磷、速效磷、无机磷组分(包括Ca2-P、Ca8-P、Ca10-P、Al-P、Fe-P和O-P)及有机磷组分(包括活性有机磷、中等活性有机磷、中等稳定性有机磷和高稳定性有机磷)的含量。其中,Ca2-P的增加幅度高于其他无机磷组分,活性有机磷和中等活性有机磷的增加幅度高于其他有机磷组分。不同种类有机肥相比,施用猪粪和鸡粪后土壤各形态磷素的含量均高于堆腐肥和牛粪处理。相关分析结果表明,速效磷与Ca2-P和中等稳定性有机磷的相关性最高,而与Ca10-P和中等活性有机磷的相关性最低。上述结果表明,施用有机肥可增加土壤不同形态(尤其是植物有效态)磷素的含量,猪粪和鸡粪对土壤磷素的贡献大于牛粪和堆腐肥。
The effects of different organic manures(cow manure,chicken manure,pig manure and composting manure)application on phosphorus content in black soil were studied by field plot experiment for 5 years.The results showed that,compared with no fertilizer(ck),the contents of total phosphorus,available phosphorus,inorganic phosphorus fractions(i.e.,Ca2-P,Ca8-P,Ca10-P,Al-P,Fe-P and O-P)and organic phosphorus(i.e.,labile organic phosphorus,moderate labile organic phosphorus,moderate stable organic phosphorus and high stable organic phosphorus)in soil increased after the application of organic manures.The increase in Ca2-P was higher than that of other components of inorganic phosphorus,and labile organic phosphorus and moderate labile organic phosphorus increases higher than other organic phosphorus fractions.Among the different kinds of organic manures,the contents of different forms of phosphorus in soil were higher than those of composting and cow manure.Correlation analysis showed that available phosphorus had the highest correlation with Ca2-P and moderate stable organic phosphorus,and lowest correlation with Ca10-P and moderate labile organic phosphorus.The results showed that the application of organic manures increases the content of different forms of phosphorus in soil(especially the available phosphorus in plants),and the contribution of pig manure and chicken manure to soil phosphorus is greater than that of cow manure and compost manure.
