| 摘 要： | 利用田间小区试验,研究了无机肥配施不同用量有机肥对菜地土壤氮素径流流失的影响.结果表明,施肥显著增加菜地土壤氮素径流流失量.单施无机肥处理总氮、硝态氮和铵态氮流失量均最高,分别为4.20,1.22,2.30kg/hm2.配施有机肥可降低不同形态氮流失量,且随有机肥配施量增加而显著降低.配施高量有机肥处理总氮、硝态氮和铵...

| Abstract: | A field plot experiment was conducted to study the effects of combined application of organic and inorganic fertilizer on soil nitrogen runoff in vegetable field.The results showed that fertilizer application increased the nitrogen loss via runoff.The highest losses of total nitrogen,nitrate nitrogen and ammonium nitrogen were 4.20,1.22,2.30 kg/hm2,respectively,as treated by inorganic fertilizer alone.The nitrogen loss decreased significantly with the increased combined application of organic and inorganic ... |
