采用田间试验根区取样的方式在等氮量、有机氮占20%的条件下,研究牛粪、秸秆、油枯有机肥与化肥配施在烤烟不同生长时期对植烟黄壤肥力的影响。研究结果表明:（1）牛粪、油枯处理更有利于烤烟成熟期有机质的分解;（2）油枯、牛粪处理全氮含量较高,有机肥的保肥性较化肥更好;（3）油枯处理在烤烟生长旺长期铵态氮、硝态氮、速效钾含量较高,更有利于烤烟的生长及品质的提高。施用有机肥后,在一定程度上能提高植烟土壤的肥力。

The effects of combined application of chemical fertilizer and organic fertilizers like cow dung,fowl dung,biogas residue and straw on nitrogen in tobacco planting yellow soil under condition of equal nitrogen and 20% organic nitrogen through field experiment of simpling with mash bags was studied. The results showed that organic fertilizer had a significant effect on soil nutrient transformation. The cow dung and dry processing is more conducive to the decomposition of organic matter. Dry cow dung,total nitrogen content,fertilizer and organic fertilizer is better than chemical fertilizer. Dry...
