不同有机无机肥配施对烟田土壤养分有效性的影响

摘要

Through the acquisition of lfue-cured tobacco at different growth stages of soil sample, analyzed the indicators such as total nitrogen, total phosphorus, total potassium, available nitrogen, available phosphorus, available potassium, organic matter and pH value and other indicators in soil, studied the effects of different organic and inorganic combined fertilization on soil nutrient availability in tobacco ifeld. The results showed that when lees partial substituteorcompleted substitute farmyard manure and commercial organic fertilizer with adding microbial fertilizers, it was beneifcial to improve soil nutrient availability, but had no signiifcant effect on soil pH value.Therefore, with the lees instead of organic fertilizer and manure tobacco planting practices is desirable.%通过采集烤烟不同生长时期的土壤样本，分析土壤中全氮、全磷、全钾、速效氮、有效磷、速效钾、有机质和pH值等指标，研究了不同有机无机肥配施对烟田土壤养分有效性的影响。结果表明：酒糟部分替代和全部替代农家肥和商品有机肥并且添加微生物肥料时，有利于提高土壤养分有效性，但对土壤pH值的影响不显著。因此，用酒糟代替有机肥和农家肥种植烤烟的做法是可取的。
