不同肥料对茶叶产质量及土壤微生物量的影响

摘要

为茶叶产质量的提高及茶园土壤结构的改善提供参考,采用田间试验试方法研究鸡粪(有机肥)、无机肥、鸡粪(有机肥)+无机肥及不施肥对茶叶产量质及土壤微生物量的影响.结果表明:施用不同肥料均能提高茶叶的产量和品质,增加土壤微生物量,且除施用无机肥对茶叶产量和品质的影响不显著外,施用其余肥料均能显著提高茶叶的产量及品质;鸡粪(有机肥)+无机肥配施对茶叶产质量和土壤微生物量碳含量的提升效果最明显,单施鸡粪(有机肥)对土壤微生物量氮含量的提升效果最佳.因此,鸡粪(有机肥)与无机肥配施能显著提高茶叶的产量和品质,增加土壤微生物量碳,单施鸡粪(有机肥)对增加土壤微生物量氮的效果较明显.%The field experiment was used to study the effects of chicken manure,inorganic fertilizer,chicken manure + inorganic fertilizer and no fertilizing on yield and quality of tea and soil microbial biomass and to provide a reference for increasing yield and quality of tea and improving soil quality of tea gardens.Results:Applying different fertilizers all can improve yield and quality of tea and increase soil microbial biomass.Applying chicken manure and chicken manure + inorganic fertilizer both can improve yield and quality of tea significantly but applying inorganic fertilizer has no obvious effect on yield and quality of tea.Applying chicken manure + inorganic fertilizer has the significant promoting effect on yield and quality of tea and soil microbial biomass carbon content and applying chicken manure has the best promoting effect on soil microbial biomass nitrogen content.In conclusion,the combined application of chicken manure + inorganic fertilizer can improve yield and quality of tea and soil microbial biomass carbon content significantly.Applying chicken manure can increase soil microbial biomass nitrogen content obviously.
