桂南山区油茶人工林土壤养分状况调查与评价——以高峰林场为例

Investigation and Evaluation of Soil Nutrient Status of Camellia oleifera Plantation in Southern Guangxi Mountainous Areas—Taking Gaofeng Forest Farm as an Example

良好的土壤养分状况是保证油茶人工林高效经营的关键,调查和评价桂南山区油茶人工林的土壤养分状况,以确保更有效地维护和改善油茶林的土壤环境,促进油茶果产量和品质的提升。通过采集土壤样品,测定了8个养分指标,包括土壤有机质、全氮、全磷、全钾、有效氮、有效磷和有效钾,以期了解土壤的养分含量和有效性。结果表明:该油茶林地的土壤养分含量较高,有机质、全氮、全磷和全钾的平均值分别为22.56、1.05、0.26和8.62 g/kg。同时,有效氮、有效磷和有效钾的含量也相对较高,分别为54.18、1.67和36.88 mg/kg。根据土壤养分指标的评价标准,该油茶林地的土壤养分状况良好,但需要采取适当的管理措施来保持土壤肥力和提高油茶的产量和质量。

Good soil nutrient status is the key to ensuring efficient management of Camellia oleifera plantations.This study aims to investigate and evaluate the soil nutrient status of Camellia oleifera plantations in the mountainous areas of southern Guangxi,in order to ensure more effective maintenance and improvement of the soil environment of Camellia oleifera plantations,and promote the increase of Camellia oleifera fruit yield and quality.By collecting soil samples,eight nutrient indicators were determined,including soil organic matter,total nitrogen,total phosphorus,total potassium,available nitrogen,available phosphorus and available potassium,in order to understand the content and availability of soil nutrients.The research results indicate that the soil nutrient content of the Camellia oleifera forest is relatively high,with the average values of organic matter,total nitrogen,total phosphorus,and total potassium being 22.56,1.05,0.26,and 8.62 g/kg,respectively.At the same time,the content of available nitrogen,available phosphorus,and available potassium is also relatively high,at 54.18 mg/kg,1.67 mg/kg,and 36.88 mg/kg,respectively.According to the evaluation criteria for soil nutrient indicators,the soil nutrient status of the Camellia oleifera forest is good,but appropriate management measures need to be taken to maintain soil fertility and improve the yield and quality of Camellia oleifera.
