摘　　要：探讨紫色土和黄壤两类地区土壤养分对白夹竹笋品质的影响,得出栽培优质白夹竹笋的土壤养分条件,为紫色土、黄壤地区白夹竹笋用林的土壤养分管理提供理论依据。在雅安紫色土地区和都江堰黄壤地区各选择1片经人工经营的白夹竹林,每片竹林设置10 m×10 m的样地,重复8次。于2017年5月,对样地内采集的土壤和竹笋进行检测分析,应用多元回归方法筛选不同产区影响竹笋品质的土壤养分因子,并拟合竹笋营养物质与土壤养分含量的回归方程,得出两地白夹竹笋营养物质与土壤养分的关系。两个产地的土壤全氮和碱解氮含量偏高,有机质、全磷和有效磷含量偏低,土壤全钾和速效钾含量处于正常水平。黄壤产区竹笋品质整体优于紫色土产区,竹笋营养物质与土壤养分存在显著相关性(P<0.05)。紫色土地区影响白夹竹笋品质的土壤因子主要为土壤pH、有机质和有效磷;黄壤地区对竹笋品质产生影响的土壤因子是有机质、有效磷和速效钾。两个产区均缺乏有机肥和磷肥,氮肥施入偏高,经营管理为增加有机肥的施入,平衡氮磷钾肥的施入。土壤养分与白夹竹笋营养物质含量间存在显著相关性,可通过调节土壤理化性质和养分含量达到竹笋优质高产的目的。To explore the effects of soil nutrients in purple soil and yellow soil on the yield and quality of bamboo shoots,and the soil nutrient conditions for cultivating high-quality white bamboo shoots were obtained,which provide theoretical support for soil management of white bamboo shoots forests in two regions.One artificially managed bamboo forest was selected respectively in Ya'an purple soil region and Dujiangyan yellow soil region,and each bamboo forest was set with 10m×10m experiment plot,which was repeated for eight times.In May 2017,the soil and bamboo shoots samples collected in each experiment plot were detected and analyzed.The multiple regression method was used to screen the soil nutrient factors affecting the quality of bamboo shoots in different producing regions,and the regression equation between bamboo shoots nutrients and soil nutrient content was fitted.Finally,the relationship between nutrient components of bamboo shoots and soil nutrients was obtained.The results showed that the contents of total nitrogen and alkali hydrolyzable nitrogen in soil of two producing areas were high,but the contents of organic matter,total phosphorus and available phosphorus were low,and the contents of total potassium and available potassium were at normal level.The quality of bamboo shoots in yellow soil producing area is better than that of purple soil region,and there was a significant correlation between the nutrition of bamboo shoots and soil nutrients(P<0.05).The main soil factors affecting the quality of bamboo shoots in purple soil area were soil pH,organic matter and available phosphorus.The soil factors affecting the quality of bamboo shoots in yellow soil area were mainly organic matter,available phosphorus and available potassium.Both of the two regions were lack of organic fertilizer and phosphate fertilizer,and the nitrogen fertilizer application was on the high side.The management was to increase the application of organic fertilizer and balance the application of nitrogen,phosphorus and potassium f
