Effects of Intercropping of Aromatic Plants with Tea on Physicochemical Properties and Soil Nutrients in Tea Plantation

  • 摘要: 为研究茶树与芳香植物间作对夏秋茶园土壤物理性状和土壤养分含量的影响,选择藿香、鼠尾草、须苞石竹、丛生福禄考、肥皂草5种芳香地被植物进行茶园行间间作覆盖试验,分别于6月和10月取样测定茶园不同土层中土壤的物理性状及养分的含量。结果表明:茶园间作芳香植物能控制茶园土壤pH降低,增加土壤相对含水量;在茶树生长的不同时期土壤养分的变化有明显差异,间作茶园茶树旺盛生长的6月份土壤有机质、全氮、碱解氮、速效磷和速效钾的含量显著降低,10月份土壤中的有机质、全氮、碱解氮、速效磷和速效钾的含量则显著高于清耕茶园;茶园短时间间作芳香植物会与茶树争夺养分,但长期间作芳香植物可增加土壤中有机质、全氮、碱解氮、速效磷和速效钾的含量,优化茶树生长的土壤环境。综合测定结果显示,茶园间作丛生福禄考、肥皂草和须苞石竹效果较好。

     

    Abstract: To investigate the effects of intercropping aromatic plants on soil physical properties and soil nutrients in tea plantation, intercropping Agastache rugose, Salvia japonica, Dianthus barbatus, Phlox drummondii and Saponaria officinalis were selected to carry out the experiment. Surface soil samples in different depth were collected in June and October to determine the soil physical properties and soil nutrients. The results indicate that intercropping aromatic plants reined in the decrease of soil pH and increased the soil moisture significantly. The changes of soil nutrients were obvious at different stages. The contents of soil organic matter, total nitrogen, available nitrogen, available phosphorus and available potassium of the tea plantation intercropped with aromatic plants decreased in June as plants grow rapidly, while the contents increased significantly in October compared with those in monocropping system. This suggests that aromatic plants compete with tea tree for soil nutrients in growth period. As time goes on, longterm intercropping aromatic plants can increase soil nutrient contents and improve the soil ecosystems of tea plantation. By the comprehensive analysis of the soil physical properties and soil nutrients, we consider that intercropping Phlox drummondii, Saponaria officinalisaromatic and Dianthus barbatus will be beneficial to the tea production.
