摘要
茶园土壤酸化会严重影响茶叶品质。本文以贵州省湄潭县核桃坝村的茶园土壤为研究对象,采用室内盆栽试验,分层次将茶园土壤样品混合5%、10%、15%的茶树枝生物质炭,观察茶园土壤对多年生黑麦草生长的影响。结果表明,添加茶树枝生物质炭后,茶园土壤得到明显改良,显著增加了土壤有机碳含量和土壤pH值,促进了黑麦草生长。
Soil acidification in tea plantations can seriously affect tea quality.The soil of tea plantation in Hetaoba Village of Meitan County,Guizhou Province was studied.In the indoor pot experiment,the soil samples in different layers were mixed with 5%,10%and 15%of the biochar of teatree branches to observe the effects of the soil on the growth of perennial ryegrass.The results showed that the soil quality in the tea plantation wasimproved by adding biochar,the soil organic carbon content and soil pHvalue significantly increased,and the growth of ryegrass was promoted.
