皖南茶区多少年来一直沿袭着深秋挖(即秋季深耕)的习惯,茶农称之为“七挖金、八挖银”,认为这是确保第二年春茶增产的重要措施。但笔者对这个问题有不同的看法,于是进行了由深秋挖改为施秋肥的试验。本试验在歙县潜口乡红旗队进行,试验茶园为13年的成龄茶园,茶树长势和单产均一致。试验分三个处理,Ⅰ处理为茶农常采用的秋 For many years, southern Anhui tea-drinking area has followed the habit of digging in autumn (that is, deep plowing in autumn).

The trial tea plantation was a 13-year-old tea plantation. The growth of tea tree and yield were consistent. The test is divided into three treatments, Ⅰ treatment is often used by tea farmers autumn
