本文是对安徽祁门和十字铺、江苏宜兴和深水等地不同肥力水平的茶园土壤腐殖质含量、组成与性质的研究。土壤类型包括黄壤,红壤和黄棕壤。三个地区茶园土壤腐殖质组成都以富里酸为主,不同地区HA/FA值自黄壤向黄棕壤递增,同一地区高产茶园土壤HA/FA值大于低产茶园土壤,胡敏酸光密度值以黄壤最高,红壤居中,黄棕壤最低。
This paper is on the humus content, composition and nature of tea plantation soils with different fertility levels in Qimen and Cross Shop in Anhui Province, Yixing and Sham Shui in Anhui Province. Soil types include yellow soil, red soil and yellow brown soil. The humic composition of the tea soils in the three areas was dominated by fulvic acid. The HA / FA values increased from yellow soil to yellow brown soil in different areas. The HA / FA values of the high-yielding tea plantations in the same area were higher than those in the low-yielding tea plantation soils. Highest, middle red soil, yellow brown minimum.
