摘要: 采用室内培养的方法,研究了不同类型生物质材料对3种不同酸度茶园土壤的改良效果。结果表明,在酸性茶园土壤中加入一定量的生物质材料培养45βd后,林场茶场、灵谷茶场和岭下茶场3种土壤的pH值较对照均有不同程度的提高,分别平均提高了0.44、0.31和0.26个pH单位。同时,加入生物质材料能显著降低土壤交换性酸、交换性铝、总可溶性铝和总单核铝含量,其中,以牛粪、秸秆堆肥和商品有机肥的效果更显著。此外,供试生物质材料在增加土壤交换性盐基数量和提高土壤盐基饱和度、土壤阳离子交换量、土壤有机质含量方面的效果,以作物秸秆炭最为显著。

Abstract: The amelioration effects of different biomass materials applied to three acidic tea garden soils were examined with the incubation experiments. The results indicated that the pH of three soils (LC, LG and LX) increased by 0.44, 0.31 and 0.26 units averagely while the contents of soil exchangeable acidity, exchangeable aluminum, total soluble aluminum, and total monomeric aluminum decreased significantly after biomass materials treatment for 45 days. Among different biomass materials, the amelioration effects of cow dung, straw compost and commercial organic fertilizer were more prominent than the others. The straw carbon was more effective than other materials in increasing the exchangeable cation contents and the degree of soil base saturation, as well as the soil cation exchange capacity and soil organic matter contents. These results help to better understand the mechanisms of the amelioration.

Key words: acidic tea garden soil, soil acidity, biomass materials, effects of amelioration
