不同类型生物质材料改良茶园土壤酸度的效果评价
|
摘要
通过室内培养试验,研究稻秸、麦秸、生物质炭、羊粪等4种生物质材料对茶园土壤酸度的改良效果。结果表明,在茶园土壤中施入稻秸、麦秸、生物质炭、羊粪等4种物料培养90d后,土壤pH值分别比对照显著提高了0.72、0.53、0.77、0.72个单位(2%添加量)和0.89、0.76、1.16、1.32个单位(4%添加量)。4种生物质材料均能显著降低土壤交换性酸和交换性铝含量、增加土壤盐基离子量以及提高土壤盐基饱和度,且改良效果随着施用量的增加而提高。只有羊粪处理能够显著提升土壤阳离子交换量和硝态氮含量,生物质炭处理对土壤硝态氮含量的影响不显著,麦秸和稻秸反而降低了土壤硝态氮含量。综合比较,羊粪改良茶园酸化土壤的效果最佳,生物质炭次之。
This indoor incubation study aimed to evaluate the ameliorating effects of four biomass materials,including rice straw,wheat straw,biochar and sheep manure,on acidic soil at a tea plantation.The results showed that the pH of the soil incorporated with rice straw,wheat straw,biochar,and sheep manure increased by 0.72,0.53,0.77,and 0.72 units,respectively,at 2%addition level,and 0.89,0.76,1.16,and 1.32 units,respectively,at 4%addition level over control.In addition,the applications significantly decreased the contents of exchangeable acidity and exchangeable aluminum,while increased the exchangeable and saturation on cations in the soil.The amelioration of the soil was enhanced with increasing biomass addition.Different from the other materials,sheep manure significantly increased the cation exchange capacity(CEC)and nitrate nitrogen(NO3-N)content in soil,biochar exerted no significant effect on NO3-N,and rice or wheat straws significantly decreased NO3-N.Consequently,sheep manure followed by biochar were considered the choice materials for acid alleviation on tea plantation soil.
