PH is adjusted by putting S powder in 24 cultivation substrate combinations;these cultivation substrates gradually reach a relatively stable level after 120 days.The results show that S powder of 0.5-1.0kg/m3 added to brown loam is the best,and S powder of 1.0-1.5kg/m3 added to paddy soil is also the best.These two cultivation substrate combinations are perfectly fit for blueberry cultivation.All the raw materials for blueberry cultivation are agricultural and forest residues,which can not only reduce the cost but also meet the requirements of agricultural cycle economy and ecological agriculture.%24个栽培基质组合加S粉调节pH值,120d后达到稳定状态。实验结果表明棕黄壤土加S粉0.5-1.0kg/m3较合适,水稻土加S粉1.0-1.5kg/m3较为适宜。2种专用营养基质组合均可达到蓝莓种植所需要的营养水平和对土壤理化指标的要求,完全可以满足蓝莓生长的需要,所用原材料均为当地的农林废弃物,符合农业循环经济和生态农业的要求。
