摘要
在亚热带赤红壤区研究沟叶结缕草施用有机肥对土壤性质及草坪质量的影响。结果表明 ,两种有机肥均能改善土壤通透性 ,增大土壤持水量 ,施肥一年后土壤 p H值降低。施蘑菇肥可增大土壤盐基饱和度 ,提高冬季草坪质量。施堆肥可提高土壤阳离子交换量和速效养分含量 ,但草坪均匀度和冬季质量下降 ,应减量使用。
The soil characteristics and turf quality on manilagrass (Zoysia matrella) under two organic fertilizers were studied in the subtropical region/lateritic red earth, The result shows: ① Two organic maters both improved soil infiltration/water capacity. ② pH value were decreased and enhanced with organic maters one year later. ③ Mushroom debris enhanced base saturate rate, and made a better quality of winter turf. ④ Compost enhanced cation exchange capacity and available nutrion greatly whitch made poor uniformity and quality of winter turf, so it should be used in low level.
