摘要
根据草坪的外观质量、坪用质量和可持续生存能力等表现,在上海辰山植物园对日本结缕草和普通狗牙根两种主要草坪草进行土壤配比试验,探讨各配比的改良效果及新型改良剂的合理施用量。结果表明：配比3（原土∶沙土∶草炭∶MVP=4∶4∶1∶2）改良效果最佳,其不仅有效改善土壤的孔隙度、渗透性等物理性质,还显著提高草坪的综合质量,且不会影响地形稳定,适于辰山植物园比较丰富的地形结构。兼顾成本与改良效果,MVP的最佳使用量可以控制在10%~20%之间。
Japan Zoysia（Zoysia japonica）and Normal bermudagrass（Cynodon dactylon）are two major turfgrass colonization in Shanghai Chenshan Botanical Garden.According to the appearance quality,turf quality,and continued viability,the experiments of five soil ratio were done and the effect of amelioration of the rational application and the using amount of new modifiers were investigated.The results showed that the 3rd treatment which was made from soil,sand,peat and Turface MVP in the volume ratio of 4∶4∶1∶2improved the best,not only effectively improve soil porosity and permeability of physical properties,but also improved the overall quality of two kinds of turf-grass.In addition,The 3rd ratio didn＇t affect the terrain stability,which adapted Chenshan Botanical Garden＇s rich terrain structures.The optimal usage of Turface MVP can be controlled between 10%to 20%.
