| The rocky slope in the northern mountain area of Tangshan is a special habitat,for the poor soil conditions.Based on Tangshan Luanzhou city in northern area chairs mountain rock slope as the research area,analyzed the climate conditions in the area,Tried to select vines,which are suitable for local growth test of fast-growing means with Boston ivy to attempt through the supply of water regulation and fertilizer as vines fast-growing covering technology research.Through field investigation and analytic hierarchy process,the planting of vine in the study area shows that parthenocissus was very suitable as fast-growing plants in this area due to their large coverage area,tolerance and growth speed.Through the two Boston ivy(parthenocissus,quinquefolia)of leaf number,plant height,plant stems and chlorophyll growth statistics and Pn,Gs,Cond,Tr,the results were statistically analyzed by correlation analysis,two ivy indicators of growth and photosynthetic indicators showed significant correlation,between each index has a strong affinity.The results of water regulation,base fertilizer selection,fertilizer selection and graphene enhanced foliar fertilizer were comprehensively analyzed by membership function analysis,and it was concluded that quinquefolia with 80% water and compound fertilizer,foliar spraying with nitrogen and potassium fertilizer with 15% concentration of graphene as synergist could have the best rapid growth effect,this type socred 0.696.Parthenocissus has a better rapid growth effect when water is 80%,urea is applied and potassium hydrogen diphosphate is sprayed on the leaves,this type socred 0.699.The research results can provide a certain technical reference for the rapid vegetation cover technology of the rocky slope in the northern mountain area of Tangshan,and provide the next research direction in the application of parthenopsis creeper in the effect of improving the efficiency of graphene.Figure 67;Table 23;Reference 78. |
