基于生物炭联合甘蔗渣改性后的红黏土植物种植特性试验研究OA

Red clay soil,due to its low pH and insufficient nutrient conditions,can not meet the necessary require-ments for plant and microbial growth activities.However,after the modification by biochar combined with sugarcane bagasse,the physical and chemical indexes of soil have been effectively improved.In order to investigate whether the improved red clay soil can support normal plant growth,this study conducted an outdoor grass planting pot ex-periment using the modified red clay soil as the test soil.The dominant plant species for vegetation restoration on the modified soil were evaluated by planting vetiver,zoysia sinica,and bermuda grass.The results showed that veti-ver exhibited rapid germination and greater seedling height at the early stage,making it suitable for rapid soil stabi-lization and slope protection;zoysia sinica had a stable number of sprouts,making it appropriate for sites requiring high turf density;bermuda grass had a stable number of germination and strong environmental adaptability,making it suitable for growth in harsh or extensively managed areas.This study provides a reference for vegetation planting in red clay areas.
