水土保持优势植物生长的分析研究
- Title:
- Analysis and Study on Vegetation Growth in Soil and Water Conservation
- Keywords:
- soil and water conservation; vegetation growth; biodiversity
- 摘要:
- 在第四纪红粘土水土流失区水土保持坡面绿化实践中。总结出实现生物多样性的植物群落组合系列。主要有刺槐-胡枝子-百喜草系列；柏木-紫穗槐-长叶画眉草系列；木荷-胡枝子-假俭草系列；樟-多花木兰-百喜草系列；枫香-胡枝子-百喜草系列等。生物多样性群体的建立有利于增大环境容量，抑制植物虫害发生和缓解植物的早衰现象发生。利用优选植物种实现土壤流失坡面绿化，必须采用正确的实施方法，而公顷施750～1125kg钙镁磷肥是不可缺少的。
- Abstract:
- In the practice of soil and water conservation on soil loss region with quaternary red clay patent,some series of vegetation community realizing biodiversity have been concluded.There are mainly as follows:Locus-laspedeza bicolor-bashia grass;Cypress-amorpha fruticosa-eragrostis clongata Schima suberba-laspedeza bicolor-erichloa ophiuroides;Camphor tree-magnolia-bashia grass;chinese sweet gum-laspedeza bicolor-bashia grass,etc..The establishment of the vegetation community with biodiversity is to the advantage of enlargement of environment capacity, curb of vegetation disease and insect attack and alleviation of vegetation pre-decline phenomenon.Using optimization of varieties for restoring vegetation coverage,the eroded slope surface could be greened with application of 750-1 125kg/hm2 Ca-Mg-P-fertilizer.
