- 摘要:
- 为探索改善沙区沙化土壤的理化性状和肥力状况、促进植物优良生长。应用特定生产工艺将天然黏土矿物、城市生活污水和污泥按一定比例加工成自制天然环保型土壤改良剂（简称环保型土壤改良剂），并采用正交试验设计盆栽法，以沙区主要造林树种紫穗槐、白榆、欧美杨108和沙柳为研究对象，通过观测植物叶片叶绿素含量和光合作用特性，研究了不同环保型土壤改良剂的应用效果。结果表明：在提高植物叶绿素含量方面，以沙柳、环保型土壤改良剂③、矿物添加量150 g、污泥添加量250 g组合效果最佳；在增强植物光合速率方面，以欧美杨108、环保型土壤改良剂①、矿物添加量250 g、污泥添加量200 g组合效果最好。该研究对我国北方干旱半干旱地区改良沙化土壤理化性质、提高植被覆盖率具有非常重要的意义。
- Abstract:
- To explore the way to improve the physical and chemical properties, fertility status of sandy soil and promote vegetation growth excellently, this study focused on the self-made natural environment-friendly soil conditioner which was processed with natural clay minerals, municipal sewage and sludge by a certain percentage through specific production craft through pot culture method using orthogonal experimental design, and using the Amorpha fruticosa, Ulmus laevis, Populus canadensis Moench 108 and Salix psammophila for object of study, which were main afforestation tree species in North China. By observing leaf chlorophyll content and photosynthetic characteristics of the species, the application effect of environment-friendly soil conditioner was tested. The results showed that in terms of increasing chlorophyll content, the best outcome was the group of Salix psammophila, environment-friendly soil conditioner③, mineral additive amount of 150 g and sludge additive amount of 250 g; with regard to increasing photosynthetic rate, the best outcome was the group of Populus canadensis Moench 108, environment-friendly soil conditioner①, mineral additive amount of 250 g and sludge additive amount of 200 g. Research has an extraordinary important significance on improving physical and chemical properties of sandy soil and making the vegetation coverage better in arid and semi-arid areas of north China.
