环保型土壤改良剂对沙区植物叶绿素和光合速率的影响
Influences of Environment-friendly Soil Conditioner on Chlorophyll and Photosynthetic Rate of Sand Plants
摘要
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.关键词
