Experiment And Application Of Frisol For Vegetation Restores Of The Difficult Sites In Yulin Desert Region

FRISOL is a new material from Germany which used for environment engineering construction and the farming and forestry production,it is one series of fertilizer had liquid, solid and the textile fiber states and the prevention soil erosion's biological organic solidifying medicinal preparation and an environmental protection product.It is divided into four types: FRISOL A,F,S,Ef.Through to different difficult conditions of desert regions in Yulin local growth under splendid standing grain(frisol) serial products experiment and proved that not only the splendid standing grain may enhance the soil fertility effectively,increases the soil nutrient, stimulation soil beneficial microflora's activeness,the soil conditioning,simultaneously may prevent the soil sheet erosion effectively,reduces the soil moisture and the nutrient outflow, raises the afforested survival rate,promote plant growth,formate the high quality vegetation's fast growth.Discussed the best amount of formula under different conditions.road side slope:400gF+40gS+40gEf/m~2On sandy clope of the railway:200gF+100gA+20gS+30Ef/m~2Coverage sandy of coal mine:200gF+100gA+15gS+50gEf/m~2Flower Nursery cultivation:200gF/m~2Lawn rejuvenation:200gF/m~2Using FRISOL can raise 6-10%survival rate of trees species(Vary of species).The annual high-growth tree(take evergreen tree as example) may enhance 2-3cm,the bush may enhance 20-40cm,the lawn plant may enhance 9-15cm,wild herb class plant approximately above 50cm.In sand afforestation aspect,FRISOL has obvious solid Sha Hekang the sand to bury the function;Has certain anti-wind erosion,the water erosion in the roadbed side slope,maintains the soil erosion the function;In the mining area gangue duplicate draws back the afforestation, may make the vegetation to restore rapidly,achieves the government goal.The splendid standing grain to plants the species obviously the function effect is the herb respectively,next is the bush,the tree because of its own growth characteristic,when annual growth,although only differs between 2-3cm,but its growth quantity approximately enhances about 10-15cm during the following year.The long-duration of FRISOL on the role of the growth of plant species which it can not have a clear-cut conclusion,it also remains to be follow-up test.As far as is known,it should not be used on the cutting propagation of seedlings.
