Effects of Nitrogen Application and Cattle Manure Addition on Vegetation Restoration in Coal Mine Replanting Area
摘要
Abstract
Fertilization is an effective measure to increase soil nutrients and promote vegetation recovery in coal mine waste land.To investigate the effects of nitrogen application and cattle manure addition on plants in coal mine replanting areas,this experiment took coal mine replanting grassland was as the research object,and used a split-zone experimental design to set up 5 nitrogen fertilizer levels including 0(CK),5(N1),10(N2),20(N3),30 g·m-2(N4)and 2 modes of cattle manure addition including 0 and 300 g·m-2.By analyzing the effects of nitrogen application and cattle manure addition on the height,cover,density and biomass of grassland vegetation in coal mine replanting,the restoration effect of grassland vegetation in coal mine replanting area under the measures of increasing nitrogen fertilizer and cattle manure was investigated.The results showed that nitrogen application had a greater effect on vegetation cover and biomass,and compared with CK,N1 treatment increased vegetation cover by 1.14%,28.57%and 63.64%in June,July and September,and plant biomass increased by 14.45%,14.29%and 24.46%,respectively.Whereas,the N4 treatment decreased the vegetation cover by 44.32%,72.86%,13.64%in June,July and September,and the biomass by 36.11%and 41.43%in June and July.Addition of cattle manure had a greater effect on the mean height of vegetation,and N4 treatment reduced the mean height of vegetation by 16.40%and 35.05%compared with CK in June and July.In addition,in terms of fertiliser application on phyto-economic taxa,the fertiliser pattern of nitrogen application+cattle manure was more beneficial to the growth of graminaceous plants and increased the biomass and density of graminaceous plants in the community.In conclusion,the addition of cattle manure could enhance the average height of plants,and the application of nitrogen fertiliser 5 g·m-2 was beneficial for the recovery of vegetation cover and biomass in this type of coal mine replanted grassland,while the application of fertiliser 30 g·m-2 could have adverse effects on plants.Above results provided scientific basis for carrying out ecological restoration work in this type of abandoned mines.关键词
