Soil to Facilitate the change of Soil particle size in Granitic Gneiss Mountain area of North China
Soil degradation very serious in North China granitic gneiss mountains area. the limiting factor in vegetation recovery is poorly soil environment. In the study, four kinds of land preparation methods and the three kinds of new fertilizer treatments had led to soil degradation with facilitate technology, The results showed: that different land preparation methods and different treatments on soil contributed to Imm in diameter smaller than the weight of soil particles. the performance of the blasting site preparation>cave-like site preparation>wing fish-scale pit> fish-scale pit, and each land preparation methods in the fertilization treatment to organic fertilizer (YJ) was most obvious; with three kinds of new fertilizer increased the weight of soil particle size less than Imm change in different degrees. Which release fertilizers to release fertilizer 200g/point) (HK4) 4and 300g/point (HK5) the most significant treatment effect; the best bio-organic treatment effect to fertilizer 2000g/Points (YJ3); microbial fertilizer the best effect to microbial fertilizer 150 g/point (SW3). The above description of several facilitate technologies have had an impact on soil degradation, because great advantage from the degradation of soil particle size is increased towards the small size of soil particles aspects of evolution. Soil degradation contribute to the best facilitate technology for the Explosive Technique+Organic Fertilizer.
