The content of humic substance C in all groups of soils in the organic matter and chemical fertilizer areas has obviously increased, and very few increase in the content of the humic substances in the soil. The extent of their variation is that except organic fertilizers, active humic acid, and humin in the fertilizer area, a slight increase (2 to 12%), humic acid and fulvic acid are both slightly reduced (14 to 2%), and organic areas are organic. Both carbon and humic substance C increments were significantly higher in each group, and the increasing order of size between the components was active humic acid> humin> organic C> fulvic acid> humic acid.
The determination of the soil fertiliser detector found that, regardless of the application of fertilizer or organic fertilizer combined with chemical fertilizer, the content of soil organic C and humic substance C in each group increased, but the increment of single application of chemical fertilizer was very small. A substantial increase. It is worth noting that the accumulation of active humic acid in the soil of various organic matter areas, the increase rate of fulvic acid is significantly higher than humic acid (except wheat). This has important practical significance for the regulation of soil to provide the energy needed for crop growth. The increment of humin in all regions of organic matter is high, which provides a favorable material basis for the formation of a good structure of the soil.
Soil Fertilizer Tester in the determination of soil fertility applied to organic matter found that the effect of organic matter seems to be more obvious in their promotion in addition to their own stability and soil N compounds quickly converted into low-molecular compounds, further mineralized for plant absorption and utilization. Another important factor is that the supply of energy is more abundant than fertilizer. And this is important for the photosynthesis of crops and the accumulation of dry matter. In the case of organic matter, because they regulate the ratio of stable macromolecules and active low molecular compounds and mineralized substances in the process of decomposition and conversion of C and N compounds in soils, the reaction also differs in the benefit of increasing production. .
The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
PVC furniture edge banding is relatively light, which is relative to metal and plexiglass. The reason for the lightness is not because it is a polymer compound, but because they are organic compounds, which are composed of carbon, hydrogen, oxygen, and chlorine. And other lighter elements.
The material of pvc furniture edge banding is plastic, which is easy to process. Plastic has plasticity, that is, it deforms after heating or pressurizing, and maintains its original shape after the temperature drops or the pressure disappears. It can be processed into edge bands of their respective shapes by extrusion and other methods, such as T-shaped edge bands, H-shaped edge bands, D-shaped edge bands, V-shaped edge bands, I-shapes, and so on.
pvc furniture edge banding is of high quality and low price, and the price of plastic is far less than that of metal.
