The basic principle and application advantages of the root analysis system
The analysis history of the root system is also relatively long-term. Under such a state, root research methods have also been summarized. From the beginning of the root research science to the present use of scientific computer technology, the analysis of the root system has not changed, but only the analysis has changed. Tool of. The application of modern root analysis system makes the analysis process more precise and comprehensive. Because the root system is the underground vegetative organ of the crop, it not only absorbs the water and nutrients in the soil, but also fixes the plants. It is also a place for the synthesis and transformation of trace active substances such as amino acids and hormones. For the roots of the analysis of the history if it is also a thick historical data, in 1923 the United States vegetative ecologist Weaver first classic mining methods for root research, since then crop root research has gradually started, but the progress is slow. Since the 1980s, with the strengthening of people’s understanding of the importance of root systems and the continuous improvement of research methods and techniques, significant progress has been made in crop root research. The basic principle of the root analysis system is to combine the scanning system with the graphic analysis software. The image analysis software is used to analyze the root image of the scan, and the root length, surface area, volume, and number of root tips are calculated. Among them, the RootVizFS system can take all-round photographs of the root stereoscopic X-ray images. It is a non-destructive in-situ analysis system and is very suitable for studying the dynamic response of plant roots to stress. The application of the root analysis system has reduced the difficulty for the researchers to obtain the root parameters, but the high accuracy and dynamic monitoring of the whole root system of field plants is still difficult to achieve.
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.

1. Look at the hue and surface roughness of the edge banding strip. The color of the surface of a good edge banding strip is also very important. Whether the color is close to the customized product and is gorgeous. If the surface is very rough and there are pull marks, the quality is definitely not much better. This is the surface quality of the edge banding strip. It has nothing to do with the quality of the inner material of the edge banding, mainly the production process of the edge banding factory and the production technical skills of the employees. A good edge banding strip is: the surface must be smooth, no blistering or seldom bubbling, no drawing or few drawing, moderate gloss, not too shiny or too matte (unless there are special requirements).
2. Check the flatness of the surface and bottom of the edge banding and whether the thickness is uniform, otherwise it will cause the joint between the edge band and the board, the glue line is too eye-catching or the gap between the board and the edge band is too large, which will affect the overall beauty. Details determine success or failure, and often a small detail problem may bring an embarrassing situation where the overall effect is not good.
3. Whether the edge trimming is whitish, whether the surface of the bent edge strip is severely whitish, and whether the ground color of the trimming strip is close to the surface color of the board in question. PVC Edge Banding strips are mainly made of PVC and Calcium Carbonate plus additives. If the calcium carbonate content is too high, whitening of the edge banding and bending will occur, which proves that the quality of such products is not good.
4. Whether the strength is okay and whether there is elasticity. High strength means good wear resistance, and the corresponding quality is better. Too high strength also means increased processing difficulty. Low elasticity means low wear resistance and low aging resistance. In addition, according to actual production needs, manual trimming is generally required, and soft spots can be made appropriately, and the automatic edge banding machine can make hard points appropriately.
5. Whether the adhesive is applied evenly and whether it is easy to fall off during use.
6. Smell whether the PVC edge banding strips taste or not. Products produced with good quality raw materials generally have a small taste. If the taste is too large, it means that the quality of the raw materials used in production is relatively poor.
