The crop varieties include rice, wheat, corn, soybean and other major food crops, economic horticultural crops such as cotton, rapeseed, and vegetables, as well as characteristic functional crops such as millet and barley. At present, in the development of agriculture to promote quality and efficiency, it cannot be ignored. One problem is the protection and utilization of crop germplasm resources. To build a library of crop germplasm resources is to use modern technology to maintain the “family†of crops, and to create greater possibilities for increasing the distribution of resources and promoting the efficient use of innovative germplasm and new technologies. The so-called germplasm resources of crops refer to resource materials related to agriculture that can be used for breeding or biological resource research. Crop germplasm resources are so important because they contain excellent genes that have not yet been developed, and the protection and research and development of these crop germplasm resources is crucial for national crop breeding and industrial development, and is related to national food security. . In view of the germplasm resources of crops, at this stage, on the one hand, it is necessary to strengthen the survey and collection of crop germplasm resources. On the other hand, it is necessary to strengthen the information management of crop germplasm resources so that the subsequent development and utilization can be better, so the crop germplasm The resource pool bears two important responsibilities for protection and utilization. The crop germplasm resource pool provides modern environmental conditions for the long-term preservation of crop germplasm resources by using modern technology, prolonging the preservation time of germplasm resources, and improving its preservation quality. At the same time, using information technology to further improve the informationization of germplasm resources. The management system is more conducive to the sharing and utilization of germplasm resources and promotes the development of China's breeding industry. Therefore, the construction and application of crop germplasm resources pool is of great significance for realizing the protection and sustainable sharing of germplasm resources and comprehensively improving the scientific and technological innovation capability and core competitiveness of seed industry. In normal production, this part of the wax can be directly added to the polyolefin processing as an additive, which can increase the gloss and processability of the product. As a lubricant, polyethylene wax (PE wax) has stable chemical properties and good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl acetate, ethylene-propylene rubber and butyl rubber. It can improve the fluidity of polyethylene, polypropylene and ABS and the release properties of polymethyl methacrylate and polycarbonate. Compared with PVC and other external lubricants, polyethylene wax has a stronger internal lubricating effect.
