At present, grassland construction in the alpine pastoral areas in northwest Sichuan has entered a new stage of development. With the reform and implementation of the responsibility system for production, the entire trial animal husbandry industry has also witnessed a more rapid development. Grassland is aggravated, and the increase in natural grassland carrying capacity will inevitably cause changes in the composition of natural grasshopper systems and grassland plants. 'High quality, good palatability grass species and their establishment in grassland vegetation will therefore If you reduce, serious people will have the possibility of disappearing. Therefore, it is more urgent and necessary to take effective measures to protect the resources of collecting natural grass plants. In the artificial grassland animal husbandry production, in addition to strengthening the rational management and utilization of natural grassland based on the ecological and economic effects, the establishment of a germplasm resource bank to fully and effectively collect the pasture germplasm resources has the protection of economical pasture resources. Strengthening protection and preservation is an important part.
Due to the interference of practical reasons, the purpose of the establishment of the grass germplasm resource bank is very clear. This is mainly based on the protection of biological resources and the development of pasture resources. It can collect and preserve grassland resource materials with high economic value in the northwestern Sichuan grassland at one go. Depending on the needs of scientific research and plant production, research on the germplasm properties of resources is being carried out in succession to explore and develop useful germplasm to lay a rich germplasm foundation for the modern feed production in the livestock industry.
Germplasm resources play a very important role in plant genetics. For pastures, their germplasm includes wild types, closely related species, and artificially-selected varieties and strains. Research on their storage is an important measure for biological protection and utilization. . In countries with advanced agricultural production technology, great attention has been paid to the collection and conservation of plant germplasm resources. In 1982, the Chinese Academy of Agricultural Sciences established China's first germplasm resource bank. However, grass species that thrive under conditions of alpine grassland habitat have not been widely collected and conserved by relevant departments. With the development of grassland scientific research in the northwestern Sichuan grassland and its adjacent areas, how to properly protect and make full use of the forage resources in this area is the basic work that should be paid attention in the research of grass collection and breeding. Therefore, the establishment of a grassland germplasm resource bank in northwestern Sichuan should be mentioned on an extremely important agenda. With the increase of grassland planting area and the increase of grassland carrying capacity, some grassland degradation factors may cause the disappearance or reduction of some high-value grass species. Therefore, the collection and preservation of pasture germplasm resources should be carried out as soon as possible, which has the significance of protecting excellent grass species resources.
0. the density of adc12 and aluminium is 2.75g/cm^3
1. Aluminium Die Casting Lower costs compared to other processes.
2. Economical – typically production of any number of components from thousands to millions before requiring replacement is possible.
3. Castings with close dimensional control and good surface finish
4. Castings with thin walls, and therefore are lighter in weight
