Cotton is a cross-pollination crop, and bio-mixing and mechanical intermixing are the main causes of the decrease in the purity of the varieties. In order to ensure seed purity, improve yield, and improve quality, it is required to realize the regeneration of original species in an ecological zone. Therefore, it should be The seed cotton produced in the Liangcai area will be single rolled. Generally, after the wool is lightly removed, the seeds will be stored separately when the water content is below 12%. For long-term storage of seeds, it is not appropriate to use sulphuric acid to remove the velvet first, and it is not recommended to use seed coater for storage after storage to prevent significant reduction in the germination rate during storage. The factor that affects the moisture content of seeds during storage is air humidity. When the amount of seeds is small and the relative humidity of the air is lower than 50%, the water content of the cottonseeds significantly decreases. When the relative humidity is 50 to 70%, the water content is stable. When the humidity is higher than 70%, the water content of the seeds increases significantly. In the northwest inland cotton and cotton areas in the Yellow River Basin, during the winter and spring months, there is not much precipitation, and the relative humidity is mostly below 65%. Small cotton seeds can be stored in sacks or sacks for storage or storage. When a large number of centralized storage, you can also cover in the open air moisture. The spring in the cotton region of the Yangtze River Basin has a lot of rainfall and the relative humidity is between 70 and 80%. The seed bank should have ventilation and moisture proof conditions, pay attention to ventilation and dehumidification, and turn over and reduce moisture.
There may be disputes about when humans began domesticating horses,
but there is no argument that horses have helped shape human history. We know Chinese equine Veterinary Medicine, including herbal
treatments and acupuncture, dates back thousands of years, but there`s
no agreement on the date, or even century. We do know the year their
health and care became part of the formal curriculum of veterinary
colleges. The year was 1761 and the location was the first veterinary
school in the world, in Lyon, France. Equine anatomy as part of a formal
curriculum has been studied by veterinarians since then, for more than
250 years.
