How to store cotton seeds
The seed coat of cotton seeds is thick and hard, and is wrapped in linters. The heat conductivity is poor. It can be stored under low-temperature and dry conditions and its life span can reach more than 10 years. However, if the water and temperature are high, the respiration of the cotton seeds will be strengthened, not only eliminating nutrients, but also generating water and releasing heat, resulting in heat and mildew of the seed piles and reducing vitality. I. Preparation of Cotton Seeds before Storage 1. Preparation of cotton seeds. 1 Select full and mature pre-frost cotton seeds. The full and mature cotton seed coat has a dense and hard structure, and the external wax can prevent the influence of external temperature and humidity. The seed coat contains about 7.6% tannic acid, which has a certain antibacterial effect and good resistance to hiding. Immature cotton seeds are not resistant to storage. 2 Remove damaged grains, rotten grains, and pests and grains. 3 Strictly control the safe entry of cotton seeds: moisture does not exceed 11% to 12%, the netity is not less than 99.5%, and the germination rate is above 80%. One of these three indicators is unsatisfactory and it is a substandard cotton seed and cannot be stored in storage. 2. Preparation of the warehouse. 1 The warehouse should be inspected before use to determine whether the doors and windows of the warehouse are closed, whether the insulation and sealing effects are intact, and whether the instruments that monitor the temperature and humidity of the warehouse can work normally. 2 Clearance and Disinfection: Clearance not only removes all varieties of cotton seeds, impurities, garbage, etc. from the warehouse, but also cleans the warehouse tools, transportation pipelines, and removes weeds outside the warehouse; disinfection of empty warehouses can be treated with trichlorfon or dichlorvos. . II. Management of cotton seeds during storage 1. After the temperature check, after entering the winter, the moisture content is below 11%, check once every 5 to 10 days, and below 12%, check every day. The temperature check should be carried out regularly at different locations and different levels in the warehouse. 2. Ventilation and ventilation must be based on the temperature and relative humidity inside and outside the warehouse. When the outside temperature and humidity are lower than the inside of the warehouse, it is the best time for ventilation. At this time, ventilation can reduce the temperature and humidity; when the temperature outside the warehouse is the same as the temperature in the warehouse, and the humidity outside the warehouse is lower than the warehouse or warehouse. Internal and external humidity is basically the same, or when the temperature outside the warehouse is lower than the inside of the warehouse, it can be ventilated. The former is mainly scattered and the latter is mainly cooled. 3. Regularly check the quality of cotton seeds. During the storage period, the quality of the cotton seeds should be regularly checked so that the cotton seeds can be stored in a timely manner. The tests usually include the test of the cotton seed germination rate, the determination of the moisture content, the determination of the free fatty acid, and the determination of the fitness rate. If problems are found, they should be promptly resolved, such as enhanced ventilation.
