Small packaged seeds should control moisture
Before the seeds are packaged, they must be dried and the moisture should be reduced below the safe moisture level. Rice and maize varieties should be controlled below 13%, while seeds with higher oil content, such as oilseed rape, peanuts, sesame seeds, cotton, etc., must be reduced to 8% to 10%. The author chose the Shandan No. 4 produced that year. 13%, 14%, 15%, and 16% of corn seeds with 4 different water contents were 5 kg each, and then stored in the room at room temperature. The first germination test was performed at the time of storage, the second test was performed 180 days later, and the third test was performed 365 days later. If the seed moisture content is below 13%, the seed oxygen is weak, limiting the activation of the seed enzyme, so that the seed is in normal dormancy. When the moisture content of the seeds exceeds 14%, the oxygen absorption of the seeds is enhanced, and the respiration intensity of the seeds also increases as the moisture content of the seeds increases. In the packaging bag, it will cause an anaerobic metabolism and produce a large amount of harmful gas inside the bag, causing the embryo to suffocate and die.
Small package seeds should be carefully selected to remove impurities, empty grains
Generally, there are some differences in the seeds that have just been acquired. Before the packaging, it should undergo a rigorous selection and grading process to remove empty pods, destroy grains, insect pods and various impurities. When the standards are basically the same, they are mixed and mixed. Otherwise, the quality of seeds will be affected. For example, if the seed with low purity is mixed in the seed pile with high purity, it will not only reduce the use value of the latter in production, but also It will affect the stability of the seeds during storage. Seeds with low purity tend to absorb moisture and cause moisture transfer in the seed heap, causing the seed to lose its usefulness.
Small package seeds should do 4 "not packaged"
One is that different crops and different varieties can not be packaged; the other is that when moisture exceeds the standard, they cannot be packaged; third, there are insect-imposed seeds that cannot be packaged; fourth, the seeds whose purity is not up to standard cannot be packaged; and the fifth, new and old Chen seeds are to be packaged separately.
Small package seeds should be stacked
After being packed in the warehouse, the stacking should be 50 cm from the wall and 60 cm apart from the malleolus. The stack height and width depend on the degree of seed drying. Seeds with higher moisture content should be lower and narrower to facilitate ventilation. Dry seeds can be higher and wider. The stacking direction should be parallel to the doors and windows, and ventilation will facilitate the circulation of air. Small packaged seeds should be protected against insects, mold, and rodents.
