The method of storage of corn seed in summer is as follows: The best time for drying and drying the seeds and drying the seeds is from the beginning of March to the end of April. If the seed stock is too large, it can be aired in advance according to the weather temperature. During the drying time, moisture does not reach the storage standard and can be turned three or four times a day. The weather with higher temperatures can be turned several times more quickly to accumulate precipitation. The seed pool temperature must not exceed 10 °C to ensure safe summer. Seeds inserted in the custody of the human bank are inserted into 3 to 5 thermometers, and are divided into upper, middle, lower, left, and right spots, and a 2 -dry-humidity meter is placed in the winter months. Beginning in April and ending in October. In July-September, it was tested once a day, every other month was tested once every 7 days, water was measured, buds were measured every half a month, and in order to ensure that the production was not affected by insect pests, the inventory was planted twice a year for aluminum phosphide. The library and time were closed fumigation before June 10 and August 10 respectively. Closed time is generally 5 days - 7 days. At the same time, in the middle and late July, we should pour it once to prevent excessive pressure on the maggots. After germination, the seeds will have poor germination rate and the germination rate will decrease. If the temperature in the kiln is too high, it can be ventilated with a blower. The stock seed is placed in the stock seed yard, and the bottom must be lifted from 35 cm to 40 cm, 10 sacks high, and between 1 metre and 1.5 meters wide between the rake and the larvae. The ventilation and sidewalks should not be mixed together. One must have the number and quantity of signs, labels, and plaques. The bottom of the library must be kept above 40 cm. Use a mat to make it. Each bucket should not be more than 10 sacks. When it is closed, use two layers of mats. Use three layers of mat on top and put one in the middle. Plastic rain protection.
