The high moisture content of seeds and the cold climate are the main reasons for the freezing damage and germination rate of maize seeds in northern China. In winter 2002, this problem was particularly prominent. Therefore, appropriate seed drying techniques should be adopted according to local conditions. It is of great significance to ensure the quality of seeds, promote the efficiency of seed production enterprises, and increase the income of seed farmers. After years of practice, the drying techniques for corn seeds are summarized as follows:
1, field station stalk suede drying
The stand stalk mink period was in mid-September in Liaoning Province. When the mother's ear is in the wax ripening stage, the loquat leaves are peeled from top to bottom from the top of the ear, and must be peeled off in the end and cannot stay on top of the kernels. In order to prevent the recovery of the temporal lobe and the accumulation of water at the base of the ear, it is best to use a hemp rope or a leather sheath to bind and fix the temporal lobe so that the fruit is completely exposed.
2, field sorghum drying
While harvesting the ear, leave 2 rows every 4 to 6 female lines, cut off the corn stems, leave about 50 centimeters high, and then peel off the outer leaves of the ear, leaving 3-4 pieces inside. The loquat leaves will be bundled with 6 to 8 ears each, and they will be hung on the cymbals. The cymbals will be accompanied by the kinks and will be rotated once every 2 to 3 days.
3, the yard to hang drying
In the farmer's home, wooden sticks, iron wire and other materials are placed on a shelf, raised about 150 centimeters, and then 8 to 10 seeds are bundled into one, placed on a shelf, and rotated 2 to 3 days.
4, roof, drying field drying
The ears of clean eucalyptus leaves and filaments will be laid flat on the roof or in the drying field, and the drying shall be performed. The ears shall be evenly distributed, and they shall not be too thick. Turn them one or two times per day.
5, bag drying
The ears of clean leaves and filaments are neatly packed in mesh bags, and then evenly placed on a well-ventilated wall, wooden frame or roof, and turned in 2 to 3 days. Bagging ear should not be too much, too real, so as not to affect the drying effect.
6, hot air drying
In case of special years, if the seed moisture is persistently high, reaching about 20%, emergency measures such as fire pods, indoor storage or timely threshing, and drying should be taken to ensure safe precipitation of seeds.
7, pay attention to the problem
In addition to the drying of the field station stalks and sorghums, regardless of the type of drying method used, it is important to note that the drying area must be dry, ventilated, and equipped with rain-proof facilities. Do not store, bag or pile the fruit in the ear for long periods of time.
