The prominent problem of corn seed storage in northern China is that the seed temperature is low at the late stage of maturity, and the seed moisture is high at the time of harvest, and it is difficult to be dried and susceptible to low-temperature freezing damage. Therefore, how to safely live through winter is the key point for storage and management of northern corn seed. According to the research results and practical experience, from the pre-harvest start, using the cool and dry climatic conditions in autumn in the north, the key factor of drying seed precipitation is to be taken. Before the low temperature arrives, the moisture is reduced below the critical moisture that is affected by freezing, and it can safely overwinter. The specific measures are as follows: (a) stand stalks, before the precipitation Between the end of the seedling ripening period and the wax ripening stage, the temporal lobe of the corn ear is opened and the ear is exposed to the air, which can receive a significant precipitation effect. This measure has become a widely used method for drying corn seed in Liaoning, Jilin and other provinces. Moulting time is performed in the middle of September and 10 to 20 days before harvest. Tests showed that the amount of precipitable water in the first 20 days before harvest was 9.7% higher than that in the control, and that in the first 15 days before the harvest was 8.6%, while that in the first 9 days was 6.5%. The most suitable time for standing stalk stalks is the early stage of seed waxing, which will affect the output too early. If it is too late, the precipitation is not obvious and it is not worth the candle. Station stalk moulting is particularly suitable for those with a long growing period, live stalk maturation and slower dehydration of the combination. (B) Early harvest in due course, sorghum drying The viability of corn seeds formed earlier. Experiments have shown that corn seed at the end of milk-mature stage has good seed quality and is a critical period for early harvest, and wax harvesting is ideal, not only has high vitality, but also does not affect yield. The specific practice of sorghum drying is to take the father first and cut off the father from 30cm above the ground. After the mother cuts from the ground, the crowbars are tied and 2 to 4 strings are hung on the parent's sorghum for drying. (three) corn ear ventilation storage Due to the large porosity during storage of corn ear, it is easy to ventilate and dry, and can continue to reduce the seed moisture in autumn and winter, and the cob has a certain protective effect on the embryo, which can reduce the infection of mold and worms. There are many ways to store the ear of corn for ventilation. According to the size of the seed, it can be used flexibly. A small amount of seeds can be used for stakes, wooden frames, hanging in the shed, etc. When the amount of seeds is large, it is possible to choose a high-drying, well-ventilated place to erect maize ear positions perpendicular to the main wind direction in the fall. The specific method is to lay the bottom of the floor with bricks, wood, etc. at a height of 30 to 50 cm, and lay a straw, Masonry corn warehouse above, the warehouse thickness 70 ~ 100cm, height and length depending on the amount of seed can also be built into multiple rows of warehouses, but each row should have a certain distance between, in order to avoid mutual wind. In order to facilitate the erection of a ventilation bin, some places will put the ear of corn into a well-ventilated woven bag first, and then build a warehouse, which works well. Conditional units can also build permanent corn warehouses: use square wood for fixing columns, place 30 to 50 cm on the floor, store the bottom of the warehouse, use wooden slats or metal to form a ventilation silo wall, and cover with a person's arm. The rain (snow) shed is both airy and protected from rain. Corn pickers should be selected when picking, picking the unripe and high-water spikes to continue drying. When the seed moisture drops below 20%, it can be stored in the warehouse without having to be dumped. It has been stored until spring sowing and threshing. The seed bank can also be stored when the seed moisture falls below 16% before winter. (D) Low-temperature sealed storage for another year The ear of maize in a ventilated bin can reduce the moisture content to about 13% in the spring, and if it is not used for sowing in the current year, it is best to carry out sealed storage after threshing. The method is to thresh in the early spring (from March to April), and then the natural low-temperature over-dried winds are used for closed storage to keep the seeds dry and stored at low temperatures. Sealing can be done by means of glands, sleeves, etc. Insulation materials are better for expanding perlite, and substitute materials with lower bulk density such as rice husk also have a certain effect. The thickness of the isolation layer is preferably 20-40 cm, and the integrity of the sealed thermal insulation layer is taken into consideration. In the storage management must pay attention to the following points: 1. Strict control of moisture to prevent frost damage The quality of seed storage depends largely on the seed moisture content. Low temperature is an advantageous condition for seed storage, but before the cold weather in the north arrives, seeds can only be fully dried to prevent freezing damage. In people's warehouses and during storage, the water content must always be kept below 14%, and the seeds can be safely wintered. If the moisture content of corn seeds is too high, various enzymes in the seeds will be metabolized and the respiratory capacity will be strengthened. Under severe cold conditions, the seeds will freeze damage and reduce or lose the ability to germinate. According to relevant data, when the moisture content of corn seeds is less than 14%, the outdoor temperature does not reduce the germination rate below -40°C; when the water content is 19%, the outdoor temperature is -12 to -18°C. Under the conditions, the germination power was lost only after 8 days. When the water content was 30%, only 2 days later, all of them were frozen to death under the same outdoor temperature. 2. Strengthen seed management Regular inspection of water content, germination rate Northern corn seeds have a longer winter storage time. Therefore, check the seed moisture regularly during storage. If it is found that the moisture exceeds safe storage standards, it should be ventilated and ventilated in time to adjust the temperature and humidity so as to prevent the seeds from freezing or mildew. In addition, seed germination tests should be conducted periodically to check whether the seeds are damaged. If the germination rate is reduced, the cause should be identified and remedial measures should be taken promptly. 3. Create a good storage environment for warehouses that do not meet the standards and conditions of poor construction to maintain, the seed warehouse to do a clean and clean inside and outside the library, the warehouse does not leak rain and snow. Outdoor storage can not be stored in the open air where rain and snow leaching. We must also do a good job of pest control and rat-proof work. 4. Reasonable storage and storage methods are reasonable, and directly affect the storage effect. There are several storage methods, such as outdoor, cold room, and warm room storage. If the seed moisture content is below 14%, indoor and outdoor wintering is safe. However, it is generally better to store in a cold room, but it can also be stored outdoors, but care should be taken to prevent rain and snow from leaching. Regardless of the method used for storage, the seed bag should be placed more than 30cm above the ground, leaving a certain gap between the stacks. It should also be noted that seed stored outdoors should not be transferred to indoor after being cooled; seeds that are also stored indoors should not be suddenly transferred to the outdoors. Otherwise, sudden temperature changes will reduce the germination rate of the seeds.
