Seed is the most basic agricultural production data, it is the internal cause of agricultural production increase, and it is the carrier of various technical measures. Therefore, the safe wintering storage of crop seeds is a key link in agricultural production and an important part of the rural winter and spring season. If there is a lack of necessary knowledge and poor management, the harm to pests will be severe, leading to a decrease in the viability of seeds and a reduction in the number of seeds. In severe cases, the seeds will be rotten and the agricultural production will be greatly damaged. Here are the storage methods for several major crop seeds:

One, corn

1. Ear storage

This is a kind of storage method that is both economical and effective. This method is conducive to seed ripening and drying, reducing the risk of worms and microorganisms, but the utilization rate is low. Specific practice: In the dry and cold winter season, corn stalks are prepared in the open field with sorghum stalks, and the ear is stored for winter. Or leave the seeds of autumn corn hanging. Suitable for small storage in farmhouses. However, this method should not be used in areas with high temperature and high humidity, because in such environmental conditions, corn is easy to absorb moisture and rejuvenate. It is necessary to adopt dry, low-temperature and closed storage methods.

2. Grain storage

If the amount of seed storage is large, this method is often used. The key is to reduce the seed moisture content to below 13%. After threshing, the corn was sun dried and stored in sealed warehouses. During storage, strengthen inspections of temperature, moisture, and insect pests. Once fever, mildew, sweating, condensation, budding, and worms are found, take timely measures. At the same time, according to the weather and seed storage conditions, timely ventilation and ventilation, if necessary, but also to dry and dry.

Second, wheat

1. Hot storage

This is a storage method that uses the heat-resistance characteristics of wheat, and has a good effect on insecticide and promotion of seed ripening. The method is simple and not limited by the number of seeds. Specific practice: In sunny weather, expose the seeds of wheat to a moisture content below 12%, and the seed temperature exceeds 46°C but does not exceed 52°C for two hours, and then the seeds are put into storage immediately after the heat is poured. And covered sacks 2 to 3 layers of closed insulation, so that the temperature is maintained at 44 ~ 47 °C, after 7 to 10 days after the sack was lifted, ventilation and temperature until the same warehouse temperature, and then sealed storage.

2. Pottery or altar storage method

This storage method is suitable for the storage of a small amount of wheat seeds in farms. After the cylinder or the altar is washed, disinfected and dried, a certain amount of hay wood ash is put in the bottom of the cylinder, and the seed and ash are separated by kraft paper. Newspapers, newspapers and then covered with about 10 cm thick hay gray, and then cover and seal. Prevent moisture and insects during storage.

Third, rice

1. Warehouse storage

This method requires seed moisture content below 14%. Before the storage, the library is first padded with plates, a layer of grass curtains is laid on the plates, and then the seeds are put into the seeds. The seed can be covered with straw. It is required that the temperature of the warehouse be maintained in a stable state to avoid hot and cold.

2. Cellar method

This method, because seeds are isolated from the outside world and has little change in temperature and humidity, is not only suitable for storage of rice varieties with good maturity and low water content, but also suitable for seeds with slightly poor ripeness and slightly higher water content. The specific approach is as follows: Select a high dry place, dig rectangular cellar, cellar depth 1.5 to 2 meters, width no more than 2 meters, the cellar floor and around the paved grass curtains, and then covered with mats, the rice seeds into the The rice seeds are covered with mats and covered with 30 to 60 centimeters of soil. At about the beginning of November, the seeds enter the pit. In April of the next year, when the temperature reaches 0 to 2 °C, the seeds are removed. After the temperature rises in the spring, dry it in time to prevent the seeds from deteriorating.

Fourth, soybean

Due to the poor thermal conductivity of soybeans and the tendency to change at high temperatures, low-temperature sealed storage methods should be used. Specific approach: Soybean threshing, timely drying air, control the seed moisture content below 12%. After drying, spread the cooling first, and then batch storage. In addition to closed doors and windows, the cleaned and disinfected grasshoppers or sacks can also be covered on top of the bulk seed piles. The glands should be smooth, tight and solid. This method can prevent moisture and insects. About 3 to 4 weeks after storage, it is necessary to timely carry out the ventilation of the warehouse and disperse the wet, filter and remove impurities, in order to prevent the occurrence of abnormal conditions such as sweating fever, mildew, and redness. For the farmers to store a small amount of seeds, glazed pots, cans or wooden boxes and the like can be used. The lower part and the upper part are covered with some grass ash or dry sand and sealed again. The storage period is mainly closed, but attention should be paid to timely ventilation.

Five, sorghum, millet

Before the seeds are put into storage, they must be selected to remove impurities and batches. The specific method is as follows:

1. Ear storage method

When cutting in the field, leave about 30 centimeters long stems, bundle them into small bundles, and hang them in the warehouse after drying.

2. Grain storage method

The seeds that have been threshed should be fully air-dried so that the moisture content falls within a safe moisture content (sorghum: 13% or less; millet: 12.5% ​​or less) and storage at a low temperature. If the seed temperature is below 25°C, it can be safely stored. If the seed temperature exceeds 25°C, the seed moisture should be properly reduced. When the seeds are in storage, if the temperature drops during the season, ventilation should be used to reduce the temperature to prevent condensation. Pay attention to check the moisture and heat of seeds during storage.

Sixth, cotton

Cotton seed shells are hard, with a layer of short fluff on the surface, such as large piles of storage, piles closed, short fluff moisture absorption, due to different periods of harvest, maturity, moisture content is different, therefore, to be separated from the flower before frost and after frost, Stored separately after the tie, it is best to spend the cream before flowering. The seed is fully dried, the water content is below 12%, and the height of the seed pile is controlled. Half-warehouse is suitable for ventilation. The thermometer is buried in the probe or embedded in the hole with a hole every 3 meters in the bamboo basket. measuring.

In addition, during the storage of seeds, new and old seeds cannot be stored together. Seeds of different crops must be prevented from mixing together. They must not be mixed with chemical fertilizers and pesticides. During storage, relatively constant temperature and humidity must be maintained. Management must be strengthened, periodic inspections must be conducted to identify problems. Take timely measures to resolve them.
