First, the drying of vegetable seeds must be fully aired and precipitation before drying. The moisture content of seeds is an important factor in whether seeds can be stored and used for a longer period of time. Seed if the water content is small, its own respiration and physiological activity will be inhibited, so that the seeds can be stored safely and increase stability. The freshly-harvested seeds have been air-dried during the harvesting and threshing process. However, due to factors such as short time and rainy days, the water content does not necessarily fall below the safe water content. Therefore, it is necessary to select several eye-catching winds. The weather is fully aired so that the water content is below safe water.
The moisture content of common wind crops is as follows: 7%-12% of tomatoes, 7%-11% of cabbage, 10%-12% of kidney beans, and 7%-11% of eggplant. The drying of seeds can be performed by natural drying method. That is, the seeds after picking are spread on the curtains or mats to dry and are turned once every other time. This can accelerate the evaporation of water and achieve safe storage of water.
Second, the selection of vegetable seeds of various vegetable seeds, must be selected before processing to improve the clarity of the seeds. A screening method can be adopted, that is, selecting suitable types of round holes or long-hole sieves to remove straw, sediment, pods and impurities, and removing rind, leaves, and light-weight dried seeds. After the screening, a further selection of the seed's clarity should be carried out. This can increase the seed germination rate. We can use the seed clarity table to observe the seed's appearance and lesions.
Third, the storage of vegetable seeds for safe storage has important significance for the germination rate and sowing quality of vegetable seeds. Several vegetable seed storage methods:
1. Bundle or pruning Storage Bundles the vegetables seeds that are to be harvested, hang them in a cool, ventilated place, and pick and thresh when they are used.
2. The bag storage method puts the harvested vegetable seeds in a kraft paper bag or cloth pocket, and is placed in a dry and ventilated place and taken out when it is used.
3. High-hanging storage method After the seeds are dried thoroughly, they are sewn into small cloth bags and filled with gauze. In this way, the permeability is enhanced and seeds can be breathed to ensure seed quality. In addition, under the ventilation and cool roof of the cloth bag, it is not easy to make the seeds damp and deteriorate.
4. Stored under low temperature, dry, vacuum conditions 1 can be placed in plastic paper bags with anti-corrosive coating.
2 sealed storage. To select pottery jars with better sealing properties, wash and dry them, put a small amount of quicklime on them, lay a layer of paper on top of the lime, then pour the seeds inside and cover the lime in the altar. In this way, both the humidity and seed oxygen can be supplied. This method can be stored for more than 2-3 years, and its rate can still reach 95% or more.
5. Several issues that should be noted 1. Use sacks, woven bags, cloth bags and other packaging seeds, do not use plastic bags.
2. Keep seeds in the dry, dry place and avoid entering a closed, damp warehouse. Raise the height of the ground with a brick or roundwood by 30 cm or more, and keep it away from the wall by about 30 cm. Avoid moisture and damage the seeds.
3. Vegetable seeds should be stored separately from pesticides, fertilizers, etc.
4. Store the seeds away from the stove to prevent the smoke from fumigating.
5. Strengthen pest control to ensure seed quality.
6. Seeds deposited outdoors are protected from rain and snow. At the same time, attention should be paid to the prevention of rodent damage and the use of markings inside and outside the packaging bag to prevent mixing.
Whoever does the right protection measures to prevent the destruction of all seeds due to a momentary mistake.
How to make vegetable seeds safe for winter
How to make vegetable seeds safe for winter vegetables seed processing is to mix seeds with immature seeds, sclerotia, insects, weeds and other living impurities and straw, residual leaves, stones and other inanimate substances, through the processing to clear In addition, it is necessary to observe the appearance of the seeds to observe whether the lesions, etc., improve the quality of the seeds and the germination rate, achieve safe wintering, and reduce losses. We can accomplish this through three steps: air drying, selection, and storage. This can achieve the most general purpose and increase the seed germination rate.
