Avoid using plastic bags because the plastic bags are not air-tight. Under hypoxic conditions, the seeds undergo anaerobic respiration and produce a large amount of toxic substances, which can kill the embryos, or the moisture and heat generated by the respiration of the seeds cannot be dissipated. The seeds become hot and mildew but do not germinate. Avoid contact with the ground. The ground has high humidity. In order to prevent the seeds from getting damp and reduce the germination rate, regardless of sack, cloth bag and other containers, they should not be directly stacked on the ground. Use bricks or wooden boards to raise them about 50 cm. Avoid high temperature. As the temperature of the seed increases, its respiration also increases. When the temperature inside the seed exceeds 40°C, it is easily damaged. Avoid smoking smoke contains a lot of carbon dioxide and other toxic substances. After long-term smoking, the seeds will reduce their viability. Even after the emergence of the seedlings, the growth is weak and easy to get sick. Avoid mixing with pesticides and fertilizers. Most of pesticides and fertilizers are volatile and corrosive. If they are stored in the same room with seeds, some toxic gases emitted by pesticides and fertilizers will cause seed poisoning and reduce the germination rate of seeds. Avoid high water content The higher the water content of the seed, the greater the respiratory intensity, and the correspondingly more nutrients are consumed, resulting in weaker seedling emergence after sowing. Avoid sudden cold and sudden heat. Sudden cold and heat can easily lead to physiological disorders of the seeds. Therefore, if the seeds are stored outdoors, they should not be transferred to the warm room after being frozen; the seeds in the warm room should not be frozen outside. .

Avoid moth-eaten seeds during the storage period, they will be eaten by a variety of pests. The way to avoid them is to dry the seeds as much as possible to create unfavorable living conditions for pests. You can use sun exposure at noon on a sunny day to eliminate pests.
Avoid mixed seeds, label them in time after harvest, indicate the variety and harvest date, and avoid mixing.
