Winter storage of forest seed

Winter forest seed, if not kept properly, will affect the germination rate. As long as you pay attention to the following points, you can keep it well. 1, pay attention to temperature changes. As the temperature rises, the amount of respiration of the seeds also increases, and it is easily damaged when the seed temperature exceeds 40°C. 2, avoid excessive water. The higher the seed moisture content, the greater the respiratory intensity, the more nutrients are consumed, and the weaker the seed emergence. 3, to prevent smoke. The long-smoked seeds will not only reduce the germination rate and germination potential, but also cause the onset of seedlings in the spring of the following year. 4, avoid toxic gases. Avoid storage with volatile gases such as pesticides and chemical fertilizers. 5, to prevent steam. Can not be stored in a large steam room. 6, should not touch the ground. Whether sacks, bags or other containers are used to hold seeds, they should not be placed directly on the ground. They must be more than 40 cm above the ground to prevent the seeds from getting wet. 7. Do not use plastic bags for seeds. If the plastic bag is not ventilated, it will cause the seeds to stop breathing, and at the same time it will also cause moldy deterioration of the seeds with large moisture content. 8, do not suddenly freeze hot. If the seeds are stored outdoors, do not go to the warm room after freezing, and the seeds in the warm room should not be moved outdoors.
