Tree species winter storage 9 attention

To ensure safe winterization of tree species and ensure germination rate, different storage methods must be adopted according to the physiological characteristics of various tree species. Storage seeds should pay attention to the following 9 aspects:
Pay attention to the high temperature: As the temperature rises, the respiration of the seed also increases, and it is easily damaged when the seed temperature exceeds 40 degrees Celsius.
Pay attention to moisture: The higher the seed moisture content, the greater the respiratory intensity, the more nutrients are consumed, and the weaker the seeds are.
Note that smoke: long-term smoked seeds will not only reduce the germination rate and germination potential, but also cause the incidence of spring seedlings in the following spring.
Pay attention to harmful gases: pesticides and fertilizers must be stored separately from the seeds.
Note Steam: Do not store seed in a large steam room.
Be careful not to touch the ground: No matter you use a sack, cloth bag or other containers to hold the seeds, you can't put it directly on the ground to prevent the seeds from getting damp.
Pay attention not to use plastic bags to pack seeds: plastic bags are not airtight, which will cause the seeds to stop breathing when they are deprived of oxygen and reduce the germination rate. At the same time, it will also cause the seeds with larger water content to become moldy and deteriorate.
Take precautions to avoid sudden heat: If seeds are kept outdoors for a long time, do not go to the warm house again; otherwise, seeds that have been stored in the warm room for a long time should not be taken outside.
Take precautions against rain and snow: Store seeds outdoors. Do not allow rain and snow to get wet.
