The storage method of the horse chestnut seed
The conker is a deciduous tree with a palmately compound leaf with long stalks, 5-7 leaflets, a petiole length of 5 cm to 10 cm, a petiole length of 6 cm to 10 cm, and sparsely pilose leaves along the veins. , With dust pollution prevention function, beautiful leaf shape. The flowers are large and white and are open from May to June. Because of its beautiful leaves, flowers, flowering seasons and other spring flowers staggered seasons bloom, Shuzi charm, soft material and many other advantages, has been favored by the people, has become a green family of visitors. Only seed propagation is currently used in A. chinensis. In order to better develop high-quality and robust seedlings, it is critical to store seeds well. The storage method is described as follows: First, preparation before storage: The collected seeds are piled in a cool and ventilated place, which is conducive to after-ripening and coloring, and has a certain effect on improving the quality of seeds and eroding their outer seed coat. Pay attention to the fact that don't pile up too high to avoid mildew. After 3 days to 4 days, the seed coats were peeled off and graded to select the inferior seed. After the threshing, the seeds have high moisture content and their physiological activities are quite vigorous. They should not be stored immediately. They should be placed in a cool and ventilated place. The thickness of the airing should not exceed 20 cm. The inspection should be repeated once a day and then stored 2 days to 3 days later. Second, the storage method: generally use the indoor sand method, sand can be divided into mixed sand storage and stratified sand two kinds. Sometimes the stratified sands will turn into mixed sand for storage. Therefore, the method of blending sand storage will be introduced. For mixed sand storage, fine sand should be selected, the water content should be controlled at 2%-4%, the indoor air humidity should be kept at 85%-90%, and the sand content should be about 2 times that of the seed. Mix the sand and seeds together and store them on the surface of the soil. Note that do not put them on the concrete floor or on poorly ventilated ground. If you put them in places with poor air permeability, you can easily make the seeds “spontaneous†or The phenomenon of “self-heating†has become an incentive to further promote respiration and eventually led to the death of the seeds from alcoholism. A 10 cm layer of fine sand shall be spread over the land surface, and then the well-mixed seeds shall be layered. After they are all piled up, they shall be covered with a layer of sand 4 cm to 6 cm. During the storage of seeds, regular inspections should be conducted to ensure proper indoor air temperature and maintain the safe moisture content of seeds. If the sand is a little dry, you can spray a small amount of water to maintain humidity. After the A. chinensis seeds are collected in the sand, it is beneficial to the germination of the seed buds, and the emergence of seedlings is neat and the stress resistance is strong.
