Method for promoting secondary germination of maple trees in summer

Abstract

The invention discloses a method for promoting secondary germination of maple trees in summer. The method comprises the following steps of taking out stored maple tree seeds, adding the maple tree seeds into a potassium permanganate solution with the concentration of 0.3%-0.8% at the temperature of 35-40 DEG C, soaking for 3-5 hours, and fishing out the maple tree seeds; selecting sandy loam whichis slightly acidic, wet, good in water permeability and good in irrigation condition, conducting furrowing after fertilizer spreading, spreading a Chinese herbal medicine disease and insect pest resistant agent into the sandy loam, spreading the treated maple seeds, spreading a layer of fine soil on the maple seeds, wetting surface soil by spraying, and keeping water in the surface soil; and after the seeds sprout out of the soil and grow into seedlings, applying fertilizer to the maple seedlings, promoting rapid growth and lignification of the seedlings, and obtaining the maple seedlings. Bymeans of the method, the germination rate of the maple seeds is greatly increased, and the planting survival rate is increased; and meanwhile, after the seedlings are cultivated from the treated seeds, the resistance to diseases is remarkably improved after the seedlings grow up, and the method is suitable for large-scale planting.

Description

technical field [0001] The invention relates to the field of maple tree planting, in particular to a method for promoting secondary germination of maple trees in summer. Background technique [0002] Maple is a tall tree. As the tree ages, the crown gradually opens and is round; the branches are brownish red to brown, with small holes, and the branches are black brown or gray in winter; the fruit is 5.5-7.5 cm long and 2-3.5 cm wide. Cylindrical bell-shaped, round base, 5-7 mm long seeds, shiny, olive green to yellow; flowering in May, fruiting in August. Maple leaves are gorgeous in color and unique in shape, and can be used to make bookmarks, specimens, etc. The maple tree has horizontal branches and beautiful tree posture, and most of them are weakly positive tree species. It is an important middle-level tree that expresses autumn colors in the scenic forest. [0003] It is a common way to plant maple trees when using mature maple seeds for secondary seedling cultivatio...
