Germination accelerating method for carpinus cordata seeds

Abstract

The invention discloses a germination accelerating method for carpinus cordata seeds. The germination accelerating method comprises the following steps that a coarse grain gravel layer, a grass carbon or perlite layer, a wool fabric gauze element with single-layer meshes smaller than 2mm, a seed layer soaked by potassium permanganate, a wool fabric gauze element with single-layer meshes smaller than 2mm, a fine sand layer and a sawdust layer are sequentially laid from bottom to top in a shady, cool, ventilated and well-drained zone, and then the zone is watered thoroughly, after the zone is dried, the zone is watered once, it is guaranteed that the seeds are moist, the temperature is controlled between 5 DEG C and 25 DEG C, after the outdoor temperature is lower than 5 DEG C, the seeds are moved into a room, the seeds are located between the upper sand and the lower sand, the treatment time is 4 months-5 months, and when 20% of the seeds crack, the seeds are moved into a freezer with the temperature of minus 15 DEG C and sown in early spring of the next year. According to the method, a high-quality seed low-temperature moisturizing method is adopted to continue seed vitality and prevent the seeds from entering a dormant state, the seeds are treated while being picked in the current year, the budding rate can reach 80% or above, and the treated seeds can emerge in same year after being sown in the spring of the next year.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for accelerating germination of hornbeam seeds. Background technique [0002] Qianjin hornbeam (Carpinus cordata B1.), also known as Qianjin elm, Hua hornbeam (small fruit Qianjin elm), Banlazi, see air dry, big leaf hornbeam, etc., is a plant of the genus Hornbeam in the Betaceae family. At present, the genus Carpinus L. belongs to 50 species. There are 33 species and 8 varieties in China, which are distributed in Northeast, North China, Southwest, Shaanxi, Gansu, Henan and other places. It is the distribution center of Carpinus L. plants. [0003] In order to better protect the resources of the hornbeam in Changbai Mountains, the sexual breeding method is adopted for seed propagation to provide high-quality seedlings for the afforestation of the hornbeam, to expand its population and germplasm resources, and to ensure the long-term use of the hornbeam by ...
