Problems solved by technology

Because Quercus japonica seeds are hard seeds, there are many factors in the natural germination process that lead to a low success rate of seed germination, and the natural germination of seeds is far from being able to offset the reduction in resources
However, in traditional production, the germination rate of Quercus quercus seeds without any hormone treatment is often only about 50%, and the germination time is late and the emergence is irregular, which limits the large-scale planting of Quercus quercus

Embodiment 1

[0026] Collect mature Quercus japonica seeds in autumn and place them in airtight containers for 2 days. Wash the sealed oak seeds with clean water, and then spread them in a ventilated room without direct sunlight. Manually remove impurities such as shells, twigs, leaves, etc., and remove wormholes, abnormal shapes, damages and small shapes. Seed. Soak the washed Quercus quercus seeds in 0.3% potassium permanganate solution for 40 minutes, then remove them, rinse them with clean water and dry them in the shade. Soak the sterilized Quercus japonica seeds in water for 2 days to fully absorb water and swell; then fully stir the Quercus japonica seeds in clean water, then let them stand to remove unfulfilled seeds or empty shells floating on the water surface, and finally repeatedly scrub the remaining The seeds of Quercus japonica are washed and then fished out and drained. The soaked Quercus japonica seeds were soaked in 100 mg / L auxin solution for 3 days.

Abstract

The invention discloses a method for promoting germination of quercus acutissima seeds. The method is characterized by comprising the following working procedures: seed collection, seed pretreatment, sand storage germination acceleration and breeding management. The collected ripen quercus acutissima seeds are subjected to selection, disinfection, immersion and auxin treatment, and then sand storage germination acceleration is performed; germinated seeds can be obtained by breeding management. According to the method for promoting germination of the quercus acutissima seeds, seed dormancy can be effectively broken through only by immersion in plant hormone with a proper concentration and sand storage treatment; therefore, germination of the seeds can be accelerated, and the germination rate can be improved; the technical operation is simple, the cost is low, the operation is convenient, and the method is suitable for being popularized, and has higher economical, social and ecological benefits.

Description

technical field [0001] The invention relates to a method for accelerating germination of seeds, in particular to a method for promoting the germination of Quercus japonica seeds. Background technique [0002] Quercus acutissima Carruth (Quercus acutissima Carruth), also known as Qinggang and oak bowl tree, is a tree of the genus Quercus in the family Fagaceae. It is 30 meters high and 1 meter in diameter at breast height. The bark is dark grayish brown and deeply split. Born in the sunny slopes of mountains at an altitude of 60-2200 meters, it forms small pure forests or mixed forests. It is positive and likes light and humid climate. Cold-resistant, drought-resistant and barren, not resistant to water and humidity, not resistant to salt and alkali, it grows best on moist, fertile, deep, well-drained neutral to slightly acidic sandy loam, poor drainage or waterlogged land is not suitable for planting. Mixing with other tree species can form a good stem shape, deep roots, an...
