Blueberry seed propagation and seedling growing method

Abstract

The invention discloses a blueberry seed propagation and seedling growing method which comprises the following steps: a, putting harvested fresh mature blueberry into a bucket, thoroughly rinsing with water, and removing immature seeds and pulp floating on water; b, soaking and sterilizing the seeds with a potassium permanganate solution after the seeds are cleaned, sealing, washing with deionized water, sterilizing with carbendazim, and cleaning with clean water; c, mixing the seeds with river sand in a volume ratio, putting into a plastic bag, putting into a refrigeration chamber of a refrigerator, keeping temperature, taking out the seeds 40 days later, checking at regular time, keeping the humidity of a seed and sand mixture, after the seeds become white and sprout, sowing the seeds; d, performing strip seeding on the seeds and the sand when the seeds are sown, covering furrows with a layer of moss till seeds are not visible, watering, covering with a mulching film, and promoting the blueberry seeds to sprout out. The blueberry seed propagation and seedling growing method is simple and feasible and convenient to operate, a seed treatment method is handled, germination acceleration treatment is implemented on the seeds, buds can be promoted with the combination of a temperature accelerated stratification germination acceleration method and a medicine seed soaking method, and the seedling yield can be up to 90%.

Description

technical field [0001] The invention belongs to the technical field of plant seedling propagation, and more specifically relates to a method for blueberry seed propagation and seedling cultivation. It is especially suitable for breeding seedlings with post-ripening seeds and long dormant period seeds. Background technique [0002] Blueberry (Vaccinium Spp) is a blue berry, perennial shrub small berry fruit tree. It belongs to Rhododendronaceae, Vaccinium plant. Originated in North America, it is basically distributed all over the world. It is mainly distributed in areas with warm and cool climate and sufficient sunshine, such as North Korea, Japan, Mongolia, Russia, Europe, North America, and Heilongjiang, Inner Mongolia, and Changbai Mountains in Jilin, China. Blueberry fruit is rich in Nutrients have the functions of preventing brain nerve aging, protecting eyesight, strengthening the heart, anti-cancer, softening blood vessels, enhancing human body immunity, etc., with ...

Problems solved by technology

[0003] But blueberry seeds are not easy to reproduce, because blueberry seeds are extremely small and difficult to harvest, and because blueberry seeds will go dormant once they leave the fruit, it will be very difficult to break the dormancy and germinate. If the seeds are not treated before sowing, the germination after sowing The rate is extremely low, and the natural seedling rate is about 5%.

At present, there are few reports on blueberry seed propagation and seedlings in the literature, mainly using low-temperature stratification to accelerate germination and soaking seeds with gibberellin.
