Seedling culturing method capable of raising emergence rate of strawberry seeds

Abstract

The invention discloses a seedling culturing method capable of raising the emergence rate of strawberry seeds. The method comprises the following steps: 1, seed disinfection; 2, seed-soaking treatment; 3, ultrasonic treatment; 4, moisture retention and germination accelerating; 5, seed sowing; 6, field planting of seedlings. According to the method, the seeds are subjected to conventional disinfection in the first place and then placed in an ammonia-resistant azotobacter solution for being subjected to seed-soaking treatment, the germination potential of the seeds and quality of the seedlings are improved, through the soaking treatment through magnetic water, further sterilization and disinfection are conducted on the surfaces of the seeds, the disease attack rate at a later stage is lowered, meanwhile, the physiological status inside the seeds is changed by weak magnetism which the seeds have, and differentiation of buds at the later stage is improved; through the operation conducted on the seeds, namely soaking, airing and further soaking, the external permeability of the seeds is reinforced, neat testa-breakage of the seeds is facilitated, and the percentage of seedling establishment is raised; after the ultrasonic treatment is conducted on the seeds, seed germination and root growth are further promoted. Through the combined action of the treatment method, the germination rate of the seeds is stably maintained over 90%, the seedlings emerge neatly, in addition, the seedling emergence time is shortened by above 30% compared with a common breeding method, and the breeding success rate of a new variety can be raised.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a seedling raising method for improving the germination rate of strawberry seeds. Background technique [0002] Strawberry is also called cranberry, raspberry, ground berry, etc. It is a kind of red fruit. Strawberry is a general term for plants of the genus Fragaria in the Rosaceae family, which belongs to perennial herbaceous plants. Strawberries are heart-shaped in appearance, delicious, red and tender, with juicy pulp and a special rich fruit aroma. Strawberries have high nutritional value and are rich in vitamin C, which can help digestion; at the same time, strawberries can also strengthen the gums, freshen the breath, and moisturize the throat. [0003] The natural germination rate of strawberry seeds is generally 30-40%. Not only the emergence rate is low, but also the emergence is irregular. Some germinate 10 days after sowing, while others need 40 days or even as l...

Problems solved by technology

[0003] The natural germination rate of strawberry seeds is generally 30-40%. Not only the emergence rate is low, but also the emergence is irregular. Some germinate 10 days after sowing, while others need 40 days or even as long as 90 days to germinate

This increases the difficulty of seedling management including seedling transplantation, which is labor-intensive and time-consuming, and 60-70% of the ungerminated seeds cause the loss of good genetic genes to a large extent, reducing the success of new breed selection The probability of this problem has seriously troubled the progress of strawberry cross-breeding work on a large scale

Although asexual reproduction is mostly used in the market at present, the price of seedlings is relatively expensive, and high-quality seedlings are in short supply. In addition, the transportation of seedlings is inconvenient and cannot meet the needs of different users.
