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
The invention belongs to field of planting, be specifically related to a kind of seedling-cultivating method improving strawberry percentage of seedgermination.
Background technology
Strawberry cry again the red certain kind of berries, the foreign certain kind of berries, the certain kind of berries etc., be a kind of fruit of redness.Strawberry is the common name to rose family strawberry plants, belongs to herbaceos perennial.The outward appearance of strawberry is in heart-shaped, and delicious red tender, pulp succulence, containing special strong fruit aroma.Strawberry nutrition is worth high, containing enriching vitamin C, and effect of helpful digestion; Meanwhile, strawberry can also consolidate gums, fresh breath, moist throat.
The natural germination rate of strawberry seed is generally at 30-40%, and not only emergence rate is low, and it is irregular to emerge, and within after planting 10 days that have, just germinates, and then needing of having even reaches 90 days ability for 40 days and germinate.This adds difficulty to comprising the seedling management of transplanting seedlings, not only take a lot of work but also consuming time, and the wherein seed that do not germinate of 60-70%, largely cause excellent genetic loss, decrease the successful probability of breeding of new variety, seriously perplex the progress of strawberry scale crossbreeding work.Although adopt vegetative propagation in the market, nursery stock price is more expensive, and high quality seedling is comparatively in short supply more, and seedling transport inconvenience, can not meet the needs of different user in addition.
Summary of the invention
In order to solve the problem, the invention provides a kind of seedling-cultivating method improving strawberry percentage of seedgermination, overcome the defect of existing strawberry seed seedling-raising technology, increased substantially germination rate and the Phase ofsprouting of seed, and institute's nursery wood has good resistance.
The present invention is achieved through the following technical solutions:
Improve a seedling-cultivating method for strawberry percentage of seedgermination, comprise the steps:
(1) seed disinfection: seed is placed in the liquor potassic permanganate that mass fraction is 0.5 ~ 0.8%, keeps solution temperature to be 35 ~ 45 DEG C, takes out after slowly stirring 25 ~ 35min;
(2) seed soaking: after the seed after sterilization being placed in the resistant to ammonia azotobacter liquid immersion 2 ~ 3h of 2 ~ 4%, take out to be put in the warm water of 40 ~ 50 DEG C and soak 3 ~ 5h, and then 2 ~ 3h being dried in taking-up, be finally again put in the warm water of 45 ~ 55 DEG C and soak 2 ~ 3h;
(3) ultrasonic process: the seed ultrasonic processing instrument after seed soaking is carried out ultrasonic process, it is 8 ~ 12min that handling duration controls;
(4) moisturizing vernalization: the seed handled well is put in wet gauze, and be placed in insulating box vernalization process;
(5) planting seed: when seed over half shows money or valuables one carries unintentionally, be seeded on seedbed, and cover the thick fine sand of one deck 0.5cm;
(6) seedling is planted surely: when growing 4 ~ 6 true leaves after seed sprouting and portable surely plant.
Further, step (2) described warm water be through magnetic field process after magnetized drinking water.
Further, step (3) described ultrasonic frequency is 35 ~ 45KHz.
Further, step (4) described Thermostat Temperature Control is 25 ~ 30 DEG C.
Further, the described fine sand particle diameter of step (5) is 0.25 ~ 0.35mm.
The present invention has following beneficial effect: this method first carries out routine disinfection to seed, be placed on seed soaking in resistant to ammonia azotobacter liquid again, improve potentiality of seed and Seedling Quality, the immersion treatment of magnetized drinking water to carry out disinfection sterilization to the surface of the seed further, reduce later stage disease and send out rate, the weak magnetic simultaneously had improves Interior Seed physiological status, improves the differentiation of later stage bud; To seed soak-dry-operation of soaking again makes the permeability of seed outside strengthen, being conducive to seed, to break chest neat, and percentage establishment of seedling improves; After ultrasonic process is carried out to seed, further promote the sprouting of seed and the growth of root system; The comprehensive function of above-mentioned processing method make percentage of seedgermination stable remain on more than 90%, and it is neat to emerge, and seedling-growing time also shortens more than 30% than common breeding method in addition, can improve the seed selection success rate of new varieties.
