Abstract

Relating to the technical field of seedling breeding, the invention provides a weak current germination accelerating method for ginkgo tree species. The method includes: placing carefully selected seeds into an insulating germination accelerating box to conduct germination accelerating, disposing electrode plates symmetrically on both sides in the germination accelerating box, spraying a germination accelerating liquid evenly every 2.5h, at the end of each spraying, connecting the two electrode plates disposed in the germination accelerating box to the positive pole and negative pole of a power supply respectively, switching on the power and introducing micro-current with intensity of 15microA to the seeds for 25s every 15min, conducting energization 4-6 times after each germination accelerating liquid spraying, and 24h later, taking the seeds out of the germination accelerating box, placing the seeds in a germination accelerating chamber to further perform germination accelerating for 4d, and when the exposed radicles reach a seed nucleus length, applying the seeds to sowing. The germination accelerating method provided by the invention can enhance the seed germination rate and reduce necrosis after germination, intermittent switch-on of weak current can improve the germination accelerating effect of the germination accelerating liquid on seeds, thus being conducive to increasing the economic benefits of ginkgo seedling culture.

Description

The weak current germination accelerating method of a kind of ginkgo seeds

Technical field

The present invention relates to seedling-wood breeding technical field, particularly relate to the weak current germination accelerating method of a kind of ginkgo seeds.

Background technology

Ginkgo is the distinctive rare tree of China, and collection kind of use, Ye Yong, material are used for one.Ginkgo kernel is nutritious, dietotherapeutic, is exactly the first-class dry fruit that health is prolonged life from ancient times, in China's dry fruit is produced, occupy the 4th.Ginkgo timber is excellent, have the laudatory title of " silver-colored incense wood ", and be the desirable timber of craft articles, mould, musical instrument and furniture, price is higher.The ginkgo timber forest of afforesting latter 25 years, every mu of volume of timber can reach 10 cubic metres.Ginkgo is intolerant tree species, and drought-resistant ability is strong, but intolerant to waterlogging, non-resistive.Therefore select should select hillside fields during milpa, avoid depression and air port place.The method of conventional stealthy nursery is all the method for common seeding and seedling raising, gingko seeds is after storage, the after-ripening stage is completed before sowing, can sow, without vernalization etc. out, this type of seeding is fairly simple, be easy to grasp, but it is slower and irregular to emerge, the seedling growth phase is short, and seed output and quality is also slightly poor.

Summary of the invention

The object of the present invention is to provide the weak current germination accelerating method of a kind of ginkgo seeds, to solve the problems of the technologies described above.

Technical problem to be solved by this invention realizes by the following technical solutions:

The weak current germination accelerating method of a kind of ginkgo seeds, it is characterized in that, comprise the steps: to carry out selected to seed, seed after selected puts into the vernalization of insulation vernalization casing, vernalization casing upper end is uncovered, the bottom of vernalization casing offers sieve aperture, bilateral symmetry in vernalization casing is provided with battery lead plate, after seed loads after vernalization casing, every 2.5 hours, even sprinkling vernalization liquid, be sprayed to till vernalization liquid flows out from the bottom of vernalization casing, after the complete vernalization liquid of each sprinkling, two electrode plate arranged in vernalization casing are connected respectively positive pole and the negative pole of power supply, switch on power and pass into micro-electric current to seed, current intensity is 15 μ A, each energising 25s, every 15min energising once, the complete vernalization liquid of each sprinkling is energized 4-6 time later, after 24 hours, seed is taken out from vernalization casing, be placed in germinating cabinet and continue vernalization, temperature 25-30 DEG C is kept in germinating cabinet, relative moisture 80%, continue vernalization after 4 days, when radicle exposes to kind of core length, namely can be used for sowing.

Sowing completes before the Spring Equinox, every mu of ground sowing 2.5 ten thousand strains; Concrete type of seeding is: wholely, do bed, trench digging, soil disinfection, and before sowing, ginkgo radicle 0.3 centimeters below collar is cut off, program request immediately, seed base-root is downward, kind of rib is parallel to the ground, and thickness of earth-fill cover for degree, and sprinkles wheat bran with drowning seed on sowing row; Before and after coming up, keep seedbed moistening, after hardening, adopt conventional method to manage.

Described vernalization liquid is formulated by the raw material of following weight portion: pure water 1000 parts, alcohol 0.3 part, cape jasmine 3 parts, folium isatidis 2 parts, felwort 4 parts, Herba Andrographitis 4 parts, azedarach 5 parts, 2 parts, garlic, ox dimple 6 parts, aloe 3 parts, lilac daphne 4 Fen, le bamboo 5 Fen, pivot store 2 parts, evodia rutaecarpa 6 parts, dragon must bend grass 6 parts, tree of heaven ailanthus bark 7 parts, common diuranthera root 4 parts, imperial beard 5 parts, polygonum flaccidum 3.5 parts, radish tassel 6.5 parts, Lysimachia foenum-graecum 3 parts, the banksia rose 4 parts by tabernaemontanus bulrush 4 parts, thousand;
