Abstract
The invention provides a rapid seedling growing method of gingko trees and relates to the technical field of seedling growing and planting management of the gingko trees. The rapid seedling growing method comprises the following steps: treating seeds before sowing; sowing in a suitable period; carrying out a sowing technology; and managing after sowing. The rapid seedling growing method is characterized in that in the step of treating the seeds before sowing, the germination acceleration on the seeds adopts a stratification mode; cold frames with the depth of 20cm-30cm are dug at a sun-exposed part and fine sand with the thickness of 10cm is spread at the bottom; a seed-sand mixture is spread in the cold frames for the thickness of 10cm and is covered with one layer of fine sand; an arch shed is established by a plastic film and is sealed, and the temperature in the shed is kept at 18-30 DEG C; a 700-time diluted solution of 70% thiophanate methyl is spread once every 5-7 days and the soil in the arch shed is turned once; and sprouts grow out after 12-20 days. The rapid seedling growing method is simple to operate; the growth period can be prolonged, seedlings are high and the radial growth amount is large; and the economic benefits of seedling growing of the gingko trees can be improved favorably.
Description
Technical field
The present invention relates to ginkgo seedling grow administrative skill field, relate to the sowing vernalization fast seedling-cultivating method with a kind of ginkgo.
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
Technical problem to be solved by this invention is to provide one to extend vegetative period, the sowing vernalization fast seedling-cultivating method of the ginkgo that nursery stock is high, Diameter growth amount is larger
Technical problem to be solved by this invention realizes by the following technical solutions:
A sowing vernalization fast seedling-cultivating method for ginkgo, comprises the following steps,
Broadcast front seed treatment: February, early and middle ten days carried out selected and vernalization to seed;
Proper seeding: sowing can be completed before the Spring Equinox, thickness of sowing according to cultivation object and determining, cultivate then nursery stock wood time, per mu yield sowing 30,000 strains; When cultivating the 2-3 life seedling being used for grafting, with per mu yield sowing 1.5-2 ten thousand strain;
Seeding technique: wholely, do bed, trench digging, soil disinfection, before sowing, ginkgo radicle 0.3 centimeters below collar is cut off, program request immediately, seed base-root is downward, plant rib parallel to the ground, thickness of earth-fill cover for degree, and sprinkles wheat bran with drowning seed on sowing row, with good conditionsi can laying plastic or take shed;
Broadcast rear management: before and after coming up, keep seedbed moistening, shed and covering remove after hardening by the first tenday period of a month in May;
It is characterized in that: described when broadcasting front seed treatment, carrying out vernalization to seed is adopt stratification, dig the cold bed of dark 20-30 centimetre at area without shade, bottom spreads 10 centimetres of fine sands, is spread out in cold bed by kind of a husky mixture, thickness 10 centimetres, on cover one deck fine sand, take the sealing of bow canopy with plastic film, keep temperature of shed 18-30 DEG C, within every 5-7 days, stir once with 70% thiophanate methyl, 700 times of liquid sprinkles, within 12-20 days, can germinate.
Temperature during described stratification is no more than 30 DEG C.
Described front seed treatment of broadcasting is soaked seed 4 hours by 0.5%-1.0% copper sulphate medicine company before vernalization, takes out rinsing and dry after seed soaking.Play the effect of sterilizing.
The invention has the beneficial effects as follows: the present invention's operation is comparatively simple, can vegetative period be extended, nursery stock is high, Diameter growth amount is comparatively large, be conducive to the economic benefit improving ginkgo nursery.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
A sowing vernalization fast seedling-cultivating method for ginkgo, comprises the following steps,
Broadcast front seed treatment: February, early and middle ten days carried out selected and vernalization to seed;
