Abstract
The invention discloses a method for quickly culturing seedlings of ginkgo trees, and relates to the technical field of culturing, planting and managing seedlings of ginkgo trees. The method comprises the following steps of processing seeds before sowing, sowing in a proper period, performing a sowing technique and managing after sowing. The method is characterized in that when the seeds are processed before sowing, the germination of the seeds is accelerated through a heated brick bed, a seedling raising room can be used for accelerating the germination of the seeds, firstly, the seeds are screened out, the screened seeds are put on a shed frame in a layered manner, a fire is made for heating, the indoor temperature is kept to be 25-30 DEG C, the relative humidity is 80%, the heating lasts for 4 days, and when the lengths of radicles exposed out of seed kernels are the lengths of the seed kernels, the seeds can be sowed into soil in batch. The operation of the method is simpler, the growth period can be prolonged, nursery stocks are high, the diameter growth quantity is larger, and the increasing of the economic benefits of culturing the seedlings of ginkgoes is facilitated.
Description
Technical field
The present invention relates to ginkgo seedling grow administrative skill field, relate to the 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 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 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 fiery pit vernalization, seedling room can be utilized to carry out, first seed is sifted out, layering is put on frame, makes a fire and heats, indoor maintenance temperature 25-30 DEG C, relative moisture 80%, heat 4 days, expose until radicle and sow down to during kind of core length in batches.
During described fiery pit vernalization, gingko seeds germinates irregular and has 10-25% without embryo, and in time chitting piece should be sorted out sowing, remaining continues vernalization, broadcasts for the first time, often within 5-7 days, broadcast once later during germination rate 10%, divides a 4-5 to criticize and finishes.
Described broadcast rear management reply nursery stock and carry out carbon ammonium and topdress, at the beginning of 5 months, early June, early July respectively execute once, fertilizing amount is 20 kilograms every mu, trench digging applies, cover immediately after executing, water, meanwhile, every 10 days foliage-sprays 0.3% urea liquid and potassium dihydrogen phosphate, connect spray 3-6 time.
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 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;
When broadcasting front seed treatment, carrying out vernalization to seed is adopt fiery pit vernalization, and seedling room can be utilized to carry out, first sifted out by seed, layering is put on frame, makes a fire and heats, indoor maintenance temperature 25-30 DEG C, relative moisture 80%, heat 4 days, exposes sow down to during kind of core length in batches until radicle.
During the vernalization of fiery pit, gingko seeds germinates irregular and has 10-25% without embryo, and in time chitting piece should be sorted out sowing, remaining continues vernalization, broadcasts first time, often within 5-7 days, broadcast once later during germination rate 10%, and a point 4-5 criticizes and finishes.
