Abstract

The invention discloses breeding and method in strong sprout of a kind of Acer Truncatum Buge seedling, Acer Truncatum Buge main bud has stronger rudiment power, under natural upgrowth situation, its germination rate is up to 80% 100%, side each main bud, general raw two accessory buds and multiple kryptoblast, when main bud is impaired or by other cultivation step, as pruned, stump, after the stimulation of felling etc., accessory bud and kryptoblast can quickly be sprouted, grow rapidly young sprout, this characteristic is highly beneficial for the operation of tree-like cultivation and picking leaves woods, aborning can be as required, 13 eugonic coppice shoots are stayed to continue to cultivate, unnecessary rudiment need to manually be erased additionally, the kryptoblast of Acer Truncatum Buge lasts a long time, up to 20 30 years as long as, this characteristic updates highly beneficial for tree body.

Description

Breeding and method in strong sprout of a kind of Acer Truncatum Buge seedling

Technical field

The present invention relates to breeding and method in strong sprout of a kind of Acer Truncatum Buge seedling.

Background technology

Acer Truncatum Buge is a kind of to collect that oils and fats, protein, tannin, flavone etc. are edible and medical material is new resources tree all over the body Kind.This plant seed seed is relatively big, and kernel oil content one, oil yield, higher than Semen Allii Tuberosi oil yield, and this oils and fats belongs to rich in oil Acid and linoleic acid are main semi-drying oil, and quality is the most excellent, are that this rare seeds kernel is containing egg in edible vegetable oil White matter one, possesses the kind aminoacid of needed by human, is that a kind of nutritious vegetable protein Acer Truncatum Buge seed coat tannin content is up to, And annual renewable acquisition, it is that to produce the medical value of the suitable for plant kind Acer Truncatum Buge oils and fats of tannin and tannin the highest, this oil Fat can promote new tissue growth, has inhibitory action tannin to have in significantly analgesia and blood coagulation resisting function blade to tumor cell Containing flavone, chlorogenic acid, etc. bioactive substance and nutrient substance multiple, there is preferable DEVELOPMENT PROSPECT.

Secondly, Acer Truncatum Buge or a kind of excellent afforestation and view seeds, in China's improvement of the ecological environment Play great function.These seeds have mycorhiza, can promote seedling growth, and Acer Truncatum Buge drought resisting is barren-resistant, have stronger comprehensive Anti-adversity ability, in the year of 1 year Shaanxi arid, in cooperation of China and Germany West part of Shaanxi afforestation project, Acer Truncatum Buge is afforested in Qinling Mountain Areas Survival rate is the highest, exceedes the seeds such as Robinia pseudoacacia L., Pinus tabuliformis, Cacumen Platycladi, Prunus armeniaca L.var.ansu Maxim., especially in the great drought time that year is not seen once in a hundred years, Acer Truncatum Buge table Revealing the strongest drought-resistant ability, survival rate comes out at the top.Afforesting under the stone matter thin soil land occupation condition of Shanxi, Acer Truncatum Buge survival rate is high In Pinus tabuliformis.This seeds tree crown dense shade, tree performance is graceful, and blade profile is beautiful, and nascent tender leaf color is red, grows vigorous time-varying green, enters the most again Becoming orange-yellow or red, ornamental value is the highest, is northern important autumn scenery red-leaf tree species." the west that Beijing, China capital is famous Mountain red autumnal leaves ", Acer Truncatum Buge is exactly one of chief species therein.Domestic previously using it as green planted city, road and sight spot, showplace Fine tree species.At present, these seeds are just being widely used in China's semi-moist, the afforestation of semiarid zone and afforestation project, Become the important vanguard tree seed of Silvicultural Engineering and revegetation.

Although the research to these seeds has been achieved for many achievements in research, but comes out in producing and be badly in need of solving Problem certainly is still a lot, such as improved variety resources base Construction Problems, applied basic research weakness etc..

Summary of the invention

It is an object of the invention to provide breeding and method in strong sprout of Acer Truncatum Buge seedling, to solve in above-mentioned background technology The problem proposed.

For achieving the above object, the present invention provides following technical scheme: breeding and strong sprout side of a kind of Acer Truncatum Buge seedling Method, step is as follows,

(1), seeding and seedling raising

1), nursery lot selects the quality of nursery lot land occupation condition, directly affects the quality of nursery stock.This test and Selection fills

Condition of irrigating is good, and physical features is smooth, and the soil texture loosens, and well-drained location, quality is sandy loam, experimental field irrigation conditions Convenient, quality is loam, middle fertility；

2), make bed for vegetable soil wholely, ploughed deeply ground, garden before the winter and the every h of basal dressing uses wet barnyard manure 45t, diamidogen, crosses phosphorus The acid each 750kg of calcium, shallow plowing whole ground bedding, furrow width 1.2-1.5m before sowing in spring；

3), broadcasting front seed treatment and set accelerating germination and dry seeds altogether and directly sow two kinds of contrast tests, wherein, accelerating germination includes that again clear water soaks Behind kind 1 day, 2 days or 3 days, and seed soaking, the kind such as bamboo basket accelerating germination processes, and bamboo basket germination accelerating method is one week prior to seeding, by full kind Sub-warm water (35-41 DEG C) soaks one day, puts in bamboo basket, covers straw screen or mat, be placed under 20-30 DEG C of room temperature after pulling out, and every day waters Water also stirs 2-3 time, to " splitting mouth to show money or valuables one carries unintentionally " seed reach 20% time, can sow；

4), type of seeding: using program request or drilling, seeding row spacing is 5*30-40cm, seed level 2-3cm, sowing quantity program request 120- 150kg/h, drilling 180-225 kg/h, 2, every cave seed, before sowing, will experimental field fill sufficient water, broadcast when soil moisture content is suitable Kind, after planting covering wheat straw or mulch film；

(2), nursery stock manages, and after planting, when half seedling has two panels lobule to launch, carries out thinning and fills the gaps with seedlings, at seedling growth In season, remove weeds and watering, fertilizing in time, and loosen the soil in time after watering, keep soil from packing together, for stump plant, the most in time Erase the lateral bud of germinating in stump stake and side shoot, ensure a major branch bar robust growth.
