Abstract
The invention discloses a method for low-temperature accelerating germination for acer palmatum seeds, belonging to the field of gardening production. The method comprises: removing the wing of a fruit, then selecting seeds, and dipping the seeds in clean tap water for 24 hours; then, mixing the seed with vermiculite at the ratio of 1:4, and keeping moisture (relative moisture degree is 75%); refrigerating at the temperature of 2-5DEG C; after refrigerating for 20 days, observing whether the seed has a crack; and when more than 1/3 seeds have cracks, sowing. The method for low-temperature accelerating germination for acer palmatum seeds can shorten seedling culture period, lower seedling culture cost, improve rate of emergence and is suitable for sowing and breeding valuable breeds or breeds with low maturing rate. In the method, large-scale industrial seedling culture can be carried out so as to satisfy the requirements of markets.
Description
Technical field
The invention belongs to field of horticultural production, relate to Acer palmatum seed low-temperature germination method.
Background technology
Acer palmatum (Acer Palmatum) is called refined maple, is the Aceraceae Acer.Originate in the Chinese Yangtze river basin, also there is distribution in Japan, the Korea peninsula, and China mainly is distributed in each province, the Yangtze river basin, is born in the border or sparse woods on the following mountain region of height above sea level 1200m, hills more.Shank Acer defoliation small arbor, high about 8m, bark Dark grey, annual shoot purple or pale purple green; Light gray purple of perennial branch or darkviolet.Leaf is to life, and diameter 7-10 centimetre, base portion cuts shape, the palmate drastic crack, and 5～9 of slivers, common 7 split, sliver ovum shape Long Circle or lanceolar, sharp point in top or long sharp point, there is irregular heavy sawtooth at the edge, the close living pubescence of tender leaf.Blade is green in the red back of elder generation in spring, becomes redness to autumn.Give birth on the corymb top, blooms the flower aubergine behind the foliation.Samara just is an aubergine, and ripe back is pale brown look, the nutlet sphere, and 7 millimeters of diameters, vein is remarkable; Wing and nutlet are long altogether 2-2.5 centimetre, and be wide 1 centimetre, the flare up obtuse angle.May at florescence, really September phase.
Acer palmatum happiness is warm, humid climate and half cloudy environment intolerant to waterlogging, and is more drought-enduring, subjects to a day bright evil summer in the isolated planting of sunlight straight shot places; Fit and be born in fertile, moistening and soil that draining is good, cold resistance is not strong, and acidity, neutrality and calcareous soil all can adapt to, and are the good ornamental tree species of competitively cultivating in recent years.
Acer palmatum is because of its tree performance grace, and is flourishing, leaf beautiful, the leaf look various, very general in city trees and shrubs is used, and is famous ornamental plantation and courtyard greening seeds, also is precious family potted plant kind.But isolated planting, group planting, mass-planting are interspersed between lawn, mound, small stream limit, Chi Pan and corner, road, wall limit, booth corridor, mountain stone, and be all very proper, if set off as background with evergreen tree or white-washed wall, outstanding sense is beautiful colourful.Make potted landscape or potted plant to be used for indoor beautifying also extremely graceful.
The Acer palmatum propagation method mainly contains the method for seminal propagation, propagation by grafiting and cottage propagation.In existing seed seedling-raising technology, conventional way is the method that adopts first hotbed vernalization to transplant again, promptly the seed high density of earlier sand being hidden is broadcasted sowing on the seedbed of humidity more than 80%, on take little shed, the high 50cm of canopy, the lid plastic film carries out hotbed vernalization, treats that percentage of seedgermination reaches 80% and can transplant when above.This germination accelerating method management is more extensive, planting percent is lower, is not suitable for the breeding of the low kind of rare (famous and precious) kind or ripening rate, and it is uneven to sprout in addition, is not suitable for carrying out large-scale industrialized growing seedlings, and is difficult to satisfy the demand in market.
Summary of the invention
It is meticulousr to the purpose of this invention is to provide a kind of management, improves emergence rate, shortens growing-seedling period, reduces the technical method of the Acer palmatum seed growing vernalization of seedling cost.
Technical scheme of the present invention comprises following steps:
(1) remove wing: can remove wing by machinery, also can be with other go the wing mode;
(2) seed selection: select physically well developed, full, grain is big and do not have the kind grain of damage by disease and insect, standbyly carry out presprouting of seeds and handle;
(3) seed soaking: with clean running water seed soaking 24 hours.In the seed soaking process, note to observe, stir repeatedly, fully absorb water to well with seed;
(4) refrigeration: the seed after will soaking seed mixes with vermiculite, mixed proportion is 1: 4, and keep moistening (relatively wettability be 75%), valve bag with 25 * 17cm specification carries out packing, every bag of about 100 seeds, make a call to two holes and be beneficial to ventilation on valve bag, put it in the refrigerator, design temperature is 2～5 ℃;
(5) whether vernalization: beginning to observe seed after refrigerating 20 days has breach, observes once in per five days, and removing has the seed that goes mouldy, and can sow when more than 1/3rd breach being arranged when seed has;
(6) sowing: sowing media is a vermiculite: turfy soil=1: 2, and (in every hole gauge lattice 6 * 6 * 4cm, the cave dish specification 54 * 28cm), earthing is the twice of seed diameter at 32 Confucian Garden wood cave dish in sowing, behind the earthing first pass water is irrigated, note later on observing, keep ground moistening, but avoid waterlogging.The time thinning of spending for three weeks approximately can all sprout.
By technical scheme provided by the invention as can be seen, the method for Acer palmatum seed low-temperature germination of the present invention, its feature at first are that the seed after the seed soaking is mixed with vermiculite, and mixed proportion is 1: 4; Next is to refrigerate processing under 2～5 ℃, effectively breaks seed dormancy, improves percentage of seedgermination, reduces seeding quantity, improves emergence rate greatly.
The seed of handling by the low-temperature germination method, after planting, not only emergence rate is hidden seed than traditional sand and is improved approximately 40%, improves seed sprouting and ground threshing emergence rate greatly, and can shorten growing-seedling period, emerges half a year in advance, has reduced seeding quantity.The low-temperature germination method is simple and easy, and cost is low, is easy to grasp.This germination accelerating method relatively is fit to the low kind of famous and precious kind or ripening rate and carries out seed propagation, helps protecting elite plant strain and famous and precious Acer palmatum kind.
Embodiment
Collect ripe Acer palmatum fruit in early December, remove seed wing, select physically well developed, full, grain is big and do not have 300 in the seed of damage by disease and insect, be placed on and hang over shady and cool dry place storage in the seed packet.March 4 is with clean running water seed soaking 24 hours, fully absorbs water to well with seed; Then seed is mixed with vermiculite, mixed proportion is 1: 4, and keeps 75% humidity, reinstall in the valve bag of 25 * 17cm, making a call to two diameters on valve bag is the 0.5cm hole, and two holes are at a distance of 5cm, be positioned at the valve bag middle part, put into refrigerator, design temperature is 2～5 ℃.Whether have breach, observed 1 time every 5 days then if beginning to observe seed after 20 days, had small quantities of seed that breach is arranged in the time of the 30th day, found have the seed more than 1/3 that breach is arranged approximately April 10, sows immediately.The statistics emergence rate was about 90% in after planting 40 days.
