Embodiment
Embodiment 1, and the method for planting southerm yew of present embodiment is the following step:
One, grows seedlings: seeding and seedling raising
(1), seed collection: in 10 months, the last ten-days period, collect seed when the southern enqlish yew fruit is peony, the seed clear water of adopting back soaked 4 days, changed water every day 1 time, rubbed with the hands and went arillus, cleaned, and spread out and dried in the shade I days.Thousand grain weigth 80 grams, good degree 95%.
(2), presprouting of seeds:
1., select leeward, shady and cool, the level land of ponding not, dig pit, cheat dark 35 centimetres, 25 centimetres of footpath, hole ￠, place mat river sand 4 cm thicks in the hole;
2., soak disinfection half an hour of above-mentioned seed with 0.05% liquor potassic permanganate;
3., get above-mentioned sterile-processed seed in regular turn in 1: 3 ratio and evenly mix with river sand, the seed with mulling is tiled in the heatable adobe sleeping platform then, 25 centimetres of thickness, cover one deck damp sand again, 4 centimetres of thickness make its surface equal with ground, and the lid layer straw protects shade and preserves moisture again.In 1 lunar crater, stir 1 time, as find the seed that goes rotten, in time reject.To late October in next year, the broken chest of seed is now white.
(3), ground, garden is built:
1., garden ground is selected:, short texture deep with soil layer, be rich in good, improper with a western exposure, the Xia Qiu of organic matter, draining and meet the paddy soils of harvesting then that arid can in time irrigate and be advisable;
2., preparing soil in rice field: behind harvesting semilate rice or late rice, treat to plough deeply once behind the antecedent soil moisture usually, hack once.Thereafter divide the railway carriage or compartment to make bed, 1.5 meters of wide beds (clean bed surface is wide 1.2 meters, and pavement is wide 0.3 meter), it is fixed that 20 centimetres of the height of bed, seedbed length are looked ground, nursery.
3., throw basal dressing: when making bed behind the hack, every mu applies 3500 kilograms of the pig cow dungs become thoroughly decomposed wholely, and 90 kilograms of instant high-quality composite fertilizers turn underground layer with fertilizer, flatten the railway carriage or compartment face, add yellow soil then on the face of railway carriage or compartment, native thick 4 centimetres.
(4), begin sowing in good time: the storage of seed by 1 year, have the part breach now white, seed is sifted out clean, sterilized 10 minutes with 0.05% liquor potassic permanganate seed soaking, clean with flushing with clean water again, can sow behind the airing open fire.Type of seeding is broadcasted sowing and two kinds of drillings, can choose wantonly wherein a kind of.
1., the method for broadcasting sowing is: seed is sprinkling upon on the seedbed of filling in yellow soil equably, covers seed with yellow soil, to lose seed degree of being, with liver moss the seedbed is all covered again;
2., the bar broadcasting method is: choose 10 centimetres of wide planks, press seed furrow, dark 2 centimetres filling on the seedbed of yellow soil, 15 centimetres of distances between the seed furrow evenly are seeded in seed in the ditch, and with gold zone earth mulch kind, 1 centimetre of thickness is used liver moss cover-seeding ditch again.
What more than should be specifically noted that is: the one, and strict control seeding quantity, every mu is 12～18 kilograms with kind, can have a strong impact on qualified seedling emergence rate too much with planting; The 2nd, after planting, to broadcast sowing and must the seedbed all be covered with liver moss, as long as drilling is with liver moss cover-seeding ditch.After coming up, liver moss is not thrown off yet, remain on the seedbed for a long time.The advantage of liver moss seedling-protection is, the protection seedbed is not splashed and the sunlight direct projection by rainwater, makes nursery stock not be subjected to sun burns and avoids forming mud rod death by suffocation because of stem, leaf are stained with mud.Should often keep loosing soil, moistening simultaneously, reduce the intertill and clean tillage recruitment. to approach but cover liver moss thickness, can not be too thick, as drouth rain not, available thin loess is pushed down liver moss, or moistening with sprayer water spray maintenance seedbed.
(5), field management:
1., seedling protects shade: before coming up, must the cool canopy frame is good, canopy is high 1.7 meters, will with branches and leaves shade around the seedbed dog days.
2., prevention waterlogging drought resisting: the southern enqlish yew seedling is afraid of arid and moist, and especially in the growth of seedling phase, on the occasion of the how fine few weather of rain, reply drain ditch, field, nursery is in time cleared up, and keeps no ponding in the ditch.Heat and drought condition season two season of autumn in summer, soak filling to nursery lot, be about 2 hours but soak the filling time, water can not be higher than the seedbed, soaks to irritate to be separated by 10 days at every turn.
3., the extermination of disease and insect pest: after coming up, on the occasion of rainy season, seedling is many because of rainwater, and air humidity is big, and easy infection germ and root-rot and damping off take place is if slightly carelessness can cause the failure of growing seedlings, so focus on " preventing doing harm to ".Promptly in coming up, every 8 days 800 times of import topsins of spray or partly measure the formula bordeaux mixture (0.5 kilogram of copper sulphate: 0.5 kilogram of quicklime: 100 kg of water) spraying, to seedling stem and blade back, foliage-spray.Two kinds of medicines are used alternatingly.
4., intertill and clean tillage, fertilising: during seedling growth, the attention weeding is loosened the soil, and improves the soil aeration condition.The weeding principle is: remove little, remove early, except.Seedling growth topdresses in earlier stage, and based on nitrogenous fertilizer, phosphate fertilizer, the rare night soil with 10% also adds 0.4 kilogram of urea preparation, executes once every first quarter moon, stops fertilising mid-September, and the cool canopy shading screen is removed, and uses but frame stays the coming year again.
5., seedling replanting: as irregular because of sowing, it is overstocked or rare excessively to cause nursery stock to distribute, nursery stock reach two leaves wholeheartedly after, the time to mid-June, must be carried out Nursery stock transplanting for by the end of May, a close benefit is rare.Transplanting method is: select to transplant behind overcast and rainy or the rain, cover liver moss after, clear water drenches the root and stem of certain plants.
6., biennial nursery stock management: after annual qualified seedling is used for afforestation.Reserved bed seedling needs in summer the cool canopy frame to be removed pavement and weeds all around well and in time, thin and weak seedling is strengthened to topdress grow promoting.
More than by meticulous experiment management, one year seedling is up to 15～30 centimetres, and biennial height of seedling reaches 50～80 centimetres, reaches 100 centimetres on a small quantity, 0.6 centimetre of seedling bar bar footpath ￠, and the per mu yield nursery stock reaches 60,000 strains.
Two, cultivation afforestation: cultivation, promptly plant trees, plant trees i.e. artificial afforestration.
(1), planting site is selected: select height above sea level more than 800 meters, soil layer is deep fertile, venting and water permeable, the mountain region of illumination abundance.
(2), nursery stock is selected: select and gave birth to healthy and strong, not damaged nursery stock in 1 year, one year seedling bar bar footpath ￠ is more than 0.3 centimetre, and is high more than 20 centimetres.
(3), land preparation mode: cultivate whole ground entirely, dig the cave and plant, 30 centimetres of chamber, cave specification 50 cm x 50 cm x, 1.0 meters * 1.0 meters of seeding row spacings.
(4), plant time and nursery stock handled: the time of planting was advisable with early spring winter Mo, and the survival rate height can reach more than 95%. accomplish when planting that root relaxes, seedling just, having peace of mind. it is preceding with 100 * 10 to plant
-6The ABT rooting powder solution adds glucose (it is 1% that glucose is joined back concentration) and soaked root 30 minutes.
(5), tending [after young plantation: connect and comforted 3 years, annual hoe is comforted, cutter is comforted each once.Hoe is comforted for 5～June and is carried out, and cutter is comforted for 8～September and carried out, and reaches weeding, loosens the soil, trains the root and stem of certain plants, expands cave passband purpose.Annual after 3 years according to the assorted growing state of irritating in the woods, comfort once in conjunction with fertilising.
(6), fertilising: afforestation need not applied fertilizer then, and annual every strain sealing fertilizer was 0.05 kilogram from 1 year, and punching is spreaded manuer in holes.Began to adopt ring tree trench digging deep placement on the 4th year, 0.1 kilogram of every strain.
Embodiment 2, and the method for planting southerm yew of present embodiment is the following step:
One, grows seedlings: cuttage and seedling culture
(1), transplants a cutting and select: use and sprout branch or treelet annotinous branch, require the branch stalwartness full, preferably be with young sprout then.Long 15～20 centimetres of plugged ear, base portion should be with old branch long 1.0～1.5 centimetres, thick 0.2～0.5 centimetre of base.
(2), the slotting machine setting: select that the water source is convenient, ground, garden is done on the ground in leeward cool place, slotting machine is made into wide 1.2 meters, the composite soil of yellow soil and thin river sand pad on, yellow soil is 1: 1 with the ratio of river sand carefully, in order to water conservation, breathe freely.20 centimetres of the height of bed will sparge bed surface with 0.4% liquor potassic permanganate after matrix is paved, and seal 1～2 day.
(3), plugged ear handles: from transplanting a cutting the plugged ear that shears off, base portion all is cut into horse ear shape, and tears off blade on 5～8 centimetres of branches in bottom with hand, manages behind the plugged ear base portion per 100 and is bundled into 1 bundle, and base portion immerses 100 * 10
-6In the ABT6 rooting powder solution 4 hours, average 1 gram root-inducing powder was handled 6000～8000 Chinese yew plugged ears.The plugged ear base portion dries slightly before the cuttage.
(4), cuttage and management: cutting time is 6～August.Punch 9 centimetres of hole depths, 8 centimetres of seeding row spacing 4 cm x before the cuttage with bamboo let, insert the plugged ear bar until the blade place along cutting hole, after sticking with one, be sprayed onto cutting hole and the disappearance of plugged ear suture, at once film be covered on the little shed with the pouring of 25% carbendazol wettable powder, 0.09% solution.Seedling bed temperature remains on 20～28 ℃, and humidity is 85～90%.Temperature is too high will in time ventilate, and humidity is crossed low should in good time the water spray, and matrix keeps moisture state, does not show Bai Weidu with the surface, can not be wet excessively, otherwise the easily mashed dead seedling of root.Cool canopy will be put up in the slotting machine top, light transmittance 30～40%, and canopy is high 1.8 meters, is convenient to management.After the nursery stock cuttage, note timely weeding, in order to seedling growth.About cuttage 1 month, part plugged ear base portion expands, and after 2～3 months, forms obvious visible callus lines, 3～8 at the dimly visible milky tip of a root.Do not form the cutting of callus, the young sprout of sprouting is withered, and the part of burying all is pitchy, and cortex separates; After 4～6 months, be the exhibition root stage, every strain has 5～10 of roots, long 4～6 centimetres of root, and the innovation growth is accelerated, and it is dark green that the leaf look changes. reach more than 85% 5～7 centimetres of new then shoot elongations by this method cuttage survival rate.The weather arid time is noted the drought resisting of spraying water, and the best incorporated fertilising is advisable with urea or efficient compound fertilizer solution with 0.4%. 1 year spring portable, further cultivate into strong sprout.
