Abstract
The invention discloses a sowing propagation method for dawn redwoods. The method comprises following steps: (1) seed collecting; (2) soil preparation; (3) seed processing; (4) sowing; and (5) seedling management. In the step (1), cones of dawn redwood mother trees are collected in the year before sowing. In the step (2), sowing is performed in February in the sowing year; acidic sandy loam with pH being 4-6 is employed as the breeding field; and beds are made after the breeding field is ploughed and raked. In the step (3), seeds are soaked in 0.1% potassium permanganate solution or in the water at 28-32 DEG C before sowing. In the step (4), ditches are made in the beds and then drill sowing is performed. In the step (5), shade houses are erected on the beds after the seeds sprout. By employing the method, the propagation quantity and survival rate of dawn redwoods can be effectively increased and improved, dawn redwood seedlings can be outplanted and transplanted in a short period, and the transplanted seedlings grow well.
Description
Technical field
The present invention relates to a kind of seed propagation method of trees, particularly relate to a kind of seed propagation method of metasequoia, belong to agriculture trees and bring up technical field.
Background technology
Metasequoia is Relict Plant rare in the world, there is the title of vegetable kingdom living fossil, belong to fallen leaves megaphanerophyte, up to 35-41.5m, the diameter of a cross-section of a tree trunk 1.3 meters above the ground reaches 1.6-2.4m, trunk is logical straight, base portion often expands, bark grey, taupe or lead, and treelet is cleaved into platelet exfoliation, large tree is cleaved into strip and comes off, endothelium lividus; Branch is exhibition tiltedly, and sprig is sagging; Metasequoia happiness light, has certain salinity and alkalinity resistance, also can normal growth on the light saline land of salt content 0.2%.
Metasequoia trunk leads to straight elevator and pulls out, tree-like magnificence, autumn has set in, and posterior lobe coloured gold is yellow, be commonly used for urban afforestation, beautify park, garden or build riverine, river bank shelter forest etc., because metasequoia is to pernicious gas resistances such as the sulphur dioxide in air, there is contamination resistance, metasequoia also has the stronger ability absorbing and retaining dust simultaneously, and therefore, metasequoia is also usually used in the greening of industrial and mining area; Metasequoia material reddish tan, heartwood is purplish red, and material is light and soft attractive in appearance, can supply building, plate, papermaking, utensil processed, modeling type and interior decoration, is the good timber of shipbuilding, building, bridge, farm implements and furniture.
Therefore, the value of metasequoia is very high, but the breeding of metasequoia is at present mainly by cuttage cultivation, want first from clip cutting elite stand, and choose the cutting for the treatment of clip and clip length is uncontrollable, the survival rate of cuttage cultivation is lower, even if the metasequoia nursery stock becoming to survive, the survival rate that later stage transplants again also can be had a greatly reduced quality, and growth conditions is not good.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides a kind of seed propagation method of metasequoia, effectively improve the seed propagation survival rate of metasequoia.
The technical solution adopted in the present invention is:
A seed propagation method for metasequoia, is characterized in that, comprise the following steps:
(1) collect seed: pluck metasequoia elite stand cone between mid-October to mid-November of 1 year prior to seeding, cone airing is deviate from seed to fruit scale cracking;
(2) wholely: sow in the February in sowing year, do nursery with the acid sand of pH value 4-6, within 8-10 days, apply the mixture of fertilizer or superphosphate and quicklime before sowing to nursery, after plow harrow, do furrow;
(3) seed treatment: soak seed with the liquor potassic permanganate of 0.1% before sowing and rinse rear sowing with water; Or to sow after drying in the shade with the water soaking seed of 28-32 DEG C;
(4) sow: drilling of ditching on furrow, in ditch, cover Nutrition Soil 3-5cm thick, will sow in ditch on Nutrition Soil after seed and fine sand fusion, with yellow soil cover-seeding ditch, after planting at furrow upper cover straw, a spray water, and continue to keep ground moistening in furrow before emerging;
(5) seedling management: emerge more than 40% time remove straw, furrow put up cool canopy.
Further, in order to ensure the germination rate of metasequoia seed, emergence rate and the survival rate of plucking, the age of tree of metasequoia elite stand is plucked described in step (1) more than 35 years.
Further, in order to improve the fertility of soil, the weight applying fertilizer described in step (2) is per hectare 60-80 ton, and the weight of described superphosphate is per hectare 1.2-1.5 ton, and the weight of quicklime is per hectare 0.07-0.08 ton; Described fertilizer is one or both the mixture in compost or barnyard manure.
Further, in order to promote that the seed coat of metasequoia seed softens, increase permeability and imbibition ability, before the sowing described in step (3), immersion seed is the liquor potassic permanganate immersion seed 1-1.5h with 0.1%, and sows after rinsing 5min with the clear water of flowing; Or with the water soaking seed 8-10h of 28-32 DEG C pull out dry in the shade after sowing, the inhibitor such as metasequoia seed inclusion abscisic acid, acidulants are decomposed, improves the mobility of enzyme, and make complicated compound change soluble substance into, promote embryo development, improve percentage of seedgermination.
Further, in order to ensure the developmenting space of metasequoia seed in soil and the growing space after being unearthed, the furrow width 8-12cm ditched on furrow described in step (4), dark 8-10cm, ditch spacing 20-25cm.
Further, the Nutrition Soil described in step (4) comprises the baked wheaten cake fine earth of 95% and the calcium magnesium phosphorus of 5%, in order to promote the germination of metasequoia seed.
Further, also comprise the step of seedling furrow after the rain spreading fine earth after emerging described in step (5), keep soil from packing together, reduce moisture evaporation.
Further, in order to metasequoia nursery stock after ensureing to be unearthed is needed for the growth of Fast-growing stage, after emerging described in step (5), also comprise the step of topdressing, described in topdress as 2-3 time, and to carry out between 6-8 month then planting.
Further, remove described in step (5) straw be at the cloudy day or at dusk time carry out, avoid because of the sun beats down temperature higher time remove straw, injure the growth of metasequoia nursery stock.
Beneficial effect of the present invention is: by rationally sowing the metasequoia seed plucked, the seedling management of science, effectively improve the seed propagation survival rate of metasequoia, and transplant fast through the metasequoia outplanting that the present invention breeds, the growth result after transplanting is good.
