Description

Four seasons gold (red) leaf glossy privet cuttage and seedling culture method

Technical field: four seasons gold (red) leaf glossy privet cuttage and seedling culture method relates to plant asexual multiplication technology, is specially the cuttage technique of Ligustrum plant.

Background technology: Oleaceae Ligustrum (Ligustrum) plant is urban road and flower garden greening tree and shrubs seeds commonly used, shrub is extensively planted and makes hedgerow, but the color and luster of these seeds is single, ornamental value is less, do not fall leaves and shrub four seasons gold (red) the leaf glossy privet that should make hedgerow is not only evergreen throughout the year, and the young leaves that grows is golden yellow and orange red, and very bright-coloured, ornamental value improves a lot; Do not make seeds always but still have because of this kind, can not seminal propagation, promptly use seminal propagation, seed is preserved difficulty, and influence is grown seedlings; And the bright-coloured leaf look of seeds quite is subjected to liking of people, and the demand of urban afforestation simultaneously constantly increases again; Therefore, necessary accelerates multiplication speed is made the demand of hedgerow seeds to satisfy people's gold to the leaf look bright-coloured (red) leaf glossy privet.Cuttage is a kind of effective asexual reproduction method, and still how improving cuttage survival rate of four seasons gold (red) leaf glossy privet and the output of raising unit are cuttage nursery stock then is the problem that the present invention need solve.

Summary of the invention: the present invention is intended to propose a kind of big density, brachyplast, shallow slotting cuttage and seedling culture method to solve the problems referred to above that four seasons gold (red) leaf glossy privet is grown seedlings and exists.

The foregoing invention purpose is achieved through the following technical solutions:

Four seasons gold (red) leaf glossy privet cuttage and seedling culture method comprises the management of adopting after fringe, cuttage and the cuttage, the plugged ear of cuttage collection is the branch with 1～3 joint, length 2～4cm, the degree of depth of cuttage is between 1～3cm, the density of cuttage is 4cm * 1～1.2cm, and it highly is the shed that shades of 2～2.3m that slotting machine is built, simultaneously the bed surface covered with plastic film, its spatial altitude is at 40～50cm, for the first time take off film in 5～15 days after the cuttage, and water permeablely, spray soup; The time of for the first time taking off film, the summer was inserted in after the cuttage 5～7 days, spring, autumn sowing after cuttage 7～10 days, and the winter was inserted in after the cuttage 10～15 days.

Be described in further detail the present invention below.

The preparation of slotting machine: the present invention uses the cuttage of soil bed under field conditions (factors), the wide about 1.2m of slotting machine, bed surface is spread the yellow soil of a bed thickness 3～5cm, adopt the following yellow soil of plow layer to make slotting machine soil, not only good drainage and air capacity of soils can be arranged, moisture capacity is also stronger, and yellow soil to contain pathogen few, be unfavorable for the germ activity again, therefore be beneficial to and take root, can improve cuttage survival rate.The shed that shades that shading screen is made should be built in the slotting machine sky, and height is convenient to bookkeeping between 2～2.3m, and this shed that shades not only can shade, be incubated, and can keep plugged ear to absorb dew where necessary; After slotting machine soil is gone in the plugged ear cuttage, also answer covered with plastic film on the slotting machine, make support with bamboo chip, the spatial altitude that makes film and bed surface is 40～50cm, so not only can improve subsurface temperature, and can keep the moisture content of slotting machine soil, can also prevent weeds propagation and widespread to a certain extent.

The collection of fringe bar: cuttage is generally carried out having the branch of dew for good in the morning with the collection of fringe bar, when being grown slightly in the need holding time, the fringe bar can not wilt, and also effective to the raising of cuttage survival rate; The general fringe bar of gathering can be the old branch of lifes in 1 year 2 years, but is good with old of giving birth to then, and should have blade; The length of branch has 1～3 joint to get final product between 2～4cm, and the fringe bar can be with the tip, also can not be with the tip, and such parent's branch can many fringe bars of clip, fully guarantee the fringe bar amount that big density cuttage is required; The system of cutting is during plugged ear, and the upper end otch is away from the leaf segment position, and clip nearby on leaf segment can tiltedly be cut as far as possible, also can straight snips.

Cottage method: the density of cuttage, depth relationship survive and later growth to four seasons gold (red) leaf glossy privet plugged ear, also are related to the effect of the saving and the cuttage of plugged ear material.

Four seasons gold (red) the leaf glossy privet cuttage and seedling culture method that the present invention proposes adopts shallow inserting, and 1～3cm gets final product in the fringe bar insertion bed soil of 2～4cm length, and oblique cutting, straight cutting all can; The density of cuttage is line-spacing 4cm, spacing in the rows 1～1.2cm, but i.e. 2000～2500 of every square metre of cuttage fringe bars, and this is the Fundamentals that improve unit are cuttage and seedling culture output.

Before the cuttage, irrigate the whole good native water of bed, drenched soil is convenient to cuttage, can not injure the fringe bar again; The cuttage of a bed soil is preferably in one day and finishes, and can not finish the cuttage of bed soil in one day, the plugged ear that cuttage is good should be watered repeatedly, and build film temporarily, does not fall leaves to protect plugged ear, and is injury-free; All cuttages intact after, the monoblock slotting machine be watered once permeablely, build film then.

Management after the cuttage:

The shed that shades that cuttage and seedling culture method of the present invention has adopted shading screen to make, can not only suppress the bed surface evaporation, keep slotting machine moisture, and can suppress plugged ear excessively rising, prevent to wither, thereby raising survival rate, can also play abirritation to the strong illumination that obstruction is taken root, especially can also prevent the abnormal high temperature that occur summer; The present invention has adopted plastic film to cover bed surface simultaneously again, is beneficial to further maintenance moisture and temperature again.The cuttage and seedling culture method that the present invention proposes, most critical is the time of taking off film for the first time in its management, because the cuttage of four seasons gold (red) leaf glossy privet can be in the spring, summer, autumn, carry out in arbitrary season in winter, but fringe bar for the Various Seasonal cuttage, it is vital scientifically grasping and taking off the film time for the first time, take off film and not only be beneficial to plugged ear acquisition dew, and take off and water once behind the film permeable and with the topsin of 0.6～0.8% concentration, any sprays once in carbendazim or the ground bacterium spirit, find that damaged by vermin will spray acephatemet, again sprinkling water once again before the epiphragma, so both can keep the skin wet for the growth of four seasons gold (red) leaf glossy privet seedling, can rinse out mould and control mould and insect again, spring, the fringe bar of autumn sowing is taken off the film time for the first time and was carried out in 7～10 days after cuttage, slotting fringe bar of summer is taken off the film time for the first time and will be done sth. in advance, because the summer is inserted the temperature height, therefore should be after cuttage carry out in 5～7 days; It is low that winter is inserted temperature, takes off the film time for the first time and can postpone after cuttage and to carry out in 10～15 days; The fringe bar that summer inserts, easily mildew as finding that branch has mould, can be taken off film 2～3 times continuously; General each film of opening carries out between the lights, and the next morning is built film again.After cuttage 30～60 days time of throwing off film, spring can be thrown off film after inserting and growing seedlings 40 days～50 days, the summer autumn sowing is grown seedlings and was thrown off film at 30～45 days, and the winter inserts and to throw off the film time at 50～60 days, after throwing off film, execute nitrogenous fertilizer one time, the whole cuttage and seedling culture time of four seasons gold (red) leaf glossy privet is 2.5～4 months.80～90%, the cuttage in every mu of ground can be cultivated 60～800,000 strains of four seasons gold (red) leaf glossy privet seedling, has solved people gold (red) the leaf glossy privet to the leaf look bright-coloured like this and has made the problem of hedgerow seeds wilderness demand with the survival rate of seedling of the inventive method cuttage.
