Abstract
The invention provides a common poinsettia cutting method. The first year growth common poinsettia branch is used as ears-picking object. One month before picking ears, the content of maternal plant nutrient liquor is adjusted, so that the content of the nitrogen fertilizer is 0.3g/L, the content of the phosphor fertilizer is 0.5g/L and the content of the potassium fertilizer is 0.5g/L. The maternal plant nutrient liquor is directly irrigated into the pot for planting maternal plant and the individual plant fully receives the irradiation at 20000-30000lux. When selecting cutting branch, the adnation new shoot of common poinsettia is selected. The soddy soil is placed in plug and drenched before cutting. The uperized red mud is mixed with heteroauxin in ratio of 1:1 in pasty state, thus the root-taking agent is formed. During cutting, the ears dip the root-taking agent at 20-25 degree. After cutting, the humidity keeps 70-80% and the cutting substrate is soddy soil.
Description
Technical field
The present invention relates to the plant cultivation method field; Field of floriculture methods particularly.
Background technology
It is red that poinsettia (Euphorbia pulcherrima) has another name called Christmas tree, poinsettia, ivory.Be Euphorbiaceae Euphorbia evergreen shrubs.Originate in Mexico, many introducing new breeds from the U.S., Europe etc. of China done potted flower culture.Be characterized in dwarfing of plant, branchiness is strong, flower type, pattern U.S., and blade difficult drop-off.It occupies certain share on the flowers market of China at present, becomes the potted flower kind of small investment, high efficiency.Morphological feature is, the brown and tender stem green of stem look ash is smooth, contains white milk.The leaf alternate, ovum shape ellipse to shape to lanceolar, long 10cm-20cm, leaf margin tool cognate, shallow splitting or full edge, the blade under the stem poppyhead preface is narrower, is bracteal, usually full edge takes on a red color when blooming.The cup-shaped inflorescence that give birth on the top is sympodium to be arranged, the involucre light green, and the yellow body of gland of tool, whole inflorescence is that red bract is set off.Happiness warm and moist and sunny, not tight to the soil requirement, and growth is better in the fertile sandy loam of subacidity (PH6).Not cold-resistant, need go into the greenhouse before the frost, it is best keeping 16 ℃-18 ℃.When being lower than 15 ℃ then the leaf Huang come off, should keep away the high light direct projection summer.The flower bud differentiation thermophilic is 15 ℃-19 ℃.Poinsettia is a short day property plant, about 10 hours sunshine, the temperature that is higher than 18 ℃ can bloom.18 ℃ of-20 ℃ of illumination every day 8 hours-9 hours, blade can be bloomed in red approximately 50 days.
At present, poinsettia is many with spray or dormant wood cottage propagation.But, cause the poinsettia cuttage survival rate low because the unreasonable use of cutting medium and cuttage process is lack of standardization.And rootage duration is long, even bad root phenomenon occurs.
Summary of the invention
The present invention provides a kind of medium of suitable poinsettia cuttage for solving the technical problem that exists in the known technology, in order to improve the cuttage survival rate of poinsettia, improves the rooting rate of poinsettia.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: the cottage method of poinsettia, it is characterized in that: with annual poinsettia branch as adopting the fringe object, adopting fringe preceding 1 month, the maternal plant nutritive medium contg is adjusted into: contain nitrogenous fertilizer 0.3g/L, the mixed liquor of phosphorus, each 0.5g/L of potash fertilizer, directly water in the basin soil that is filled in the plantation maternal plant, and allow plant fully accept illumination, illumination remains on 20000-30000lux; When choosing the cuttage branch, should select poinsettia adnation young sprout, turfy soil is positioned in the cave dish, the water of before the cuttage turfy soil being drenched, add heteroauxin with red soil through high-temperature sterilization, ratio with 1: 1 mixes pasty state, as root-growing agent, during cuttage plugged ear is dipped in root-growing agent, the temperature of cuttage is advisable with 20～25 ℃, after the cuttage, humidity remains on 70～80%, and cutting medium is a turfy soil.
Advantage and good effect that the present invention has are: adopt cottage method of the present invention, make poinsettia branch rootage duration shorten to 15 days by original 26 days; Survival rate has brought up to 98% by 60%.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, iron bed, draw-in groove, cave dish disinfection to putting usefulness before the cuttage.The available common disinfectant spraying disinfection of iron bed, available 0.3% to 0.5% liquor potassic permanganate soaking disinfection is coiled in draw-in groove, cave.Carry out the cuttage operation by day and the time sunshade net of working region should be opened, use red soil through high-temperature sterilization to add heteroauxin and mix pasty state, as root-growing agent with the ratio of 1:1.During cuttage plugged ear is dipped in root-growing agent, the degree of depth that plugged ear is dipped in root-growing agent is about 1 centimetre, and the cuttage degree of depth is (cutting length is about 5 centimetres, insert matrix 1.5 centimetres) well to expose whole tender shoots just.The temperature of cuttage is advisable with 20～25 ℃.Surpass 25 ℃ and just cause transplanting a cutting germination excessive growth easily.In the cottage propagation, the dehydration that causes transplanting a cutting in order to reduce the blade transpiration, just needing increases air humidity, and humidity remains on 70 ~ 80%.But when Water-and mist-spraying increased air humidity, moisture did not water too much, as long as keep the blade face that water droplet is arranged, even matrix slightly drying help taking root.If moisture waters too much, matrix is wet excessively, can cause the poinsettia lower cut to rot and can not normally take root.
If carbohydrate containing height in the common poinsettia stem, then taking root is easier to, and the branch softness has the too much maternal branch of excessive growth phenomenon or nitrogen fertilizer application, and cuttage root-taking is difficulty, and lower cut rots easily.Therefore should note: the first, adopt the fringe phase poinsettia, maternal plant will reduce amount of application of nitrogen fertilizer, suitably enriches phosphorus, potash fertilizer, and nitrogenous fertilizer is reduced to 0.3g/L by 0.4g/L, and phosphorus, potash fertilizer are increased to 0.5g/L by 0.4g/L.(in a premium on currency, add in turn nitrogenous fertilizer 0.3g, phosphate fertilizer 0.5g, potash fertilizer 0.5g be mixed with mixed liquor directly water be filled in the basin soil).And allowing plant fully accept illumination, illumination remains on 20000-30000lux, suppressing prosperous nourishing and growing, thereby helps the accumulation of carbohydrate; The second, when choosing the cuttage branch, suitable branch is made plugged ear should to select the poinsettia nutritional status, as the adnation young sprout, and does not select the major branch top tip of tender succulence; The 3rd, adopt the placing direction that fringe often rotated the poinsettia maternal plant in preceding 20 days, allow whole plant all accept illumination fully, sprout the full lateral buds that enrich more, so that being provided, more cutting chooses chance.Easier the taking root of cutting of being got on than adult plant in cutting obtained on the poinsettia children seedling in age.The poinsettia maternal plant just needs after general 2～3 years to eliminate, and introduces again then.Because poinsettia also causes deterioration of variety easily behind cottage propagation repeatedly.At first, the age of poinsettia is the strongest with the regeneration capacity of annual branch (being annual shoot).That is to say that epicormic branch cuttage survives than easier the taking root of cuttage.Secondly, though poinsettia can take to transplant a cutting cuttage any period in 1 year, different time is adopted cutting and is had a significant impact taking root.Leaf semi-lignified cuttage of poinsettia band and epicormic branch cuttage all carry out in the season of growth, but young sprout takes to transplant a cutting the sure optimum efficiency that obtains when certain maturity is arranged.Cutting medium is (5 ~ 20mm) turfy soil optimums.
Observe the cuttage poinsettia table of taking root
