Background technology
Southern magnolia, another name: bull bay, evergreen magnolia.Classification system: Magnolia Grandiflora Linn.For Magnoliaceae, magnolia.Originate in America, North America and the Yangtze river basin of China's Mainland and areas to the south thereof.The north, as the ground such as Beijing, Lanzhou is introduced a fine variety.For viewing and admiring, flower is containing aromatic oil.Very big owing to blooming, it is similar to Flos Nelumbinis, therefore also known as " evergreen magnolia ", can be used as medicine, it is possible to do roadside greening.Evergreen magnolia tree performance state is grand, and the wealthy shade of leaf is dense, and flower is full of fragrance like Flos Nelumbinis, for beautifying seeds, and the wind resistance of resistance to cigarette, the toxic gas such as sulfur dioxide there are is stronger resistance, can be used for purifying air, protect environment.
At present, most breeding method is all to carry out by the way of grafting, but is often affected by external environment at scion with the grafting of stock during grafting, modal be exactly antibacterial infringement and cause grafting failure.
Summary of the invention
It is an object of the invention to provide a kind of southern magnolia gardening Formregelung breeding method, there is the grafting success rate that improve at scion and stock grafting.
The above-mentioned technical purpose of the present invention has the technical scheme that a kind of southern magnolia gardening Formregelung breeding method, comprises the following steps:
Step one, nursery selects: nursery lot select smooth in physical features, loosing soil porous, soil property are fertile, soil ph value is 6.4-6.9, soil layer is deep, sunny, water source and the good plot of irrigation condition；
Step 2, stock is cultivated: the seed of Magnolia Delavayi is put into immersion 1.5h in the solution of MET0.5mg/L；
Step 3, stock grows: in spring, by the planting seed in step 2 on the nursery of step one, until seed growth become footpath, ground more than 0.8cm and robust growth, endanger without disease pest time as stock；
Step 4; seedling grafting: when the tree seedling in step 2 grows to the stock becoming step 3 autumn of First Year; southern magnolia is taked to make scion with the healthy and strong branch of terminal bud; scion is inserted otch by the position cut-grafting method at stock distance ground more than 5cm; then at the grafting of scion and stock, it is coated with layer protective layer, and tightens by plastic ties；
Step 5, repaiies Seedling: after the one and a half months after step 4 completes, and is erased by the side shoot of below the southern magnolia 30cm after scion；
Step 6, lateral bud processes: in the mid-March of Second Year, is pinched by the trunk of southern magnolia, promotes the collateral generation of trunk；Until side shoot is pinched by the JIUYUE of Second Year, promote side shoot separates secondary side shoot；
Step 7, selects branch: tiny, mixed and disorderly, the incomplete side shoot of shoot and leaf growth are cut off, and retains the side shoot that shoot and leaf growth is luxuriant；
Step 8, modeling scissors: according to cylindrical shape need, with near the dense side shoot on the side shoot of trunk as radius, be trimmed to downwards cylinder from top；
Step 9, prunes repeatedly: repeat step 6 to eight.
nullBy the performance that selected in nursery, optimum environment matches with the growth of Magnolia Delavayi，Enable Magnolia Delavayi to play the strongest tissue growth ability and carry out effective fast-growth，The Magnolia Delavayi seed soaked in the solution of MET0.5mg/L had stronger rootability，Then plant in nursery and cultivate，Its Magnolia Delavayi seed is because having stronger rootability and then improve the survival rate of seed，The branch of southern magnolia is grafted onto by Magnolia Delavayi as stock after，It is coated at the scion grafting with stock by protective layer，Effectively prevent antibacterial from encroaching at grafting，Improve the grafting success rate at scion and stock grafting，And tightened by plastic ties，The incision at stock enabling scion stable grows，The subsequent purpose repairing Seedling is to remove the side shoot being positioned at bottom on trunk，Make side shoot will not intercept the nutrient on trunk，Nutrient is enable more fully to transport the top of trunk for trunk and the germinating of the side shoot of more than 30cm，And then become dense branch and leaf to lay the first stone for late growing stage，Process through lateral bud and select branch，Draw well-grown.The side shoot being thick with leaves, then after modeling scissors, just can obtain branch and leaf gather there is the cylindrical southern magnolia of sight.
Further, in step 4, the anvil bud of stock is removed, only stay the only stake of smooth stock, split the otch of deep 3-4cm under stock mediad with cleft grafting cutter, 2-3 bud is stayed in scion, and lower end is whittled into contract type, the long 2-3cm of bevel, inserts scion at the otch of stock, and to good cambium layer.
By the anvil bud of stock is removed, and the otch of deep 3-4cm is split in stock central authorities, the nutrient making stock can sufficiently be supplied to incision to scion, and then enable scion to obtain nutrient after grafting timely, and the notch depth of 3-4cm can be fully contacted with the bevel of scion and it firmly be clamped, the cambium layer of its scion is the most relative with the cambium layer of stock, makes stock and scion quickly be combined into scion and provides nutrient, improves the success rate of scion.
Further, at the scion grafting with stock otch, the protective layer of cladding is Moisture absorption cloth, and on Moisture absorption cloth, uniform adsorption has Bordeaux mixture.
By being coated with Moisture absorption cloth at the grafting of scion and stock otch, and on Moisture absorption cloth, adsorb Bordeaux mixture can play the effect of sterilization, and then can also prevent from the antibacterial of external environment from entering at grafting while killing antibacterial at grafting stock and scion are caused damage, and then improve scion and stock directly in conjunction with success rate.

Within each 3-4 days, dropping Bordeaux mixture can make Moisture absorption cloth be in moistening state, and then scion and stock can be close to, prevent antibacterial from entering at grafting, and on Moisture absorption cloth, maintain moistening Bordeaux mixture, can effectively sterilize at grafting, improve the survival rate combined between scion and stock.
Further, 30cm twig once is erased by being manually held on side shoot by step 5, and side shoot from semi-lignified grow into lignified during repeatedly carry out bud picking.
By the twig on side shoot is erased, make twig near one section of portion on ground by having extra twig by the Nutrient Absorption on trunk, and then enable nutrient to be transported to the top of trunk, after pinching for trunk, the growth of side shoot provides enough nutrients, improve the germinating of trunk side shoot and the growth of stalwartness, lay the first stone for the dense branch and leaf that grow on side shoot.
Further, in step 6, is pinched in the position of trunk distance 50cm of southern magnolia, remove apical dominance, promote collateral generation.
Position by trunk distance 50cm at southern magnolia, the most also it is about month before trunk is in Second Year spring, now reason collateral generation, and the bud of side shoot is fresh full, is in the trophophase of rudiment, is thus advantageous to the growth stage of side shoot, and the trunk after pinching loses apical dominance, its nutrient can directly feed side shoot and supply collateral generation, and then makes can grow on trunk dense side shoot and branch and leaf, beneficially pruning during moulding.
Further, when collateral generation goes out 8-9 sheet branch and leaf, whole of growth is mixed and disorderly, underfed side shoot carries out cutting, retains dense side shoot.
By side shoot being carried out selectively cutting and reservation, by some dysplasia, it is unfavorable for that the side shoot of later stage modeling scissors crops, retain and grow preferable side shoot, the side shoot broken down is made to will not continue to absorb the nutrient on trunk, and then ensure well-grown collateral generation, on the other hand the side shoot bud being also beneficial on trunk regrows, in order to southern magnolia grows dense branch and leaf, beneficially modeling scissors.
Further, the side shoot of below 50cm, when trunk reaches more than 100cm, is cut off by the pruning of cylindrical conformation.
By 50cm side shoot once is removed, these side shoots can be made to cut off without drawing nutrient, enough nutrients are provided for the growth that trunk is lasting, and be conducive to carrying out extracing or spraying herbicide by the weeds of trunk surrounding, the nutrient enabling soil more supplies the root system of trunk, and then ensures that root system is obtained in that enough nutrients so that trunk and collateral generation.
Further, when the shortest collateral generation to 60cm, select the denseest side shoot to prune the radius of cylinder the most, be as the criterion with this radius and carry out pruning out cylinder.
By carrying out pruning cylinder for radius with the shortest side shoot being thick with leaves, make being thick with leaves of the cylindrical southern magnolia after pruning, do not have significant portion of light transmission, there is good sight.
nullIn sum，The method have the advantages that by providing planting soil from the Magnolia Delavayi tree seedling that is prepared as in nursery，And the Magnolia Delavayi seed through MET solution soaking has stronger taking root property and improves the survival rate of seed，The Moisture absorption cloth of the dropping Bordeaux mixture being coated with at the grafting of scion meeting stock when grafting，Make be susceptible to the infringement of antibacterial at grafting and can sterilize，Scion is made to be protected with the growing environment of stock，And the anvil bud of stock is removed，Nutrient is enable fully to be supplied to scion，So that scion can grow in the environment of good at enough nutrients，And then improve the grafting success rate at scion and stock grafting，Just lateral bud process and selection and modeling scissors is carried out again after scion and stock success grafting，While making the growth that trunk can continue and collateral generation can be promoted，And grow dense branch and leaf，The cylinder being finally trimmed to the tight green shade of branch and leaf has the gardening southern magnolia of sight.
