Abstract
The invention relates to an arborous Cercis canadensis seedling cultivation method, which is used for cultivating arborous seedlings by using bushy Cercis canadensis 'Forest Pansy'. The cultivation method provided by the invention has the advantages that the method is simple and easy to implement, the bushy tree form of the Cercis canadensis 'Forest Pansy' can be effectively overturned, completely novel arborous ornamental plants can be cultivated and the landscape promotion demand of garden green tree configuration and planting is met.
Description
Technical field
The present invention relates to a kind of method for cultivating nursery stock with that promotes afforestation trees and plant landscape need, especially a kind of method that purple bush plant type leaf Canada cercis is cultivated into arbor shape nursery stock, belongs to field of plant growing technology.
Background technology
Purple leaf Canada cercis is popular good color leaf seeds in the world at present, enters into just gradually people's the visual field, and in park, the place such as road, square, community, isolated planting, group planting, mass-planting all have outstanding landscape effect.But determined by hereditary factor, the Canadian cercis of purple leaf that adopts Sterile culture method to cultivate presents the shrub shape plant type that racemosus is grown thickly, and limits to a great extent its cultivation application in afforestation trees plant.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method that the Canadian cercis of purple bush plant type leaf is cultivated into arbor shape nursery stock, on the other hand, also relates to the success rate that how to improve the inventive method.In order to solve technical problem of the present invention, the present invention intends adopting following technical scheme:
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
One aspect of the present invention relates to the Canadian cercis method for cultivating seedlings of a kind of arbor shape, it is characterized in that comprising the steps:
The first step, selected full grains, the Canadian cercis seed that color and luster is vivid, to improve stock grafting affinity: in Yangzhou, Jiangsu, adopt the mode of wet husky mix, in deepfreeze 30-45 days under 3-4 DEG C of condition in February in early spring; In the time that the first transaction of a day's business of seed germination hole, plumule show money or valuables one carries unintentionally, turn the capable sowing of seedbed bar and cultivate the rootstock seedling that grows directly from seeds.
Second step, in November in autumn then, retains the central limb of upright growth, removes all the other growth limbs that root is grown thickly, and transplants land for growing field crops and cultivates graft stock: Gansu Province is wide 1.2 meters, Gansu Province is high 0.2 meter, and furrow is wide 0.4 meter, 0.8 × 1.6 meter of stock field planting strain, line-spacing.
The 3rd step, next year or the 3rd year spring, to the upright limb retaining apart from 0.4-1.2 rice, ground cutting strunk, the cultivar scion of the good purple leaf proterties of scion grafting; Upper cut must be smeared grafting wax sealing, in case scion dehydration is air-dry.Grafting period, the result of the test of continuous 3 years shows that early April is advisable, and can improve graft survival rate and reach more than 85%.
The 4th step, when scion germination and growth reaches more than 50 centimetres, adopt high branch grafting of cercis canadensis forest pansy servicing unit to fix, in case windbreak: the scion that annual typhoon season causes is lost up to more than 30%, adopts method of the present invention can reduce below scion damage rate to 6%.Fall foliage recession is except protection fixture.
The 5th step, the first tenday period of a month May late spring and sprout tillers emergence period early July in midsummer, remove stock sprout tillers by hand in time, keep independent trunk proterties, successfully cultivate arbor shape and view and admire plant type.The good plant type of the purple leaf of arbor shape Canada cercis also cultivate and stock sprout tillers remove in time relevantly, select suitable opportunity most important for the healthy growth of nursery stock.In the present invention twice of the first tenday period of a month in May and early July except sprout can effective guarantee nursery stock healthy growth.
The invention has the beneficial effects as follows: method for cultivating seedlings of the present invention is simple, enforcement is easy, the bush that can effectively overturn the Canadian cercis of purple leaf is tree-like, cultivates the arbor shape of novelty completely and views and admires plant type, meets the view lifting demand that afforestation trees plant.The technology of the present invention good operability, safe and reliable, is conducive to expand the Landscape Application scope of the Canadian cercis of purple leaf, Improve Efficiency, colourful ecology.
