Description
Technical field
The present invention relates to utilize annual Chinese red autumnal leaves poplar to put in order strain winter protection wintering method.
Background technology
The existing technical disadvantages that the whole strain of Chinese red autumnal leaves poplar is survived the winter: 1, Chinese red autumnal leaves poplar plant all can not safe overwintering in three provinces each big city northeastward; Only rely on artificial winter protection; Utilize mid-October in autumn cornstalk around tree, to tie and weave into hedge, set up the air partition that is higher than plant.Or with straw rope volume do, with straw parcel trunk and major branch winter protection.2, not winter protection is survived the winter, the acrial part formation deadwood of all freezing to death then, and spring pruning went deadwood to sprout again from root in 1 year, formed the big shrub of no trunk, be difficult to form high megaphanerophyte, and newborn every year branch was freezed to death.The branch of freezing to death need cut off, otherwise the influence sight, time-consuming taking a lot of work.3, there is not special Chinese red autumnal leaves poplar winter protection antifreeze.Because the physicochemical property of plant self determines that plant is to the sensitivity difference of medicine, the plant cold resistance antifreezing agent of wide spectrum is used not obviously effect in the north to Chinese red autumnal leaves poplar, and present stage is not directed against the specific reagent of the anti-protection against cold and freezing conditions of Chinese red autumnal leaves poplar yet.China red autumnal leaves poplar is almost nil in each urban afforestation of Heilongjiang Province is used; Exactly because can't survive the winter; Seedling is difficult to find especially; The Harbin City only has several to do the Chinese red autumnal leaves poplar that nearly ten years age of trees of preserving are handled in winter protection, and through cold-resistant exercise for many years, the treetop end still has nearly half meter branch to be freezed to death in the winter time now.Therefore, Chinese red autumnal leaves poplar is difficult to promoted plant northeastward.The more little resistance of the age of tree is poor more, though the big cold resistance of the age of tree improves, transplants the cost height, and therefore the northerly application of Chinese red autumnal leaves poplar is less.
Summary of the invention
The object of the present invention is to provide the Chinese red autumnal leaves poplar in winter of a kind of remarkable enhancing cold resistance, can resist-27 ℃ of low temperature, do not freezed to death by complete stool winter, forms arbor, improves sight; And at breeding cultivation, the attendant is easy to use in the Landscape Application, practices thrift the whole strain wintering method of annual Chinese red autumnal leaves poplar of labour cost.Technical scheme of the present invention is: whole its raw material of the cold-resistant wintering method of strain (1) of a kind of annual Chinese red autumnal leaves poplar comprises: abscisic acid, clear water, abscisic acid is English to be called for short: ABA, the chemical formula of abscisic acid is: C
15H
20O
4(2) preparation: is 0.03% mixing with two kinds of materials by mass fraction: promptly get abscisic acid crystalline powder 0.3mg and add 1000ml water, mixing; (3) practical implementation step: at the beginning of 9 months autumns before the dormancy of Chinese red autumnal leaves poplar; The preparation that step (2) is obtained sprays whole strain blade with vaporific sprayer; After 15 days; Preparation with step (2) acquisition sprays whole strain blade once with vaporific sprayer again, and the preparation that obtain step (2) October carries out once whole strain again with vaporific sprayer and sprays i.e. announcement completion.China red autumnal leaves poplar is a kind of quick growing species of trees, and the year increment maximum can reach 170-180cm, so the lignification level is low, is easy to generate freeze injury.Abscisic acid is a kind of inhibition growing plants hormone, gains the name because of impelling leaves, and has the plant of making and get into resting state in advance, promotes that plant shifts to an earlier date the effect of lignification enhancement of plant resistance.Think through our experiment in several years; The spraying effect that is applied on the Chinese red autumnal leaves poplar of abscisic acid is different, perhaps sprays evening time if concentration is low, at the beginning of 10 months, sprays; Do not reach and make Chinese red autumnal leaves poplar shift to an earlier date dormancy to promote lignified effect, can not be cold-resistant; If the excessive concentration or the time that sprays spray in August in advance, Chinese red autumnal leaves poplar is fallen leaves early, and the light that will fall last years of a century in September has influenced its appreciation effect.Therefore; We are through spraying concentration and the experiment that sprays the time; Utilize the present invention can play and promote dormancy to improve degree of lignification, can not make its maintenance appreciation effect of falling leaves in advance again, reach the effect of Chinese red autumnal leaves poplar in winter safe overwintering Chinese red autumnal leaves poplar.Free growing in the winter time Chinese red autumnal leaves poplar can't be resisted-27 ℃ low temperature and complete stool freezes to death; And the Chinese red autumnal leaves Yang Quan plant height 170cm that utilizes this method only has the tip that freezes of 3-4cm in the top; But the continued growth in next year is unlikely to grow up to the shrub shape from the root sprouting, can continue to keep the arbor form.We are through time of the year when autumn changes into winter mensuration to Chinese red autumnal leaves poplar physical signs when temperature reduces, and the Chinese red autumnal leaves poplar of finding to spray abscisic acid is than the Chinese red autumnal leaves poplar of not handling, and the blade plasma membrane is passing through property relatively, and electrical conductivity on average reduces by 34.5%; Soluble sugar content on average increases 37.6% in the blade; Free proline content on average increases 44.8%, and variance analysis all reaches extremely significantly standard of difference.From the data show of physical signs, utilize the Chinese red autumnal leaves poplar of abscisic acid on the resistance index, all to significantly improve, and observed 3-4cm following branch in top not have freeze-drying, air-dry phenomenon 1 year spring.The present invention utilizes simple method, has improved the cold resistance of Chinese red autumnal leaves poplar, makes annual Chinese red autumnal leaves poplar need not block safety in the north and passes the winter, and can continued growth survival rate reach 97% later winter.Reach the annual Chinese red autumnal leaves poplar of maintenance and grown up to arbor, kept the purpose of whole strain appreciation effect.
