Abstract

The invention discloses a grafting propagation method for Lagerstroemia indica Pink Velour. The method includes the steps of 1, selecting grafting time; 2, growing rootstocks; 3, collecting scions; 4, combining the scions and the rootstocks; 5, performing post-grafting management. The method has the advantages such that excellent ornamental characteristic of Lagerstroemia indica Pink Velour can be retained, seedling raising cycle is shortened for Lagerstroemia indica Pink Velour, the method is simple to operate, healing is fast after grafting, and survival rate is high.

Description

The propagation by grafiting method of a kind of U.S. red autumnal leaves crape myrtle

Technical field

The present invention relates to plant vegetative propagation field, be specifically related to the propagation by grafiting method of a kind of U.S. red autumnal leaves crape myrtle U.S. red autumnal leaves crape myrtle.

Background technology

U.S.'s red autumnal leaves Lagerstroemia machaka or dungarunga, garden-variety is shrub shape, and bark easily comes off, and trunk is smooth, and sprout is slightly four prismatic sepias, slightly becomes aliform, single leaf alternate or to life, nearly stockless; Ellipse or obovate, panicle raw newborn end of the branch then, and in 6～November of florescence, petard is red, and there is irregular incising at edge, and base portion has long pawl; Really 7～September of phase, November is ripe.The resistance of red autumnal leaves crape myrtle to sulphur dioxide, hydrogen fluoride and nitrogen, can suck pernicious gas.Propagation by grafiting is the conventional propagation method of U.S. red autumnal leaves crape myrtle, but the existing propagation by grafiting method cycle is long, and survival rate is relatively low.

Summary of the invention

Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides the propagation by grafiting method of a kind of U.S. red autumnal leaves crape myrtle U.S. red autumnal leaves crape myrtle.

Technical scheme: for achieving the above object, the propagation by grafiting technology of a kind of U.S. provided by the invention red autumnal leaves crape myrtle, comprises the following steps:

1) select stock: grafting time be annual late May to early June, select the short crape myrtle in 1 ~ 3 centimetre, 1 ~ 2 year dried rhizome of rehmannia footpath, the major branch growing fine is done stock;

2) clip scion: choose U.S. red autumnal leaves crape myrtle and grow stalwartness, the raw semi-lignified branch then that axillalry bud is full, avoids high temperature and rainy weather.Branch will be with adopting with connecing, and can not complete the same day answers stored refrigerated;

3) scion is combined with stock: at liftoff about the 15 centimetres places of stock, in selecting step (2), roughly the same or slightly thick branch is cut off with scion diameter, 3 ~ 5, leaf below reservation stock grafting position, be used to provide nutrition, the cross section central vertical rip cutting that stock is cut off reaches 2 centimetres of left and right deeply, scion is cut into 2 ~ 3 centimeter length, and has the footpath section of a full bud of a blade.The neat bud truncation in upper end, the lower end cutter that tilts from the flat bud of the reverse side lower end of bud, is switched to xylem, and the degree of depth reaches 1/3 left and right of branch, must not surpass 1/2. straightly to next cutter again, makes scion face reach xylem, and the visible medulla of base portion is for spending; Subsequently, positive lower end at bud, the reverse side of long bevel is cut a short bevel that is about 1cm, make scion be horse ear shape, it is smooth clean that bevel is made every effort to, and the scion shearing inserted immediately to the mouth of splitting of stock, makes both both sides or form layer on one side to aim at, then with plastic strip, graft union is all tied up sternly together with clip in scion, only expose blade and eye;

4) managing after grafting: connect rear management: connect latter about 10 days and check and survive, all scion leafs are fresh, and bud green being of buddering survives, and can solution tie up when scion is newly slightly extracted 3～5cm out; Strengthen water and fertilizer management, prevention and elimination of disease and pests in time.

Further, the managing after grafting described in described step 4) is, after connecing, pours water immediately, keep soil moisture sufficient 1 week; Subsequently, medication in time prevents that damage by disease and insect from occurring.

Beneficial effect: the present invention can keep the good characteristic of viewing and admiring of U.S. crape myrtle, has shortened the growing-seedling period of U.S. crape myrtle, and method is easy and simple to handle, and graft union is fast, survival rate advantages of higher.

Embodiment

Below in conjunction with embodiment, the present invention is further described.

A propagation by grafiting technology for U.S. red autumnal leaves crape myrtle, comprises the following steps:

The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.

Claims

The propagation by grafiting method of 1.Yi Zhong U.S. red autumnal leaves crape myrtle, is characterized in that: comprise the following steps:

1) select stock: select the short crape myrtle in 1 ~ 3 centimetre, 1 ~ 2 year dried rhizome of rehmannia footpath, the major branch growing fine is done stock;

2) clip scion: choose U.S. red autumnal leaves crape myrtle and grow stalwartness, the raw semi-lignified branch then that axillalry bud is full;

3) scion is combined with stock: in liftoff 15 centimeters of stock, in selecting step (1), identical with scion diameter or slightly thick branch is cut off, 3 ~ 5, leaf below reservation stock grafting position, the cross section central vertical rip cutting that stock is cut off reaches 2 centimetres deeply, scion is cut into 2 ~ 3 centimeter length, and there is the footpath section of a full bud of a blade, the neat bud truncation in upper end, lower end is cutter from the flat bud of the reverse side lower end inclination of bud, be switched to xylem, the degree of depth reaches 1/3 ~ 1/2 of branch, more straight to next cutter, the scion face of making reaches xylem, and the visible medulla of base portion is degree; Subsequently, at the reverse side of the long bevel of the positive lower end of bud, cut the short bevel of a long 1cm, make scion be horse ear shape, it is smooth clean that bevel is made every effort to, the scion shearing is inserted immediately to the mouth of splitting of stock, make both both sides or form layer on one side to aim at, then with plastic strip, graft union is all pinioned together with clip in scion, expose blade and eye;

4) managing after grafting: connect inspection in latter 10 days and survive, all scion leafs are fresh, and bud green being of buddering survives, and can solution tie up when scion is newly slightly extracted 3～5cm out; Strengthen water and fertilizer management, prevention and elimination of disease and pests in time.
