Abstract

The invention provides a method for cultivating plants with color-variable leaves which are obtained through multi-generation grafting by using populus bolleana, populus simonii, populus marilandica and populus wilsonii as basic species. The method comprises the following steps: generating a generation A by using the populus bolleana as the stock and the populus simonii as the scion; generating a generation B by using white poplar as the stock and the populus marilandica as the scion; generating a generation C by using the populus wilsonii as the stock and the populus marilandica as the scion; generating a generation D by using the white poplar as the stock and the populus simonii as the scion; further generating a generation X by using the generation A as the stock and the generation B as the scion, and generating a generation Y by using the generation C as the stock and the generation D as the scion; and generating a generation W by using the generation X as the stock and the generation Y as the scion, thus obtaining the poplar seeds with color-variable leaves. The poplar seeds cultivated by the invention have the advantages of rapid growth, resistance to longicorn and other plant diseases and insect pests, high freezing resistance, wide applicable range and flying-butt prevention in spring.

Description

The plant cultivation method of color-variable leaves

Technical field:

The invention belongs to the plant cultivation method of the breeding method of plant, particularly a kind of color-variable leaves.

Background technology:

The blade of general willow has only a kind of color, transfers to dark greenly with changes of seasons by light green, begins flavescence, turns white withered at last coming off to autumn.

Summary of the invention:

The plant cultivation method that the purpose of this invention is to provide a kind of color-variable leaves.

Purpose of the present invention realizes according to following proposal:

A kind of plant cultivation method of color-variable leaves, adopt the Xinjiang poplar, populus simonii, the living poplar of U.S. lotus speed, Chinese white poplar is basic seeds, through too much generation, polynary grafting and breeding forms, make stock with the Xinjiang poplar, populus simonii does scion and produces A generation, and white poplar makes stock, the living poplar of U.S. lotus speed does scion and produces B generation, Chinese white poplar makes stock, and the living poplar of U.S. lotus speed does scion and produces C generation, and white poplar makes stock, populus simonii does scion and produces D generation, make stock with A generation again, in B generation, done scion and produces X generation, makes stock with C generation, D produces Y generation for doing scion, make stock with X generation again, in Y generation, done scion and produces W generation, promptly obtains the seeds of color-variable leaves.

The present invention is at the young leaves initial stage, and leaf is aubergine, is blackish green mid-term, and be crocus latter stage, and trunk was kermesinus in 1 year, becomes dirty-green in 1 year.

The present invention has following characteristics:

1, the growth of the seeds cultivated is fast, and 1 year spring, the segment of intercepting 12-15cm, bud be upwards directly in the insertion soil, just can grow the about 3 meters high little trees of a strain to the November, and diameter can reach 2cm.

2, damage by disease and insect such as anti-longicorn.

3, frost resistance is strong, can tolerate-24 ℃ low temperature.

4, wide accommodation.

5, the seeds cultivated of the present invention do not have willow catkins flying in the air spring, belong to the view seeds.

Embodiment:

Adopting Xinjiang poplar, populus simonii, the living poplar of U.S. lotus speed, Chinese white poplar is basic seeds, form through multi-generation grafting, poplar makes stock in Xinjiang, populus simonii does scion and produces A generation, white poplar makes stock, and the living poplar of U.S. lotus speed does scion and produces B generation, and Chinese white poplar makes stock, the living poplar of U.S. lotus speed does scion and produces C generation, white poplar makes stock, and populus simonii does scion and produces D generation, makes stock with A generation again, B produces X generation for doing scion, make stock with C generation, in D generation, done scion and produces Y generation, makes stock with X generation again, Y produces W generation for doing scion, promptly obtains the plant of color-variable leaves.

The method of plant propagation with cutting is adopted in grafting: remove growing point on the stock with blade earlier, simultaneously with blade by the intercotyledonary growing point of stock place insert downwards 1-1.2 centimetre dark, insert bamboo let, scion is whittled into about 0.5 centimetre wedge shape by 1cm place under the cotyledon with blade, when extracting bamboo let, scion is inserted, accompany and attend to meticulously after the wrapping.

Grafting is preferably in the greenhouse to be carried out, and high temperature season will shade, avoid the high light direct projection with sunshade net or straw screen or mat, and temperature suitable during grafting should be 24-28 ℃, and relative air humidity is more than 75%.

Claims

1. the plant cultivation method of a color-variable leaves, adopt the Xinjiang poplar, populus simonii, the living poplar of U.S. lotus speed, Chinese white poplar is basic seeds, through too much generation, polynary grafting and breeding forms, the Xinjiang poplar makes stock, and populus simonii does scion and produces A generation, and white poplar makes stock, the living poplar of U.S. lotus speed does scion and produces B generation, Chinese white poplar makes stock, and the living poplar of U.S. lotus speed does scion and produces C generation, and white poplar makes stock, populus simonii does scion and produces D generation, make stock with A generation again, in B generation, done scion and produces X generation, makes stock with C generation, D produces Y generation for doing scion, make stock with X generation again, in Y generation, done scion and produces W generation, promptly obtains the seeds of color-variable leaves.
