Abstract

The invention discloses a method for screening red-leaf variant plants from acer truncatum seedlings and relates to the field of botanical horticulture. According to the method, mature acer truncatum fruits harvested in the autumn are selected, germinated seedlings are subjected to low-temperature and short-day treatment under the environmental conditions of different illumination intensity and time on the basis of a traditional sowing and seedling raising method, leaves of the acer truncatum seedlings are enabled to turn red, the red-leaf acer truncatum is rapidly propagated and cultivated into a new variety, the cultivation period is 3-4 months, the efficiency of breeding work of the red-leaf acer truncatum is greatly improved, a large number of the variant plants of the red-leaf acer truncatum are obtained, the quality of the variant plants of the red-leaf acer truncatum is good, autumn colored-leaf tree species are enriched for people's selection, landscape construction is facilitated, and the overall cultivation process is completed by instruments such as a refrigerated container, an illumination incubator and the like, so that expense cost of land and field management and the like is greatly reduced; the cultivation method is simple, easy to operate and suitable for large-range popularization and application, and the red-leaf acer truncatum plays a role in preserving the ecological environment better.

Description

A kind of method that red autumnal leaves variation individual plant is screened in the seedling from acer truncatum

Technical field

The present invention relates to botanical horticulture field, specifically one kind screens red autumnal leaves variation individual plant from acer truncatum seedling Method.

Background technology

The acer truncatum leaf color that autumn leaves reddens is beautiful, and appreciation effect is splendid.The selection of traditional red autumnal leaves acer truncatum mostly be by After the mixed wet sand seed soaking of acer truncatum fruit that autumn harvesting comes, it is new that seed propagation obtains part red autumnal leaves acer truncatum after growing up to seedling Kind, the cycle is more long.In the last few years, with socio-economic development, class flowers, the trees market demand are viewed and admired and is increased sharply, by economic profit Beneficial trend, various regions need largely to be viewed and admired the plant of class, it is desirable to shorten its breeding cycle, obtain a large amount of high-quality ornamental plants Kind.

The content of the invention

To solve above-mentioned technical problem, red autumnal leaves variation list is screened from acer truncatum seedling the invention provides one kind The method of strain, the screening cycle of red autumnal leaves acer truncatum variation individual plant is foreshortened to 3-4 month from traditional 1-2 to the several years, is improved The efficiency of red autumnal leaves acer truncatum seed selection work, the expense cost such as Economization on land and field management is conducive to Urban Landscape Construction.

To reach above-mentioned purpose, the technical solution adopted in the present invention is：

A kind of method that red autumnal leaves variation individual plant is screened in seedling from acer truncatum, is achieved by the steps of：

(1) autumn indoor seeding nursery：Acer truncatum fruit after autumn harvesting maturation, fruit and wet sand（30% water content）Press 1:1 ratio is sufficiently mixed, and is positioned over 4 DEG C of preservations in refrigerating box, after 40 days indoors（20 DEG C of room temperature）Seeding and seedling raising, illumination is strong It is 20000lx to spend, and periodicity of illumination is controlled to illumination 10-16h, and corresponding interlunation is 14-8h；

(2) low temperature short-day sunshine treatment：After coming up 30 days, nursery temperature is set to 12-18 DEG C of daytime, 8-14 DEG C of night, illumination Cycle is illumination 7-10h, dark 17-14h, is processed 16-22 days, and whether observation seedling has blade to start to turn red；

(3) selection of red autumnal leaves seedling：The seedling that blade turns red is selected during treatment at any time, after 20 days, seedling fallen leaves enter dormancy, Now the selected small transplantation of seedlings of rest period can be selected beginning rudiment seedling to field, after 60-75 days.

The present invention on the basis of traditional seeding growing seedlings method, is borrowed from the acer truncatum fruit after autumn harvesting maturation Different illumination intensity and the environmental condition of time, the seedling that will go out figure carry out low temperature short-day sunshine treatment, its seedling leaves is reddened, The quick Propogation and culture of red autumnal leaves acer truncatum into the purpose of new varieties is realized, cultivation period is 3-4 month, drastically increases red autumnal leaves unit The efficiency of precious maple seed selection work, the red autumnal leaves acer truncatum variation individual plant quantity of acquisition is big, quality better, enriches people to autumn leaves coloured silk leaf The selection of seeds, is conducive to Urban Landscape Construction, and the whole process cultivated is by instruments such as refrigerating box, illumination boxs come complete Into, the expense costs such as soil and field management are greatlyd save, breeding method is simple, easy to operate, is adapted to scope popularization and application, makes Obtain red acer truncatum and preferably play its effect preserved the ecological environment.
