Abstract

The invention discloses a seed selection method for forestry. The method comprises the steps of collecting, namely cutting off fruit branches with ripen seeds in the same year, collecting the branches and tedding the branches under the sun until drying on a drying yard and repeatedly beating the branches to collect falling seeds; cleaning, namely putting the collected seeds into a container, soaking the seeds into water, fully stirring and then standing; air drying, namely fishing out the full seeds at the bottom of the container, draining the water and tedding the seeds until air drying; dust removal, namely removing dust in the dried seeds by using gentle breeze of an electric fan; storing, namely bagging the clean full seeds and storing the seeds in a freezer of -20 DEG C for later use. The method is simple, convenient, fast and effective, and has the advantage of halving the work with double results; a lot of full seeds can be selected as the materials for germination experiments and sowing within a very short period of time; and the seed selection method is very beneficial to popularization and application in production and plays a positive role in propagation of a desert plant redwood.

Description

A kind of method of forestry seed seed selection

Technical field

The present invention relates to plant propagation and technical field of seed breeding, specially a kind of method of forestry seed seed selection.

Background technology

Red sand（Reaumurta soongorica）Another name Folium Eriobotryae bavin, the super non-irrigated raw undershrub of category Ramulus et Folium Tamariciss section red sand category fallen leaves, The category Cretaceous period, Paleogene period Relict Plant, are the main advantages in temperate district area of China, steppificated desert and desert steppe area One of kind and constructive species, are also to be grown in this area's distribution most one of maximum zonal vegetation of wide, ecological ampliture, extensively It is distributed in Xinjiang of China, Qinghai, Gansu, Ningxia, the Inner Mongol and the Northeast.Thick protein and crude fat content when red sand is dark green It is higher, it is the medium feeding shrubbery of quality, camel four seasons eating, sheep, horse search for food in good time.Additionally, red sand twig, leaf can be used to control Treat eczema, dermatitis, solution thermal sweating etc..Red sand also has very strong drought resisting, salt tolerant, fixes the sand, resists various good characteristics such as barren, is The main pionner of China's temperate district, is also a kind of water and soil conservation having a high potential and green barren hill seeds, is that protection is dry The important ecology " barrier " of non-irrigated Desertification Soil, for the ecological protection and checking winds and fixing drifting sand of Desert Regions ecological is anticipated with important Justice, plays an important role in terms of the stability and sustainability that maintain desert ecosystem.

In recent years, due to the long term by nature and mankind's activity, serious degradation and the desertification of red sand meadow is compeled to be essential Recover and rebuild.The recovery and reconstruction of plant population had both depended on the growth of individual in population size, again relied on number of individuals The increase of amount, and the latter has more profound meaning in extremely arid environment.Although wild red sand bears seeds a lot, in the wild During natural propagation, the seedling numbers for surviving are little.Meanwhile, as climate change, soil are seriously desertified, excessively put Herd, wild resource almost exhausts.So, urgent need seeks a kind of tame propagation method.And the work is engaged in, first Need collecting fruit, clean seed, in case production needs.Red sand is typically in 6 July at the end of month flower opened just now, and the first tenday period of a month in August are solid, and 9 Seed maturity at the beginning of the end of month to 10 months, because the seed of red sand is about 3gram, little drops, Long Circle, comprehensively by hair, using biography System technology and method are difficult to collect pure fruit and seed, and to research and production certain difficulty is brought.Accordingly, it would be desirable to solve The technology and method of certainly wild red sand seed collection/clean.At present, the country there is no the wild red sand seed collection of development and clean skill The patent or research report of art and method.

The content of the invention

It is an object of the invention to provide a kind of method of forestry seed seed selection, can clean out within a very short time large quantities of full Expire seed as the material for sprouting experiment and sowing, beneficial to popularization and application in production.

For achieving the above object, the present invention is employed the following technical solutions：

A kind of method of forestry seed seed selection, comprises the following steps：

1）Collection

The branch of result then with mature seed is cut, is collected and is taken back preprepared threshing ground and ted in sunlight Under, shine to air-drying, heap is then beaten, gently beaten repeatedly with resilient withe bar, collect the seed for coming off；

2）Cleaning

During the seed collected is placed in into basin or barrel, is soaked with enough water and stood after being sufficiently stirred for；

3）Air-dry

Container middle and upper part floater and floating impurity are removed, the full seed of container bottom is pulled out and is drained away the water and is spread out Shine to air-dry；

4）Dedusting

The mild wind shone to air-dried full seed electric fan is removed into dust；

5）Seal up for safekeeping

By the pack of clean full seed, and it is positioned over -20 DEG C of refrigerator-freezers and seals up for safekeeping with standby,.

As further scheme of the invention, the step 2）The temperature of water is 18 DEG C -20 DEG C.

As further scheme of the invention, the step 2）The time of stirring is 5-10 minutes.

Compared with prior art, advantages of the present invention：The method is simple and convenient, quick effective, excellent with what is got twice the result with half the effort Point；Large quantities of full seeds can within a very short time be cleaned out as the material for sprouting experiment and sowing, production is very beneficial to Positive role is played in middle popularization and application, the breeding to desertification plant red sand.

Specific embodiment

With reference to specific embodiment, the present invention is further elaborated.

1）Collection

2）Cleaning

During the seed collected is placed in into basin or barrel, 5-10 point is soaked and is sufficiently stirred for enough 18 DEG C -20 DEG C of water Stand after clock；After standing, now full seed sinks to container bottom, and impurity and floater swim in top；

3）Air-dry

4）Dedusting

The mild wind shone to air-dried full seed electric fan is removed into dust；

5）Seal up for safekeeping

Experiment repeatedly through for many years obtains drawing a conclusion：Fresh red sand seed is sprouted after the process of the present invention Rate can reach more than 95%；After red sand seed after -4 DEG C～4 DEG C cryopreservation is placed 2 years, after the present invention is processed, sprout The rate of sending out can still reach more than 70%；If preserving under -20 DEG C of cryogenic conditions, the red sand seeds time can be longer；And red sand kind Son is in In China West Arid Land room temperature（20～25 DEG C）Storage 1 year, germination rate only has 60%, preserves 2 years, and highest germination rate only has 50%, Cryopreservation can extend seed vitality, keep higher germination rate.Therefore, by the air-dried full seed dress for washing out Bag, be positioned over -20 DEG C of refrigerator-freezers seal up for safekeeping with it is standby be preferred plan.The method can within a very short time clean out large quantities of full kinds Son is very beneficial to popularization and application in production as the material for sprouting experiment and sowing, and the breeding to desertification plant red sand rises To positive role.

Embodiments described above is only a part of embodiment of the invention, rather than the embodiment of whole.Based on this Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made Example is applied, the scope of protection of the invention is belonged to.
