CN105393668A - Method for relieving dormancy of cyclobalanopsis glaucoides schotky seeds - Google Patents

Abstract

The invention relates to a method for relieving the dormancy of cyclobalanopsis glaucoides schotky seeds and belongs to the technical field of plant seed seedling culture. The method adopts a dry-wet alternative technical means to relieve the dormancy of thecyclobalanopsis glaucoides schotky seeds, namely the seeds are repeatedly treated for three times by using an immersing-airing procedure; finally, the seeds are immersed in water at room temperature for 24 hours and are treated for 10 days so that seed coats are cracked and can easily absorb the water, and furthermore, the dormancy property of the cyclobalanopsis glaucoides schotky seeds, caused by mechanical inhibition of the seed coats, is relieved; and the germination rate of the seeds within 30-40 days is more than 95%. The method provided by the invention comprises the following steps: collecting and screening the seeds, immersing the seeds, airing and sowing the seeds. Compared with a treatment method of storing for 6 months, reported by the document, the method has the advantages of simplicity and convenience for operation, low cost and rapidness in germination. The method can be widely applied to seedling culture and afforestation of the cyclobalanopsis glaucoides schotky seeds.

Description

A kind of seed dormant method in releasing Qinggang, Yunnan

Technical field:

The invention belongs to plant seed seedling growing process field, be specifically related to a kind of releasing Qinggang, Yunnan (Cyclobalanopsisglaucoides) seed dormant method.

Background technology:

Qinggang, Yunnan is Fagaceae (Fagaceae) Cyclobalanopsis (Cyclobalanopsis) evergreen woodland arbor species, it is one of common indigenous tree species of Yunnan Center Yunnan Plateau semi-humid evergreen broad-leaved forest, be born in Limestone Mountain or Zhong Shan abrupt slope, there is resistance to felling, the characteristic that germinating power is strong, it is good In Limestone Area green barren hill, water and soil conservation, the seeds of the multi-functional woodss such as firewood charcoal material, but, because its seed has the characteristic of dormancy, dormancy time reaches more than 6 months, namely need Qinggang, Yunnan to be preserved more than 6 months its seeds could sprout, be not widely applied at present.

Releasing Yunnan provided by the invention Qinggang (Cyclobalanopsisglaucoides) seed dormant method, by literature search, has no the open report identical with the present invention.

Summary of the invention:

The object of the invention is to the deficiency overcoming prior art, and provide a kind of easy to operation, the seed dormant technical method in Qinggang, releasing Yunnan with low cost.

The present invention adopts the technological means of alternation of wetting and drying to remove Qinggang, Yunnan seed dormancy, namely the operation reprocessing 3 times of " dry in the shade-soak " is used, its seed coat is ftractureed and is beneficial to water suction and removes the hibernation feature of Qinggang, Yunnan seed due to the machinery suppression generation of its seed coat, in 30 ~ 40 days, germination rate reaches more than 95%.Concrete steps are as follows:

(1) seed collection and screening:

At annual Qinggang, Yunnan in 9 ~ October seed maturity, pick up receipts when directly manual after seed maturity drops ground or under tree, lay Polypropylence Sheet collection.50 DEG C of warm water of seed 2 times of volumes of gathering are screened and desinsection, the seed of the floating water surface of reject after 20 minutes, the remaining seed sinking to container bottom is the seed of mature and plump, select and for subsequent use after being dried in the shade by 48 hours under being positioned over normal temperature laboratory, there is the seed of small holes caused by worms period of drying in the shade with artificial removal.

(2) seed soaks and dries in the shade:

The water put into by the above-mentioned seed dried in the shade under room temperature soaks 24 hours, takes out subsequently and at room temperature naturally dries in the shade 48 hours; The water put into again under room temperature soaks 24 hours, takes out subsequently and at room temperature naturally dries in the shade 48 hours; Put into water immersion under room temperature again 24 hours, take out subsequently and at room temperature naturally dry in the shade 48 hours; Often criticize the operation reprocessing 3 times that seed adopts " soak-drying in the shade ", finally soak in water at room temperature again 24 hours for subsequent use, totally 10 days processing time.

(3) sow:

The seed of above-mentioned process is directly sowed on the seedbed having collective media matter thereon or in nutritious bag, thickness of earth covering 2 centimetres, waters 1 every day, and irrigation amount is not to occur that ponding is advisable, seed is through the sprouting of 30 ~ 40 days on culture matrix, and its germination rate reaches more than 95%.

The present invention, compared with the storage processing method of 6 months of bibliographical information, has advantage that is easy and simple to handle, with low cost, fast-germination.Can be widely used in Qinggang, Yunnan seed seedling-raising and afforestation.

Embodiment:
