The treatment method concretely comprises the following steps: (1) harvesting seeds; (2) screening the seeds and carrying out air drying of the seeds; (2) carrying out high temperature treatment; and (4) germinating seeds. The operation is simple and easy to carry out, the management cost is low, the technical requirement is simple, and the method is easy to promote and apply. The method can be widely applied to the Salix myrtillacea seed seedling and slope ecological restoration and control engineering technology.
Description
technical field:
The present invention relates to a kind of processing method improving aalii seed germination rate, belong to plant seed seedling growing process field.
background technology:
Aalii (
dndonaeaviscosal.) akeake, bright foxy old hand is had another name called, genus Sapindaceae (Sapindaceae) akeake belongs to (
dodonaeamiller) perennial evergreen shrub or dungarunga, be often born in arid hillside, spacious, be distributed in global subtropical and tropical zones, China is mainly distributed in the west and south, south to the southeast, often forms multiple typical association view at dry-hot valley.Its root system is very flourishing, has stronger drought-resistant, impoverishment tolerant ability, and has the strong characteristic of sprouting ability, the revegetation species that Chang Zuowei arid and semi-arid lands is important.But aalii is introduced a fine variety to Central Yunnan find, after its seed maturity, germination rate is extremely low at normal temperatures, be only about 7.00%, directly have influence on aalii and be used in effect in ecological recovery and efficiency, need the germination rate how solution improves aalii seed at present badly, save germ plasm resource, make it be applied to effect in the ecological recovery of Central Yunnan and efficiency is increased dramatically.
summary of the invention:
For the problems referred to above, the technical problem to be solved in the present invention is to provide a kind of processing method improving aalii seed germination rate.
A kind of processing method improving aalii seed germination rate of the present invention, its concrete steps are:
1, seed collection: at annual late September to late November aalii seed maturity, directly cut seed-bearing fruit branch with secateurs, gathers in the lump and takes back indoor; Remove pericarp, sprig and other impurity after gathering in time, retain the seed that kernel seed coat colour is black;
2, seed screening and air-dry: the running water by the kernel seed coat colour of gathering being aalii seed 3 times of volumes of black screens, the seed of the floating water surface of reject after 10 minutes, the remaining seed sinking to container bottom is the seed of mature and plump, select and air-dry rear for subsequent use by 48 hours under being positioned over normal temperature laboratory, there is the seed of small holes caused by worms air-dry period with artificial removal;
3, high temperature treatment: the temperature inside the box 80 DEG C is set with thermostatic drying chamber, white disk or other resistant to elevated temperatures pallet are put into case simultaneously, when the temperature inside the box rises to 80 DEG C, above-mentioned seed for subsequent use is put into pallet and process 5 ~ 20min under the constant temperature of 80 DEG C, constantly to stir seed during process, its every seed is heated evenly; Process terminates rear taking-up and is positioned over indoor, then stirs 3 ~ 5 times, for subsequent use after being down to room temperature;
4, seed germination: seed high temperature treatment crossed is placed on fine sand or filter paper to be sprouted, and temperature controls in (25 ± 2) DEG C, and germination rate reaches more than 60%.
Beneficial effect of the present invention is: it is easy to operation, and management cost is low, and technical requirement is simple, easily applies, can be widely used in aalii seed seedling-raising and slope ecological recovery harnessing project technology.
embodiment:
For making the object, technical solutions and advantages of the present invention clearly understand, below by the specific embodiment illustrated to describe the present invention.But should be appreciated that, these describe just exemplary, and do not really want to limit the scope of the invention.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present invention.
This embodiment is by the following technical solutions: its concrete steps are:
1, seed collection: at annual late September to late November aalii seed maturity, directly cut seed-bearing fruit branch with secateurs, gathers in the lump and takes back indoor; Remove pericarp, sprig and other impurity after gathering in time, retain the seed that kernel seed coat colour is black;
2, seed screening and air-dry: the running water by the kernel seed coat colour of gathering being aalii seed 3 times of volumes of black screens, the seed of the floating water surface of reject after 10 minutes, the remaining seed sinking to container bottom is the seed of mature and plump, select and air-dry rear for subsequent use by 48 hours under being positioned over normal temperature laboratory, there is the seed of small holes caused by worms air-dry period with artificial removal;
3, high temperature treatment: the temperature inside the box 80 DEG C is set with thermostatic drying chamber, white disk or other resistant to elevated temperatures pallet are put into case simultaneously, when the temperature inside the box rises to 80 DEG C, above-mentioned seed for subsequent use is put into pallet and process 5 ~ 20min under the constant temperature of 80 DEG C, constantly to stir seed during process, its every seed is heated evenly; Process terminates rear taking-up and is positioned over indoor, then stirs 3 ~ 5 times, for subsequent use after being down to room temperature;
4, seed germination: seed high temperature treatment crossed is placed on fine sand or filter paper to be sprouted, and temperature controls in (25 ± 2) DEG C, and germination rate reaches more than 60%.
In this embodiment, seed germination rate improves 8 ~ 9 times than before process, and germination rate reaches more than 60%, reaches as high as 74%.Have easy to operation, facility requirements is few, and technical requirement is simple, the advantage easily applied, in the Ecological Restoration Works of aalii seeling industry and Central Yunnan, have important application and promotional value.
