Description

A kind of Chinese tallow tree seeds Stratification technique

Technical field

The present invention relates to Chinese tallow tree seeds vernalization field more particularly to a kind of Chinese tallow tree seeds Stratification techniques.

Background technology

Chinese tallow tree is Euphorbiaceae sapium deciduous tree, a kind of Colour-leaved trees.Spring and autumn leaf color is red gorgeous brilliant, not lower red maple, Chinese tallow tree is the distinctive economic tree of China, has more than 1400 years cultivation history.

Chinese tallow tree is stronger to the adaptability of soil, in great soil groups such as red soil, yellow earth, yellowish-brown soil, purple soil, brown earth, from sand to The soil of viscous differing texture, and acid, neutral or subalkaline soil, can grow, be the strong arbor species of salt-resistance it One.Chinese tallow tree requires have higher soil moisture, and is resistant to short-term ponding.With having certain wind resistance and pleat swallow more resistance to dry morning simultaneously It is barren.In addition, Chinese tallow tree has stronger resistance to toxic hydrogen fluoride gas.Chinese tallow tree is used as medicine with root skin, bark, leaf.Root skin and bark The four seasons can adopt, and slice dries；The more using fresh herbs of leaf, desinsection, removing toxic substances, diuresis, defaecation.For snail fever, cirrhotic ascites, stool and urine It is unfavorable, venomous snake bite；Furunculosis, corn, mastitis, traumatic injury, eczema, dermatitis are controlled in external application.

It is especially distributed more widely in Wannan mountainous area in China on the south south China, East China, the Qinling Mountains and Huaihe River.Especially It has been in the gesture that supply falls short of demand as the dryness pitch that its benevolence is squeezed is high all the way in recent years to be.Its wood producing speed simultaneously Comparatively fast, it is the good raw material of wood-based plate.

However Chinese tallow tree percentage of seedgermination is low at present, low so as to cause nursery planting percent, production capacity cannot be satisfied the market demand.

Invention content

Present invention aim to address the problem of.

The technical solution adopted by the present invention is：A kind of Chinese tallow tree seeds Stratification technique, includes the following steps：Step 1: will tree Kind, which is placed in 60 °C of water, impregnates 6~8h, is then exposed to the sun 3 days；Step 2: at a temperature of 10~15 °C, seeds are placed in logical 4~6 days at wind, and a water mist is sprayed every 1~2h；Step 3: seeds are positioned in wooden case 20~40 days, and in wooden case In be put into the river sand for being twice in seed volume, carry out stratification, ensure that wooden the temperature inside the box at 15 °C or so, is often stirred and examined It looks into；And spray cold water on wooden case surface；Step 4: wooden case is transferred in 20~25 °C or so of raising chamber, seen every 6 hours It examines primary；After 40% or so seeds breaches occur and leaking out kind of clothing, can both it sow；Step 5: when step 4 kind seeds only go out Existing small area breach in the environment of wooden case is then transferred to 10 °C or so, improves the resistance of semina there is no kind of a clothing is leaked out.

As a further improvement on the present invention, in step 1, first 6h is impregnated with 0.5% liquor potassic permanganate.

The advantageous effect that the present invention uses is：The Chinese tallow tree seeds Stratification technique of the present invention using the control in temperature and is aided with Humidity regulation appropriate, to the development of limited control seeds plumule so that the bud ratio of seeds is substantially increased, and is had good Activity, improve the lumber recovery of seedling.

Specific implementation mode

With reference to embodiment, the present invention is described further.

A kind of embodiment 1, Chinese tallow tree seeds Stratification technique, includes the following steps：

Step 1: seeds are placed in 6~8h of immersion in 60 °C of water, then it is exposed to the sun 3 days；

Step 2: at a temperature of 10 °C, seeds are placed in ventilation 4 days, and a water mist is sprayed every 1h；

Step 3: seeds are positioned in wooden case 20 days, and it is put into the river sand for being twice in seed volume in wooden case, carries out lamination Vernalization ensures that wooden the temperature inside the box at 15 °C or so, is often stirred and checked；And spray cold water on wooden case surface；

Step 4: wooden case is transferred in 20 °C or so of raising chamber, it is primary every observation in 6 hours；When 40% or so seeds of appearance Breach and after leaking out kind of clothing, can both sow；

Step 5: when small area breach only occur in step 4 kind seeds, there is no kind of a clothing is leaked out, then wooden case is transferred to 10 °C of left sides Under right environment, the resistance of semina is improved.

Embodiment 2, a kind of Chinese tallow tree seeds Stratification technique, it is characterized in that including the following steps：

Step 1: first impregnating 6h with 0.5% liquor potassic permanganate, then seeds are placed in 6~8h of immersion in 60 °C of water, then It is exposed to the sun 3 days；Chinese tallow tree seeds are carried out to disinfect and handle seeds surface kind shell early period.

Step 2: at a temperature of 15 °C, seeds are placed in ventilation 6 days, and a water mist is sprayed every 2h；So that tree The abundant imbibition of kind, softens kind of a skin, intraseminal substance is allow to be transformed into the substance that plumule absorbs.

Step 3: seeds are positioned in wooden case 40 days, and it is put into the river sand for being twice in seed volume in wooden case, carries out Stratification ensures that wooden the temperature inside the box at 15 °C or so, is often stirred and checked；And spray cold water on wooden case surface；Tree in case Kind quantity is about placed into the 2/3 of case height, in order to stir and check；The ratio of seeds and river sand is about 1 in case:2.At this time Seeds cell has stable water content so that plumule accumulates more nutrients.

Step 4: wooden case is transferred in 25 °C or so of raising chamber, it is primary every observation in 6 hours；When appearance 40% or so Seeds breach and after leaking out kind of clothing, can both sow；

The Chinese tallow tree seeds Stratification technique of the present invention using the control in temperature and is aided with humidity regulation appropriate, to limited Control the development of seeds plumule so that the bud ratio of seeds is substantially increased, and has good activity, improves becoming a useful person for seedling Rate.

Those skilled in the art, can also be it is to be understood that the protection scheme of the present invention is not limited only to the above embodiments Various permutation and combination and transformation are carried out on the basis of above-described embodiment, under the premise of without prejudice to spirit of that invention, to the present invention The various transformation carried out are all fallen in protection scope of the present invention.
