Description

A kind of Water culture propagation method for oil tea vegetative propagation

Technical field

The present invention relates to a kind of propagation methods of oil tea, more particularly to a kind of Water culture for oil tea vegetative propagation Propagation method.

Background technique

Oil tea is most productive oily species in Theaceae Camellia, and sensu lato oil tea refers to that Camellia is planted Seed oil content is higher in object, and has certain general designation cultivated and manage the tree species of area.Oil tea originates in and main cultivation is in China, with oil Olive, oil palm, coconut and the referred to as big traditional oil tree in the world four, existing about 4,000,000 mu of camellia oleifera lam area of the whole nation account for China's wood 80% or more of this edible oil materials tree species cultivated area.The major product of oil tea is tea oil, is pushed away by FAO's emphasis Wide health type edible oil, unsaturated fatty acid content are up to 90% or more, are known as " east olive oil ".In recent years, due to Country widelys popularize oil tea plantation, and the demand of nursery stock resource shows in short supply especially.

Mainly there are Nurse seed grafting method, autumn branches method and three kinds of cuttage in the asexual reproduction method of oil tea, wherein skewer The utilization rate of fringe bar can be improved, and do not limited by stock using unavailable shady branch and thin and delicate branch in propagation by grafiting by inserting breeding, Can cuttage at any time, be easy to operate, less investment in asexual multiplication seedling, quick method.Traditional oil tea cuttage Chang Yin It is carried out in canopy, moisturizing is carried out by covering film, matrix is often yellow soil, and Cutting conditions and environment are not easy to control, to cause Survival rate it is unstable.

Summary of the invention

The object of the present invention is to provide a kind of Water culture propagation methods for oil tea vegetative propagation, on effectively overcoming State the deficiencies in the prior art.

The scheme that the present invention solves technical problem is: a kind of Water culture propagation method for oil tea vegetative propagation, packet Process is managed after including the preparation in cuttage place, the preparation of cuttage vessel, cuttings processing, cuttage and cuttage, acquisition tree crown periphery is thick It is strong logical straight, axillary bud is full, the oil tea autumn growth that blade completely gives birth to semi-lignified or lignifying for the year is trimmed to after cuttings to be inserted into and insert Fringe fixed plate is placed in the ready cuttage vessel equipped with nutrient solution, conserve by managing after cuttage up to taking root, It includes operating procedure in detail below:

1) preparation in cuttage place: selecting heliogreenhouse as cuttage place, builds 3~5 layers of culturing rack with angle steel, and be equipped with and carry Plate；

2) it the preparation of cuttage vessel: selects opaque rectangular plastic hopper as cuttage vessel, nutrition is poured into cuttage vessel Liquid, Depth Nutrient Solution are 4~6cm；And it is cut into cuttage vessel size with black flexible plastic hole tray, and beaten at cavities with punch Diameter is the aperture of 0.3cm, as cuttings fixed plate；

3) cuttings is handled: acquisition tree crown periphery it is sturdy it is logical straight, axillary bud is full, blade completely gives birth to semi-lignified or lignifying for the year Oil tea autumn growth, be trimmed to the branch of the double buds of double leaf of 6~8cm as cuttings；

4) it cuttage: by the aperture of the cuttings handled well insertion cuttings fixed plate, is then placed in cuttage vessel, is placed in training It supports on frame；

5) manage after cuttage: the room temperature control in cuttage place is 20~30 DEG C, and indoor humidity control is 90~100%；It is pumped with oxygen Timing is ventilated in the nutrient solution into cuttage vessel, until taking root.

In step 1), the size of the heliogreenhouse is 3~8 square metres；The culturing rack is wide by 60~ 80cm, for length depending on indoor conditions, 60~70cm of interlamellar spacing uses glass as support plate.

In step 2, the wide 20~30cm of the cuttage vessel, long 50~60cm, deep 6~8cm；The soft modeling of black The density of material cave disk be 400 caves/square metre, cave depth 1cm.

In step 2, its material content of the nutrient solution are as follows: 2g containing indole -3-butyric acid, calcium nitrate in every liter of solution 940~1200mg, 600~650mg of potassium nitrate, 100~130mg of phosphoric acid dihydro amine, 480~500mg of epsom salt and second two Amine tetraacethyl ferrisodium 18~25mg of salt, is added citric acid solution and sodium hydroxide solution adjusts liquid PH value to 4.5~6.5.

In step 5), the room temperature covers shading net on cuttage place by the ventilation opening in opening and closing cuttage place It is controlled；The indoor humidity is controlled by humidifier.

In step 5), the frequency that the timing is ventilated in the nutrient solution into cuttage vessel is every ventilation 1 in 1 hour Hour.

Compared with the existing technology, the invention has the advantages that: the present invention prepares excellent nutrient solution, has adjusted benefit In the pH value that oil tea takes root, it is raw to improve cuttage for influence by nutrient, plant growth regulator etc. to oil tea cuttage root-taking Root rate, 100 days rooting rates of cuttage reach 95% or more；Meanwhile the conditions such as temperature, humidity, ventilation are complete during cutting propagation Controllably, nutritional ingredient absorbability is strong, well developed root system, and cutting plantation is high and stablizes, and has preferable economic benefit, society's effect Benefit and ecological benefits；Culturing rack of the invention can be ground as support plate by glass convenient for observation rooting process for oil tea rooting mechanism Offer convenience is provided.

Specific embodiment

Below with reference to embodiment, the present invention is described in further detail.

Embodiment

Water culture propagation method of the invention, the preparation of preparation, cuttage vessel including cuttage place, cuttings processing, Manage process after cuttage and cuttage, acquisition tree crown periphery it is sturdy it is logical it is straight, axillary bud is full, blade completely give birth to for the year semi-lignified or The oil tea autumn growth of lignifying is inserted into cuttings fixed plate after being trimmed to cuttings, is placed on the ready cuttage vessel equipped with nutrient solution In, conserve until taking root by managing after cuttage, it includes operating procedure in detail below:

1) preparation in cuttage place: selecting heliogreenhouse as cuttage place, builds 4 layers of culturing rack with angle steel, and be equipped with support plate；

2) it the preparation of cuttage vessel: selects opaque rectangular plastic hopper as cuttage vessel, nutrition is poured into cuttage vessel Liquid, Depth Nutrient Solution 5cm；And it is cut into cuttage vessel size with black flexible plastic hole tray, and beaten directly at cavities with punch Diameter is the aperture of 0.3cm, as cuttings fixed plate；

3) cuttings is handled: acquisition tree crown periphery it is sturdy it is logical straight, axillary bud is full, blade completely gives birth to the oil tea autumn of lignifying for the year The tip is trimmed to the branch of the double buds of double leaf of 7cm as cuttings；

5) manage after cuttage: the room temperature control in cuttage place is 25 DEG C, and indoor humidity control is 95%；With oxygen pump periodically to skewer It inserts and ventilates in the nutrient solution in container, until taking root.

In step 1), the size of the heliogreenhouse is 6 square metres；The wide 70cm of the culturing rack, length Depending on indoor conditions, interlamellar spacing 65cm uses glass as support plate.
