Abstract

A woody plant cuttage method comprises the following steps: girdling the skin, 10-100 mm above a pre-cutting port, of cuttings for a circle in advance; completely removing the skin, below the girdling skin, of the cuttings during cuttage to expose the woody parts; disinfecting with a disinfection solution; handling with a rooting agent; finally, inserting the cuttings into a wet seedbed matrix, and properly shading till rooting. According to the woody plant cuttage method, in-advance girdling of the cuttings can prevent infection and increase nutrient substance accumulation of branches; as the woody parts are exposed outside, the moisture absorption capability is improved, the cuttings are protected from water loss and dry rot before rooting, and accordingly, the survival rate is improved.

Description

A kind of woody plant cottage method

Technical field

The present invention relates to the vegetative technical field of woody plant seedling, particularly a kind of woody plant cottage method.

Background technology

Cuttage is one of the most frequently used method of plant propagation.It has the features such as reproduction speed gathers soon, easily, inheritance change is little, convenient management.The nutriment of the branch of cuttage is abundanter, and cuttage easily survives, and grows also better.Because the content of stored nutrient material and component, closely related with difficulty or ease of taking root in branch.Usual branch carbohydrate is more, takes root easier, all needs to consume organic nutrition because take root and germinate.

But the contained nutriment of cutting itself is very limited, if cutting can not grow enough roots and leaf manufactures nutrient to carry out photosynthesis before its nutriment runs out of, cutting just can not survive.And be with leaf cuttage can not only carry out photosynthesis, required carbohydrate of taking root is provided, and can synthesize Endogenous auxin stimulate take root, the leaf area of cutting is greatly then conducive to taking root.But because cutting WUGENYE area is larger, transpiration rate is larger, because new root not yet generates, moisture cannot be supplied smoothly, and the continuous dehydration because of transpiration of the branch section of cutting and blade, cutting is easily withered.Nutriment contained by visible cutting is few and dehydration is dried up before taking root is the main cause of cuttage failure.

Summary of the invention

For solving the problem, the object of the invention is to provide a kind of and preventing the cutting woody plant cottage method that dehydration is withered before taking root.

The technical solution used in the present invention realizes mainly through following steps:

Step one: 1-20 days in advance, chooses lignified branch more than 10-100mm above pre-clip and locates, enclose with blade ring cutting epidermis one.

Step 2: all remove to epidermis during cuttage, the ring cutting epidermis of cutting being sentenced lower part and spill xylem, and remove the too much leaf of branch, every root cutting only retains 1-20 sheet leaf.

Step 3: cutting was sterilized with antiseptic solution before cuttage,

Step 4: then auxin process is carried out to cutting.

Step 5: the cutting cuttage handled well is irrigated to by medium of seedling bed with water, and suitably can shade according to the resistance to cloudy degree of plant, keep medium of seedling bed moistening, increase the intensity of scattered light after taking root gradually until under being exposed to natural sunlight completely.

As can be seen from the technical solution used in the present invention, shift to an earlier date ring cutting to cutting to be convenient to otch and to do sth. in advance healing and protect from infection, increase shoot vegetative substance accumulation, xylem cutting bottom being spilt 10-100mm considerably increases cutting and absorbs the ability of moisture and avoid dehydration before rooting of cuttings and dry up, thus several leaves can be stayed to carry out photosynthesis and then improve survival rate more.

Embodiment

The present invention will be further described to lift object lesson below

Step one: the branch that cutting is selected then or last year is raw sturdy, about 2-7 days are shifted to an earlier date as cutting, choose lignified branch more than 10-100mm above pre-clip to locate, enclose with blade ring cutting epidermis one, in advance ring cutting is convenient to otch and is done sth. in advance healing and protect from infection, due to branches and leaves by the nutriment that photosynthesis produces be by epidermis toward root conveying block nutriment carry toward bottom, after ring cutting, nutriment is piled up in incision, increase shoot vegetative substance accumulation and.

After step 2: 2-7 days, cutting is cut from 40mm place under ring cutting epidermis, and epidermis ring cutting being sentenced lower part all removes and spills 40mm xylem, and be whittled into inclined-plane to increase water absorbing capacity, epidermis is many hinders branch to absorb moisture containing wax, the xylem of removing epidermis can touch moistening medium of seedling bed fully, and absorb moisture for branch consumption by wooden capillarity, and remove the too much leaf of branch, every root cutting only retains 1-20 sheet leaf.

Step 3: the cutting machine mercurial of 1000 times of liquid, carbendazim, benomyl, topsin, tpn or formalin solution were soaked for 15-30 seconds,

Step 4: before cuttage by below under ring cutting epidermis place, cutting lower end with methyl α-naphthyl acetate, ABT root-inducing powder or indolebutyric acid process 3-5 second, the concentration of root-growing agent controls at 0.2%--1%, effectively can improve cutting plantation, shorten rootage duration and increase root of hair quantity.

Claims

1. a woody plant cottage method, is characterized in that:

Step one: 1-20 days in advance, chooses lignified branch more than 10-100mm above pre-clip and locates, enclose with blade ring cutting epidermis one,

Step 2: to cutting to be cut from pre-clip during cuttage and the epidermis ring cutting epidermis of branch being sentenced lower part all removes and spills xylem, every root cutting only retains 1-20 sheet leaf,

Step 3: cutting was sterilized with antiseptic solution before cuttage,

Step 4: then auxin process is carried out to cutting,

2. a kind of woody plant cottage method as claimed in claim 1, is characterized in that: be whittled into inclined-plane below the xylem of described cutting bottom removing epidermis.

3. a kind of woody plant cottage method as claimed in claim 1, is characterized in that: described is 15-30 seconds of machine mercurial, carbendazim, benomyl, topsin, tpn or formalin solution immersion with 1000 times of liquid with antiseptic solution sterilization.

4. a kind of woody plant cottage method as claimed in claim 1, is characterized in that: described HORMONE TREATMENT is for methyl α-naphthyl acetate, ABT root-inducing powder or indolebutyric acid process 3-5 second, and the concentration of root-growing agent controls at 0.2%--1%.
