Description

A kind of kiwi fruit green wood cutting method

Technical field

The present invention relates to fruit tree cuttage technique field, be specifically related to a kind of kiwi fruit green wood cutting method.

Background technology

Kiwi fruit is Actinidiaceae Actinidia, fallen leaves woody climber, rare evergreen, be distributed in East Asia, indivedual to Southeast Asia, the whole world has more than 54 kinds, Chinese style main producing region, has more than 52 kinds, from northeast to Hainan Island, all there is distribution from Tibet to Taiwan, mainly concentrate on the south the Qinling Mountains, area to the east of Hengduan mountain range.Kiwifruit fruit can be eaten raw, unique flavor, and Determination of Vitamin C is very abundant, and bristle Chinese gooseberry wherein has become the emerging fruit of hot topic in the world.Kiwi fruit leaf can raise pig; Branch leachate can be sized mixing agent for paper-making industry containing colloid, and it is used in combination to can be used for building aspect and cement, lime, yellow mud, sand etc., can play reinforcement effect, seals watt eaves ridge in order to surfacing, sunning ground and painting; Root can make insecticide pesticide; Flower is good nectar source; The branch of numerous species, leaf, flowers and fruits are all very attractive in appearance, and suitable planting in greening field does ornamental plants again.

The improved seeds that a collection of quality is superior, storage tolerance, resistance etc. differ from one another cultivated by kiwi fruit.But with seed propagation seedling, often there is larger variation.For keeping breeding characteristic, vegetative propagation must be adopted.Cuttage belongs to one of vegetative propagation technique, is the common method of breeding plant, is widely used in the fields such as veterinary antibiotics, flower gardening material, achievements in forest-tree seedling, traditional Chinese medicine in practice.The Main Function of cottage propagation has the hereditary capacity keeping seeds or kind, widens breeding channel, fast, high-quality, efficiently breeds nursery stock, regulates and utilize the phasic development rule etc. of trees.Of Propagation by Cuttage for Kiwifruit is a kind of asexual reproduction method directly utilizing the nutrition organs of plant to breed kiwi fruit seedling, is a kind of simple and easy to do, method of cultivating excellent nursery stock with getting twice the result with half the effort.

Summary of the invention

The object of this invention is to provide a kind of kiwi fruit green wood cutting method, solve the defect of kiwi fruit seed propagation seedling appearance compared with Big mutation rate.

For solving the problem, the present invention by the following technical solutions:

A kind of kiwi fruit green wood cutting method, comprises the steps:

Step one, from kiwi fruit, prime of life individual plant chooses raw spray then, cuttage bar 2 ~ 3 every section joints, and lower end is under joint, and upper end cuts flat at 2 ~ 3cm place on saving, and stays 1 ~ 2 blade;

Step 2, preparation cuttage seedbed, lower floor is the soil that 10 ~ 12cm is thick, and the thick clean river sand of upper strata paving 18cm ~ 20cm, carries out soil disinfection with pcnb, leveling furrow face;

In step 3, the cuttage seedbed that vertical for cuttage branch inserting step two prepared, part of burying is 2/3 ~ 3/4, and moisturizing of watering, wherein, seeding row spacing is 10 ~ 12cm × 10 ~ 12cm;

After step 4, cuttage, seedbed plastic film is barricaded as shed, and shed arranges sunshade net, keeps temperature 25 ~ 30 DEG C, air humidity 85 ~ 90%.

Cuttage branch is before cuttage, and the cuttage branch lower end methyl α-naphthyl acetate aqueous solution soaking 2 ~ 3h of 300 ~ 500mg/L, carries out vertical cuttage afterwards again.

Beneficial effect of the present invention:

1, the present invention adopts green wood cutting to carry out the breeding of kiwi fruit, therefrom prime of life individual plant is chosen raw spray then and ensures cuttage survival rate;

2, stay 1 ~ 2 blade to manufacture Nutrients uptake growth, as blade is excessive, can half be cut off, to reduce moisture evaporation;

3, cuttage branch of the present invention is in cuttage front lower end methyl α-naphthyl acetate aqueous solution soaking, can hestening rooting.
