Abstract
The invention provides a psidium guajave tree grafting method. The psidium guajave tree grafting method comprises following steps of scion and rootstock selection; grafting preparation; grafting; and management after grafting. A seedling psidium guajave sapling has an arbor woody root, the root system of the sapling is developed, and the grafting survival rate is guaranteed; the seedling psidium guajave sapling and a high-quality psidium guajave sapling belong to the same family and the scion has strong affinity with the stock, so that the success rate of grafting is greatly increased and the growing speed of the grafted sapling after grafting is also increased; the psidium guajave seedling sapling has strong drought resistance, and under the drought condition, the grafting survival rate can be ensured, so that the grafted psidium guajave sapling can blossom and bear fruits within two years. The method of grafting the seedling psidium guajave sapling with the high-quality psidium guajave sapling is simple and convenient and has the high survival rate; the coverage rate of the high-quality psidium guajave varieties is increased; and the fact that the psidium guajave tree blossoms and bears fruits in advance is achieved.
Description
【Technical field】
The present invention relates to plant graft field, and in particular to a kind of engrafting method of guava.
【Background technology】
Guava, is Psidium Myrtaceae, is evergreen dungarunga or shrub, is commonly called as pulling out guava, that pulls out.Mellow fruit
Real light green, delicate fragrance is good to eat.Fructus psidii guajavae immaturus thin skin, yellow green, pulp is thick, and fresh and sweet crisp and refreshing, the little seed of the heart is few, and fruits nutrition is rich
Richness, containing the trace element such as higher vitamin A, C, cellulosic and phosphorus, potassium, calcium, magnesium, in addition fruit be also enriched in protein and
Lipid.Luxuriant Punica Myrtaceae deciduous tree, kind is a lot of, wherein optimal with " famille rose ". it in addition to rich in moisture, also one
Quantitative protein, glutamic acid, fat, carbohydrate and calcium, phosphorus, Iron and Vitamin A, B, C etc., and especially with Vitamin C content
At most. according to analysis, luxuriant pomegranate is average to contain 125～180 milligrams of vitamin C, the about three times of citrus per hectogram pulp. therefore, foreign countries doctor
The useful luxuriant juice of my pomegranate of scholar makees baby's beverage. and arctic expedition team member everyone luxuriant pomegranate powder of the ounce of dispensing 4, then can ensure three months
Ascorbic requirement. luxuriant pomegranate fruit color is delicate and charming, fine and tender taste, smell delicate fragrance. in addition to being available for eating raw, may also be fabricated which jam, jelly
And fruit juice etc., can also make medicinal, with astringing to arrest diarrhea, hemostasis, antipruritic work(is cured mainly and had loose bowels, protracted dysentery, eczema, the disease such as traumatic bleeding. to changing
Kind diabetic symptom also has preferable effect. and pomegranate leaf and bark, tree root also can be used as medicine. hyperhydrochloria and stomachache can be controlled.
Traditional guava method for culturing seedlings is directly sowed with seed, and the seedling for breeding out is the fruit seedling that grows directly from seeds.General practicality fruit seedling
Exist result late, yield poorly, the big unmanageable of high crown height the shortcomings of, but well developed root system, nutrient growth is vigorous.
【The content of the invention】
For the problem that the practicality nursery of above guava is present, the present invention is intended to provide a kind of engrafting method of guava, the method
The drought-resistant ability of high-quality guava is greatly improved, Blooming result improves the fruit quality of guava seedling and improves yield, real
Existing inferior strain guava becomes the implantation methods of breeding guava.
1st, technical scheme is as follows：The method of guava seedling grafting high-quality guava inferior, comprises the following steps：
A, scion and Root-stock selection：Scion is cut from high-quality guava, and rugosity is 3～5mm；Stock is selected more than life in 0.5 year
Guava seedling, per plant of seedling averagely cuts dry height in more than 15cm, and it is 10～20mm to cut dry crude degree；
B, grafting prepare：Grafting time selects the cloudy day in 1～April, and high-quality guava is cut into the scion by 1～3cm length,
Retain 1-2 full eye in scion；Remove blade；
C, grafting：The scion epidermis of more flat one side is reamed, bevel 0.5～1.0cm, 0.2～0.5cm of length and width, depth has just arrived wood
Matter portion；Scion by 1～3cm length；The position for selecting diameter of stock more slightly larger than scion blocks on stock, then from section court
Cut out to epidermis in the south, depth has just been shown in xylem, and width is consistent with scion bevel；Scion is put into rapidly the stock for cutting out skin
In xylem, the both sides of scion bevel and stock are cut game clock skin xylem both sides and are fitted like a glove, with Polypropylence Sheet colligation interface；
D, managing after grafting：With polybag from stock top to trapping to 2～3cm of trunk, tighten, keep interface and scion
Moistening；
After the fringe bud of scion grows, at the top of the polybag of encapsulation scion opening is cut；
The environment temperature for keeping grafting is 15～20 DEG C, and humidity is 65～80%；
What in time pruning stock grew cuts bud, it is ensured that scion is located at top.
2nd, the method for guava seedling grafting high-quality guava as claimed in claim 1, it is characterised in that：Step A with
The slitting of guava seedling described in step B is lignified guava seedling slitting.
3rd, the method for guava seedling grafting high-quality guava as claimed in claim 1, it is characterised in that：The step
Moisturizing bag in C commonly uses less polybag for the white of 5cm × 10cm.
4th, the method for guava seedling grafting high-quality guava as claimed in claim 1, it is characterised in that also include：
20 days after step E, grafting, observation survives situation, 15 days after grafting survives, removes polybag.
The present invention is primarily due to guava seedling well developed root system from the stock of guava seedling of growing directly from seeds, it is ensured that grafting is survived
Rate；Secondly, stock and scion is all guava seed, and scion is strong with stock affinity, greatly improves grafting success rate, also adds
The growth of grafting and speed of yielding positive results after fast grafting.The guava seedling that grows directly from seeds belongs to a section, scion and anvil together with high-quality guava seedling
Wooden affinity is strong, greatly improves grafting success rate, also accelerates the speed of growth of grafting after grafting；Guava seedling has stronger
Drought resisting anti-seismic design, it is non-irrigateier and compared with low temperature under conditions of can all ensure the survival rate of grafting so that kind stone after grafting
Pomegranate seedling can reach in 4 years and yield positive results；The fruit born is big, meat is thick, taste is sweet, Blooming result more than 3 years.This
Invention guava seedling grafting high-quality guava method is simple and convenient, survival rate is high, improves the covering of guava fine quality
Rate, realizes guava Blooming result.After surviving after grafting, the fruit born can reach that fruit is big, taste is sweet, meat is thick.
In sum, a kind of engrafting method of guava of the invention is simple and convenient, survival rate is high, greatly improves guava and becomes civilized knot
Fruit time and fruit quality, realize Fructus psidii guajavae immaturus seedling improved variety.
