Abstract

The invention provides a psidium guajave tree grafting method which comprises the following steps of selection of a scion and a seedling sapling stock, management before grafting of the seedling sapling stock, grafting, application of a grafting method and management after grafting. A seedling psidium guajave sapling is woody rooted and the root system of the sapling is relatively developed, so that the survival rate of grafting is ensured; the seedling psidium guajave sapling and a high-quality psidium guajave tree belong to the same family and the scion has strong affinity with the stock, so that the success rate of grafting is greatly improved and the growing speed of the grafted tree after grafting is also improved; the psidium guajave seedling sapling has strong drought resistance and low-temperature resistance and under the drought and low temperature conditions, the survival rate of grafting can be ensured, so that the grafted psidium guajave sapling can blossom and bear fruits one year after being transplanted and also has capacity that the grafted psidium guajave sapling can pass the winter in the air and is easy to survive after being transplanted. The method of grafting the psidium guajave sapling with the high-quality psidium guajave tree, which is provided by the invention, is simple and convenient and has the high survival rate; the coverage rate of the high-quality psidium guajave varieties is improved; popularization of the improved varieties of psidium guajave is implemented.

Description

A kind of guava grafting method
Technical field
The present invention relates to plant graft field, be specifically related to a kind of guava grafting method.
Background technology
In China, guava fruit is all the fruit that everybody likes through the ages, and because its taste is sweet and pure dense oiliness, and be also splendid tonic, fruit can be used as fresh eating.Guava attribute does not resist cold, therefore mostly intersperses among the torrid zone, the subtropics geographic region in Asia, the hillside of main product such as Guang Xidong, south and the southeast, Guangdong, Fujian and Taiwan one band in southern each province.Guava happiness is warm, and moistening weather is not cold-resistant.The minimum temperature that guava survives the winter is not less than 0 DEG C, once temperature is lower than 0 DEG C, the normal physiological activity of plant will be affected, and the absorbing capacity of root can weaken, and the spray of plant and blade can be made to wilt.
Guava treelet of growing directly from seeds is the fruit tree directly being planted growth by general guava seed, and the general age of tree all will just start to yield positive results more than 3 years, but the fruit born is little, yields poorly, and is tree-likely tall and bigly difficult to management, but well developed root system, nourish and grow vigorous.
Summary of the invention
The present invention aims to provide a kind of guava grafting method, and the method improves the drought-resistant ability of high-quality guava greatly, improves the fruit quality of guava and improves output, realizing the universal plantation of breeding guava.
Technical scheme of the present invention is as follows:
A kind of guava grafting method, comprises the following steps:
A, scion and Root-stock selection: high-quality guava branch is selected in scion, rugosity is 3 ~ 8mm; Root-stock selection inferior strain 1 year above guava of life is grown directly from seeds treelet, and mm is high for treelet of growing directly from seeds every strain mean height 200 ~ 300, and it is 10 ~ 20mm that rugosity is done in strain;
B, grafting prepare: grafting time selects the cloudy day in 1 ~ April, by the scion of high-quality guava branch by 1 ~ 3cm length, scion retain 1-2 full eyes; Removing blade;
C, grafting: scion is taken, scion lower end is whittled into inclined-plane, and inclined-plane becomes ligule, and bevel is level and smooth, and the degree of depth reaches xylem, and scion is grown by 1 ~ 3cm; Blocked from interface by stock, then cut out from section towards the epidermis of the south, the degree of depth is shown in xylem, and width is consistent with scion bevel; Scion is put into rapidly the stock xylem cutting out skin, 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 plastic sack by stock top to trapping to trunk 3-6cm, tighten, keep interface and scion moistening;
After the fringe bud of scion grows, cut opening at the plastic sack top of encapsulation scion;
The environmental temperature keeping grafting tree is 15 ~ 20 DEG C, and humidity is 65 ~ 80%;
The twig that timely pruning stock grows, ensures that scion is positioned at top.
Described in described steps A and step B, guava branch is lignified guava branch.
Moisturizing bag in described step C is the plastic sack that the white of 3cm × 6cm is commonly used.
After described step e, grafting 10 days, observe and survive situation, after grafting tree survives 20 days, removing plastic sack.
Described in described steps A and step B, guava strain bar is lignified high-quality guava branch.
Moisturizing bag in described step C is white plastic bag.
Preferred version of the present invention also comprises:
After step e, grafting 10 days, observe and survive situation, after grafting tree survives 20 days, removing moisturizing bag.
The present invention selects the stock of guava treelet of growing directly from seeds, and first because guava is grown directly from seeds treelet well developed root system, ensure that the survival rate of grafting; Secondly, stock and scion are all guava seeds, and scion is strong with stock affinity, significantly improve grafting success rate, also the growth rate of grafting tree after quickening grafting.Grow directly from seeds guava treelet and high-quality guava belongs to a section together, scion and stock affinity strong, significantly improve grafting success rate, also accelerate the growth rate of grafting tree after grafting; Guava treelet has stronger drought resisting anti-seismic design, non-irrigateier and compared with low temperature condition under all can ensure the guava after grafting to be reached the survival rate of grafting in 1 year and yields positive results, have open country simultaneously and pass the winter and transplant the ability easily survived; Fast growth after transplanting, the fruit born is large, taste is sweet, and mouthfeel is good; Produce fruit and can shift to an earlier date more than 3 years, output can improve more than 2 times, increases planting benefit.Guava of the present invention is grown directly from seeds, and treelet grafting high-quality guava method is simple and convenient, survival rate is high, improves the coverage rate of guava fine quality, realizes guava inferior strain and becomes breeding.After grafting survival, the fruit born can reach that taste is sweet, mouthfeel good.
In sum, the inventive method is simple and convenient, survival rate is high, greatly improves guava fruit quality, realizes guava fruit tree improved variety, improve plantation economic benefit.
