Abstract
The invention provides an inferior litchi tree top grafting method which comprises the following steps of scion and seedling tree stock selecting, stock grafting pre-managing, grafting, grafting method and grafting post-managing. A seedling litchi tree has an arbor root and has a developed root, and the survival rate of grafting is guaranteed. The seedling litchi tree and a superior litchi tree belong to the same family, a scion and a stock are strong in compatibility, the successful rate of grafting is greatly improved, and the growing speed of grafting seedlings after grafting is accelerated; the litchi tree has a strong drought and low temperature resistant ability, the survival rate of grafting can be guaranteed under a dry and low temperature condition, so that the litchi tree after grafting can blossom and yield fruits within a year and has the abilities of passing the winter in an open field and blossoming and yielding the fruits just in one year. The inferior litchi tree grafting method is simple, convenient and high in survival rate, the coverage of high quality litchi trees is improved, and the inferior litchi tree can be changed into the superior litchi tree.
Description
Technical field
The present invention relates to plant graft field, be specifically related to a kind of method of litchi high position grafting inferior.
Background technology
In China, litchi fruits is the fruit that everybody likes since time immemorial, covers its taste sweet and pure dense oiliness, and is also splendid tonic, and fruit can in order to bake as garden, osmanthus meat, dried fruit.Its property of plant in lichee Pterostyrax 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.Litchi happiness is warm, and moistening weather is not cold-resistant.The minimum temperature that litchi 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.
Litchi inferior is the fruit tree directly being planted growth by general Litchi chinensis Seeds, and the general age of tree all will just start to yield positive results more than 8 years, but the fruit born is little, and meat is thin, and core is large, yields poorly, and tree-like tall and big being difficult to manages, but well developed root system, nourish and grow vigorous.
Summary of the invention
The present invention aims to provide a kind of litchi high position grafting method inferior, and the method improves the drought-resistant ability of high-quality lichee greatly, improves the fruit quality of litchi and improves output, realizes the plantation that inferior strain lichee becomes breeding lichee.
Technical scheme of the present invention is as follows:
The method of lichee seedling tree high position grafting high-quality lichee inferior, comprises the following steps:
A, scion and Root-stock selection: high-quality lichee branch is selected in scion, rugosity is 5 ~ 10mm; The lichee seedling tree that the life in 6 years of Root-stock selection inferior strain is above, the average limb of the every strain of seedling tree reaches more than 6, and limb rugosity is 20 ~ 30mm;
B, grafting prepare: grafting time selects the cloudy day in 1 ~ April, by the scion of high-quality litchi branch by 2 ~ 5cm length, scion retain 2-3 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 scion is grown by 2 ~ 5cm; 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 10-15cm, 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 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, litchi branch is lignified litchi branch.
Moisturizing bag in described step C is the plastic sack that the white of 10cm × 15cm is commonly used.
After described step e, grafting 20 days, observe and survive situation, after grafting survives one month, removing plastic sack.
Described in described steps A and step B, litchi branch is lignified high-quality litchi branch.
Moisturizing bag in described step C is white plastic bag.
Preferred version of the present invention also comprises:
After step e, grafting 20 days, observe and survive situation, after grafting survives one month, removing moisturizing bag.
The present invention selects inferior strain to grow directly from seeds the stock of litchi, first due to lichee seedling tree well developed root system, ensure that the survival rate of grafting; Secondly, stock and scion are all lichee seeds, and scion is strong with stock affinity, significantly improve grafting success rate, also the growth rate of grafting after quickening grafting.Grow directly from seeds litchi and high-quality litchi belongs to a section together, scion and stock affinity strong, significantly improve grafting success rate, also accelerate the growth rate of grafting after grafting; Litchi has stronger drought resisting anti-seismic design, non-irrigateier and compared with low temperature condition under all can ensure the litchi after grafting to be reached the survival rate of grafting in 1 year and yields positive results, have the ability that open country is passed the winter and yielded positive results then simultaneously; The fruit born is large, meat is thick, taste is sweet, and output can improve more than 2 times, reduces biennial fruiting phenomenon.Lichee of the present invention seedling tree high position grafting inferior high-quality lichee method is simple and convenient, survival rate is high, improves the coverage rate of lichee fine quality, realizes lichee inferior strain and becomes breeding.After surviving after high position grafting, the fruit born can reach that taste is sweet, meat is thick, core is little.
In sum, the present invention lichee seedling tree inferior high position grafting high-quality lichee method is simple and convenient, survival rate is high, greatly improves litchi fruits quality, realizes the improved variety of lichee fruit tree.
