Grafting method of Cyclocarya paliurus

Abstract

The invention discloses a cyclocarya paliurus grafting method and relates to a plant grafting technique. The grating method includes: firstly, selecting a pterocarya stenoptera tree as a stock prior to selecting superior cyclocarya paliurus grown branches, cutting off the branches to serve as grafting scions with one to three sprouts reserved on each scion, cutting a graft union at the lower end of each scion to be U-shaped, and cutting away a wood layer at least on one side of each graft union with the cut surface 4-5cm in length; secondly, cutting off the stock, smoothing the section, splitting a cut portion with pruning shears, inserting each scion into a split seam, aligning the scions to a stock cambium, and binding a coincide portion with a special cloth strip; finally, after survival of grating, removing branch buds sprouting from the stock in time, pinching and unbinding after young sprouts grow to 19.5-20.5cm, binding a support so as to avoid wind breakage. The pterocarya stenoptera tree is selected as the grafted stock to be grafted in suitable season, survival rate of grating of the cyclocarya paliurus is increased from 50% to 90%, artificial cultivation of the cyclocarya paliurus is realized, and the grafting method is simple to operate and easy to popularize.

Description

technical field [0001] The invention relates to plant grafting techniques, in particular to a method for grafting Cyclocarya paliurus. Background technique [0002] Cyclocarya paliurus is a deciduous tree with a height of 10-30 meters; the bark is gray; the branches are dark brown, the flowering period is 4-5 months, the leaves are leathery, the singular pinnate leaves are 25-30 cm long, and the fruit is leathery Horizontal disc-shaped wings, fruit ripening period from July to September, Cyclocarya paliurus is known as the giant panda in the plant world, and the third tree in the medical field. China: Cyclocarya paliurus bud leaves contain a chain of original ecological hypoglycemic factors, which are mainly composed of two original ecological nutrients: inorganic nutrients and organic nutrients, which can effectively and comprehensively regulate the body's glucose metabolism. Qianliu tea has many functions such as lowering sugar, lowering fat, lowering blood pressure, impr...

[0002] Cyclocarya paliurus is a deciduous tree with a height of 10-30 meters; the bark is gray; the branches are dark brown, the flowering period is 4-5 months, the leaves are leathery, the singular pinnate leaves are 25-30 cm long, and the fruit is leathery Horizontal disc-shaped wings, fruit ripening period from July to September, Cyclocarya paliurus is known as the giant panda in the plant world, and the third tree in the medical field. China: Cyclocarya paliurus bud leaves contain a chain of original ecological hypoglycemic factors, which are mainly composed of two original ecological nutrients: inorganic nutrients and organic nutrients, which can effectively and comprehensively regulate the body's glucose metabolism. Qianliu tea has many functions such as lowering sugar, lowering fat, lowering blood pressure, improving immunity, etc. However, there is no mature method for the artificial cultivation of Cyclocarya paliurus at present, and the conditions required for germination of Cyclocarya paliurus seeds are very harsh, The rate is very low, and for the grafting of Cyclocarya paliurus, people have not found a suitable rootstock, and the grafting survival rate of Cyclocarya paliurus is almost zero.
