Method for grafting big Chinese evergreenchinkapin trees

Abstract

The invention discloses a method for grafting big Chinese evergreenchinkapin trees. The method is characterized by comprising the steps of (1) truncation of the big chestnut trees; (2) cultivation ofnew shoots; (3) scion preparation; (4) stock treatment; (5) grafting; (6) post-grafting management; the survival rate of grafting can be as high as 95% through the above-mentioned method, the graftingefficiency is greatly improved, a large number of thick branch groups are grown in the same year when the grafting is performed to form a full crown, and a large number of fruits are born in the second year. The problems in the prior art of low survival rate of the grafting of the Chinese evergreenchinkapin trees, the need for many years of multiple grafting, the complex grafting process, the lowefficiency, the time-consuming and labor-consuming management after grafting and the slow growth and recovery of the tree body are effectively solved.

Description

technical field [0001] The invention relates to the field of fruit tree grafting, in particular to a method for regrafting large chestnut trees. Background technique [0002] Chestnut ( Castanea Henryi Rehd. et Wils) belong to Fagaceae (Fagaceae) chestnut genus ( Castanea Mill.) plant, a unique species in my country, is a famous dried fruit and woody food tree species in southern China. Its nuts are conical in shape, unique in flavor, rich in starch, protein, soluble sugar, and various vitamins and trace elements needed by the human body. , high nutritional value. Because the quality of the chestnut is better than most of the southern chestnut varieties, it is especially suitable for fresh eating, sugar frying and processing, and is deeply loved by the masses in the south. Because of its high economic benefits, it has gradually become an important economic forest for forest farmers in the southern mountainous areas of my country to get rid of poverty and become rich. spec...

Problems solved by technology

[0007] The present invention solves the problems of inconvenient operation, complex procedures for reshaping and dwarfing tree shapes in the existing high-grafting and replanting technology, and the traditional grafting method has complicated procedures, low grafting efficiency, and frequent gaps between the scion and the rootstock. The xylem is cut unevenly and can’t be fully fitted, resulting in gaps, easy to shift when bandaging the wound, difficult to form callus between the scion and the rootstock, resulting in the death of the scion, and low survival rate of grafting. The method of regrafting large chestnut trees with high yield, simple operation, labor-saving, and rapid formation of dwarf and high-yield tree shape and results effectively solves the problem of low survival rate of chestnut grafting in the prior art, which requires many years of grafting and complicated grafting procedures. , low efficiency, time-consuming and labor-intensive management after connection, and slow growth and recovery of trees
