Method for graft-cultivating high-quality stingless pepper tree

Abstract

The invention belongs to the field of economic tree grafting technologies, and provides a method for graft-cultivating a high-quality stingless pepper tree. The method comprises the following steps: (1) cultivating a stock seedling; (2) cultivating a grafting seedling; (3) cultivating a stingless pepper strain; (4) establishing a garden and planting; (5) managing the garden; (6) pruning; and (7) preventing and treating plant diseases and insect pests. The method is capable of using eight months of a pepper tree as a stock, graft-improving six months of a Da Hong Pao tree and five months of a Mei Hua pepper tree, and acquiring a stingless pepper seedling with stable characters, and using a wild pepper seedling as a stock again before establishing the garden and planting, enabling a breedingstingless pepper seedling scion to obtain a second-turn-grafted stingless pepper seedling through the grafting, wherein the stress resistance of the second-turn-grafted stingless pepper seedling is remarkably enhanced, the lifetime, the yield and the quality of the second-turn-grafted stingless pepper seedling are remarkably improved, the age of the pepper tree is about 25 years, the single treeyield in a full productive stage is up to 3.2 Jin in average, the stingless pepper tree has the characteristics of strong disease resistance, drought resistance and water logging resistance, the stingless pepper tree can be generally grown in drought or damp areas below 1800 meters of an altitude, and can be planted and survived in a site where an original pepper tree is dead, and an occurring rate of root rot is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of grafting of economic forest trees, in particular to a method for cultivating high-quality thornless pepper trees by means of grafting to improve strains and improve quality and efficiency. Background technique [0002] Zanthoxylum bungeanum is a deciduous small tree of the Rutaceae Zanthoxylum genus, with thorns on the stem and branches, and purple-red fruit. It is cultivated in most parts of the country and widely distributed. Its peel can be used as seasoning, and aromatic oil can be extracted, and it can be used as medicine. The seeds are edible, and can also be processed to make soap. Zanthoxylum bungeanum is used as a traditional Chinese medicine. It has the effects of warming the middle and promoting qi, expelling cold, relieving pain, and killing insects. Zanthoxylum bungeanum is resistant to drought and cold, and likes sunshine. It is suitable for warm and humid soil with deep fertile loam and s...

Problems solved by technology

[0004] There are several shortcomings or disadvantages in the existing pepper trees in Wudu District: first, the life span is short, and the average tree age is generally about 10 years; It is not easy to pick, and the cost of picking is high; Fourth, after the death of the pepper tree, it is not easy to replant it in situ, resulting in a decrease in the total area

The above problems existing in the existing pepper trees have resulted in severe early death of peppercorns, difficulty in renewal, and long-term consolidation of the industrial area; degeneration of varieties and decline in quality; industrial labor costs (mainly referring to picking costs) have risen
