Method for cultivating stingless prickly ash strain

Abstract

The invention discloses a method for cultivating a stingless prickly ash strain. The method comprises the following steps: 1) material collection is selected in a dahongpao tea strain, branches which are born in the same year are shorn and taken, and full buds on the branches which are born in the same year are taken as scions; 2) grafting of tree stock seedlings is carried out, two-year dahongpao tea and wild prickly ash seedlings serve as tree stocks, the tree stock seedlings are planted in the year before the grafting according to 40cm*25cm planting space, before the grafting, small braches of the tree stock seedlings and the tip portion higher than 60-65cm of a trunk are cut out, the grafting is carried out at the 20cm position of the trunk, after the grafting, sealing and moisturizing are carried out through plastic thin film strips, and the grafting is carried out on the buds to enable the buds to be exposed out; 3) stingless prickly ash seedlings are preferably selected from the stingless prickly ash strain selected out from the grafting seedlings which are born in the same year, then number editing, listing and recording are carried out, multi-generation repeated grafting is carried out on the stingless prickly ash strain, and finally the stingless prickly ash strain which is stable in performance is cultivated.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a method for cultivating thornless prickly ash strains. Background technique [0002] Zanthoxylum bungeanum is a kind of spice plant belonging to the genus Zanthoxy L. of Rutaceae. It has a long history of cultivation in my country. It is not only a spice plant but also a traditional medicinal plant. Cultivated Zanthoxylum bungeanum has high economic value and soil and water conservation benefits. Zanthoxylum bungeanum is distributed in the provinces of the Yellow River, Yangtze River, and Pearl River basins, as well as Yunnan, Guizhou, and Tibet in China. According to the type of commodity, it can be divided into northern red pepper, southern green pepper and fragrant pepper produced in Shandong. [0003] About 2 million hectares of Zanthoxylum bungeanum have been planted in my country 2 , with an annual output value of about 60 billion yuan. Zanthoxylum bungeanum has become a...

Problems solved by technology

[0004] Since the 1950s, my country has successively improved varieties of Zanthoxylum bungeanum, and intermittently carried out research on the discovery and cultivation of varieties of thornless Zanthoxylum bungeanum.

In the early 1980s, my country introduced "Japanese prickly prickly ash" from Japan, and tried to plant it in Hebei, Henan and other places. In 2004, when Japan implemented an aid project in Sichuan, it was also introduced into Sichuan. In 2010, it was introduced from Hebei to Shaanxi Phoenix. County; because "Japanese prickly prickly ash" is essentially different from Chinese prickly ash, its numbness is insufficient, its yield is not high, its fruit surface glands are deeply sunken, and its cold resistance is weak. The green prickly ash in southern China and the red prickly ash in northern my country Zanthoxylum bungeanum has a strong aroma, high yield, and bulging fruit surface glands, so it has not been popularized and cultivated in the production of Zanthoxylum bungeanum in my country.
