Method for cultivating less-thorn Zanthoxylum armatum DC.

Abstract

The invention discloses a method for cultivating less-thorn Zanthoxylum armatum DC. The method comprises the following steps: (1) rootstock cultivation; (2) rootstock treatment; (3) scion selection; (4) scion treatment; (5) grafting; (6) final-period management; and (7) multi-generation grafting. According to the grafting method provided by the invention, through more than three generations of grafting, the less-thorn Zanthoxylum armatum DC. with stable characters, high yield, strong stress resistance and good quality can be cultivated, compared with traditional Zanthoxylum armatum DC. (seedling), the less-thorn Zanthoxylum armatum DC. has the characteristics that thorns on branches are less by 80% or above, the widths of the thorns are smaller by 30%, the lengths of the thorns are smallerby 35%, rachis thorns and blade thorns are less by 100%, and therefore, rachis and blades do not have thorns.

Description

technical field

[0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for cultivating rattan pepper with few thorns. Background technique

[0002] Sichuan Zanthoxylum bungeanum has a long history of cultivation, high quality and wide range of uses. The fruit is well-known at home and abroad for its unique flavor of bright color, large oily grains, rich aroma, crisp and numb taste, and pure numbness. It is the soul of Sichuan cuisine. Sichuan peppercorns widely cultivated now mainly include Zanthoxylum bungeanum Maxim. series, also known as "red peppercorns", such as "Hanyuan peppercorns", "Lingshan Zhenglu peppers", "Maoxian peppercorns" and other fine varieties; bamboo leaf peppercorns ( Zanthoxylum armatum DC.) series, also known as "green pepper", such as "Jinyang green pepper", "Pengxi green pepper", "vine pepper" and other varieties.

Embodiment 1

[0039] A kind of cultivation method of rattan pepper with few thorns, comprising the following steps:

[0040] (1) Rootstock cultivation

[0041] a. Select the green pepper or rattan pepper with a tree age of more than 10 years, strong growth, no pests and diseases, and high yield as the mother tree for seed collection. After the seeds are harvested manually, dry them in the shade and take the seeds, soak them in water for 5 to 8 days to promote germination;

[0042] b. Plow the soil for more than 20cm, then level the site, spray with 70% thiophanate-methyl 800 times liquid to disinfect the soil, and then cover and seal it with plastic film for 5-7 days;

[0043] c. Arrange the sterilized soil according to the slope direction to form a seedbed with a width of 80cm and a height of 10cm. The length of the seedbed depends on the terrain. The ditch between the seedbeds is 20cm wide and 10cm deep, which is conducive to tending management and drainage;
