High-yield cultivation method for stingless wild peppers

Abstract

The invention discloses a high-yield cultivation method for stingless wild peppers. The high-yield cultivation method comprises the following steps of (1) seedling nursery land selection, wherein a sheltered sunny slope, a sheltered semi-sunny slope or a sheltered ridge edge is selected, the land with abundant sunlight and deep and fertile soil layers is selected, the gradient is from 15 degrees to 30 degrees, and the land is built into a terraced field or prepared; (2) seed collection, wherein plump fruits fully matured are collected from a seed tree which is excellent in variety and free from diseases and insect pests and grows strongly, and then seeds are taken out from the fruits after the fruits are dried in the shade; (3) seedling cultivation, wherein a ditching and strip sowing mode is adopted, sowing is carried out according to the line spacing of 20-25 cm, the planting distance of 10-15 cm, and the ditch depth of 3-5 cm, and the planting number is 675-1650 plants / hm<2>; (4) fertilizer application, wherein 5-10 kg of farm manure, 0.5-0.15 kg of urea and 0.1-0.2 kg of phosphate fertilizer are applied for each seedling; (5) pest control, wherein in the second half of May and June, 2.5% of deltamethrin cream in 4000-fold liquid and omethoate in 2000-fold liquid are respectively used for spraying a crown once; (6) harvesting, wherein five to seven years after planting, harvesting is carried out in batches according to the maturity. According to the method, the yield of the stingless wild pepper is increased, and the high-quality stingless wild pepper can be produced.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a high-yield cultivation method for thornless Zanthoxylum bungeanum. Background technique [0002] Thornless Zanthoxylum bungeanum is native to my country and has a long history of cultivation. It is mainly planted in low mountains and hills, on the edge of terraced fields and around courtyards. It likes sunshine and is resistant to drought. It is planted on the edge of terraced fields with dense branches and leaves, well-developed root system, and has a great role in maintaining water and soil. Its whole body is full of treasures, and its roots, stems, leaves, flowers, and fruits contain a lot of hemp flavorings and aromatic oils. With the increase in edible and medicinal use of Zanthoxylum bungeanum and the increase in foreign trade exports, since the 1990s, scientific research departments have carried out research on the breeding of improved varieties of Zanthoxylum bun...
