Breeding method of jerusalem artichoke

Abstract

A method for reproducing Jerusalem artichoke culturing seedlings on vernalization bed until the seedling has 15-20 cm in height, cutting the seedling into segments, culturing seedlings with said segments in the culture medium prepared from humas soil, fertilizer, trace elements and macro elements, and transplanting by hole sowing with soil. Its advantage is high survival rate. Said Jerusalem artichoke can be used to prevent soil erosion.

Description

technical field [0001] The invention relates to a plant propagation method, in particular to a propagation method of the Jerusalem artichoke plant which prevents land desertification, prevents water and soil loss, and prevents and controls sand. Background technique [0002] Jerusalem artichoke is a perennial herb of Compositae, with luxuriant stems and leaves, and the total biomass can reach 5-7 tons / mu. Naturally growing Jerusalem artichokes, in general, grow in bushy clusters. Stems tough, thick black, tall. The leaves are black and green, lush. The cold resistance is very strong, the tubers sown in the ground at minus 40-50 ℃ dormant and can continue to germinate in the second year; the drought tolerance is strong, when the drought is severe, the stems and leaves of the Jerusalem artichoke on the ground die, and the underground stems can grow again in the second year. Growth and emergence; anti-wind and sand, as long as the sandy soil is not more than 50 cm, it can st...

Problems solved by technology

[0004] At present, the artifical propagation technology of Jerusalem artichoke is still lacking, so the cultivation of Jerusalem artichoke cannot be promoted in a large area.
