Breeding method of jerusalem artichoke

Abstract

The invention relates to a propagation method of Jerusalem artichoke. The method comprises the following steps: (1) taking seedlings in a germination bed to make the sprouts grow to about 15-20 centimeters, taking the seedlings and cutting them into sections and then raising them; (2) cutting them into sections and raising them The culture medium is humus soil plus fertilizer, trace elements and macroelements; (3) The method of hole sowing with soil is generally used in cultivation, and the survival rate is high; Collection method. The invention improves the efficacy of Jerusalem artichoke planting in preventing land desertification, preventing water and soil loss, preventing and controlling sand and improving planting structure.

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.
