Embodiment 1

[0018] A kind of propagation method of Jerusalem artichoke comprises the steps:

[0019] 1. Divide the Jerusalem artichoke tubers into tubers of more than 2 cubic centimeters, each piece needs to have 1-2 bud eyes, sterilize and plant them densely in the seedling bed, and cover them with plastic film to keep warm and accelerate the seedlings. When the seedlings grow to 15-20 cm, Seedlings can be cut into sections; each cut must have 3-4 leaves at the tip.

[0020] 2. Prepare humus soil, neutralize the humus soil to a pH value of 5.3, then add fertilizer-trace and major elements to 1000 parts of humus soil, the dosage is as follows: 300 parts of ammonium phosphate, 150 parts of ammonium nitrate, molybdenum 3 parts of ammonium sulfate, 450 parts of potassium sulfate, 350 parts of magnesium sulfate, 45 parts of iron sulfate, 50 parts of copper sulfate, 10 parts of zinc sulfate, 5 parts of boric acid, 4 parts of manganese sulfate, 4000 parts of shale ash; then spray water and mix ...

Embodiment 2

[0026] Except that the preparation ratio of humus is different from Example 1, all the others are the same as Example 1. The humus is neutralized to a pH value of 4.8, and then fertilizer-trace and macroelements are added to 1000 parts of the humus, and the consumption is as follows: 450 parts of ammonium phosphate, 2 parts of ammonium molybdate, 350 parts of potassium sulfate , 450 parts of magnesium sulfate, 55 parts of iron sulfate, 35 parts of copper sulfate, 6 parts of zinc sulfate, 7 parts of boric acid, 3 parts of manganese sulfate, and 5000 parts of shale ash.

Embodiment 3

[0028] Except that the preparation ratio of humus is different from Example 1, all the others are the same as Example 1. The humus is neutralized to a pH value of 5.8, and then fertilizer-trace and macroelements are added to 1000 parts of the humus, the amount of which is as follows: 540 parts of ammonium phosphate, 100 parts of ammonium nitrate, 1 part of ammonium molybdate , 500 parts of potassium sulfate, 550 parts of magnesium sulfate, 35 parts of iron sulfate, 45 parts of copper sulfate, 12 parts of zinc sulfate, 6 parts of boric acid, 5 parts of manganese sulfate, and 3000 parts of shale ash.

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...
