specific Embodiment approach 1

[0028] A method for preserving Jerusalem artichoke germplasm resources, comprising the steps of:

[0029] Step 1. Select a soil field with a pH of 7.0 to 9.0. After leveling the land, dig a seeding pit at the position to be sown, and plant Jerusalem artichoke by means of the seeding pit;

[0030] Step 2, lay polyvinyl chloride woven bags in the seeding pit dug in step 1;

[0031] Step 3, add sowing soil in the polyvinyl chloride woven bag laid in step 2, and fill up the whole sowing pit with the sowing soil;

[0032] Step 4, sowing Jerusalem artichoke seed potatoes in the sowing soil in the polyvinyl chloride woven bag prepared in step 3;

[0033] Step 5. After emergence, when the height of the seedlings is 25-35 cm, topdress the seedlings in the sowing pit, and keep the sowing pit free of weeds;

[0034] Step 6, after the Jerusalem artichoke is mature, the whole polyvinyl chloride woven bag and the sowing soil are taken out, and the mature Jerusalem artichoke seed potato is...

Abstract

The invention discloses a jerusalem artichoke germplasm resource conservation method, and belongs to the technical field of jerusalem artichoke germplasms. The jerusalem artichoke recovery difficulty is large, harvesting cannot be completed, seedling germination of tubers remaining in a field can be achieved directly next year, the germplasm resource conservation purity is not high, the mixing phenomenon is serious, and variety resource conservation and potato seed propagation are directly limited. The method comprises the following steps that seeding pits are selected for germplasm resource conservation; polyvinyl chloride woven bags are laid inside the seeding pits; the polyvinyl chloride woven bags are filled with seed sowing soil; jerusalem artichoke tubers are sown inside the seed sowing soil; the polyvinyl chloride woven bags and the seed sowing soil are taken out for tuber harvesting; according to different varieties, subpackaging is performed, shallow burying and depoting are achieved for seed sowing in the next year. The sufficient soil environment is provided for jerusalem artichoke tuber growth, the tuber growth range is well limited, harvesting and conservation of germplasm resources are promoted, the germplasm resource purity is ensured, and meanwhile the influence of tubers remaining in soil on crops in the next season is avoided.

Description

technical field [0001] The invention belongs to the technical field of Jerusalem artichoke germplasm, and in particular relates to a method for preserving Jerusalem artichoke germplasm resources. Background technique [0002] Jerusalem artichoke is a perennial herb of the genus Sunflower in the Compositae family, commonly known as Jerusalem artichoke, devil ginger, ground ring, etc. Jerusalem artichoke likes fertile soil, but it is also resistant to barrenness and salt and alkali; it likes humidity, but it is also drought-tolerant; it likes warmth, but it is also cold-resistant. Jerusalem artichoke has strong ecological adaptability and can grow in deserts, tidal flats and saline-alkali lands. It is one of the few saline-alkali-resistant, high-yielding, high-density energy plants. It has the characteristics of not expropriating land with food crops, and is called green oil. . The above-ground stems can also be added to work feed, and are called "the common crops for humans...
