Cultivation method of species of jeruselem artichoke

Abstract

The invention relates to a Helianthus tuberosus variety breeding method, which belongs to the plant variety breeding technology field. The recyclable seawater stress cultivation is used, and the consistence of the seawater is set into six kinds of consistence: 0 percent, 10 percent, 25 percent, 50 percent, 75 percent, and 100 percent. Seawater is filtered repeatedly and systematically in the field, and the breeding object is the salt-resistant high-yield and high-quality. The south Helianthus tuberosus No.1 bred into after six generations grows strongly in the ratio of 3 to a thousand about salt soil, has strong salt resistant property and thick stalk, and has about ten branches 1m beneath the ground; the underground tuber has thin skin and more than ten bud eyes; the yield per mu is about 3000kg without pests. The dry weight of the tuber is 23-29 percent of the fresh weight. The variety has high yield, excellent quality, and strong salt resistance; can be cultivated in the coastal beach saline alkali soil or the inland saline alkali soil; can have broad application prospect in the fields of bio-energy plant material in our country, and can promote the development of related industries.

Description

1. Technical field [0001] The invention relates to a method for cultivating Jerusalem artichoke varieties, and belongs to the technical field of plant variety breeding. It is specially used for the cultivation of the biomass energy plant Jerusalem artichoke-Nanyu No. 1. 2. Background technology [0002] Jerusalem artichoke is a cultivated species that can form underground tubers in the genus Sunflower of the family Compositae. It is also known as sea ginger, artichoke, devil ginger, etc., and its scientific name is Helianthus tuberosus L. There is distribution and cultivation of Jerusalem artichoke, which can be cultivated in eighteen provinces including northeast my country, Inner Mongolia, Hebei, Henan, Zhejiang, Sichuan, Shandong, Jiangxi, Guangdong, Guangxi and Shaanxi. Jerusalem artichoke likes warmth, but it is cold-resistant; it likes humidity, but it is drought-tolerant; it likes fertility, but it is resistant to barrenness and salt-alkali. Tubers germinate at 6-7°C...

AI Technical Summary

Problems solved by technology

However, the existing wild Jerusalem artichoke varieties have poor salt tolerance, low yield, and low sugar content, and cannot be popularized and planted in coastal beaches. However, the varieties bred by the Nanyu No. 1 cultivation method have strong salt tolerance, high yield, and high quality. Well, it is suitable for promoting planting on non-cultivated coastal tidal flats with high salt content. Using coastal tidal flats or inland saline-alkali land to plant energy plants, Jerusalem artichoke, will have a very wide range in the efficient use of tidal flat resources in my country and the adjustment of biomass energy plant raw materials in my country. It can promote the development of related industries and obtain greater economic, social and ecological benefits.
