In five artichoke as materials for the trial in Horqin sandy studied the growth rhythm of Jerusalem artichoke, and compare key indicators; from food, ecological value tested on five kinds of Jerusalem artichoke tubers nutrients, feed from the value of the test leaf nutrients, and its analysis and comparison; with red artichoke as materials, water-soluble alcohol precipitation through artichoke inulin studied the optimal extraction; studied artichoke cultivation mode of economic, ecological and economical models ecotype Mode 3 modes, each mode to determine the optimum cultivation conditions. The results showed that: (1) the growth of Jerusalem artichoke can be divided into three periods: 1-8 weeks after emergence, growth has stagnated for the period of slow growth artichoke, roots, stems, leaves and dry matter accumulation less; 9-18 weeks for the fast growing , Jerusalem artichoke rapid growth, stem, leaf dry matter accumulation, leaf area index while the rapid growth; 19-23 weeks tuber expansion period, tuber mass and volume increases rapidly, flowers emerge and mature, and stem and leaf dry matter content decreased, leaf area index also decreased rapidly. 5 kinds of artichoke, the red artichoke suitable as a sand-fixing plants. (2) Through the five kinds of composition of Jerusalem artichoke tubers comprehensive comparison, five varieties of Jerusalem artichoke, the red artichoke varieties suitable for use as eco-planting in arid sandy barren areas to improve the ecological environment, Changbai artichoke varieties suitable for the economy as a product development. By Ye component analysis and comparison of five kinds of artichoke leaves are not high-quality feed, can be used as normal diet, including red artichoke is most appropriate. (3) Extraction of water hot artichoke inulin optimum conditions as follows: solid-liquid ratio 1:10, temperature 90 ℃, extraction time 120min, liquid alcohol ratio 1:4. 4 factors liquid alcohol compared to inulin extraction yield the greatest impact, followed by solid-liquid ratio, extraction temperature, extraction time on artichoke inulin extraction rate had no significant effect. (4) Cheap cultivation model in order for the red artichoke varieties, planting density of 45,000 / ha, acre fertilizer 15kg for the best. Ecological Economy cultivation mode, varieties of Jerusalem artichoke and Bai Hongju taro choice of red, with red artichoke is the best, planting density select 42,000 / ha, dry season without fertilization, can make the artichoke in the sand land ecological effects of the combined effect of economic best. Eco-mode, red artichoke can dump waste dump and a better growth, the latter effect is better than the former.
