To explore the development prospect of energy plant Helianthus tuberosus in saline-alkali area,two test materials-cultivated and wild Helianthus tuberosus were cultivated in Songnen Plain for experiments and study,which include treatments of fertilization,mowing,heavy saline-alkali stress and soils with different plowing years.The results showed that the two species both could grow and propagate normally in moderate saline-alkali land.Fertilization and mowing were beneficial for growing of Helianthus tuberosus.Heavy saline-alkali stress would decrease emergency rate of Helianthus tuberosusseedling.The wild species showed better resistance under heavy saline-alkali stress.The yield of cultivated species could reach more than 30 000 kg·hm-2 in moderate saline-alkali land.In conclusion,Helianthus tuberosus was an excellent energy plant fitting for cultivating in Songnen Plain.
