New Food and Medicine Homologous Vegetable Variety'Songyou No.1'and Its High-yield Cultivation Technologies
In order to build the'shopping basket program'of Hexi Corridor and enrich the type of vegetable,a new food and medicine homologous vegetable variety'Songyou No.1'was introduced from Huazhong Agricultural University.The trial planting of the new variety was successful at Guangdong-Hong Kong-Macao Greater Bay Area production base in Jiuquan city,and the product was favored by the southern market.This variety is a distant hybrid of Brassica napus and Isatis indigotica,with the characteristics of well-developed root system,large plant type,plant height of 60-120 cm,leaf width of 65-80 cm,cold resistance but heat labile,strong disease resistance and extremely strong germination ability of axillary bud.Both the main and side flowering stems can be harvested and the harvest period is relatively long.By studying the crop growth habits of'Songyou No.1',a standardized cultivation technology has been established from the aspects of site selection,stubble arrangement,sowing method and field management,achieving sustained high yield of'Songyou No.1',with the flowering stems yield of each stubble of 2 445.5 kg per 667 m2 and a net profit of 17 346 yuan per 667 m2.The economic benefit is significant,and it is suitable for large-scale promotion in the cold and cool areas of the central Hexi Corridor in Gansu province and similar areas.
