Abstract:Through the comparative analysis of the water content, protein content and oil content in the seeds of 13 oil- sunflower cultivars, the results showed that the average water content was 38.2 g/kg, the average protein content was 154 g/kg and the average oil-content was 440.2 g/kg. Comprehensive comparison, the grain protein content and oil content of jinfengyou 6 and Baofengyou 9 sunflower cultivars used in oil were higher and had better nutritional quality.

欧洲防风(Pastinaca sativa)别名美洲防风、芹菜萝卜[1 ],肥大的肉质根可炒食、煮食或做汤[2 ],是一种低热量高膳食纤维的营养型蔬菜,富含叶酸、钾、锌等多种矿物元素及维生素。作为一种特色蔬菜,因其富含叶酸并兼备防癌功效,食用性好且营养丰富,在欧美等国家深受喜爱。天水地区属温带半湿润半干旱气候过度区域,年均气温10.7 ℃,年降水量480~610 mm[3 ]。为丰富市民菜篮子,调整当地蔬菜产业结构,我们通过天津先优达种子有限公司引进欧洲防风,通过开展种植密度、覆盖模式、田间管理等试验研究,总结出了适宜天水地区山旱地种植的欧洲防风高产栽培技术。
1 适种区域
欧洲防风为耐寒性蔬菜,喜冷凉,抗旱能力强[1 ],对土壤的酸碱适应性较强,在天水市海拔2 000 m以下地区均可种植。
2 茬口选择
欧洲防风为伞形花科防风属作物,前茬以小麦、玉米、油菜等粮油作物及辣椒、白菜、黄瓜等蔬菜作物为好,忌与胡萝卜、芹菜等作物连作。
3 整地施肥
欧洲防风是以肥大的肉质根为产品的根菜类,适宜土壤深厚、排水良好、肥沃的砂质壤土。前茬作物收获后深耕、细耙,做到表土细碎、平整。……
