摘要:在甘肃省旱作区进行适宜宽幅精准匀播栽培的冬小麦品种筛选试验。结果表明,临旱9号长势整齐,抗逆性好,折合产量6 222.0 kg/hm2,较对照品种长6878增产497.7 kg/hm2,增产率8.7%,建议在大田生产中示范推广;众信7298、长5553长势整齐折合产量均为5 973.1 kg/hm2,较对照品种长6878增产4.3%,在生产中可小面积示范。

Abstract:Taking the wild Lycium ruthenicum from Minqin of Gansu Province as the material, the nutrient contents of water, ash, fat, protein, total axunge, total flavonoids, polyphenol, total anthocyanins and amino acid were determined. The results showed that the cotent of wate was 795 g/kg, ash was 57.254 g/g, was fat 0.490 g/kg, protein was 0.084 83 g/kg, total flavonoids was 25.90 mg/g, total polyphenol was 27.51 mg/g, total anthocyanin was 1.27 mg/g. The total amino acids were 21.33 mg/g, among which seven kinds of essential amino acids accounted for 27.1% of the total amino acids. There were 9 kinds of pharmacodynamic amino acids, accounting for 65.8% of the total amino acids. The content of glutamic acid, aspartic acid and arginine in the pharmacodynamic amino acid is higher, which has higher medicinal value.

莊浪县位于甘肃省东部六盘山西麓,海拔1 405~2 857 m,属黄土高原丘陵沟壑区,年平均气温8.1 ℃,年降水量514 mm,≥10 ℃的活动积温2 208.8~2 903.7 ℃,无霜期145 d,属中温带干旱半干旱气候类型,是典型的旱作农业区。全县耕地面积6.11万hm2,种植作物以小麦、玉米和马铃薯为主,其中小麦种植面积1.73万hm2左右,种植模式由露地条播逐步转变为宽幅匀播[1 - 6 ]。针对目前粮食种植效益低,对小麦种植重视程度不够,小麦品种混、杂、乱等现象,我们引进了部分抗旱、抗病、抗逆性强的冬小麦新品种,在宽幅匀播栽培条件下进行了试验,以期为大田生产提供参考。
