黄土高原半干旱山区箭舌豌豆品种比较研究

Study on variety comparison of Vicia sativa L. in semi arid areas in the Loess Plateau

箭舌豌豆是一种优良的饲料和绿肥兼用作物 ,在黄土高原干旱、半干旱山区广泛种植。对黄土高原半干旱山区普遍种植的 9个箭舌豌豆品种从青草产量、种子产量和生育期 3个主要指标进行了比较研究和统计分析。结果表明 ,箭舌豌豆 881和 3 2 4品种在青草和种子产量方面表现优良 ,分别达到 1 40 0 0 kg/hm2和 2 6 0 0 kg/hm2以上 ,宜作为该地区的推广品种种植 ,3 3 3 /A和 3 3 3等箭舌豌豆品种以其生育期短、成熟早而表现突出 ,分别为 1 1 1 d和 1 1 2 d,宜作为本地区的填闲、绿肥作物种植 。

Study and analysis has been made to 3 quotas of fresh forage yield, seed yield and growth stage of 9 selected vetch varieties widespreadly cultivated in semi arid areas in the Loess Plateau of China. The results show that the vetch varieties of 881 and 324 acquired higher yield on fresh forage and seed. It can be reached 14 000 kg/hm 2 and 2 600 kg/hm 2 separately. The 2 varieties can be spread in the semi arid areas of Loess Plateau. The varieties of 333/A and 333 have shorter growth stage, only 111 d and 112 d separately. It can be cultivated for alternate crop or green manure crop in semi arid areas, either can be cultivated in cooler areas.
