黄土高原半干旱山区箭舌豌豆品种比较研究

摘要

Study and analysis has been made to 3 quotas of fresh forage yield, seed yield and growth stage of 9 selected vetch varieties widespreadly cu ltivated in semi-arid areas in the Loess Plateau of China. The results show that the vetch varieties of 88 1 and 324 acquired higher yield on fresh forage and seed. It can be reached 14 000 kg/hm2 and 2 600 kg/hm2 separately. The 2 varieties can be sprea d in the semi-arid areas of Loess Plateau. The varieties of 333/A and 333 have short er growth sta ge, 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.%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324品种在青草和种子产量方面表现优良，分别达到14000kg/hm2和2 600 kg/hm2以上，宜作为该地区的推广品种种植，333/A和333等箭舌豌豆品种以其生育期短、成熟早而表现突出，分别为111d和112d，宜作为本地区的填闲、绿肥作物种植，也可用于作物生长期短的冷凉地区推广。
