摘  要:
为探讨箭菩豌豆在西藏高海拔河谷地带的种子生产技术,选择333/A、西牧333、西牧881和西牧324等4个箭菩豌豆品种,在达孜县于2010年4月7日-5月6日分5个播种期进行了结实性比较试验.结果表明:333/A和西牧333在5个播期的种子产量平均为1746.18kg/hm^2和1873.00kg/hm^2,其中4月20日和4月28日播期的产量最高,2个品种均可达到2550kg/hm^2以上;西牧881和西牧324在5个播期的种子产量平均为493.44kg/hm^2和335.49kg/hm^2,最高产量仅能达到804.81kg/hm204个品种各播期种子产量与其千粒重的相关性分析表明,西牧324呈极显著正相关(P〈0.01),其他品种的相关性没有达到显著水平.333/A和西牧333各播期种子产量与秸秆产量均呈极显著负相关(P〈0.01).

摘  要:
In order to explore the seed production techniques of Vicia sativa in the high altitude valley area of Tibet, four varieties of Vicia sativa which were 333/A, Ximu 333, Ximu 881 and Ximu 324 were sowed in five different sowing dates from April 7 to May 6 in Dazi. The results showed that the average seed yields of 333/A and Ximu 333 were 1 746.18 kg/hm^2 and 1 873.00 kg/hm^2, the highest seed yield of these two varieties could reach more than 2 550 kg/hm^2 when sowed between April 20 and April 28, the average seed yields of Ximu 881 and Ximu 324 in five sowing date were 493.44 kg/hm^2 and 335.49 kg/hm^2,and the highest seed yield was only 804.81 kg/hm2.The correlation between seed yield and thousand grain weight of four varieties did not reach signifi- cant level except Ximu 324 (P〈 0.01 ), the correlation between seed yield and straw outputs were extremely significant negative correlation (/9〈 0.01 ) of 333/A and Ximu 333 in five different sowing dates.
