中文摘要	通过定位试验，探讨了黄土高原旱地不同播种期对豌豆产量的影响，供试材料为绿豌豆（高产品种）和热农2号（低产品种）。结果表明，不同播种期对高产豌豆品种出苗情况的影响大于对低产品种的影响。豌豆提前播种，可以增加低产品种的单位面积干物质积累量，但对高产品种的影响不显著。豌豆提前播种，可以提前达到盛花期，高产品种的盛花期早干低产品种的盛花期，在盛花期有较长时间避开六月份的高温天气，有利于高产。豌豆提前播种，可以增加高产品种的产量，显著增加低产品种的产量。有利于产量构成因素的形成，提高籽粒水分利用效率。
英文摘要	The effects of different sowing dates for two varieties of field pea have been examined through field site observations in an arid area of the Loess Plateau over two years. The experiment focused on two varieties of field pea, Green pea, which has high yield, and Yannong 2, which has low yield. The results showed that the effect of sowing date on plant numbers was greater for Green pea than for Yannong 2. However, early sowing could improve unit area dry matter accumulation of Yannong 2, this effect on Green pea is not significant. With early sowing peas reached full bloom earlier, full bloom of Green pea was earlier than Yannong 2, Yields could also be improved as plants had much time to establish pea grains before the high temperature weather came, This was particularly true for Green pea and produced a significant difference in the yield of Yannong 2. Early sowing was shown to positively affect node number per plant, pod number per plant, grain number per plant and grain weight, and improved pea grains water use efficiency.
