黑龙江省南部黑土不同施氮水平对大豆产量的影响
The effect of nitrogen rates on yield of soyean planted in Black soil of Heilongjiang Province
【摘要】 试验设 3个氮水平 ,测定了 3个大豆品种黑农 37、东农 4 2和 90 681各生育时期的干物质积累 ,以及子粒产量、百粒重。结果表明 ,不同品种大豆干物质积累有较大差别 ,并均随施氮水平的提高而增加。子粒产量也随施氮水平的提高而增加。但百粒重却无明显差异
【Abstract】 A pot experiment has been conducted to study on the yield of 3 soybean cultivars at 3 nitrogen rates. The results show that the accumulation of dry matter and seed yields all increase with nitrogen rates,but that the weight of 100 seeds increase little except that of Dongnong 42.$$$$
