摘　　要：以垦丰11为试验材料,针对黑龙江省大豆生态区域特点,选择4个不同生态区的土壤在哈尔滨市进行盆栽试验,通过大棚和大棚中设立小棚实现高温和异常高温,研究大豆对高温胁迫的响应。结果表明：增加温度提高了大豆的植株高度;节数没有变化,平均节间距离加大,温度越高增加得越明显;大豆从出苗~鼓粒增加温度单株产量均下降;但是从出苗~开花高温百粒重增加,特别是异常高温百粒重增加得更明显。To investigate the reactions of soybeans to high temperature stress,Kenfeng 11 was pot cultured in four different types of soil in Harbin according to the features of the ecological regions for soybean growth in Heilongjiang province.By way of setting up greenhouses with small greenhouses inside,a high temperature and abnormal high temperature were achieved so as to provide experiment condition for the investigation.The results showed as follows： The plant height was increased by increasing temperature;the distance between nodes enhanced with the increase of temperature,while no effects were found on node number;The yield per plant decreased with the increase of temperature from seedling stage to seed filling stage,but the weight of 100-seed increased from the stage of seedling to flowering.The increase was especially significant when under the condition of abnormal high temperature.
