本文利用山东省夏大豆联合区域试验资料(1978—1982),分别统计了六个品种的产量与各个生育阶段中平均气温、累积日照时数和累积降水量的二级偏相关系数,并进行了显著性测验。统计结果表明:跃进五号花期需要高温,鼓粒阶段需要多日照才有利于增产;烟黄一号、东懈一号需要凉爽的气候条件;丰收黄产量与苗期和鼓粒阶段的平均气温呈显著负相关,与鼓粒阶段的累积日照时数呈显著正相关。根据各地气候特征和夏大豆品种的气候特性,选择适宜品种并适时播种是提高夏大豆产量的重要措施。
In this paper, we used the experimental data of summer soybean in Shandong Province (1978-1982) to calculate the second-order partial correlation coefficients of the yield of six cultivars, the average temperature in each growing stage, the cumulative sunshine hours and the cumulative precipitation. Significance test. The statistic results show that the high temperature is needed in the flowering stage of Yuejin No.5 and the need of more sunshine in the stage of drumming is favorable for the increase of yield. The temperature of harvesting and seedling stage and the average temperature There was a significant negative correlation between them and the accumulated sunshine duration in drum stage. According to the climatic characteristics and the climate characteristics of summer soybean varieties, the selection of suitable varieties and timely sowing is an important measure to increase summer soybean yield.
