黄淮平原大豆品质的气象条件

STUDIES ON THE METEOROLOGICAL CONDITIONS OF THE SEED QUALITY OF SOYBEANS IN HUANG HUAI PLAIN

采用几种数理统计方法,据黄淮海南一组5年夏大豆品种区域试验测定的蛋白质和脂肪含量资料与平行观测的气象资料,对黄淮平原大豆品质与气象条件关系进行分析,得出了形成蛋白质和脂肪所要求的气象条件是相异的分析结果.影响蛋白质形成的综合气候关键期是8月中旬,主导气象因子是温度;8月上旬是影响脂肪含量的综合气候关键期,主导因子是日照时数.温度日较差对二者均有重要影响.并找出影响蛋白质和脂肪含量的气象指标.

Many mathematic statistical methods were used for analyzing the relationship between meteorological factors and the content of seed protein or oil, on summer soybean varieties in the southern 1st group of Huang Huai Hai regional test (1985-1989). The result indicated that: the formation of seed protein were reqired different meteorological-factors from seed oil. The second decade in August was the complex key-climatic stage which had influence on the formation of protein and its major meteorological factor was temperature. The first decade in August was the complex key-climatic stage which had influence on the content of seed oil and its major factor was the sunshine-hours. The temperature range in each day had mainly influenced on the formation both of seed protein and seed oil. And found out such meteorological indexes that influenced on the formation of protein and oil.
