在黑龙江省18个地区选择熟期适宜的18份大豆品种为材料,结合当地8个主要环境因素数据,利用偏最小二乘多元回归方法对影响大豆品质的环境因素进行了分析。结果表明:蛋白质含量与经度、纬度、海拔、年平均气温、无霜期负相关,与年日照时数、降水量正相关。油分含量与经度、纬度、海拔、年平均气温、无霜期正相关,与年日照时数、降水量负相关。经度、纬度、海拔、年平均气温、无霜期等环境指标的提高对蛋白质含量形成和提高不利,却对油分含量的形成和提高有利;年日照时数、积温、降水量等环境指标的提高对蛋白质含量形成和提高有利,却不利于油分含量的形成和提高。这样的结论表明同一环境因素对蛋白质和油分形成可能具有互逆作用。
In this study, 18 soybean cultivars with suitable maturity were selected from 18 areas in Heilongjiang Province. Based on the data of 8 major environmental factors in the region, the environmental factors influencing soybean quality were analyzed by using PLSIM. The results showed that protein content was negatively correlated with longitude, latitude, altitude, annual mean temperature and frost-free period, and was positively correlated with annual sunshine hours and precipitation. Oil content and longitude, latitude, elevation, annual average temperature, frost-free period is positively correlated with the annual sunshine hours, precipitation is negatively correlated. Environmental indicators such as longitude, latitude, altitude, annual average temperature, frost-free period and other environmental indicators are unfavorable to the formation and improvement of protein content, but are beneficial to the formation and improvement of oil content. The increase of environmental indicators such as annual sunshine hours, accumulated temperature and precipitation, The formation of content and improve the favorable, but not conducive to the formation and increase of oil content. This conclusion suggests that the same environmental factors may have a reversal effect on the formation of protein and oil.
