通过对1994—2013年通化地区中熟大豆品种吉林20的多年定位种植,观测各个生育进程并进行考种、测产。将其数据与气象资料进行相关分析得出了一定结论:通过对年度间大豆产量性状的分析,不同年度间主茎节数、百粒重2项指标较为稳定,受年度间环境影响小,其次是株高、单株粒重、产量、荚数合计年度间差异较大。构成大豆产量的主要性状中粒数、荚数、分枝数、虫口率变异系数较大。说明本地区大豆生产受环境条件影响比较明显。对通化地区5—9月各月积温进行分析,得出在通化地区大豆产量与9月中旬的积温显著正相关,说明9月的高温与大豆产量显著正相关。在本地区大豆产量与9月中旬的积温显著相关,产量随积温升高而增加,符合直线方程y=20.730x-1 134.9的结论。
Through years of planting in Jilin 20, a middle-maturing soybean cultivar in Tonghua district from 1994 to 2013, we observed the progress of each fertility and tested the seed production. According to the correlation analysis between the data and meteorological data, some conclusions are drawn: According to the analysis of annual yield of soybean, the number of stems and the index of 100 kernel weight in different years are relatively stable, Is the plant height, grain weight per plant, yield, pods, the total annual differences between the larger. The main characters of soybean yield were the number of kernels, the number of pods, the number of branches and the coefficient of variation of insect population. This shows that the soybean production in the region is more affected by environmental conditions. The monthly temperature accumulated in May-September in Tonghua district was analyzed. It was concluded that the output of soybean in Tonghua district was positively correlated with the accumulated temperature in mid-September, indicating that there was a significant positive correlation between the high temperature in September and the soybean yield. Soybean production in the region was significantly correlated with accumulated temperature in mid-September, and the yield increased with increasing accumulated temperature, consistent with the linear equation y = 20.730x-1 134.9.
