摘要： 针对生物性状与产量的关系问题，研究了在八大类函数关系下，按照拟合优度、误差均方根、误差平方和等指标，选取最优的生物性状与产量的关系。结果表明，株高与大豆产量的函数关系为Fourier1，检验结果拟合优度、误差均方根和误差平方和分别为0.9228、6.836和93.45。叶面积指数与大豆产量的函数关系为Poly4，检验结果拟合优度、误差均方根和误差平方和分别为0.7362、71.87和319.2。试验结果表明当株高在46~50 cm范围内，产量关系先高后低，在大于51 cm范围，产量均很低。叶面积指数与大豆产量的关系成抛物线右侧状，随着大豆叶面积指数的增大，大豆产量先增加后降低。

Abstract: To explore the relationship between biological characters and soybean yield, this paper focused on selecting optimal function relationship between biological characters and soybean yield from eight types of functions by goodness of fitness (R2), root mean square error (RMSE), sum of squares due to error (SSE). The experimental results showed that the function relationship between height and soybean yield was Fourier1, and R2, RMSE, SSE was 0.9228, 6.836 and 93.45, respectively. On the other hand, the function relationship between index of leaf area and soybean yield was Poly4, and R2, RMSE, SSE was 0.7362, 71.87 and 319.2, respectively. In addition, the soybean yield changed from high to low when the plant height was in the range of 46-50 cm, and the yield was low when the plant height was more than 51 cm; the relationship between index of leaf area and soybean yield presented the right of parabola and soybean yield first increased and then decreased with the increase of index of leaf area.
