| 摘 要： | 本文对三个莴笋品种的播期与产量的关系,采用15种曲线进行拟合研究。分析结果表明它们的最佳拟合曲线皆为二次曲线,通过方程预测它们的最佳播期分别是8月19、18和16日,与之对应的平均单株最高产量分别为0.33,0.31和0.28kg。

| Abstract: | The relationship between the sowing period and yield of three asparagus lettuce varieties was studied by the coordination of fifteen curves. The analysed conclusion showed that their best mimic curves were all quadratic. It was fore casted through the equation that their best sowing periods are August 19, 18 and 16 respectively and the highest yields per plant are 0.38, 0.31 and 0.28kg in each variety. |
