摘要：

为筛选鲜食粒豌豆‘云豌18号’在滇中不同海拔区域的最佳种植密度，为良种配套良法提供依据，采用回归模型分析3个不同海拔试点不同种植密度对鲜食粒豌豆产量及构成因子的影响。结果表明，不同种植密度与产量拟合曲线均呈开口向下的二次抛物线关系，产量随种植密度的增加先呈上升趋势，当种植密度达一定量时产量达最高值，在一定种植密度范围内产量保持相对稳定，之后产量随种植密度增加而下降。3个海拔试点产量保持相对稳定的种植密度范围均为33万~42万株/hm2，海拔1545 m试点最佳种植密度为42万株/hm2，海拔1770 m试点最佳种植密度为33万株/hm2，海拔1970 m试点最佳种植密度为37.5万株/hm2。

Abstract:

To select the best planting density of fresh grain pea ‘Yunwan 18’ in different altitude areas of Yunnan, and provide a basis for good planting practices matching good varieties, the regression model was used to analyze the effects of different planting densities of three altitude areas on fresh grain pea yield and yield components. The results showed that the fitting curves of different planting densities and yield presented a quadratic parabola with the opening downward. The yield first increased with the increase of the planting density, reached the highest when the planting density was at a certain level and the yield remained relatively stable in a certain range of planting density. Then, the fresh grain pea yield decreased with the further increase of the planting density. The planting density for relatively stable yield in the three altitude areas was 330000-420000 plants/hm2. The optimum planting density at 1545 m altitude was 420000 plants/hm2, that at 1770 m was 330000 plants/hm2 and at 1970 m was 375000 plants/hm2.
