本文探讨了白芦笋种植密度对产量的影响。在株距０．３３ｍ情况下，行距１．３ｍ、１．５ｍ、１．７ｍ３年总产量显著高于行距１．９ｍ的对照，并以行距１．３ｍ的的总产量和一、二级品产量为最高；在行距１．５ｍ情况下，株距０．３０ｍ、０．３５ｍ比株距０．４０ｍ（对照）的产量增加，但差异不显著。在行距１．５ｍ、株距０．３３ｍ情况下，双行种植比单行种植产量也有提高趋势，但随着种植年限的延长，增加幅度逐年减少。适当密植能提高产量的基本原因在于株高和分枝数的增加。
This article discusses the white asparagus planting density on the yield. Under the condition of 0.33m plant spacing, the annual output of 1.3m, 1.5m and 1.7m3 was higher than the control of 1.9m of draft, and the total output of 1.3m and the output of primary and secondary products And the highest was 0.15 m. The row spacing was 0.30 m and 0.35 m was higher than the 0.40 m spacing (control). However, the difference was not significant. Under the circumstance of 1.5m row spacing and 0.33m spacing, the yield of double row planting also increased compared with that of single row, but with the extension of planting years, the increase range decreased year by year. The basic reason why proper planting can increase yield lies in the increase of plant height and branch number.
