摘要
为了研究不同种植密度对辣木生长量及产量的影响,在云南河口开展3种种植密度(80cm×150cm、150cm×200cm、250cm×300cm)对辣木生长量及产量的影响试验。结果表明种植密度250cm×300cm的地径增长量显著高于种植密度80cm×150cm的,3种密度株高增长量差异不显著;种植密度250cm×300cm的辣木开花和种子成熟期比密度80cm×150cm的提前20d左右;3种种植密度的结实率均较低,密度小的250cm×300cm的结实率和种子千粒重较大,即果实质量较高,但差异不显著。适当减小种植密度可促进辣木的生长及提高种子产量。
Moringa oleifera was planted at different densities(80 cm×150 cm,150 cm×200 cm,250 cm×300 cm)to observe the effect of planting density on the growth and yield of M.oleifera in Hekou,Yunnan.Results showed that M.oleifera planted at a density of 250 cm×300 cm gave a significantly higher basal diameter increment than that at a planting density of 80 cm×150 cm,and that M.oleifera planted at the 3 densities were not significantly different in plant height increment.The flowering stage and see maturity stage of the plants with a planting density of 250 cm×300 cm were about 20 days ahead of those with higher planting densities.All the plants at the three planting densities had lower fruit setting rate.The plants with small planting density of 250 cm×300 cm had a higher fruitsetting rate and 1 000 seeds weight,indicating a higher fruit quality but without significant difference.Reducing planting density can promote growth and increase seed yield of M.oleifera.
