摘要
为了研究播种密度对辣椒产量的影响,对辣椒优质高产栽培技术提供理论依据,进行了辣椒不同播种密度试验。结果表明,随着播种密度的增加,辣椒发芽率呈增加趋势;当播种密度大于1 100粒/m2时,辣椒发芽率趋于平稳,但产量下降;当密度小于1 100粒/m2时,随着播种密度的减少,辣椒发芽率降低,产量也呈下降趋势。说明,播种密度为1 100粒/m2时,辣椒的生长发育农艺性状及产量比较理想。
A hot pepper variety was tested under different sowing density to study the effect of different sowing density on its yield for providing the theoretical basis in cultivation of hot peppers with quality and high-yield. The results showed that the germination rate rose with increase of sowing density, when the sowing density was over 1100 seeds/m^2 the germination rate was stable and the yield dropped, when the sowing density was below 1 100 seeds/m^2 the germination rate and yield reduced with decrease of sowing density. The optimum sowing density for its better growth, development and yield is 1 100 seeds/m^2.
