摘　　要：为促进黑龙江省芸豆高产栽培,通过研究5个不同种植密度对奶花芸豆产量的影响,筛选出黑龙江省北部地区奶花芸豆的最适种植密度,以期指导农业生产。结果表明:奶花芸豆密度在14.3万~22.3万株·hm^(-2)时,产量随着密度的增加而逐渐增加,密度为17.4万株·hm^(-2)时达到峰值,此时的产量最高,达到3 033.3kg·hm^(-2)。In order to promote high yield of light speckled kidney bean in Heilongjiang province and guide agri-cultural production,the effect of5different planting density on yield of light speckled kidney bean was studied,the optimum planting density of light speckled kidney bean in northern Heilongjiang province was screened.The results showed that when the planting density of light speckled kidney bean in1.43×105~2.23×105plant·hm2,the yield increased gradually,and reached the peak in the density of1.74×105plant·hm2,the yield was the highest,reaching3033.3kg·hm2.
