花生在赤峰地区种植密度试验初探

The Experiment of Planting Density of Peanut in Chifeng

文章通过田间试验研究了花生在不同播种密度条件下的产量和个体经济性状表现,研究结果表明:随着花生播种密度的增加,产量也在逐渐增加,密度为31.5万株/hm2时单产达3.38t/hm2。但随着播种密度的增加,花生个体经济性状表现是先升高后降低,当密度为28.5万株/hm2时,个体经济性状表现达最高点。

Through the field cuhivation , different density experiment of peanut was carried out to provide effect on yield and individual economic character.The results showed that with the growth of peanut density,per hectare yield on peanut grew too. when the density was 315 thousand hole per hm2,the yield was 3.38t.But with the increases of the density,the individual economic character appeared increased first and decreased later,when the density was 285 thousand hole per hmE,the individual economic character increased to a peak.
