| 摘 要： | 以漯花4087为材料,设置7个播种密度,研究播种密度对花生农艺性状和产量的影响。结果表明:漯花4087的主茎高和侧枝长随着密度的加大均表现为先增加后降低的趋势;随着密度的增加,漯花4087的单株果数和饱果数不断减少,单株秕果数增加;百果重、百仁重、出仁率随着密度增加而降低;产量呈现出先增加后降低的趋势。密度为19.5万穴/公顷时漯花4087产量和经济效益最高。

| Abstract: | In order to study the appropriate planting density of peanut Luohua 4087,seven density treatments were designed for this experiment.The results showed that the main stem height and lateral branch length of Luohua 4087 increased first and then decreased with the density increasing.In addition,with the increase of density,Luohua 4087's fruit number per plant and full fruit number decreased continuously,and the number of dlighted fruit per plant increased with the increase of density.The weight of kernel weight and yield decreased with the increase of density.The yield showed a trend of increasing first and then decreasing.To sum up,under the conditions of this experiment,the yield and economic benefit of Luohua 4087 with a density of 195 000 holes/hm^2 were the highest. |
