摘　　要：为探索花生适宜种植方式及单粒精播密度,选取泉花22号为试验材料,采用裂区设计,以裸地和覆地膜两种种植方式为主处理,单粒播种5种密度为副处理,分别以双粒常规播种密度为对照,比较两种种植方式下不同播种密度植株生长和荚果产量差异情况。结果表明:覆地膜种植处理与裸地种植处理相比,可缩短生育期、提高产量,二者产量差异极显著。两组主处理内的副处理,均以株行距为17 cm×17 cm单粒播种密度处理的产量为最高;裸地种植方式该密度产量为3308.85 kg·hm^(-2),比组内对照增产13.30%,差异极显著;覆地膜种植方式该密度产量达3737.63 kg·hm^(-2),比组内对照增产8.34%,差异极显著。试验选用的泉花22号花生,采用株行距17 cm×17 cm单粒播种覆地膜种植,具有较好的增产增效潜力。In order to explore the suitable planting mode and single-seed precision sowing density of peanut,Quanhua No.22 was selected as the experimental material,and the split-plot design was adopted.The two planting methods of bare land and film mulching were the main treatments,and the five densities of single-seed sowing were the secondary treatments.The difference of plant growth and pod yield under two planting patterns with different seeding densities was compared with the double-seed conventional seeding density as comparison.The results showed that compared with the planting treatment of bare land,the planting treatment of film mulching could shorten the growth period and increase the yield,and the yield difference between them was extremely significant.The yields of peanut under the treatment of single-seed sowing density with the planting spacing of 17 cm×17 cm were all the highest in the secondary treatments of the two main treatments.The yield was 3308.85 kg·hm^(-2) under the treatment of bare land,which was 13.30%higher than that of the control group,and the difference was significant.The yield was 3737.63 kg·hm^(-2) under the treatment of film mulching,which was 8.34%higher than that of the control group,and the difference was extremely significant.The peanut variety Quanhua No.22 selected in the experiment was planted with the treatment of single-seed sowing and film mulching with the planting spacing of 17 cm×17 cm,which had good potential for increasing the yield and efficiency.
