中文摘要:
      为探明单粒精播模式下密度对不同类型花生产量及干物质积累的影响,以‘铁引花1 号’和‘唐A825’为试验材料,设置7.5 万穴/hm2、15 万穴/hm2、22.5 万穴/hm2、30 万穴/hm2、37.5 万穴/hm2、18 万穴/hm2(对照)6 个种植密度。结果表明:单播条件下适当密植有利用花生产量的提高,大粒型‘铁引花1 号’在15 万株/hm2时产量最佳,比对照增产15.8%。中小粒型‘唐A825’在22.5 万株/hm2时产量最佳,比对照增产26.5%。生育前期密度对植株各器官干物质积累影响不明显,生育后期群体产量、最大阶段积累量、最大日积累量、叶、茎、柄的干物质积累量等随种植密度的增加呈峰值变化,单株的干物质积累量、输出率、贡献率等均随种植密度的增加显著减少。
英文摘要:
      To find the effect of planting density on peanut yield and dry matter accumulation with single-seed precision sowing mode,‘Tieyinghua 1’and‘TangA825’were used as research materials. 6 planting densities of 7.5×104, 15×104, 22.5×104, 30×104, 37.5×104 and 18×104 plants/hm2 were set up. The results showed that proper increase of planting density under single-seed precision sowing was good for peanut production. The large-seed type‘Tieyinghua 1’had the best yield at 15×104 plants/hm2, 15.8% more than that of the control. The medium and small-seed type‘TangA825’had the best yield at 22.5×104 plants/hm2, 26.5% more than that of the control. Planting density did not have obvious influence on the dry matter accumulation at the earlier stage, and at the later stage, the group yields, the maximum stage accumulation, the maximum daily accumulation, the dry matter accumulation of leaves, stems and stalks had a peak change with the increase of planting density, while the dry matter accumulation, output rate, contribution rate of single plant decreased significantly with the increase of planting density.
