摘要
为提高旱薄地花生产量、改善品质,缓解花生种植土壤缺钼情况,通过盆栽试验,设置0(CK)、0.5、1.0、1.5 g/kg 4个钼酸铵拌种量,分析钼酸铵拌种对花生生长发育及氮素积累的影响,探讨最佳钼酸铵拌种量。结果表明,钼酸铵拌种可促进花生营养生长和生殖生长,提高花生叶片面积和光合速率,提高器官含氮量及产量,改善花生品质。其中钼酸铵拌种量为1.0~1.5 g/kg效果最佳,与对照相比,钼酸铵拌种量1.5 g/kg处理单株开花数增加48.43朵,收获时果针数、荚果数、荚果体积提高19.46%、26.49%、16.39%,叶面积、叶片净光合速率分别增加25.20%、51.08%,单株生产力提高32.74%。可见,通过钼酸铵拌种能显著促进旱薄地花生营养生长和生殖生长,促进各器官氮素积累,提高花生产量,改善花生品质。
In order to improve the yield and quality of peanut in dry and thin land and alleviate the lack of molybdenum in peanut planting soil,pot experiments were conducted to set four ammonium molybdate seed dressing amounts of 0(CK),0.5,1.0 and 1.5 g/kg to analyze the effects of ammonium molybdate seed dressing on peanut growth and nitrogen accumulation,and to explore the optimal ammonium molybdate seed dressing amount.The results showed that the seed dressing with ammonium molybdate could promote the vegetative growth and reproductive growth of peanut,improve the leaf area and photosynthetic rate,increase the nitrogen content of organ and yield,and improve the quality of peanut.Among them,application of 1.0—1.5 g/kg ammonium molybdate had the best effect.Compared with the control group,application of 1.5 g/kg ammonium molybdate could increase the flower number,fruit number,pod number per plant and pod volume by 48.43,19.46%,26.49%and 16.39%,improve the leaf area,leaf net photosynthetic rate and productivity per plant by 25.20%,51.08%and 32.74%respectively.Tests had shown that the application of ammonium molybdate could significantly increase peanut vegetative and reproductive growth,promote nitrogen accumulation in various organs,increase peanut yield,and improve peanut quality.
