钼酸铵施用方法对花生生长与产量的影响

Effects of Application Methods of Ammonium Molybdate on Growth and Yield of Peanut

河南省土壤全Mo含量低于全国平均水平,有效Mo含量低于临界值（0.15 mg/kg）的土壤面积很大,贫Mo区（〈0.10 mg/kg）占全省土壤面积约4/5。Mo是植物必需营养元素,Mo肥施用在花生等豆科作物上,增产效果很显著,有试验表明,在缺Mo土壤上施用Mo肥,可增产花生荚果10%~46%。在原阳县秦庄村进行花生施用钼酸铵试验,结果表明,0.1%钼酸铵浸种加（团棵期与始花期）喷施2次处理比水浸种处理增产47.5%;喷施2次钼酸铵增产19.7%。表明钼酸铵浸种加喷施增产效果明显,生产上值得大面积推广应用。

Soil total molybdenum content of Henan province was below average value of China, area of soil effective molybdenum content under critical value（0.15 mg/kg） was very large, area of soil poor molybdenum（0.10 mg/kg） was about four- fifths.Molybdenum was one of plant essential nutrient element, Leguminous crops such as peanuts application molybdenum fertilizer, yield increased significantly; molybdenum fertilizer increased peanut pods by 10%- 46% in molybdenum deficiency soil arose from experiment results of our country. The experiment of peanuts application molybdenum fertilizer in Qinzhuang village, Yuanyang county was conducted, results showed that peanut seed soaked 12 hours by 0.1% ammonium molybdate and spraying ammonium molybdate in early growth of peanut, yield increased by 47.5% compare with soaked by water; spraying ammonium molybdate two times, yield increased by19.7%. The effect of increased yield by peanut seed soaked 12 hours by 0.1% ammonium molybdate and spraying ammonium molybdate was the best, which be worthy of widespread application.
