钼肥施用模式对花生农艺性状、产量及蛋白质的影响

为探求钼肥对花生的作用与肥效。试验设置在河南省原阳县格林湾村进行,在施等量氧、磷、钾肥基础上设了3个处理,重复3次:(1)水浸花生种12 h为对照(CK);(2)0.1%钼肥浸花生种12 h;(3)0.1%钼肥浸花生种12 h后待花生五叶期和初花期各喷一次0.1%钼肥液。收获时测定花生产量与分析不同处理花生仁蛋白质含量。试验结果表明:0.1%钼肥浸花生种能促进根瘤菌的繁殖和生长,显著增加花生单株生产率和双仁果;增产花生果23.24%,花生仁蛋白质的含量增加1.26个百分点。与水浸种相比,0.1%钼肥浸花生种加喷施2次处理,增产花生果47.51%,花生仁蛋白质含量增加2.39个百分点达到极显著水平。由此认为:浸种加喷施处理效果最佳,具有很好的推广应用前景。

Effects of Molybdenum Fertilizer Appling Patterns on Agronomic Traits, Yield and Protein of Peanut

A fidld experiment was carried to study the influences of appling patterns of molybdenum fertilizer on agronomic traits,pod yield and protein of peanut in yuanyang county defiency molybdenum soil.The results showed that,peanut seed soaked 12 hours by 0.1%ammonium molybdate and spraying ammonium molybdate in early growth of peanut,pod yield increased by 47.5%,content of profein increased by 2.39percent point compare with soaked by water;peanut soakde seed 12 hours by 0.1% am-monium molybdte,pod yield increased by 23.24%,content of piotein increaode by 1.26 percent point compare with soaked by water;spraying ammonium molybdate two times,pod yield increased by 19.69%.In conclusion,under this experiment conditiom,the treatment of soaking seed and spraying by 0.1% ammonium molybdate was the best,and it has better extension appliance prospect
