奥普尔在冬小麦上的应用效果研究

A Study on the Effect of OPAL in Winter Wheat

对冬小麦施用奥普尔液肥进行试验,结果表明:奥普尔(OPAL) 能促进小麦的生长发育,增加分蘖和干物质积累。返青期施用奥普尔可增强小麦抗倒伏能力;灌浆期施用奥普尔可促进小麦籽粒灌浆,提高穗粒数,增加穗粒重。不同奥普尔施用方法均有一定的增产作用,增产幅度2-85% ～17 .29 % 。奥普尔在播前土施待返青期和灌浆期喷施效果最好,与对照相比每公倾增产833 .0 kg,增收784 .5 元。

In this study,“OPAL”liquid fertilizer was applied to winter wheat.The result of the experiment showed that,this fertilizer could promote wheat growth,increase tiller and accumulation of dry matter.OPAL fertilizer,sprayed during the returning to green stage,can improve wheat lodging resistance.OPAL applications during filling stage,not only increase the grain number per spike but also increase the grain weight.A better effect that yield and profit was increased by 833.0 kg and 784.5 yuan per hm\+2 respectively can be obtained under the combinded OPAL application during pre seeding,returning to green stage and filling stage.\;
