冬小麦施用沼肥增产效果试验研究

Effect of Biogas Fertilizer on Winter Wheat Yield

随着耕地面积的减少,提高小麦单产成为保障粮食安全的重要措施。天水市小麦面积占粮田面积的42%,产量占粮食总产的27.5%,产量低是制约小麦生产的关键因素。沼肥在小麦生产上的应用,对提高产量有很大的促进作用。为了进一步试验研究其增产作用,笔者设置了冬小麦施用沼肥增产效果试验,试验表明,基施沼肥并叶面喷施沼液的处理小麦生长健壮、生长发育快、产量性状好,增产幅度大,较基施农家肥未喷沼液处理株高、单株分蘖和单株次生根分别高1.7 cm,1.1个,3.8条,穗长、亩穗数、穗粒数、千粒重分别高0.5 cm,1.3万穗,1.9粒,1.0 g,亩增产15.7%。

Effect of biogas fertilizer on winter wheat was tested. The result showed that the base fertilizing with digestate and leaf spraying with biogas slurry could make the wheat grow stronger,faster,higher yield. The yield increased by15. 7% comparing with the basal fertilizing with farmyard manure.
