水稻喷施不同元素叶面肥对产量的影响

摘要

叶面肥是营养元素施用于农作物叶片表面,通过叶片的吸收而发挥基本功能的一种肥料。本试验通过对水稻分别喷施复旦复农、大田园、农都乐三种叶面肥进行对比,试验结果表明：水稻喷施叶面肥可以增加水稻穗粒数,提高结实率和千粒重,并且能降低病虫害的发病几率,从而达到增产增收目的。%Foliar fertilizer can display function by nutrient element which come from leaf surface. The test contrasted the foliar fertilizer among Fudanfunong, Datianynan and Nongdule, then the results indicated that foliar fertilizer can increase grains per spike, enhance setting rate and 1000-grain weight, reduce insect pests and therefore increased yield and increased income.
