有机无机复混肥对冬小麦产量及其水分利用效率的影响

Effect of organic-inorganic fertilizers on the yield and water use efficiency of winter wheat

对农业废弃物采用生物发酵腐解,进行无害化、矿化和腐殖化处理,经干燥后添加一定比例的化肥以调节养分,加入成粒剂制成颗粒状有机无机复混肥。对获得的有机无机复混肥进行冬小麦田间试验,结果表明,有机无机复混肥可以促进冬小麦分蘖,改善冬小麦产量结构,提高冬小麦产量756.0～901.5kg/hm2;还可降低冬小麦耗水系数,提高冬小麦水分利用效率1.311～1.675kg/(mm·hm2)。

After the agricultural waste being decomposed by microorganism,it was harmless to environment.Then dried it and added certain chemistry fertilizers to adjust the nutrients,put in some granule-making agent,and made it into the granule of organic-inorganic fertilizer.The field experiments of applying it to winter wheat were carried out.The results showed that the organic-inorganic fertilizer could improve the tiller and the yield's composition of winter wheat,and increase the yield of winter wheat to (756.0)-901.5 kg/hm^2.It also could decrease the water consumption coefficient of winter wheat,and raise the water use efficiency of winter wheat to 1.311-1.657 kg/(mm·hm^2).
