| 摘要: |
| 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756.0～901.5 kg/hm2;还可降低冬小麦耗水系数,提高冬小麦水分利用效率1.311～1.657 kg/(mm·hm2). |

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

| Abstract: |
| 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 granulemaking agent,and made it into the granule of organic-inorganic fertillzer.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/hm2.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·hm2). |
