Abstract：Using Zhoumai 22 as the experimental material,a field experiment was conducted to investigate the effects of different organic materials[straw(S),chicken manure(M),mushroom residue(MR)and biochar(B)]on the contents of total starch,amylose,amylopectin,total protein,glutenin,prolamin,albumin,globulin,phosphorus(P),potassium(K),calcium(Ca),iron(Fe)and zinc(Zn)of winter wheat grain under different irrigation regimes[full irrigation(FI,45 mm per irrigation)and deficit irrigation(DI,33.75 mm per irrigation)],so as to provide theoretical and technical support for water-saving and high-quality winter wheat production.The results showed that,compared with full irrigation,under deficit irrigation condition,biochar treatment exhibited the best improvement effect on total starch content,amylopectin content,glutenin content and Fe content,with increases of 19.49%,23.55%,22.41%and 98.09%,respectively;mushroom residue treatment had the best enhancement effect on prolamin content,albumin content and globulin content,with increases of 17.20%,9.67%and 24.37%,respectively;chicken manure treatment had the best enhancement effect on total protein content,Zn content and Ca content,with increases of 5.80%,31.06%and 28.71%,respectively.Under deficit irrigation condition,compared with straw treatment,biochar treatment had the best enhancement effect on total starch content,amylopectin content and prolamin content,with increases of 15.83%,21.30%and 25.00%,respectively;mushroom residue treatment had the best enhancement effect on globulin content,with an increase of 30.20%;chicken manure treatment had the best enhancement effect on total protein content,glutenin content,albumin content and Fe content,with increases of 5.63%,10.39%,18.11%and 72.90%,respectively.Under full irrigation condition,compared with straw treatment,biochar treatment had the best enhancement effect on prolamin content;chicken manure treatment had the best enhancement effect on total starch content,amylopectin content,total protein content,glutenin content,albumin content,globulin content and Fe content.Overall,under deficit irrigation condition,biochar and chicken manure have better effect,which can effectively modulate the biosynthesis and accumulation of starch,proteins and Fe in wheat grains,thereby substantially improving grain nutritional quality.
