玉米栽培施用沼渣沼液的肥效试验

The experiment of fertilizer effect of biogas manure in growing corn

为了搞好沼气的开发和综合利用,利用沼渣、沼液作为肥料进行了玉米栽培试验。结果表明,施用沼渣、沼液表现出良好的肥效应,有利于提高玉米产量和促进生态农业的发展。其肥效应主要表现在:前期生长旺盛,出苗快而整齐,茎秆粗壮,叶片宽大,叶色浓绿,后期生长稳健,果穗大,穗行数增多,单穗实粒数增多,产量提高。其中施用沼渣、沼液的A处理产量最高,达到576 5kg·667m-2,与对照C、D处理相比,增产幅度达到21 13%和12 44%,经方差分析达极显著和显著水平。

The biogas manure was studied as fertilizer in corn cultivation.The result of experiment shows that the biogas manure has good ferilizer effect,can increase the output of corn.The young seedlings go out quickly and uniformly,grow flush during early stage,stems are strong,the width of leaves large and the color of leaves green.The spikes are big,the lines of spikes and the yields increase.The output reaches 576.5kg·667m^(-2) in A treatment with biogas manure.As compared with contrast treatment C and D,the yield of A treatment increases by 21.13% and 12.44% respectively.(According) to the analysis of variance,the differences are significant or very significant level.
