摘要
以玉米品种冠玉598为试验材料,通过设置不同的沼液与化肥施肥配比,研究鹅粪沼液与化肥配施对土壤理化性状及青贮玉米生长、品质的影响。试验结果表明,施用沼液能够显著提高土壤有机质含量,且具有提高土壤硝态氮、速效磷、速效钾含量的趋势。施用沼液不会影响青贮玉米的出苗率,且能够显著降低幼苗虫害率。成熟期玉米鲜重以处理D:30%ZY+70%HF最高,分别比CK和处理A、B、C增加21.22%、14.30%、2.57%和14.30%。施用沼液能够显著降低玉米植株的粗灰分含量,显著提高其粗蛋白和粗脂肪含量;且能够显著提高玉米籽粒中淀粉含量。综合分析认为,按照30%沼液+70%化肥配施较适合青贮玉米的养分需求,产量最高,品质较优。
Using corn variety Guanyu 598 as experimental material, the effects of combined application of goose manure biogas slurry and chemical fertilizer on soil physicochemical properties, growth and quality of silage maize were studied by setting different ratio of biogas slurry and chemical fertilizer. The test results showed that the application of biogas slurry could significantly increase the content of soil organic matter, and had a tendency to increase the content of soil nitrate nitrogen, available phosphorus and available potassium. The application of biogas slurry did not affect the emergence rate of silage maize, and could significantly reduce the pest rate of seedlings. The fresh weight of maize in mature stage was the highest in treatment D: 30%ZY+70%HF, which increased by 21.22%, 14.30%, 2.57% and 14.30% compared with CK and treatments A, B and C, respectively. The application of biogas slurry could significantly reduce the ash content and increase the crude protein and ether extract content of maize plants. It could significantly increase the starch content in corn grains. According to the comprehensive analysis, the combined application of 30% biogas slurry and 70% chemical fertilizer is more suitable for the nutrient demand of silage maize, and the yield is the highest and the quality is better.
