摘    要:目的]研究沼液在农业生产中的应用效果。方法]以复合肥和普通农家肥为对照,设不同浓度的沼液处理。采用不同浓度沼液对西兰花、冰糖橙、香蕉3种作物进行追肥,通过田间试验,分别测定西兰花、冰糖橙、香蕉的产量、Vc含量和含糖量。结果]用沼液进行追肥,可以增加西兰花、香蕉、冰糖橙的产量和Vc含量,增产率最高分别达111.90%、100.80%、132.40%,Vc含量的增加率最高分别达45.33%、33.13%、14.13%;香蕉和冰糖橙的还原糖含量增加率最高分别达407.56%和18.07%;沼液对3种作物的含糖量也有一定的影响,其中西兰花含糖量随沼液浓度的增大而减少,还原糖含量最大降幅达10.15%,总糖含量最大降幅达37.13%。结论]综合分析,沼液在作物种植中有较大的推广应用价值。

关 键 词:沼液  产量  Vc  含糖量

Application Effect of Biogas Slurry in Planting of Broccoli,Sweet Orange and Banana
Abstract:Objective] To study the application effect of biogas slurry in agricultural production . Method] Compound fertilizer and common farm manure were compared with different concentrations of biogas slurry.Different concentrations of biogas slurry were applied in planting of broccoli, sweet orange and banana, and the yield, vitamin C and sugar content of the three kinds of crops were analyzed through field test. Result] The yield and vitamin C content of broccoli, sweet orange and banana were increased by the application of biogas slurry, and the highest increasing rate of the yield was up to 111.9%, 100.8%, and 132.4% respectively, while the highest increasing rate of vitamin C content reached 45.33%, 33.13%, and 14.13% respectively.The reducing sugar content of banana and sweet orange were also improved, and the increasing rate was up to 407.56% and 18.07% respectively.Sugar content of the three kinds of crops was also influenced by the ap-plication of biogas slurry.The sugar content of broccoli decreased with the increase of biogas slurry concentration, and the biggest drop of re-ducing sugarand total sugar content reached 10.15% and 37.13% respectively.Conclusion] Biogas slurry has great popularization and ap-plication valuein planting of crops.
Keywords:Biogas slurry  Yield  Vitamin C  Sugar content
