酵素营养液对小麦草营养成分的影响

Effect of Enzyme Solution on the Nutrient Composition of Wheat Straw

[目的]探究酵素营养液对提高小麦草作为优质动物饲料营养成分和营养价值的作用。[方法]选取1种小麦草种子进行萌发,之后开展为期8~10 d的水培试验,定期喷洒酵素营养液（酵素组）,对比不施任何营养液的小麦草（对照组）,分别测定其叶绿素含量、含水量以及单位质量干品所含的营养成分,即粗蛋白、粗脂肪、粗纤维、粗灰分、无氮浸出物。[结果]酵素组小麦草的粗蛋白、粗灰分含量显著高于对照组;后者的无氮浸出物显著高于前者,均高于60%。[结论]叶面喷洒酵素营养液能显著提高小麦草的营养成分,有效提高其作为动物饲料的综合品质。

[Objective]To study the effect of enzyme solution on nutritional composition and nutritional value of wheat straw as a high quality feed. [Method]The wheat straw seed were cultivated for 8 ~ 10 days after germination,with periodic spraying enzyme solution（ enzyme）,in contrast with the application of no nutritional wheat straw（ CK）,then measured the chlorophyll content,water content and nutrients contained in the product（ crude protein,crude fat,crude fiber,crude ash,nitrogen free extract）. [Result]The results showed that spraying enzyme solution could significantly increase the content of crude protein and ash in wheat straw,nitrogen free extract of the latter was significantly higher than that of the former,both higher than 60%. [Conclusion]Foliage-spraying enzyme solution can significantly improve the nutritional composition of wheat straw,and greatly improve the nutritional quality as feed.
