脱铬皮屑发酵液作为有机肥料的功效研究

Fertilizer Effect of Fermentation Broth of Dechromed Wet Blue Shavings as Organic Fertilizer

将脱铬皮屑发酵液用作苜蓿和小麦的浸种剂以及小麦水培营养液进行种子发芽试验和水培应用试验。浸种实验结果表明,脱铬皮屑发酵液质量浓度越高,苜蓿种子发芽率就越高,且最佳催芽质量浓度为80 mg/L,但对于小麦这种自身营养比较丰富的大种子,催芽效果并不明显。小麦苗水培试验结果表明,施加适量质量浓度的脱铬皮屑发酵液对小麦苗的生长具有明显的促进效果,可显著增加麦苗植株的高度和干湿重及水分含量、叶片的叶绿素和蛋白质含量,且最佳施肥质量浓度为100 mg/L。

The fermentation broth of dechromed wet blue shavings was used as a soaking agent for alfalfa and wheat and a nutrient solution for wheat hydroponics, respectively, for seed germination and hydroponic application tests. Results of the seed soaking experiments showed that the higher the concentration of the fermentation broth, the higher the germination rate of alfalfa seeds, and the optimal germination concentration was 80 mg/L. However, for the large seeds such as wheat,which are rich in nutrition, the germination effect of the fermentation broth was not obvious. Results of wheat seedling hydroponic experiments indicated that the optimum concentration(100 mg/L) of the fermentation broth of dechromed wet blue shavings had a significant effect on the growth of wheat seedlings. It could improve effectively the height, dry and wet weight and moisture content of the wheat seedlings, as well as the chlorophyll and protein content of the leaves.
