以葡萄、苹果、番茄等果渣类废弃物,树皮、树叶、杂草等植物类废弃物作为生化腐植酸(BHA)的制备原料,在不同菌种、不同发酵时间下进行固态发酵,合成几种含吲哚乙酸、脱落酸或赤霉素的高活性生化腐植酸。研究了这几种高活性生化腐植酸对α-淀粉酶、过氧化氢酶和植酸酶的活性及对植物种子萌芽的生长情况的影响。试验结果表明:生化腐植酸在浓度适宜的情况下对α-淀粉酶、过氧化氢酶和植酸酶的活性以及植物种子的生长有促进作用,但浓度过高时就出现抑制现象。本研究以廉价的原料制备高附加值的生化腐植酸,农业应用前景广阔。
Plant waste such as grapes, apples, tomatoes and other residues of wastes, bark, leaves, weeds and other plant wastes as biochemical humic acid (BHA) preparation of raw materials, in different strains, different fermentation time solid state fermentation, synthesis Several containing indole acetic acid, abscisic acid or gibberellin highly active biochemical humic acid. The effects of these highly active biochemical humic acids on the activity of α-amylase, catalase and phytase and the growth of plant seed germination were studied. The results showed that biochemical humic acid promoted the activity of α-amylase, catalase and phytase and the growth of plant seeds under the suitable concentration, but the inhibition occurred when the concentration was too high. In this study, high value-added biochemical humic acid was prepared from cheap raw materials, and the agricultural application had a bright future.
