摘要
铬革固体废弃物中含有80%以上的蛋白质,加工处理要比动植物废弃蛋白更加简单,通过脱铬、水解、螯合和过滤等过程,制成多元叶面肥的原液,并在油白菜上进行肥效试验。结果表明,铬革固体废弃物氨基酸多元叶面肥,能够从单株重、叶片数、叶绿素含量、VC含量和硝态氮含量等方面对油白菜生长进行影响,在提升产量的同时可以有效提高产品质量,其最佳喷施浓度为600~800倍稀释液。
The solid waste of chrome shavings had over 80% protein content, the process was easier than the waste of traditional animal and vegetable protein. Taking chrome leather solid waste as starting material, the target solution was got through chrome removal, hydrolysis, chelation, filtration etc. The agricultural chemical experiments proved that amino-acid chelated trace fertilizer had good effect on the weight of individual plant, number of leaves, the content of chlorophyll, vitamin C and Nitrate nitrogen during the whole growth stage. The effective concentration of dilute solution was between 6 hundred times and 8 hundred times.
