摘要 为探究适合菜心种植的自制水果酵素浓度,以常规施肥为对照,设置5个酵素浓度梯度,以及1个酵素浓度与3个肥料梯度组合处理。结果表明,稀释20倍、50倍的酵素浓度处理,菜心各生长指标与对照无显著差异,且较对照分别增产1.81%和8.32%;3个组合处理的菜心生长指标与对照无显著差异,但产量较对照减产6.30%~19.50%。

Abstract To explore the enzyme concentration of homemade fruit suitable for Chinese flowering cabbage,with conventional fertilization as a control,five enzyme concentration gradients and a combination of one enzyme concentration and three fertilizer gradients were set.The results showed that there was no significant difference in the growth indexes of Chinese flowering cabbage treated with 20 times and 50 times of enzyme concentration,and the yield increased by 1.81% and 8.32% compared with the control,respectively.There was no significant difference in the growth indexes of Chinese flowering cabbage treated with three combinations,but the yield decreased by 6.30%-19.50% compared with the control.
Key words Fruit enzyme;Chinese flowering cabbage;Growth index;Increase yield

2018年12月28日,中国工业和信息化部发布了关于酵素的2项标准,分别为 QB/T 5323—2018《植物酵素》和 QB/T 5324—2018《酵素产品分类导则》,标准中规定了农用植物酵素是以植物为主要原料经自然发酵或直接投入乳酸菌、醋酸菌及酵母菌进行人工发酵的微生物制剂。发酵后液体含有营养成分、代谢活性物质与有益微生物群,是具有多元复合功能的生态产品,目前作为叶面肥、滴灌肥、生物农药和分解菌剂等应用于农业生产,具有增产、抑菌、降解作物农药残留、修复土壤生化特性、调节水质、吸附及去除土壤重金属等作用。该技术是富集本地有益微生物和处理当地有机废弃物的一项简单易行的方法,具有成本低、设备简易和操作方便等优势,在生态文明的大背景下,具有广阔的研究和应用前景[1]。
