不同中药渣对紫苏生长及酚类物质的影响

Effect of herb residues compost on growth and phenols of Perilla frutescens

中药渣营养成分丰富,是一种优质的有机肥原料,可以发酵成优质的有机肥,但是目前中药渣多数被当作生活垃圾处理,不仅占用了大量的土地资源,污染了环境,而且还造成资源的浪费。针对上述情况,该文采用盆栽的方法研究了不同中药渣对紫苏生长及有效成分的影响。研究结果表明不同种类的中药渣均能促进紫苏生长,其促进生长作用的大小顺序为丹参渣>麦芽渣>连翘渣>白术渣>丹皮渣、苦参渣,其中丹皮渣和苦参渣处理组与CK对照相比无显著性差异;不同种类的中药渣还能改善根系结构,增加叶片面积;同时不同种类的中药渣均能提高地下部分迷迭香酸和咖啡酸的含量,而对于地上部分4种酚类物质的积累量也具有提高的作用。综上所述,中药渣有机肥能够促进紫苏生长,提高紫苏酚类物质的积累量,其中丹参渣作用效果最好。

Herb residue is post-decoction material that can be used as organic fertilizer. Unfortunately,it is currently disposed of as solid waste. This method of disposal is a waste of this resource and a source of environmental pollution. For this case,we studied effects of six different herb residues compost on growth and phenols of Perilla frutescens by pot experiment. Our results show that all six herb residues can improve the growth of P. frutescens. The order of their efficiencies was as follows： Salviae Miltiorrhizae Radix residue 〉Hordei Fructus germinates residue 〉 Forsythia fructus residue 〉 Atractylodis Macrocephalae Rhizome residue 〉 Sophorae Flavescentis Redix residue and Moutan cortex residue. Effects of Sophorae Flavescentis Radix residue and Moutan Cortex residue weren’t significantly different from CK. Six herb residue all improve root system architecture and leaf area. To phenols of P. frutescens,six herb residues all increased the rosmarinic acid and caffeic acid content of root,and accumulation of four phenols. All the analysis showed herb residues compost can improve the growth and four phenols accumulation of P. frutescens,and Salviae Miltiorrhizae Radix residue had the most pronounced effect on P. frutescens
