叶面喷施钛微肥对三七生长及药材质量的影响
Effect of Titanium Microfertilizer Spraying on Growth and Medicinal Material Quality of Panax notoginseng
摘要
Abstract
Objective:To investigate the effects of titanium microfertilizer spraying on the growth,saponin synthesis and heavy met-al content of Panax notoginseng,and to screen out the optimal application concentration.Methods:In this experiment,biannual Panax notoginseng of Lancang county,Pu'er city,Yunnan province was used as material,and the leaves were sprayed with different concentra-tions of titanium microfertilizer solution(0.04％,0.05％,0.07％,0.1％)to detect the growth index,saponin content and heavy metal content in the roots of Panax notoginseng.Results:The biomass accumulation of Panax notoginseng and plant height of Panax notogin-seng were significantly increased by applying 0.1％titanium microfertilizer.After spraying titanium microfertilizer with 0.07％to 0.1％,the saponins content in Panax notoginseng roots was significantly increased.The Cu absorption of Panax notoginseng by spraying 0.05％titanium microfertilizer was significantly decreased.Conclusion:Foliar application of titanium microfertilizer can promote the growth of Panax notoginseng,promote the synthesis of saponins and antagonize the accumulation of heavy metal Cu,and the appropriate concentration of titanium microfertilizer is 0.1％.This study provides basis for the application of titanium microfertilizer in cultivation of Panax notoginseng.关键词
