叶面喷施微肥对川白芷主要有效成分含量的影响
Effects of micro-fertilizers foliar spray on the content of main effective components of Angelica dahurica
摘要
Abstract
The zinc,boron and molybdenum were sprayed on the foliage of Angelica dahurica du ring the vigorous growth period to explore the effects of the combination of zinc,boron and molybdenum fertilizers on the content of main effective components of A.dahurica,and to find out the optimum spraying amount.The results showed that the application of zinc,boron and molybdenum foliar spray was beneficial to increase the content of imperatorin and total cumarin,whereas had no effect on the content of the isoimperatorin.The effect of boron spray on the accumulation of imperatorin and total coumarin was the most significant,followed by the zinc and molybdenum.The interaction between boron and molybdenum had a negative cooperative effect on the content of imperatorin,while the interaction between zinc and molybdenum had a positive cooperative effect on the content of total coumarin.The contents of total coumarin reached over 0.7％ respectively,with the complex fertilizer spray of zinc at 0.15-0.24 kg · hm-2,boron at 2.02-2.36 kg · hm-2 and molybdenum at 0.08-0.13 kg · hm-2.The contents of imperatorin reached over 0.2％ respectively,with the complex fertilizer spray of zinc at 0.15-0.20 kg · hm-2,boron at 1.37-1.47 kg · hm-2 and molybdenum at 0.09-0.13 kg · hm-2.It was concluded that the application of zinc,boron and molybdenum foliar spray was beneficial to promote the quality of A.dahurica by enhancing its accumulation of coumarin.关键词
