不同土壤肥力对当归品质和产量的影响
Influence of different soil fertility on yield and quality of angelica
摘要
Abstract
[Objective]The objective of present experiment was to study the relationship between soil fertility indices and yield and quality of angelica, and to provide the scientific basis for its Chinese crude drugs (GAP) cultivation. [Method ]The methods of correlation analysis and path analysis was used to study the major soil fertility affecting factors and their effects on yield and quality of angelica. [ Result ]The ferulic acid content of angelica was recorded in the range of 1.56-2.42 mg/g and yield of single plant angelica from 38.95-257.26 g in Yunnan area. The ferulic acid content and fresh weight per plant angelica were positively correlated with the N, K and organic matter contents, whereas a negative correlation of them was observed with P content The most important soil fertility factor influencing the angelica ferulic acid content was recorded as K, whereas the organic matter was found as least influencing factor. The most important soil fertility factor influencing the fresh weight per plant angelica was N, whereas the least influencing factor was P. [Conclusions]The results of the present study revealed that N and K may play an important role in enhancing yield and quality of angelica.关键词
