硒营养剂不同施用水平和施用方式对当归产量及品质的影响
Effects of different fertilization methods and levels of Se-neurotrophic agents on yield and main quality indexes of Angelica sinensis
摘要
Abstract
In order to investigate the effects of Se-neurotrophic agents on yield and main quality ndexes of Angelica sinensis ,a field experiment was designed by employing two fertilization levels (low and high fertilizations ) and three irri-gation methods (AF:all applied as basal fertilizer;HF:half applied as basal fertilizer and half applied as spraying fertil-izer;MF:2/3 applied as basal fertilizer and 1/3 applied as spraying fertilizer ) .The resulting yield and main quality in-dexes of Angelica sinensis were measured .The fertilizer application level of Se-neurotrophic agents significantly influ-enced the yield and main quality indexes of Angelica sinensis ,and the effects by high fertilization were more significant than those by low fertilization .Compared to the AF treatment ,under low and high fertilizations ,MF treatment increased the yield of Angelica sinensis by 9 .6% and 20% ,respectively .The highest yield by MF treatment was 2 208 .33 kg· hm-2 with high fertilization .Under high fertilization ,the maximal volatile oil ,ferulaic acid and extractives contents by AF treatment was 1 .0% ,0 .184% and 58 .6% ,which were 20 .5% ,35 .3% and 5 .6% higher than those by the HF treatment .In conclusion ,under high fertilization level (75 kg·hm-2 ) ,the MF treatment can help increase the yield of Angelica sinensis ,and the AF treatment may help increase the quality of Angelica sinensis .关键词
