摘要
通过田间试验研究不同控释肥对芦笋产量、品质及养分含量的影响。结果表明,施用控释肥的整体效果要优于习惯施肥。施用控释肥能够提高芦笋产量、提升芦笋品质、提高芦笋中的养分含量。通过控释肥之间的比较,控释肥Ⅰ在提高产量和维生素C含量方面最为显著,分别比习惯施肥处理增加2.79%和17.65%;控释肥Ⅱ在提高可溶性总糖含量、降低硝酸盐含量方面效果显著,提高、降低的幅度分别达到3.37%、56.87%;控释肥Ⅲ则可使芦笋对养分的吸收利用更加完全。
The effects of different controlled-release fertilizers on Asparagus officinalisL.＇s yield,quality and nutrient contents were studied by field experiment.The results showed that the controlled-released fertilizers were superior to the conventional fertilizer.To a certain extent,the controlled-released fertilizers could increase the yield,quality and nutrient contents of Asparagus officinalisL.The yield and VC content of Asparagus officinalisL.treated by controlled-released fertilizerⅠwere increased by 2.79% and 17.65%,respectively.The controlled-released fertilizer Ⅱ could increase the total soluble sugar by 3.37% and decrease the nutrient content by 56.87%.The controlled-released fertilizer Ⅲ could make Asparagus officinalisL.to absorb nutrient more completely.
