施肥处理对茶叶产量、品质以及养分吸收的影响
Effects of Fertilization Treatments on Tea Yield and Quality and Nutrient Absorption
摘要
Abstract
The experiment took no fertilization as control,reducing chemical fertilizer,conventional fertilization,and combining organic fertilizer and chemical fertilizer as treatments,to explore the effects of different fertilization treatments on yield,quality and nutrient absorption in different seasons.The aim is to provide fertilization technical support for reducing chemical fertilizer in tea plantation soil,combining organic fertilizer,and improving tea quality.The results showed that the yield of tea with the reduced chemical fertilizer treatment(T1)was significantly higher than that of other treatments,T1 and T3 treatments could increase the content of organic carbon and total nitrogen in new shoots and mature leaves of tea trees,and reduce the C/N ratio of new shoots and mature leaves of tea trees.Compared with the control,T1 treatment could increase the amino acid content and reduce the tea polyphenols content of new shoots of tea trees,and both of the amino acid content and the tea polyphenols content of T3 treatment have been increased,and there is a significant or extremely significant correlation between quality indexes and nutrient absorption,among which organic carbon(shoots)and total nitrogen(shoots)are significantly correlated with each indicator.The reduction of chemical fertilizer(T1)could significantly increase tea yield,and the reduction of chemical fertilizer(T1)and combining 70%of inorganic nitrogen fertilizer with 30%of organic nitrogen fertilizer(T2)were both beneficial to the improvement of tea quality.关键词
