摘要

本試驗以每公頃施用(A)雞糞堆肥7,500 kg、(B)含木黴菌雞糞之生物性堆肥7,500 kg、(C)化學肥料(N 80kg٫ P2O5 20 kg٫ K2O 120 Kg)、(D) AR3-2S土壤添加物2,400 kg (N 3.9%，P2O5 2.23%，K2O 1.71%)及無肥對照區(CK)等五種處理參試，所用資材、土壤及水質的重金屬均控制在標準值之下，進行有機與化學肥料對苧麻根產量的影響，結果發現平均每公頃苧麻根之鮮重及乾重分別為A處理14,389 kg及5,568.5 kg；D處理16,486 kg及6,871 kg；C處理11,375 kg及4,449.8 kg；而B及CK處理均較低，分別各為10,056 kg及4,082.7 kg與8,597 kg及3,430.2 kg，但經綜合變方分析結果顯示，處理間均未達5%顯著差異水準◦分析各處理苧麻根之總三萜及總酚類含量變化發現，總三萜含量以A處理之雞糞堆肥區的0.38%最高，其次為B處理之木黴菌堆肥區0.237%次之，分別對其餘三處理達5%顯著差異水準；總酚類含量以不施肥區（對照組）為0.148%最高，含量稍高於施用含木黴菌生物性堆肥區（B處理）及雞糞堆肥區（B處理），且顯著高於C及D處理，達5%顯著差異水準◦

The purpose of this study was to establish a model of good agricultural practices suitable for cultivation of Boehmeria nivesa in the field. The effects of different types of organic and chemical fertilizers on the root yield and active ingredients of this medicinal herb crop were evaluated. The concentrations of heavy metals and mineral elements in the tested organic and chemical fertilizers, and irrigation water were measured before planting. The control measures other than synthetic pesticides were used to manage the diseases and insect pests during plant growth stage. The treatments consisted of (A) chicken manure at 7,500 kg ha^(-1); (B) chicken manure with Tricoderma sp. at 7,500 kg ha^(-1); (C) chemical fertilizer at the rate of N:P2O5:K2O = 80: 20: 120 kg ha^(-1); (D) soil amendment (AR3-2S) with chemical fertilizer (N: P2O5: K2O = 3.9: 2.23: 1.71) at 2400 kg ha^(-1)and (E) non-treated plot used as the control (CK). Each treatment had four replicates in a randomized complete block design (RCBD). The results showed that there were no significant differences in root yield among treatments. The fresh and dry weight of root of B. nivesa were 14,389 kg and 5,568.5 kg in treatment A, 10,056 kg and 4,082.7 kg in treatment B, 11,375 kg and 4,449.8 kg in treatment C, 16,486 kg and 6,871.4 kg in treatment D, and 8,597 kg and 3,430.2 kg in CK, respectively. The triterpenes contents in roots harvested from treatment A and B were 0.38% and 0.237%, respectively, which were significantly (p=0.05) higher than other treatments. The content of total phenolic compounds in roots harvested from CK treatment was 0.148%, which was slight higher than A and B treatments, and significantly (p=0.05) higher than C and D treatments.
