Abstract:
Taking Isatis indigotica Fort. as test material，the ‘3414’ fertilizer experiment was conducted to study the effects on water-soluble nitrogen(N),phosphorus(P) and potassium(K) combined application on morphological index,yield and quality of Isatis indigotica Fort.and the comprehensive utilization value of each treatment was evaluated by grey relational degree method，in order to provide reference for the extensive application of water and fertilizer integration in Isatis indigotica Fort..The results showed that different fertilization treatments had significant effects on morphology index，leaf yield and root yield and economic benefit of Isatis indigotica Fort.(P<0.05).The leaf yield，root yield，and economic benefits of the 13 fertilization treatments were all superior to treatment 1 (N0P30K0).Treatment 7 had the best performance，and its leaf yield，root yield and economic benefit were 14 031.8 kg·hm-2，2 500.0 kg·hm-2 and 35 034.2 RMB·hm-2，which were 77.3%，41.9% and 31.3% higher than treatment 1，respectively.(R,S) -goitrin content in roots was 0.124 8%,much higher than treatment 1 (0.036 4%).It was suggested that the appropriate application rate of water-soluble fertilizer of Isatis indigotica Fort. in Longdong area was 4.2 kg·hm-2 for N，17.1 kg·hm-2 for P2O5 and 8.7 kg·hm-2 for K2O.
