N、P、K配方施肥对1年生黄芩生长的影响
Effects of Formula Fertilization of Nitrogen, Phosphorus and Potassium on the Growth of Annual RADIX SCUTELLARIAE
摘要
Abstract
[Objective] To study on the effects of formula fertilization of N, P and K on the growth of annual RADIX SCUTELLARIAE. [ Method ] Three factors secondary D-saturation optimal design was adopted to discuss on the effects of N, P and K ratios on RADIX SCUTELLARIAE growth. In general, formula fertilization of N, P and K was superior to the combination of two elements and only one element. The optimal fertilization condition was 79.41 kg/hm2 N, 150.00kg/hm2 P2O5, and 150.00 kg/hm2 K2O. Under this condition, content of poly-saccharides in RADIX SCUTELLARIAE was 7.4%. [Conclusion] The optimal fertilization method was selected, which provided references for the production of RADIX SCUTELLARIAE.关键词
