陇中旱作区板蓝根"3414"优化栽培施肥模式研究
Study on Optimized Cultivation and Fertilization Model of Radix Isatidis Based on'3414'Design in Dryland Areas of Central Gansu
摘要
Abstract
In order to explore the effects of optimized cultivation and fertilization models on the yield,quality,and economic benefits of Radix Isatidis in the dryland area of central Gansu,the'3414'experimental design was adopted,with nitrogen,phosphorus,and potassium as main effective factors to establish an optimal fertilization scheme.Results showed that fertilization models significantly affected key agronomic characters,yield,internal quality,and economic benefit.The limiting nutrient factors for yield and economic return followed the order N>P>K.Among all treatments,the highest average yield(10 765.41 kg/ha)was obtained with application rates of N 217.08 kg/ha,P2O5 119.87 kg/ha,and K2O 57.27 kg/ha-an increase of 55.3%compared to the control(no fertilizer).The same treatment also achieved the highest economic return,with a value output of 43 061.64 Yuan/ha and net income increase of 13 513.51 Yuan/ha compared to the control.Under optimized fertilization,the(R,S)-goitrin content of Radix Isatidis generally met or exceeded the standards of the Pharmacopoeia of the People's Republic of China.A ternary quadratic equation predicted that the maximum fertilization rate for highest yield(10 765.82 kg/ha)would be N 323.39 kg/ha,P2O5 115.77 kg/ha,and K2O 77.71 kg/ha.The optimal fertilization rate was N 239.96 kg/ha,P2O5 78.43 kg/ha,and K2O 44.58 kg/ha,yielding 10 388.07 kg/ha.It is recommended that this optimal fertilization model be adopted for standardized production of Radix Isatidis in central Gansu's dryland region.关键词
