摘要
从甘草栽培角度入手,分析不同施肥配比对甘草营养元素含量的影响,并根据不同需求,提出相应的最佳施肥配比方案。以对甘草全K含量预测控制模型参数估计为结果,建议栽培甘草施肥时,增施P肥,减少K肥施用量。此结果为今后该地区甘草营养元素研究提供了基础资料,同时为甘草在该地区的栽培与保护提供了科学依据。
This article obtains from the perspective of licorice cultivation,analyzes the influence of different fertilizer proportion of licorice content of nutrient elements,and according to the different demand,put forward the corresponding optimal fertilizer proportion plan,with the total K content of licorice predictive control model parameter estimation for results,show that cultivated fertilizer,P fertilizer,reduce applying K fertilizer content,the result provides the basis for the licorice nutrient elements in the region research in the future,at the same time of licorice in the region will provide a scientific basis for cultivation and protection.
