[Study of application fertilizer on Aconitum carmichaeli]

Area of Science:

• Agricultural Science
• Agronomy
• Plant Nutrition

Background:

• Aconitum carmichaeli, also known as Radix Aconiti Lateralis Preparata, is a valuable medicinal herb.
• Optimizing nutrient management is crucial for enhancing the yield and quality of agricultural crops.

Purpose of the Study:

• To investigate the effects of nitrogen (N), phosphorus (P), potassium (K), and organic fertilizer on the yield and quality of Aconitum carmichaeli.
• To determine the optimal application rates and proportions of these fertilizers for improved crop production.

Main Methods:

• A four-factor quadratic regression rotation combination design was employed.
• Agricultural biological statistics were utilized for data analysis.

Main Results:

• The application rates and proportions of N, P, K, and organic fertilizer significantly influenced the yield and quality of Radix Aconiti Lateralis Preparata.
• A regression equation was developed to accurately model these relationships.

Conclusions:

• Applying N at 13.04–15.13 kg/mu, P at 38.70–44.34 kg/mu, K at 22.50–26.46 kg/mu, and organic fertilizer at 1900–2200 kg/mu can achieve high yields (≥550 kg/mu).
• These findings provide valuable insights for sustainable and efficient cultivation of Aconitum carmichaeli.
