[Study on High-yield Cultivation Measures for Arctii Fructus]

Area of Science:

• Agricultural Science
• Agronomy
• Horticulture

Background:

• Arctii Fructus (Arctium lappa) is a valuable medicinal plant.
• Optimizing cultivation practices is crucial for maximizing yield and quality.

Purpose of the Study:

• To determine high-yield cultivation measures for Arctii Fructus.
• To analyze the impact of various cultivation techniques on agronomic traits, phenology, quality, and yield.

Main Methods:

• Field planting using a completely randomized block design.
• Evaluation of planting date, density, fertilization strategies, plastic film mulching, and topping.

Main Results:

• Optimal planting date around August 28th, density of 1,482 plants/667 m2, split fertilizer application, plastic film mulching, and topping significantly enhanced yield, plant height, thousand seed weight, and arctiin content.
• Plastic film mulching increased plant height, yield, arctiin content, and relative water content compared to open field cultivation.
• Topping increased yield by 11.09% while reducing branching by 39.89%.

Conclusions:

• Recommended high-yield cultivation measures include sowing around August 28th, a density of 1,482 plants/667 m2, split fertilization (four times), plastic film mulching, and topping during bolting.
• These integrated practices contribute to enhanced Arctium lappa production and quality.
• Early planting and topping shorten the overall growth cycle.
