Flat placing, film and soil covering and side outcrop cultivation method for codonopsis pilosula

Abstract

The invention discloses a flat placing, film and soil covering and side outcrop cultivation method for codonopsis pilosula, comprises the following steps: carrying out field planting after soil preparation, fertilization and soil treatment, pulling two parallel pull lines at the edges of the two sides of a cultivation row plot in the cultivation row direction, leveling the soil between the two pull lines, flatly placing codonopsis pilosula cultivation seedlings on the ground surface within the two pull lines, enabling the seedling heads to face the same side, aligning the seedling heads with the pulling lines on the sides, making seedling bodies perpendicular to the pulling lines, spreading toxic soil into the two pulling lines after the seedlings are well placed, covering the well-placed cultivation seedlings with ground surface fertile soil outside the pulling lines, exposing the seedling heads during soil covering, then performing film covering, exposing the seedling heads out of the edge of a mulching film by 0.5-1 cm during film covering, sealing the periphery of the mulching film with soil, and covering the seedling heads exposed out of the mulching film with soil with the thickness of 2 cm; transplanting line by line; and performing field management after transplanting. By means of the flat placing, film and soil covering and side outcrop cultivation method for codonopsis pilosula, when the codonopsis pilosula is planted, the survival rate of seedlings is high, diseases and insect pests are few, the yield of codonopsis pilosula can be greatly increased, and the codonopsis pilosula is good in quality, thick in rhizome, high in medicinal value and remarkable in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese herbal medicines, and in particular relates to a side outcrop cultivation method of codonopsis pilosula covered with soil film. Background technique [0002] Codonopsis Codonopsis is a commonly used traditional tonic medicine, which has the effects of nourishing the middle and Qi, invigorating the spleen and lungs. Codonopsis also has the functions of enhancing immunity, dilating blood vessels, lowering blood pressure, improving microcirculation, and enhancing hematopoietic function. Codonopsis pilosula has strong adaptability, likes warm and cool climates, seedlings like shade, adult plants like light, can withstand high temperatures of 33°C, and can survive the winter safely in nursery fields at -30°C. Root rot is prone to occur in high humidity. Codonopsis pilosula is a plant with deep roots, the soil pH is 6.5-7.0, and continuous cropping is avoided. At present, the cultivation meth...
