High-yield bal loonflower root planting method

Abstract

The invention provides a high-yield bal loonflower root planting method which includes the steps: a, land selection and preparation; b, sowing; c, top application; d, weeding: land preparation weeding, sowing weeding, tillage weeding and harvesting weeding; e, draining water, forming a drainage gap in an inverted 'Y' shape from top to bottom between adjacent bal loonflower root trees with high bal loonflower root planting density at high temperature and humidity in summer, and planting biological fences preventing water and soil loss on a side slope between adjacent bal loonflower root planting areas; f, pinching off dead flowers; g, disease management; h, harvesting: harvesting bal loonflower roots in the same year of sowing from November to February in the following year. Water and soil loss is prevented by land selection, forestation and land preparation, prematurity and more fruiting of the bal loonflower roots are promoted, the yield and the quality of the bal loonflower roots are improved, input of chemical fertilizers is decreased, and labor input is reduced.

Problems solved by technology

[0004] In the current planting of platycodon grandiflora, soil erosion is serious, the soil layer is "thin, flat, thin", extensive management, and soil fertility decline, resulting in low yield and poor economic benefits of platycodon grandiflorum
