Planting method for increasing kudzu powder content in kudzuvine roots

Abstract

The invention discloses a planting method for increasing kudzu powder content in kudzuvine root, comprising the steps of (1) planting site treatment: deep plowing soil of the planting site of the kudzuvine roots, then punching holes according to 180*190cm square, and then adding 100 to 200g of base materials into each hole; (2) performing fertilization management: when seedlings grow to 30cm in length, applying fertilizer according to 1300 to 1400kg per mu, and after that, applying the same fertilizer every three months; (3) lighting management: one month before picking the kudzu roots, irradiating for 2 to 3 hours every day by purple light, wherein the density of the purple light is 120 to 140lux, before irradiating by the purple light, watering to enable the relative humidity of the soil to be 80 to 85 percent. According to the planting method adopted by the invention, the kudzu powder content in the kudzuvine roots can be obviously increased; in addition, the prepared kudzu powder is rich in nutrient content, and the puerarin content and the trace element content are both higher than those of common kudzu powder available in the market.
