Planting method of Pueraria root

Abstract

The invention discloses a planting method of Pueraria root. The planting method includes the steps of (1) growing seedlings; (2) selecting lands; (3) performing transplanting; (4) checking the seedlings and filling the gaps with the seedlings; (5) performing weeding and fertilizing; (6) setting supports with height of 2.5-3m spaced with 0.8m; (7) reserving 4-5 main vines of each Pueraria root with lateral branches and buds cut; (8) cutting vines and digging roots in autumns and winters. According to the planting method, the lands are scientifically selected, and base fertilizer application, top dressing are reasonable, and absorption of the Pueraria root is facilitated to achieve rapid thriving of the Pueraria root with excellent root size, and potassium sulfate and calcium superphosphate are applied to facilitate germination; the Pueraria root is rapid to grow and high in quality and yield. Starch content of the Pueraria root reaches 26-27% and is greatly higher than that of wild pueriara root with 12-15%. Puerarin content of the Pueraria root reaches 2.0-2.3% and is higher than that of the wild Pueraria root with 1.4-2.0%. The Pueraria root yields 2200-2400kg / mu.
