Embodiment 1

[0018] The present invention is as follows to the fertilization method of Qianjin Buckwheat No. 1: total nitrogen+available phosphorus+available potassium ≥ 25% and organic compound fertilizer, urea (N content is 46%) of organic matter content ≥ 25% are nitrogen fertilizer, calcium magnesium phosphate fertilizer ( P 2 o 5 The content is 8-14%) as phosphate fertilizer, potassium sulfate fertilizer (K 2 O content is 50%) is potassium fertilizer. The amount of organic compound fertilizer, N, P, and K fertilizer in the unit area of ​​the seedling field is 10kg / 667m 2 、6kg / 667m 2 、15kg / 667m 2 、15kg / 667m 2 . Organic fertilizer and phosphorus fertilizer were applied once as base fertilizer, 2 / 3 of the total amount of potassium fertilizer was used as base fertilizer, and 1 / 3 was applied as top dressing in autumn; nitrogen fertilizer was applied twice at the seedling stage and branching stage of Qianjin Buckwheat No. 1.

Abstract

The invention discloses a fertilization method for increasing the content of dimeric procyanidin in Qianjin Buckwheat No. 1. The fertilizer used in the method includes organic compound fertilizer, urea as nitrogen fertilizer, calcium magnesium phosphate fertilizer as phosphate fertilizer, and potassium sulfate as potassium fertilizer; The amount of organic compound fertilizer in the fertilizer is 10 kg / 667 m2, the amount of nitrogen fertilizer is 6 kg / 667 m2, the amount of phosphorus fertilizer is 15 kg / 667 m2, and the amount of potassium fertilizer is 10 kg / 667 m2. The fertilization method is: 2 / 3 of the total amount of organic compound fertilizer, all phosphate fertilizer, and potassium fertilizer is used as base fertilizer; 1 / 3 of the total amount of potassium fertilizer is applied as top dressing in autumn; nitrogen fertilizer is applied twice at the seedling stage and branching stage. By adopting the fertilization method of the present invention, the root yield of Qianjin Buckwheat No. 1 can be significantly increased in the year and the second year of cultivation, and the content of double procyanidin in the root of Golden Buckwheat can be significantly increased.

Description

technical field [0001] The invention belongs to the technical field of medicinal herbage cultivation, and in particular relates to a fertilization method for increasing the content of dimeric procyanidin in Qianjin Buckwheat No. 1. The fertilization method can also greatly increase the root yield of Qianjin Buckwheat No. 1. Background technique [0002] Golden buckwheat ( Fagopyrum cymosum (Trev.) Meisn.) Dicotyledonous plant of the genus Fagopyrum in the Polygonaceae family, also known as wild buckwheat, sky buckwheat, and red notoginseng. The Institute of Materia Medica, Chinese Academy of Medical Sciences isolated dimeric procyanidin (Dimeric Procyanidin, the C of 5,7,3',4'-tetrahydroxyflavan-3-ol) from the rhizome of buckwheat. 4 -C 8 dimer), hecogenin (Hecogenin) and β-sitosterol three compounds. Recently, a proanthocyanidin condensed tannin mixture with high anticancer activity was isolated from golden buckwheat root by the activity tracking method. The total tannin...
