Abstract

The invention discloses a fertilizing method of a fertilizer special for platycodon grandiflorum. The fertilizing amount is that N is 425.9-434.5kg / hm<2>, P2O5 is 141.37-144.22kg / hm<2>, K2O is 80.55-82.17kg / hm<2>, MnSO4 is 6.42-7.1kg / hm<2>, and ZnSO4 is 4.38-4.84kg / hm<2>. Two fertilizing processes including base fertilizer fertilizing and topdressing are carried out, the base fertilizer fertilizing uses 20% of N using amount, 100% of P2O5 using amount, 30% K2O using amount, 50% of MnSO4 using amount and 50% of ZnSO4 using amount, and topdressing uses 80% of N using amount, 70% of K2O using amount, 50% of MnSO4 using amount and 50% of ZnSO4 using amount. Yield of the platycodon grandiflorum increases 22.6-26.3% through optimization of major elements and microelements, and the production value improves 32.7-42.9%.

Description

technical field [0001] The invention relates to the field of bellflower planting, in particular to a special fertilizer for bellflower and a fertilization method thereof. Background technique [0002] Bellflower ( Platycodon grandiflorum A.DC.) is the dried root of the perennial herb of Campanulaceae. It is one of the 40 most sold traditional Chinese medicinal materials in my country. It is flat in nature, bitter in taste, and pungent. Efficacy of evacuating pus and eliminating carbuncle.
