Research method for effects of fertilizing amount of compound fertilizer on nicandra physalodes

Abstract

The invention discloses a research method for effects of fertilizing amount of a compound fertilizer on nicandra physalodes. The research method comprises the following steps: S1, experimental design:applying a base fertilizer when the nicandra physalodes are sowed, and applying the compound fertilizer once at the branching stage and flowering stage; meanwhile, weeding timely and carrying out cultivation and banking combined with weeding so as to avoid lodging; selecting 5 to 11 kg / mu of an N fertilizer, 20 to 30 kg / mu of a P fertilizer and 8 to 15kg / mu of a K fertilizer and carrying out experimental design according to an orthogonal test. The research method disclosed by the invention shows that by proportioning and fertilizing according to the ratio of nitrogen to P to K being 11 to 25to 8, the maximum influence on the stem yield, seed yield and plant yield of each plant of the nicandra physalodes is achieved; the average seed weight of each plant reaches 56.64 g, the average valueof seed production reaches 218.55 Kg / mu and the average plant yield reaches 849.60 Kg / Mu, so that the mixed application of 11 Kg / mu of the N fertilizer, 25 Kg / mu of the P fertilizer and 8 Kg / mu of the K fertilizer has the optimal effects on the reproductive traits and yield traits of the nicandra physalodes; the problem that the nicandra physalodes cannot grow regularly due to improper fertilization is solved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for researching the effect of the amount of compound fertilizer on plant growth. Background technique [0002] Daqiansheng is a plant of the genus Pseudophysalis of the Solanaceae plant, native to Peru, also known as Pseudophysalis, Tianzhu and so on. Born in fields, wastelands, fences, and around gardens, it is used for medicinal or ornamental cultivation in the north and south of my country. The whole plant has the effects of calming, eliminating phlegm, clearing away heat, detoxifying, and relieving cough, and can treat mental illness, rabies, colds, and rheumatism. , Scabies and other diseases. The seeds have the effects of clearing heat and annealing, diuretic, expelling wind, and anti-inflammatory, and can treat fever, rheumatoid arthritis, sore carbuncle, swelling and pain. The flowers have the functions of expelling wind and reducing inflammation. Tre...
