Embodiment 1

[0023] 1. Preparation of Piroformis indica Fermented Liquid

[0024] Pick 2 pieces of bacterial blocks with a diameter of about 5 mm from the edge of the Pyriformis indica colony preserved in the rooting medium of gerbera tissue culture plantlets, and place them in a 250 ml Erlenmeyer flask containing 100 ml of sterilized PDA liquid medium Cultivate in a shaker at 28°C and 120 r / min for 3 days, collect the filtrate after filtering through a single layer of gauze, and dilute with water to obtain a spore concentration of 5×10 5 Individual / ml Indian Piroformis fermented liquid;

[0025] 2. Inoculation of Piriformis indica and transplantation of gerbera plantlets

[0026] Two days after opening the cover and hardening the seedlings of ‘Linglong’ gerbera with good rooting, the root system was washed, soaked in the fermentation broth of Pyromorpha indica for 2 hours, and then transplanted into the substrate;

[0027] 3. Preparation of Phytophthora cryptophytophthora fermentation b...

Abstract

The invention provides a method for improving the root rot resistance of gerbera chrysanthemums, obtaining gerbera chrysanthemums colonized by Pyromorpha indica through root soaking method, improving the root rot resistance of gerbera chrysanthemums, and improving the commercial value of gerbera chrysanthemum plants is of great significance. The invention has simple steps, strong operability and remarkable effect.

Description

technical field [0001] The invention relates to the technical field of gerbera chrysanthemum seedling cultivation, in particular to a method for improving gerbera chrysanthemum root rot resistance. Background technique [0002] Gerbera ( Gerbera jamesonii Bolus) is one of the world's five largest fresh-cut flowers and is a perennial herbaceous flower. It has various flower colors, tall and straight flower branches, long flowering period and is not easy to decay. It is deeply loved by flower growers and consumers, and has extremely high economic value. In recent years, with the continuous expansion of planting area, gerbera diseases, especially root rot, have become more and more serious, which has become an important problem restricting the healthy development of my country's gerbera industry. [0003] Pyromorpha indica has a wide host range, and it has a wide range of effects on promoting growth and enhancing plant resistance to biotic and abiotic stresses for its host p...
