Method for preventing gray mold in lily flower cutting facility production in winter and heating air blowing equipment

Abstract

Provided is a method for preventing gray mold in lily flower cutting facility production in winter. Heating air blowing equipment is mounted in a lily flower cutting cultivation facility, and circulation is carried out through heated air; the heating air blowing equipment is mounted at the downwind position according to the wind direction, and a facility air outlet is reserved in the other side, opposite to the heating air blowing equipment, of the cultivation facility; air outlet temperature of the heating air blowing equipment is 20-35 DEG C; the operation cycle of the heating air blowing equipment is 3-5 times per week, and operation time is 40-60 minutes each time; the distance between the air outlet of the heating air blowing equipment and a lily plant is 1-2 m; when relative humidity in the cultivation facility reaches 60-70 %, operation of the heating air blowing equipment is stopped. The invention further discloses the heating air blowing equipment. The method solves the problem that the gray mold is prone to happening during the growth period and the flowering phase of lily flowers due to large humidity in a greenhouse; temperature in the greenhouse is increased, growth of lily flowers can be well promoted, the lily flower cutting quality is improved, the equipment is simple and low in mounting and using cost, manpower is saved, and application and popularization are easier.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to a method for preventing and controlling diseases of lily cut flowers in protected cultivation in winter. The invention also relates to the heating and blowing equipment used in the method. Background technique [0002] lily( Lilium spp. ) belongs to the perennial bulbous flower of Liliaceae Lily, and has become a mainstream product in the international flower market, second only to Anthurium and Strelitzia, and is currently one of the most popular cut flowers in the world. [0003] Botrytis cinerea is a common disease. It mainly affects leaves, but can also infect stems and flowers. Infected lily leaves and flower organs often have symptoms such as leaf scorching, deformed flower buds and wilting petals in the later stage. The optimum temperature for the growth of the mycelium of the pathogenic bacteria Botrytis cinerea is 15°C to 25°C, and 20°C is the best...

Problems solved by technology

The outdoor temperature in the northern region is very low, and heating equipment is generally used in the shed. The temperature in the shed is high, the humidity is high, and the ventilation conditions are poor. In addition, the temperature difference between the inside and outside of the shed is large, and a "water film" is easily formed on the inner side of the shed film, which is very beneficial to Botrytis cinerea. The occurrence and large-scale spread have caused great losses to lily production; in southern regions, such as Zhejiang, Fujian and other places, the humidity inside and outside the shed is very high, and there is fog in the shed, gray mold is prone to occur, and the light is poor. Lily is prone to excessive growth, resulting in poor quality of lily
