Problems solved by technology

At present, there is no effective pesticide for the prevention and treatment of Phalaenopsis bacterial soft rot, and antibiotics such as streptomycin or copper fungicides are commonly used in production for prevention and control; however, antibiotics are expensive and prone to drug-resistant bacteria; the use of copper Fungicides are prone to phytotoxicity at high temperatures, and a large amount of use will increase the risk of metal pollution to the environment; the market needs a pollution-free method that does not require the use of antibiotics to prevent and treat Phalaenopsis bacterial soft rot. The present invention solves such problems

Abstract

The invention discloses a method for preventing and controlling phalaenopsis bacterial soft rot through environment regulation. The method includes: putting cupped seedlings in environment with highest value of day temperature ranging from 25 DEG C to 27 DEG C, highest value of night temperature ranging from 22 DEG C to 24 DEG C and highest value of relative air humidity ranging from 65% to 70% for culture. By controlling highest day temperature, highest night temperature and highest humidity value of a greenhouse, incidence rate of phalaenopsis bacterial soft rot is lowered, and the method ispollution-free, low in cost and good in effect.

Description

technical field [0001] The invention relates to the field of Phalaenopsis cultivation, in particular to a method for preventing and controlling Phalaenopsis bacterial soft rot through environmental regulation. Background technique [0002] Phalaenopsis soft rot (Erwinia Carotovora Pvcarotvora) is a bacterial disease of the genus Erwinia. The pathogen invades the Phalaenopsis plant through the plant wound and stomata to cause disease. Generally, it is easy to occur when high temperature, high humidity and poor ventilation, especially It is more likely to occur when too much nitrogen fertilizer is applied. [0003] Different parts of Phalaenopsis leaves at all ages can be infected. When the leaves are damaged, small circular water-stained spots first appear, which are translucent when facing the light source. The damaged tissue is soft and smelly, and the leaves lose their support and droop. There is only a layer of transparent surface tissue on the outside, and there is ranc...
