Soft rot is a bacterial disease, with a suitable temperature range of 4-38°C and an optimum of 25-30°C. It is easy to spread under high-temperature and high-humidity conditions (generally, it starts in early and mid-June, reaches its peak in late August and early September, and then The temperature drops and the disease stagnates), which often occurs explosively, and the yield loss is serious, or even no harvest, which restricts the development of konjac industry

Abstract
The invention provides a comprehensive supporting measure and method for preventing and controlling a konjac soft rot disease. Konjac is a semi-shady plant, which prefers warmth and is afraid of high heat, prefers humidity and is afraid of waterlog, prefers cloudy days and shady places and is afraid of strong light. The konjac soft rot disease belongs to a bacterial disease; a suitable temperature ranges from 4 DEG C to 38 DEG C and the most suitable temperature ranges from 25 DEG C to 30 DEG C; the konjac soft rot disease is easy to spread under high-temperature and high-humidity conditions (the konjac soft rot disease commonly starts from the early to middle of June, reaches the peak from the last ten-day period of August to the first ten-day period of September and the disease stagnates after the atmospheric temperature is reduced; the konjac soft rot disease usually occurs explosively and the yield loss is serious, even konjac fruits are not harvested; and the development of a konjac industry is restricted. The comprehensive supporting method comprises four steps of selecting site conditions, selecting good seeds, carrying out soil treatment and carrying out field management; soil improvement and microorganism microbial fertilizer are utilized so that the konjac soft rot disease is effectively controlled and stable yield and high yield of konjac planting are realized.
Description
technical field [0001] The invention relates to comprehensive supporting measures and methods for preventing and controlling konjac soft rot, and belongs to the technical field of plant cultivation. Background technique [0002] Konjac is a semi-negative plant that likes temperature and fears high heat, prefers humidity and fears waterlogging, and prefers cloudy shade and strong light. The optimum soil pH value of flower konjac is 6.5-7.0, and that of white konjac is 7.0-7.5. Strongly acidic and alkaline soils are not suitable for the growth of konjac. Soft rot is a bacterial disease, with a suitable temperature range of 4-38°C and an optimum of 25-30°C. It is easy to spread under high-temperature and high-humidity conditions (generally, it starts in early and mid-June and reaches its peak in late August and early September. The temperature drops and the disease stagnates), often explosively occurs, and the yield loss is serious, or even no harvest, which restricts the deve...
