Problems solved by technology

Although the method of intercropping can shade konjac and reduce pest damage by using the relationship of natural enemies, intercropping will cause the diversity of soil microbial populations, which makes the changes in soil structure and nutrients difficult to estimate. Secondly, intercropping will also Cause crops to compete for nutrients, which makes quality uniformity more difficult

Abstract

The invention belongs to the technical field of konjak planting, and particularly relates to a planting method for reducing the attack rate of konjak southern blight. The planting method comprises thefollowing steps of 1) soil preparation, specifically, disinfecting a planting land one month before sowing, and spraying liquid dung and a polyglutamic acid solution after disinfection; 2) seed konjak selection and treatment, specifically, selecting corms which are free of damage, disease spots and mildew and rot and have the size of 200 g-400 g as seed konjak, and performing disinfection treatment; (3) sowing, specifically, sowing the seed konjak and inoculating mushrooms at the end of March, and adopting an alternate sowing mode for the seed konjak and the mushrooms, wherein the line spacing between the konjak and the mushrooms is 0.5 m, and the plant spacing between the konjak is 0.4 m; 4) field management, specifically, topdressing nitrogen fertilizer when seed konjak seedlings emergeand leaves spread, and applying a compound fertilizer at the initial stage of expansion of new corms of the seed konjak. According to the method, by means of the konjak and mushroom intercropping cultivation mode, southern blight is reduced, and meanwhile high-yield cultivation of the konjak and the mushrooms is achieved.

Description

Technical field[0001]The present invention belongs to the technical field of konjac planting, and specifically, a planting method for reducing the incidence of konjac.Background technique[0002]The konjac stem contains glucosaccharide, which can be widely used in food, medical, chemical, paper, textile, oil and other industries, known as "Oriental Magic Powder". However, the morbidity of the white cockroaches is constantly rising, and the second largest disease after soft rot.[0003]Because the necrotic nuclear resistance is strong, it can survive in the soil for many years. In the continuous path, the number of bacteria is increasing, and the risk of incidence is constantly rising. White sick pathogens causes konjac in the case of secreting cell wall degradation, usually starts on July, and reaches the peak period in 8 and September. Currently, chemical agents are prevented. According to reports, propocyrazole, olefolols have a good inhibitory effect on iris-tapping disease, 16% Jing...
