Method for preventing disease of konjac

Abstract

The invention relates to a method for preventing disease of konjac, and the method comprises the following five aspects of: konjac seed treatment, soil treatment, sowing pre-treatment, a sowing method and field management. The method disclosed by the invention has the beneficial effects that the konjac seed treatment is carried out, thus diseased konjac seeds can be avoided from being mixed and the konjac seeds can be prevented from being infected with a disease; the soil treatment is carried out, thus harmful bacteria can be avoided from being carried in soil, the harmful bacteria in the soil can be killed, and meanwhile the living environment of the harmful bacteria can be destroyed; the sowing pre-treatment is carried out, thus the diseased konjac seeds can be avoided from being mixed, the disease resistance of the konjac seeds can be enhanced, and sprouting and sowing can be used for reducing the opportunity that the harmful bacteria are immersed into the konjac seeds; interplanting can be used for reducing the survival chance of the harmful bacteria and filtering part of sunlight, and a base fertilizer is applied well, thus top dressing can be reduced, and the influence on a konjac plant can be reduced; the filed management can be used for preventing the harmful bacteria from intruding in the whole journey; and a series of comprehensive methods can be used for preventing the disease of the konjac in every aspect.

AI Technical Summary

Problems solved by technology

In 2006, domestic and foreign demand for fresh konjac was 900,000 tons, while the output was only 520,000 tons, far from meeting the demand

[0007] Since the 1980s, Chinese konjac has started to develop industrially. However, due to the late start, there has been no major breakthrough in planting technology, especially in the prevention of konjac diseases. There is no effective method. Once encountering diseases, they can only watch. There are mainly 13 kinds of konjac diseases, among which bacterial diseases include konjac soft rot and konjac bacterial leaf blight, and fungal diseases include konjac white silkworm, konjac anthracnose, konjac root rot, konjac Fusarium wilt, konjac white-spotted feather disease, konjac ring spot disease, konjac purple rot, etc., physiological diseases include konjac leaf burn disease, konjac yellow albinism, etc., and konjac virus disease and konjac nematode disease; these Diseases restrict konjac production and industrial development
