Abstract

The invention provides a method for preventing and treating canna edulis ker diseases. The method for preventing and treating the canna edulis ker diseases comprises the following steps that S1, hotbed seedling raising is conducted from the beginning of winter to the beginning of spring of the next year; s2, when the plant height of the canna edulis ker is 0.6-0.9 m, earthing up is conducted for the first time; s3, after the beginning of summer, when the plant height of the canna edulis ker is about 1 m and dew is not dried in the morning, 50-75 Kg of plant ash is spread per mu, and the plant ash is evenly spread on stems and leaves of the plants; s4, starting from the beginning of June, the vigorous growth period of canna edulis ker. According to the method for preventing and treating the canna edulis ker diseases through timely and high-density use of the plant ash and the EM bacterial liquid, the diseases such as anthracnose of the canna edulis ker and the like can be effectively prevented and controlled, and the yield is remarkably increased. Through popularization, the current situation that the canna edulis ker can only be continuously planted in a large area in southern high-altitude areas in China at present can be changed, the planting area of the canna edulis ker is effectively expanded, and the problem that the canna edulis ker starch market is short of supply is solved.
