Abstract

The invention discloses a method for preventing sugar orange canker. The method includes: spraying preventive chemicals to sugar orange trees in the summer and autumn shoot growing period and the young fruit period of the sugar orange trees, wherein the preventive chemicals are mixed by 45% of polysulfide suspending agent, 30% of copper oxychloride suspending agent and water with the weight being 800-1000 times of the total weight of the polysulfide suspending agent and the copper oxychloride suspending agent; spraying the preventive chemicals every other 4 days for 3 times; spraying foliar fertilizer in the young fruit period of the sugar orange trees, wherein the foliar fertilizer comprises 30% of Bieshiman foliar fertilizer, 10% of red A boron, 57% of potassium dihydrogen phosphate and 3% of zinc fertilizer, and the foliar fertilizer is diluted 80-100 times during use and is sprayed to the tree crown. The method can effectively prevent the sugar orange canker.

Description

technical field [0001] The invention relates to the technical field of planting shatangju, in particular to a method for preventing canker of shatangju. Background technique [0002] Canker disease of Shatangju manifests as: small yellow oil-stained spots with large needles on the back of the leaves, and then turn into circular spots, both the inner and outer sides are raised and suberized, the center of the lesion is volcanic cracking, and there is yellow halo around ring. The branches and fruits are damaged, and the diseased spots are the same as the leaves, but the yellow halo is not visible. In the later stage, the leaves of diseased trees fall off, the branches die and early fruit drop. Mature fruits are covered with diseased spots, and the quality and grade are reduced. [0003] Most of the traditional methods use chemical control, but the problem with traditional methods is that they do not pay attention to supplementing fertilizer and nutrition during the disease ...
