Embodiment 1

[0012] A method for preventing and treating hawthorn ring disease, comprising the following steps:

[0013] (1) Within 3 days before the hawthorn completely fades, mix potassium dihydrogen phosphate, refined biogas slurry, calcium chloride, 50% carbendazim wettable powder, and water at a mass ratio of 7:200:2:1:300. Obtain the protective solution A, irrigate the roots once, dilute the bactericidal solution A by 2 times, and spray it once on the branches of the hawthorn tree; the finely filtered biogas slurry is the filtrate obtained by filtering the biogas slurry stock solution through 120 mesh;

[0014] (2) In mid-June, mix urea, refined biogas slurry, 1.1% matrine powder, and Bordeaux mixture at a mass ratio of 4:100:1:100 to obtain protective solution B, irrigate the roots once, and directly spray on the branches of hawthorn Spray once on the top, and spray again in late June; the preparation ratio of the Bordeaux mixture is 1:1:150;

[0015] (3) In mid-July, the dandelion...
