Saw the rotten big branches and remove them by hand. Pay attention to the smoothness of the saw mouth. If there is space, you can bridge. The dead branches of the pests and diseases should be cut off in time and taken out of the garden and burned intensively. Scrap away the diseased skin and dead tissue, and excavate the overwintering pests in the cracks of the bark. The peeling time is best performed when the sap is flowing, not too early or too late. The rotten scar should be scraped to 0.5 cm of the healthy skin, preferably in the shape of a shuttle to facilitate healing. It is also necessary to completely scrape the old wart skin and rhabdial disease tumors. Do n’t miss a tumor. The tumors of perennial and one-year-old branches must be scraped. Don't make it too deep, too shallow or too thick, and at the same time bury the diseased skin deeply. Apply all healing agents to all saws, cuts, and scars, to prevent the loss of moisture from the wound, prevent the invasion of germs, and promote healing. The diseased branches, diseased fruits, and bark of the trees under the tree were all cleared out of the garden. The fallen leaves do not need to be cleared out of the garden. They can be used as fertilizers. Combined with organic fertilizer and chemical fertilizers, the pits can be buried deeper than 25 cm under the tree. When spray buds are just germinated, spray 5 waves of meridian sulphur mixture, because when the buds just germinate, one is that the main component of calcium sulfide in the sulfur sulfide is released by hydrogen sulfide, which has the effect of killing pests and mites; It is strongly alkaline, which can penetrate and erode the waxy layer of the cell wall of pests and the body wall of pests. At the same time, strong alkalinity is not conducive to the survival of pathogens. It is difficult to invade and the diseases and insects under the membrane can not get oxygen and die, which has a better control effect on the winter diseases and insects.
