Third-level preventing method for gummosis of stone fruit trees

Abstract

The invention provides a new method for preventing and curing the drupaceous fruit tree gummosis, namely, a three-level preventing and curing method: the leaf surface fertilization consisting of the 0.7 percent potassium chloride and boric acid are sprayed and fertilized on the leaf surface(first-level prevention and cure); after scraping the gummosis at the trunk gummosis place, the combination drug especially used for preventing the gummosis is coated, finally, the white paint is coated (second-level prevention); the soil at the tree root is loosened, the quicklime 100g and potassium chloride 50g are evenly scattered at the root inside the tree crown of each sick tree in the loose soil, and then the potassium hydroxide solution of 2000g with a mass fraction of 0.3 percent are irrigated (third-level prevention). The method has a quick effect of curing the gummosis and provides an effect for radically curing the gummosis.

Description

(1) Technical field [0001] The field of fruit tree cultivation and disease prevention and control relates to a three-level control method capable of preventing and treating stone fruit tree gummosis. (2) Background technology [0002] Gum flow disease (also known as dry rot) is a kind of disease that generally occurs on fruit trees. The disease is serious on stone fruit fruit trees such as peach, plum, apricot and cherry. Occurs commonly. The disease is not only serious in my country, but also occurs in the United States, Japan and other places according to reports. It is a worldwide disease. Its symptoms are: the outflowing glue is light yellow and transparent at first (some are colorless and transparent), and after coagulation, it gradually turns reddish brown (some are black), the diseased tissue is slightly swollen, the cortex and xylem become brown and rotten, and severe glue flow can occur. cause the whole tree to die. The occurrence of this disease often causes gre...

Problems solved by technology

[0004] Many scientific researchers have been studying this disease for many years, but most of the research reports are mainly to develop a medicament to prevent and control gum disease from the perspective of pathogens; or to develop fertilizers to prevent and control gum disease from a single nutritional point of view.

At present, there are few research reports on the prevention and treatment of gummosis caused by the joint action of physiological and non-physiological reasons.
