Technical Field

The invention discloses a new method for preventing and treating citrus greening disease, and belongs to the field of citrus pest control.

Background

The citrus is a favorite fruit for human beings, and the growing area and yield of the citrus are important fruits at the front of the fruit market in the world. Since the reform was open, the citrus industry in our country had gained enormous achievements, and the non-living countries were ascending the world in the vast country of citrus industry. The citrus planting area is at the first world, and the yield is at the third world.

The citrus yellow shoot is the most serious and extremely harmful infectious and destructive disease for citrus. The people are called cancer and AIDS in the plant kingdom. It is common in nearly 40 countries and regions in asia and africa. Because no good control agent and administration route are found, the problem of citrus production in the world is solved. The etiology of citrus huanglongbing has been attributed to the bacterial genus phloem, which attacks all rutaceae plants including citrus, navel orange, kumquat and citrus grocery.

The citrus huanglongbing is a very intractable disease, once infecting citrus or other fruit trees, the citrus huanglongbing is difficult to remove under natural conditions, and no effective drug treatment exists so far. Xanthorrhizosis can attack the leaves, shoots, fruits and seeds of citrus plants. When the disease is serious, most orange trees tend to be destroyed within a few years, and the bearing capacity of the plants is lost within 2-3 years after the plants are diseased. The citrus fruit trees are seriously attacked after 8-9 years of field planting even if no old fruit garden is arranged around a new fruit garden in a yellow dragon disease epidemic area, the whole plant declines within 1-2 years after the young trees are attacked, the adult trees spread to the whole plant within 2-3 years after the diseases are attacked and lose fruiting capacity quickly, and once the citrus trees are attacked, the citrus fruit trees are dug out to cause forest damage.

ProPolis (Propolis) is a fragrant and sticky gelatinous substance obtained by collecting resin from plant buds, barks, etc. by bees, mixing with glandular secretion such as bee tongue gland and cerifera gland, and processing and transforming by bees.

A large number of domestic and foreign researches show that the propolis has broad-spectrum antibiotic effect, has a very wide antibacterial range and has good antibacterial effect on some common gram-positive bacteria and gram-negative bacteria.

Disclosure of Invention

The invention aims to prevent and treat citrus Huanglongbing by utilizing broad-spectrum antibiotic action of propolis and obvious bacteriostasis on gram-negative bacteria. Eliminate the harm of the yellow dragon disease to the citrus, reduce the residue of pesticide and antibiotic and promote the development of the citrus industry.

The method of the invention is to spray the propolis ethanol water solution on the leaf surfaces of the spring tips or the autumn tips of the citrus to prevent the occurrence of the huanglongbing. The propolis ethanol water solution is sprayed on the leaves with yellow shoot to prevent and treat citrus yellow shoot. Drilling holes at the roots of fruit trees suffering from citrus huanglongbing, dripping the aqueous solution of the propolis ethanol into the drilled holes by using a hanging bottle, injecting the aqueous solution of the propolis ethanol into the roots, and utilizing the absorption and conduction functions of fruit tree tissues to enable the aqueous solution of the propolis ethanol to be absorbed and conducted at roots, stems and leaves of plants suffering from the citrus huanglongbing so as to achieve the purpose of preventing and treating. Soaking the citrus scions in the propolis ethanol water solution to prevent infection and spread of the huanglongbing in the grafting process.

Propolis is softened at 36 deg.C, has viscosity and plasticity, is dissolved at 60-70 deg.C to obtain viscous fluid, and is hardened and brittle at below 15 deg.C, and can be pulverized.

The propolis dissolving process comprises the following steps:

propolis-freezing-crushing-ethanol dissolving-propolis ethanol solution

Freezing propolis is viscous at normal temperature, and is difficult to crush, so that the propolis is required to be frozen. Freezing at-18 deg.C for 48 hr to make propolis hard and brittle. Breaking the frozen propolis in time, adding broken propolis into ethanol, stirring, and dissolving to obtain propolis ethanol solution.

The proportion of propolis and ethanol is 1-50 parts of propolis to 1-2500 parts of ethanol, and the propolis ethanol solution is prepared for standby.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the method for preventing and treating citrus greening disease is characterized by comprising the following steps:

the propolis ethanol solvent with the concentration of 1-50 percent is prepared by mixing 1-50 parts of propolis and 1-2500 parts of ethanol according to the proportion of propolis to ethanol solvent.

Preparing a propolis ethanol solvent into a solvent of 1: diluting 1-1000 times of water to prepare the propolis ethanol water solution. Spraying to the spring and autumn leaves with citrus huanglongbing to prevent and treat the huanglongbing; drilling holes at the roots of fruit trees suffering from the yellow dragon disease, and dripping the propolis ethanol aqueous solution into the drilled holes by using a hanging bottle to prevent the yellow dragon disease; and soaking the citrus scions in the propolis ethanol water solution for 10-30 minutes to prevent infection and spread of the yellow shoot in the grafting process.

The invention has the beneficial effects that: the propolis ethanol aqueous solution is adopted to prevent and treat citrus greening disease, a new way for preventing and treating citrus greening disease is developed, no pesticide pollution and residue exists, and the propolis aqueous solution is non-toxic, pollution-free, safe and effective and has great significance for promoting the development of citrus industry.

The invention has novel design, scientific and reasonable design, convenient use, good effect and wide popularization value.
