Problems solved by technology

[0005] Citrus Huanglongbing is caused by a Gram-negative bacterium limited to the phloem. It spreads quickly through psyllids and can infect a variety of Rutaceae plants, including Citrus, Hovenia, Kumquat and Murata. The enemy of planting is a disease that can cause devastating disasters to citrus. People are using various methods such as insect nets, spraying liquid, digging or cutting down citrus trees for isolation, using virus-free seedlings, etc. to prevent and control citrus yellow dragon. sick, but unsatisfactory

Embodiment 1

[0025] A control method for citrus huanglongbing, the specific steps are as follows:

[0026] Step 1: Drill downward 45-degree oblique holes evenly on the citrus trees. The depth of the holes is 2.3 cm. Avoid places where the wood is dry and where the wood is too hard. At the root, the second oblique hole is staggered from the first oblique hole, and the third oblique hole starts to move up;

[0027] Step 2, use a 50mL syringe, pull the syringe barrel to 30mL (based on the first circle of the black circle inside the syringe barrel), and then align the V-shaped center of the syringe inner rod at the 65mL position of the syringe barrel to get through When opening the hole, put the adjusted syringe handle against a stable part, such as a table, so that it is less likely to be misplaced;

[0028] Step 3, mix the preventive medicine and water evenly according to the mass ratio of 1:80, the preventive medicine includes ginger extract, purslane extract, dandelion extract and garlic ...

Embodiment 2

[0032] A control method for citrus huanglongbing, the specific steps are as follows:

[0033] Step 1: Use a 12V lithium battery and a portable electric drill with a drill bit diameter of 4mm to evenly drill downward oblique holes on the citrus tree. The angle of the oblique holes is 50 degrees. The position is preferably below the grafting interface or at the root exposed to the ground, the second oblique hole is staggered from the first oblique hole, and the third oblique hole starts to move up;

[0034] Step 2: Pull the syringe barrel to 35mL, and then align the V-shaped center of the inner rod of the syringe at the 70mL position of the syringe barrel to make a through hole. On the table, it is not easy to misplace;

[0035] Step 3, mix the preventive medicine and water evenly according to the mass ratio of 3:200, the preventive medicine includes ginger extract, purslane extract, dandelion extract and garlic extract, ginger extract, purslane extract, dandelion The mass rat...

experiment example

[0047] From 2017 to 2018, four citrus planting plots in different areas were selected in four townships in Anyuan County, Ganzhou City, Jiangxi Province. Each plot is a group, and each group has 30-100 citrus trees. Group, according to the medicine and method among the embodiment 1, carry out A, B, C, D four groups of field efficacy tests. The citrus trees in A, B, C, and D four test sites that have already produced Huanglongbing and have lost control for 2 years are injected, and the injection is divided into 4 times a year, and the time is the first ten days of March, the first ten days of May, and the first ten days of July of the Gregorian calendar. , Early September, 2017-2018, two consecutive years of experiments, and the results of statistical citrus Huanglongbing control experiments are shown in Table 3 and Table 4.

Abstract

The invention discloses a method for preventing and treating citrus yellow shoot. The problem that an existing method for treatment of citrus yellow shoot is poor in effect is solved. The method comprises the following specific steps: step 1, punching a citrus tree; step 2, performing perforating by an injector; 3, preparing a prevention and treatment liquid medicine; 4, injecting the prevention and treatment liquid medicine; and step 5, pulling out the injector, and smearing lime slurry. A prevention and treatment medicine obtained by combining plant extracts is mixed with water to form the prevention and treatment liquid medicine, and the prevention and treatment liquid medicine is injected into citrus trees by adopting an injector injection mode, so that the medicine rapidly enters phloem of diseased trees, has an obvious inhibition effect on gram-negative bacteria causing the yellow shoot, and can effectively kill pathogens, and the citrus tree body generates an antibody and is notafraid of secondary pathogen transmission of phylloxera, so that the purpose of preventing and treating citrus yellow shoot is achieved, the operation is simple, time and labor are saved, economic losses caused by digging or cutting off citrus trees are avoided, and the application prospect is wide.

Description

technical field [0001] The invention relates to the field of citrus prevention and control, in particular to a method for the prevention and treatment of citrus huanglongbing. Background technique [0002] With the improvement of people's living standards and the increase of people's economic income, people can have more money to buy the food they need, and fruit is the food that people buy most often. [0003] Fruit refers to edible plant fruit that is juicy and mainly tastes sweet and sour. Fruits are not only rich in nutrients, but also can promote digestion. Citrus is one of the common fruits. [0004] Citrus is a plant belonging to Rutaceae. It likes a warm and humid climate, and its cold resistance is slightly stronger than pomelo, lime, and sweet orange. Rutaceae Citrus subfamily is distributed between 16°-37° north latitude. It is a tropical and subtropical evergreen fruit tree. Citrus is a general term for tangerine, tangerine, orange, kumquat, pomelo, and orange....
