Description

Method for preventing occurrence of olive trunk-boring pests Technical Field The invention relates to the technical field of prevention and control of olive pests, in particular to a method for preventing the occurrence of olive trunk-boring pests. Background The olive oil is a famous woody oil tree species in the world, and the evergreen arbor in the oleaceae is praised as liquid gold by virtue of the miraculous health care effect of the olive oil processed by fruits, and is deeply loved by people in all countries in the world. In the key technology of olive high-yield cultivation, prevention and control of olive diseases and insect pests, in particular, prevention and control of insect pests are important technical components. The olive plant is characterized in that the olive plant is subjected to a variety of diseases and insect pests, the diseases are more in anthracnose and root rot, the insect pests are more serious in damage to trunk-boring pests such as longhorners and large-grain cross-furrow weevils, early plants are found after the trunk-boring pests are partially damaged, the early plants can be saved by timely removing the plants, but the recovery of the treated tree vigor requires a long time, the later serious plants are partially found, the insect pests cannot be treated, and the whole tree gradually withers and dies. Therefore, the occurrence of the dry borer of the olive is reduced, and the method is important to the improvement of the planting benefit of the olive. The existing method generally sprays chemical agents to prevent and control pests, but the chemical agents are easy to pollute the ecological environment, and the chemical agents are sprayed when the occurrence of the pests is generally observed, and the pests generally cause harm to plants at the moment, so that the prevention and control are easy to be untimely. The spraying for many times in advance can increase the prevention and control cost and the harm to the ecological environment, and the long-time spraying can also cause the pests to generate drug resistance, so that the later prevention and control difficulty is increased. Therefore, it is required to find a pest control method suitable for the olive, which can effectively control pests in time while reducing the usage amount of chemical drugs, and reduce the occurrence rate of the dry pests of the olive so as to improve the planting benefit. Disclosure of Invention In view of the above, the invention aims to provide a method for preventing the occurrence of the stem borer of the olive, which solves the problems that the conventional chemical agent prevention method is not timely in prevention and treatment, the prevention and treatment effect and the prevention and treatment cost cannot be considered, and the damage to the environment is large. The invention solves the technical problems by the following technical means: A method of preventing the occurrence of olive trunk-boring pests, the method comprising the steps of: (1) In 12 months, brushing a long-acting protective agent for the forest tree along the position from the bottom of the tree disk to the height of 50-80 cm of the trunk on all days; (2) Preparing a lime sulphur agent after brushing a long-acting protective agent, adding water into the lime sulphur agent to dilute the lime sulphur agent to have a Baume degree of 2-3, uniformly spraying the lime sulphur agent onto the surfaces of olive plants from top to bottom and from inside to outside, spraying the lime sulphur agent for 1-2 days, applying a stabilizing agent on the surfaces of soil, and then paving a mulching film; (3) Removing the laid mulch film in 3 months of the next year, taking the lime sulfur mixture prepared in the step (2), diluting to the Baume degree of 0.2-0.5, and then performing secondary spraying; (4) Spraying lime sulfur agent for 8-12 days, then taking quicklime on the surface layer, splashing water to naturally slake the quicklime for 24 hours to obtain slaked lime, and uniformly spreading the slaked lime along the range of 20-50 cm around the trunk of the olive; (5) And (3) installing the insecticidal lamps in the olive planting field according to the density of 1 insecticidal lamp per 10-20 mu of field to perform physical insecticidal. Further, the preparation method of the lime sulphur in the step (2) comprises the following steps: And mixing and decocting quicklime and sulfur in a mass ratio of water to water of 1 to 2 to 10, wherein the baume degree of the lime sulfur mixture is 20-28 ℃. Further, the stabilizer in the step (2) comprises the following raw materials: glycerol, phosphorus pentoxide, tartaric acid, xanthan gum, methylene blue, sodium hydroxide, kaolin, malonic acid, p-toluenesulfonic acid and sodium carboxymethylcellulose. Further, the preparation method of the stabilizer comprises the following steps: Placing glycerin into a reaction kettle, dividing phosphorus pentoxide into equal 3 parts, adding the equal 3
