Description

Method for preventing and treating trunk borer anoplophora chinensis

Technical Field

The invention belongs to the technical field of fruit tree pest control, and particularly relates to a method for controlling a trunk-borer anoplophora chinensis in a forest.

Background

The star longicorn, also named orange star longicorn, bull head night fork, bull horn or flower clip worm, the larva is also called foot worm, root-coiling worm, wood-eating worm or head-surrounding worm, which is an important pest of fruit trees such as oranges, the larva is harmful to rhizomes and root cortex of plants, big cortex is usually dead, and after the larva enters xylem, the larva eats the xylem to form a worm channel, so that big leaves on the crown are withered and yellow and fall off, and even the plants die.

Adult anoplophora chinensis benth spawns within 10cm of the base of a trunk, eggs hatching larvae and are transversely damaged under the skin of the base of the trunk, if the trunk is damaged for one week, yellowing and death of the whole tree can be caused, the larvae start to be downwards and inwards eaten into the xylem and the root in the last ten days of 10 months, overwintering is carried out in the underground root, the whole process is at the hidden position, only people manually catch adult anoplophora chinensis benth or find the larvae to defecate, the larvae are dug out by a flat screwdriver in the defecate holes, the larvae are difficult to dig out due to irregular larva channels, only pesticides are inwards eaten, and the trunk damage effect is great.

According to the existing control technology of the anoplophora chinensis, microcapsule suspension emulsion such as 300 times of green Weilei is sprayed on a trunk and branches and leaves of a tree in one season, adult anoplophora chinensis is killed three times a year without seeing the killed adult, the anoplophora chinensis larva defecation holes are manually searched to find the anoplophora chinensis larva, the anoplophora chinensis defecation holes are continuously manually searched for 7, 8, 9 and 10 months after a round of the whole garden is patrolled in one year, the larva is manually dug, the labor is spent, and the trunk is greatly damaged.

Disclosure of Invention

The invention aims to make up the defects of the prior art and provides a method for preventing and controlling a trunk-boring pest anoplophora chinensis.

In order to achieve the above object, the present invention provides the following technical solutions:

a method for preventing and treating the trunk borer of forest fruit, named "Siberian beetle", features that the root and neck of trunk are wrapped by isolating bag before the adult longicorn beetle occurs and its root is extended outward to form a horn mouth.

Further, the method for preventing and treating the trunk borer anoplophora chinensis comprises the following steps:

(1) cutting the isolation bag into a rectangle with a proper size according to the diameter of the tree body;

(2) wrapping the trunk root neck part of the longicorn before the adult longicorn happens, ensuring that no bark is exposed outside, expanding outwards at the root bottom to form a bell mouth shape, and tying and fixing by using a cotton rope;

(3) burying a small amount of soil on the bell mouth of the bottom isolation bag.

Further, the isolation bag in the step 1 is selected from any one of a woven bag, a plastic bag, a gunny bag and a paperboard.

Further, the height of the isolation bag wrapping the root and neck of the trunk in the step 2 is not less than 60 cm.

Further, before the trunk root and neck part is wrapped by the isolation bag in the step 2, the coating agent is uniformly coated on the trunk skin of the wrapped part and dried in the air.

Furthermore, the coating agent is prepared from soil, lime and salt according to the mass ratio of (150-: 1: 1.5 mixing evenly to obtain the product.

Furthermore, the buried soil amount in the step 3 ensures that the bell mouth shape of the isolation bag cannot be blown up by wind.

Furthermore, the anoplophora chinensis is still found to destroy the isolation bag after the root and neck part of the trunk is wrapped by the isolation bag, so that worm eggs are laid in the tree body, and then the carved groove where the tree body is laid is lightly hammered by a hand hammer, so that a small amount of sap can just flow out.

Further, when wormholes are found in the part of the tree body during the control and the wood chips are discharged, the coating agent is treated into fine particles to be poured into wormholes, and the wormholes are sealed.

The invention has the advantages that:

aiming at the habit characteristics of oviposition of adult longicorn and overwintering of larvae in roots, the adult longicorn is induced to oviposit on a wrapping object of a trunk by using a mode of wrapping the root neck part of the trunk by using an isolation bag, the adult longicorn cannot be eaten and starved immediately after hatching on a fertilizer bag, the harm of the larvae of the longicorn in one season can be prevented by wrapping the adult longicorn in one time, manpower is saved, and the trunk is protected from being damaged by the longicorn.

Meanwhile, the coating agent is used for the wrapping part, lime and salt components can effectively expel and kill some anoplophora chinensis near the root and stem of the fruit tree, and the contained soil component is used as a second barrier, so that the anoplophora chinensis can be prevented from biting the trunk to lay eggs, and the purpose of preventing and treating the anoplophora chinensis is achieved.

The invention also aims at the situation that a small amount of anoplophora chinensis damages the isolation bag and the coating layer to lay eggs on the tree body, the carved groove is lightly hit by a hand hammer to damage the anoplophora chinensis eggs, meanwhile, the phloem of the fruit tree is not damaged, the coating agent is filled into the wormhole passage to seal the internal larvae, and the comprehensive control of the anoplophora chinensis is realized.

Detailed Description

The technical scheme of the invention is further explained by combining the specific examples as follows:

example 1

A method for preventing and controlling a trunk-boring pest anoplophora chinensis comprises the following steps:

(1) cutting the fertilizer bags into 6 small rectangles, wherein one fertilizer bag can wrap 6 trees;

(2) uniformly coating the coating agent on the surface of a trunk at a wrapping part and air-drying, then wrapping the root neck part of the trunk with the chemical fertilizer bag before the adult longicorn is grown, wherein the height of the chemical fertilizer bag is 60cm, so that no bark is exposed outside, the chemical fertilizer bag expands outwards at the root bottom to form a bell mouth shape, and the chemical fertilizer bag is bound and fixed by a plastic rope;

(3) a small amount of soil is buried on the bell mouth of the isolation bag at the bottom, so that the bell mouth of the isolation bag is ensured not to be blown and lifted by wind.

The coating agent is prepared from soil, lime and salt according to a mass ratio of 175: 1: 1.5 mixing evenly to obtain the product.

After the root and neck part of the trunk is wrapped by the isolation bag, the anoplophora chinensis is still found to destroy the isolation bag to lay worm eggs in the tree body, then a manual hammer is used for lightly smashing the groove where the tree body is laid so that a small amount of sap can just flow out, when the prevention period shows that the tree body part has wormholes and wood chips are discharged, the coating agent is processed into fine grains to be poured into wormholes, and the wormholes are sealed.

Example 2

(1) cutting the woven bag into a rectangle;

(2) uniformly coating the coating agent on the surface of a trunk at a wrapping part and air-drying, then wrapping the woven bag on the root neck part of the trunk before adult longicorn is generated, wherein the height of the woven bag is 80cm, so that no bark is exposed outside, the woven bag expands outwards at the root bottom to form a bell mouth shape, and the woven bag is bound and fixed by a plastic rope;

The coating agent is prepared from soil, lime and salt according to a mass ratio of 200: 1: 1.5 mixing evenly to obtain the product.

Example 3

(1) cutting the paperboard into rectangles;

(2) uniformly coating the coating agent on the surface of a trunk at a wrapping part and air-drying, then wrapping the paper board on the root neck part of the trunk before adult longicorn is generated, wherein the height of the paper board is 70cm, so that no bark is exposed outside, the paper board outwards expands at the root bottom to form a horn mouth shape, and the paper board is bound and fixed by a plastic rope;

The coating agent is prepared from soil, lime and salt according to a mass ratio of 150: 1: 1.5 mixing evenly to obtain the product.

Comparative example 1

Compared with the embodiment 1, the packaging treatment is carried out without using the isolation bag, and other steps are the same as follows:

a method for preventing and controlling a tree trunk borer anoplophora chinensis is characterized in that a coating agent is uniformly coated on the epidermis of the root neck part of a tree trunk and air-dried, the height of the coating agent is 60cm, and the coating agent is prepared from soil, lime and salt according to a mass ratio of 175: 1: 1.5 mixing evenly to obtain the product.

When the star longicorn is found at the root neck part of the trunk to destroy the isolation bag to lay worm eggs in the tree body, a manual hammer is used for slightly smashing the groove part where the tree body is laid so that a small amount of sap can flow out just, when the tree body part is found to have wormholes and wood chips are discharged during the prevention and treatment period, the coating agent is processed into fine particles to be poured into wormholes, and the wormholes are sealed.

Comparative example 2

In comparison with example 1, neither the wrapping treatment nor the coating with the coating agent was performed using the barrier bag.

Specific tests are as follows:

the method is implemented on pecan trees of an orchard tested by Dangshan and Hefeitongting, Anhui and Hefeitong, agriculture Limited, and the trunks are marked with red lacquer in serial numbers, and the prevention and treatment condition of larvae is checked after 3 months after each method is used for treatment. The inspection method comprises the following steps: the average number of larva corpses at the bottom of the fruit tree isolation bag, whether the surfaces of the tree bodies have wormholes or not, whether new insect feces are discharged from the wormholes or not, and if no new insect feces are discharged, the larva is considered to be dead, and the test results are shown in table 1:

TABLE 1

As can be seen from the above table, the method of the invention can effectively induce the longicorn adults to lay eggs on the package of the trunk and prevent the larvae from approaching the surface of the tree body, thereby promoting the death of the larvae, greatly reducing the number of wormholes on the surface of the tree body, improving the death rate of the larvae in the wormholes, simultaneously improving the control effect by carrying out the packaging treatment on the isolation bag and coating the coating agent, having more obvious combined effect, and leading the larvae to die possibly related to environmental factors (temperature discomfort or physical illness) in the comparative example 2 and to have abnormal death phenomenon.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
