Embodiment 1

[0020] A method for preventing and controlling long beetle larvae in a sandy texture, comprising the following steps:

[0021] (1) Water injection preparation: clean the soil in the tree tray until the roots of the tree are exposed, and the range is as large as the drip line; take a steel pipe with a length of 1.0m, flatten one end with a hammer, and leave a water outlet with a width of 0.5-2.0cm; The other end is connected to the water pump through a hose;

[0022] (2) Water injection: turn on the water pump, use the above-mentioned water injection equipment to wash the soil in the tree tray outwards, and expose the lateral roots of the trees; if new boreholes are found on the main and lateral roots, pour water into them concentratedly until the beetle larvae are washed out ; Then insert the steel pipe into the soil close to the main root and lateral root, with a depth of 60cm, and inject water along the tree tray; the water injection time for each insertion point is 8-10s, a...

Embodiment 2

[0026] A method for preventing and controlling long beetle larvae in a sandy texture, comprising the following steps:

[0027] (1) Water injection preparation: clean the soil in the tree tray until the roots are exposed, and the range is as large as the drip line; take a steel pipe with a length of 1.1m, flatten one end, and leave a water outlet with a width of 0.5-2.0cm; The other end is connected to the water pump through a hose; (2) water injection: turn on the water pump, and use the above-mentioned water injection equipment to wash the soil in the tree tray outward to expose the lateral roots of the tree; if new wormholes are found on the main and lateral roots, inject them with water Here, until the beetle larvae are washed out; then insert the steel pipe into the soil close to the main root and lateral root, with a depth of 70cm, and inject water along the tree tray; the water injection time for each insertion point is 8-10s, and the water injection time for the entire t...

Embodiment 3

[0031] A method for preventing and controlling long beetle larvae in a sandy texture, comprising the following steps:

[0032] (1) Water injection preparation: clean the soil in the tree tray until the roots are exposed, and the range is as large as the drip line; take a steel pipe with a length of 1.2m, flatten one end, and leave a water outlet with a width of 0.5-2.0cm; The other end is connected to the water pump through a hose;

[0033] (2) Water injection: turn on the water pump, use the above-mentioned water injection equipment to wash the soil in the tree tray outwards, and expose the lateral roots of the trees; if new boreholes are found on the main and lateral roots, pour water into them concentratedly until the beetle larvae are washed out ; Then insert the steel pipe into the soil close to the main root and lateral root, with a depth of 80cm, and inject water along the tree tray; the water injection time for each insertion point is 8-10s, and the water injection tim...

Abstract

The invention relates to the field of crop pest and disease control, and provides a method for preventing and treating longicorn larvae in a sandy land. The method comprises the following steps: (1) preparing water injection; (2) injecting water; (3) injecting pesticides and fertilizers into soil of a tree stump; (4) backfilling with soil and covering the tree stump. According to the method for preventing and treating the longicorn larvae in the sandy land provided by the invention, the longicorn larvae hidden in the soil and a tree root can be flushed to the ground, the longicorn larvae in the root oil can be quickly and effectively killed, a tree body is not damaged, the tree can quickly recover, the recovery rate can reach 90%, and the economic benefits are improved.

Description

technical field [0001] The invention relates to the field of prevention and control of crop diseases and insect pests, in particular to a method for controlling long beetle larvae in sandy ground. Background technique [0002] Long beetle is one of the diseases and insect pests with a high incidence rate of trees, especially in orchards, and severe cases can lead to the destruction of the entire orchard. The current method of controlling long beetle is mainly two methods of killing adults and larvae. Wherein the method for catching and killing longhorn beetle larvae mainly includes hook killing and poisoning method, as Chinese invention patent CN103300045A, discloses a kind of formula and the preparation method of trunk punching main control longhorn beetle larvae, punches on the trunk, then by injection Injecting acetamiprid into the bottle can not only kill the beetle larvae in the trunk, but also kill the leaf-eating pests. Chinese utility model patent CN201451123U disc...
