Problems solved by technology

[0005] Yet the control method of existing water lice is seldom, and what is reported is mainly to adopt the chemical control method that the lime water of certain concentration is exterminated, and this method extermination effect is better, but is only suitable for the concentrated outbreak of small scale when adopting It is not suitable for large-scale prevention and cont

Embodiment Construction

[0020] The scheme of the present invention will be further described in detail below in conjunction with specific embodiments,

[0021] A physical prevention and control method for controlling the harm of water lice in mangrove clusters by using the isolation principle, the specific steps are:

[0022] Step 1, selecting mangrove plants with a ratio of dry branches to total branches of less than 30% by water lice;

[0023] Step 2: Isolate the roots of the plants at low tide; according to the shape of the roots of the plants, clean out the surrounding silt into an annular area with a width of 20 cm and a depth of 10 cm, so that the damaged parts of the roots are fully exposed.

[0024] Step 3: Wrap the root of the plant from bottom to top in multiple layers with a thin film until the upper part of the damaged plant; use a thin, soft and sticky agricultural plastic mulch film with a width of 1m for isolation treatment, from the lower part of the cleaned plant Wrapping until the ...

Abstract

The invention discloses a physical prevention and control method for treating sphaeroma hazard on a mangrove forest by using an isolation principle. The method comprises the following specific steps: selecting proper mangrove forest plants damaged by the sphaeroma; clearing roots of the plants to expose damaged portions of roots as much as possible; wrapping the plants to the upper edges of the damaged portions by using plastic films; tightly binding the upper portions with binding ropes or adhesive tapes, and covering the lower portions with sludge for sealing. By wrapping the moderately or slightly-damaged portions of plants with the plastic films, contact of the sphaeroma in decayed cavities of the damaged portions with an outer water body is reduced or isolated, and the supply of foods and oxygen to the sphaeroma in the wrapped portions is reduced, thereby trapping the sphaeroma in the decayed cavities till death, reducing damages to forests, reducing the quantity of the sphaeroma in a mangrove forest region damaged by insects, and achieving the effects of protection and prevention.

Description

technical field [0001] The invention belongs to the field of mangrove insect pest control, and in particular relates to a physical control method for controlling the damage of mangrove water lice by using the isolation principle. Background technique [0002] The water louse is one of the most common species of the crustacean Isopoda, which belongs to the phylum Arthropoda, the class Crustatacea, the order Isopoda, the family Sphaeromatidae, and the genus Hypoda ( Sphaeroma Latreille). At present, there are 93 genera and 643 species of Hydriaceae reported in the world. The geographical distribution of water louse is very wide, and it is distributed in fresh water, brackish water, intertidal zone and 1800m deep sea. The water louse is a filter-feeding animal, usually free-living, often burrowing in mangroves, coral reefs, and coastal engineering piles, destroying marine ecology. [0003] Some studies have pointed out that once mangrove plants are attacked by water lice, th...
