Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing:

[0026] See attached figure 1 , Schematic diagram of water tank construction, water tank baffle plate 1 is placed on both sides of pear tree 2 rows or plant ridges (according to horizontal contour) to build a water tank, a covering film 4 is arranged in the water tank, and the covering film 4 extends to the root of the pear tree and the water tank stall Plate 1, and then fill the tank with water about 10 cm deep.

[0027] Specifically, a method for killing pear gall mosquito larvae quickly, the steps are:

[0028] (1) Build the sink:

[0029] Before the first-generation pear gall midge larvae are in full bloom in late April, water tanks were built on both sides of the trunk of Jinshui No. 1 pear tree. The water tank is made of plastic film and wooden plank, the film specification is 2m in length and 0.027mm in thickness; the plank is 2cm in thickness and 25cm in width. ...

Abstract

The invention provides a method for quickly killing dasineura pyrivora larvae. The method includes steps: 1, water tank construction, to be more specific, before a prevailing stage of first-generationdasineura pyrivora larvae in late April, constructing water tanks on two sides of a pear tree trunk, wherein the water tanks are made by plastic films 2cm in length and 0.027mm in thickness and woodboards 2cm in thickness and 25cm in width; adopting wood boards of 1.2m for two wide sides of each water tank, fixedly burying in soil by 10cm, covering upper edges of the wood boards with films, andfixing the films to the ground with soil; after construction of the water tanks, filling the water tanks with water by depth of 10cm; 2, insecticidal solution preparation, to be more specific, adopting 60% cyromazine dispersant powders for preparing 1000-fold insecticidal solution according to water injection volume. By adoption of the method, dasineura pyrivora larvae can be effectively killed without adverse influences on pear trees, the problem of damages caused by the dasineura pyrivora larvae to the pear trees in scientific research, breeding and production of pears is effectively solved,and remarkable effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of fruit trees, and more specifically relates to a method for quickly killing pear gall midge larvae, which can effectively solve the problem of pear tree damage caused by pear gall midge larvae in pear scientific research, breeding and production. This method is suitable for scientific research units, companies and individuals engaged in pear scientific research, breeding and production. Background technique [0002] Pear is an important cultivated fruit tree in China. According to the statistics of China Planting Industry Network in 2015, the planting area of ​​pear orchards in China was 1.124 million hm2, and the pear fruit output was 18.699 million tons, ranking first in the world in both area and output. Pear production has always been an important pillar industry for Chinese farmers to increase their income and become rich, and it is also one of the main agricultural products for my country's export ea...
