Problems solved by technology

However, due to the large size and thick vertical thickness of fruit trees, spraying at different angles is required when spraying. When using this droplet test card, the water-sensitive components that reflect the droplet density will be completely washed away by the liquid, and the level of pesticides cannot be detected at all. Deposition distribution on the leaf surface

example 1

[0022] Used to study the relationship between leaf deposition per unit area and pest control

[0023] experiment method

[0024] In the peak period of a certain pest, select 6-10 fruit trees in the full fruit period, select 3-5 leaves in the east, south, west, and north of each fruit tree to investigate the base number of pests, and use Binding thing 9 fixedly binds the simulated leaf-shaped plastic sheet 2 that is consistent with the size of the real blade, the angle of the fixed simulated leaf-shaped plastic sheet 2 is as the criterion with the angle of the adjacent blade, and a clamp is used on the blade and the simulated leaf-shaped plastic sheet 2 10 clamp and fix the collector 3 . Spray with a manual sprayer, set 3-5 application rates according to the amount of pest control in actual production, and investigate the control effect of pests 1, 3, 5, 7, and 10 days after spraying.

[0025] test results

[0026] (1) Average the amount of liquid medicine collected in the f...

Embodiment 2

[0031] Determination of reasonable application amount of pesticides in apple orchards in full fruit period

[0032] experiment method

[0033] The most commonly used plunger pump sprayer is selected as the spraying device at present, and the application rate is set to three types, which are: 1 / 2 local application rate, 2 / 3 local application rate and local application rate.

[0034] Select 1 apple orchard in full fruit stage, divide it into three kinds of spraying volume areas, randomly select 9 fruit trees in the fruit trees of each spraying volume area, and 3 plants are 1 treatment, repeat three times, respectively in the selected fruit trees 2-3 blades are randomly selected on the upper, middle and lower inner chambers and outer crowns of the tree crown, and a simulated leaf-shaped plastic sheet with the same size as the real blade is fixed near each blade, and the artificial leaf-shaped plastic sheet is fixed. The angle is based on the angle of the adjacent blade, and the ...

Embodiment 3

[0043] Determination of reasonable pesticide application equipment or methods in orchards during the full fruit period (application pressure, sprayer aperture, etc.)

[0044] experiment method

[0045]The most commonly used plunger pump sprayer (spray sheet is divided into: large aperture d=1.5mm and medium aperture d=1.0mm) and a new type of mist sprayer, and the spraying amount is 1 / 2 of the local spraying amount. And 2 / 3 of the local application rate.

[0046] Other methods are with embodiment 2.

[0047] test results

[0048] (1) Measure the amount of liquid medicine collected in the simulated leaf-shaped plastic sheet collectors with different spraying treatments and different positions, and obtain the doses received by leaves at different positions. The more uniform the dose received at different locations, the better the spraying effect.

[0049] (2) Measure the amount of pesticide solution collected by the collector under different positions of the leaves under dif...

Abstract

The utility model relates to a pesticide spraying effect measuring device specially used for fruit trees, which comprises a measuring test paper, a simulated leaf-shaped plastic sheet and a collector. Determination of the water retaining agent on the test paper that absorbs the liquid medicine. The using method of the present invention is: bind and fix the simulated leaf-shaped plastic sheet on different parts of the fruit tree body with binding objects, and fix the angle of the simulated leaf-shaped plastic sheet to the angle of the adjacent leaves; clamp the collector with a clamp Fix it on the simulated leaf-shaped plastic sheet and the tip of the adjacent fruit tree leaves; bind and fix the test paper on the front and back of the leaves, the trunk, and the ground at different positions with a test paper tape, and then tear off the protective paper on the surface of the test paper. The invention can quickly measure the pesticide spraying effect under the technical conditions of different pesticide application rates, pesticide application equipment and pesticide application methods, including the amount of deposition on the leaves, the amount of loss, the amount of loss on the ground and the control effect. The invention has the advantages of simple structure, convenient operation, safety and practicality.

Description

technical field [0001] The invention relates to the technical field of measuring tools, in particular to a device for measuring whether the spraying amount of pesticides and growth regulators for fruit trees is reasonable or not. Background technique [0002] The abuse of pesticides has always been the main problem in my country's agricultural production. Due to this problem, problems such as excessive pesticide residues in agricultural products, enhanced pest resistance, and aggravated environmental pollution have occurred, especially in tall arborized fruit trees. The branches cover each other. When applying pesticides, it is difficult to evenly apply pesticides, resulting in poor pest control effects. In order to increase the control effect, farmers use spraying spraying methods to apply pesticides. Currently, fruit trees in their prime (mainly For large fruit trees such as Qiaohua apples and pears), the dosage of pesticides is more than 5-6 times that of ordinary vegetable...
