Description

[0002] The small green leafhopper is also known as the peach leafhopper, small green leafhopper, etc., a little leafhopper, peach duster, and belongs to the order Homoptera, Cicadidae. Every year from March to April, it migrates to the tender leaves of tea and sucks them to cause damage. At first, some yellow-white spots will appear on the damaged leaves. In severe cases, the spots are connected, making the whole leaf pale and falling early. Therefore, it is necessary to take insect and pest control measures against the small green leafhopper.

[0003] Traditional green leafhopper pest control generally uses the yellow board trapping method to monitor green leafhoppers, and then manually observes the yellow boards. This method is not only inefficient, but also difficult to grasp the insect dynamics of green leafhoppers in tea gardens in real time, which makes it difficult to accurately calculate the number of insects on the yellow boards in the later stage.

[0063] In addition, the present invention also provides a method for monitoring green leafhoppers in a tea garden based on color plate induction counting, comprising the following steps:

[0064] S1: Fixing the color plate assembly 100, specifically including the following steps:

[0065] S101: placing the color plate assembly 100 at a selected position so that the fixing mechanism 180 is in contact with the ground;

[0066] S102: Adjust the telescopic rod 140 to drive the first fixed rod 120 to move up and down so that the orange plate 110 is at a required height;

[0067] S103: One mu of land in the tea garden is selected as the monitoring land, and sampling is performed according to the 5-point method. Each sampling point follows the steps of S1, and an orange board 110 is vertically placed above the tea tree. The bottom of the orange board 110 is 10 cm away from the tea canopy surface, and the orange board 110 is placed in the east-west direction;

[0068] S2: Monitoring the use of the component 200, specifically including the following steps:

[0069] S201: placing the monitoring component 200 opposite to the color plate component 100, so that a suitable distance is maintained between the monitoring component 200 and the color plate component 100;

[0070] S202: Make the support leg 290 of the monitoring assembly 200 fit the ground;

[0071] S203: Control the moving rod 260 to move up and down along the barrel 270 so that the camera 240 and the orange plate 110 are at the same level, and tighten the hand screw 271 to fasten the moving rod 260 and the barrel 270;

[0072] S204: Manually rotate the camera 240 by the turntable 242 so that the camera end of the camera 240 faces the orange plate 110 to collect images of the orange plate 110;

[0073] S205: The camera 240 takes pictures at regular intervals to collect images of the orange board 110. By processing and identifying the images, the number of insects for several consecutive days is calculated. The obtained number of insects is processed using a moving translation method to obtain a change trend of the number of insects.

[0074] The moving average method is used to analyze the collected data. The moving average method is a common method that uses a set of recent actual data values ​​to predict the demand for company products, company production capacity, etc. in the next one or several periods. The moving average method is suitable for immediate prediction. Therefore, this method can be applied to the real-time monitoring of green leafhoppers.

[0075] The number of insects on the five yellow boards was counted through the monitoring system once a day, and then the values ​​on the five yellow boards were summarized. The survey specification for green leafhoppers specified in DB 33 / T 867.4-2012 requires a survey every five days, so the moving average was calculated based on the survey specification with five days of data as a group.

[0076] Calculation formula:

[0077] Moving average of insect counts for 5 consecutive days:

[0078] MA=(N d-1 +N d-2 +N d-3 +N d-4 +N d-5 ) / 5;

[0079] Note: N d-1 、N d-2 、N d-3 、N d-4 、N d-5 They represent the observed values ​​of yellow plate worm numbers for 5 consecutive days.

[0080] Result judgment: If the moving average value increases continuously, it means that the number of insects in the tea garden is on an increasing trend; if the moving average value decreases continuously, the number of insects in the tea garden is on a decreasing trend.

[0081] Example 2

[0082] Different from implementation 1, in S205, the obtained insect number information is processed using a regression coefficient method to obtain the changing trend of the insect number.

[0083] The data was processed using the regression coefficient method. The number of insects on the five yellow boards was counted through the monitoring system once a day, and then the values ​​on the five yellow boards were summarized. Regression analysis was performed on the collected data, and the regression coefficient value was calculated once every five days.

[0084] Calculation formula:

[0085] Regression coefficients:

[0086]

[0087] Note: i represents the number of days, where the number of days is 1-5 consecutive days, N i represents the daily insect population, It is the average number of insects in 5 days.

[0088] Result judgment:

[0089] If the regression coefficient is positive, it means that the insect population in the tea garden is on the rise; if the regression coefficient is negative, it means that the insect population in the tea garden is on the decline; the larger the positive value of the coefficient, the faster the growth rate, and the larger the negative value of the coefficient, the faster the decline rate.

[0090] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
