Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a release method of fleahopper harsii of the present invention is shown, which specifically includes the following steps:
s1, dividing release cells on cabbage in the heading stage, releasing a plurality of nymphs and adults of 3-5 years old on each cell, placing a monitoring device in each release cell, monitoring the growth condition of cabbage in each release cell, and recording and calculating the number of pests in a background;
in the cabbage balling stage, release cells are divided into cabbage areas, pests in the areas can be effectively placed in a targeted mode, the pest killing effect of the fleshy bugs is maximized, the area of each release cell is 0.5-2 square meters, in the embodiment, the area of each release cell is 1 square meter, 5-8 cabbages are placed in each release cell, and a sealing cover is arranged on each release cell, so that each release cell is separated from each release cell, and the fleshy bugs can be prevented from flying away in the release areas.
The monitoring device is arranged in the release cell and used for monitoring the conditions of the fleshy bug and the pests in the release cell, the used monitoring device can be a camera or a sensor, in the embodiment, the used monitoring device is a camera, the monitoring device is connected with the management background, monitored data are transmitted to the management background, and the change of the quantity of the pests and the quantity of the pests in the release cell are recorded and calculated.
The recording time intervals are 1 day, 2 days, 3 days, 5 days, 7 days and 9 days after release, the recording frequency is increased, and the accuracy of monitoring and recording can be improved.
The background calculation comprises the steps of calculating the elimination rate and the relative control effect of pests, wherein the elimination rate (%) of the pests is (the population base before control-the population occurrence amount after control) multiplied by 100/the population base before control;
relative control (%) ═ insect population reduction rate ((insect population reduction rate-control area insect population reduction rate)/(100-control area insect population reduction rate)) × 100.
The harlequin plant is used for pest control in the release area, so that the pest control capability of the harlequin plant can be greatly increased.
In this embodiment, three release cells are set, the benefit-to-harm ratio of each release cell is 0.1, 0.2, and 0.3, and the control effects of the three release cells after release of harris baccarum for 1 day, 2 days, 3 days, 5 days, 7 days, and 9 days are recorded, as shown in table one below, in the release cells with benefit ratios of 0.2 and 0.3, after release of harris baccarum, the control effects of 92.6% and 93.1 can be achieved on day 9. In field application, a more economic and effective benefit ratio is recommended to be selected, namely the ratio of the release amount of the harlequin bugs to the field insect population is 0.2, so that a good control effect can be obtained. Meanwhile, in practical field application, after the harlequin fleshy bugs are released for three days, the harlequin fleshy bugs egg masses are found in the field, and nymphs of 1 year old on the 9 th day hatch out, so that the field adaptability is strong, and the control effect lasting capacity is strong.
S2, after the nodulation period, transplanting the cabbages, subdividing the transplanted cabbages into processing cells, releasing a plurality of adults in the middle of the processing cells, arranging an isolation region between each processing cell and each processing cell, namely, respectively arranging isolation cells at two sides of each processing cell, placing a monitoring device in each processing cell, monitoring the growth condition of the cabbages in the processing cells, and recording and calculating the quantity of pests in a background;
the area of the processing cell is 40-60 square meters, the area of the isolation cell is 5-15 square meters, in this embodiment, the area of the processing cell is 50 square meters, the area of the isolation cell is 10 square meters, and the isolation cells are respectively arranged on two sides of the processing cell so that the harris baccarum in each processing cell can intensively process pests in the region and improve the control efficiency; and meanwhile, the monitoring device in the processing cell is responsible for monitoring, recording and processing the number of the harris baccarum and the number of the pests in the cell and sending the number to the management background for statistical management, and the recording time interval is 7 days, 14 days, 21 days, 28 days, 35 days and 42 days after the harris baccarum is released.
In the embodiment, three treatment cells are arranged in total, the pest number of the three treatment cells is M, M is respectively M is less than or equal to 10, M is more than 10 and less than or equal to 30, and M is more than 30 and less than or equal to 50, 50 harlequin bugs are placed in the three treatment cells, the control efficiency is recorded and calculated, and as shown in small table II, the control effects are respectively obtained in 7 days, 14 days, 21 days, 28 days and 35 days after the harlequin bugs are released. According to the second table, when the number M of the field pests is less than or equal to 10, the control effect reaches 85.2% after 7 days of releasing the harpacris serissoides, the control effect is the highest after 14 days and is 95.3%, 75.4% of control effect still exists after 28 days of releasing, and the calculation formula is the same as that of the step S1; and the later the release period is, the greater the effect on the control effect is. And under the condition that the control effect is more than 60%, the 1-time release of the harpacris loti can continuously control the damage for about 1 month, which shows that the harpacris loti has high-efficiency and continuous control capability.
S3, repeatedly releasing the fleshy flemingia furcifera every 25-35 days, monitoring the growth condition of the cabbages, and feeding the growth condition back to the background until the cabbage grows.
In the embodiment, the cabbage planting area with the benefit-harm ratio of 0.2 is subjected to multiple release comparison, and the first pair releases 1 time of harlequin fleshy bugs on the 5 th day after the cabbage planting according to the benefit-harm ratio of 0.2; the second pair starts to continuously release 2 times of fleshy bugs on the 5 th day after the cabbage is fixedly planted according to the benefit-harm ratio of 0.2, and the interval is 7 days; the third pair starts to continuously release 3 times of fleshy bugs on the 5 th day after the cabbage is fixedly planted according to the benefit-to-harm ratio of 0.2, and the interval is 7 days; as shown in table three, the control effects of 7 days, 14 days, 21 days, 28 days, 35 days, 42 days and 53 days are recorded for the three treatments, harris baccans are all released in the middle of the field planting area, an isolation area is formed by other crops in the treatment room, and according to table 3, harris baccans are continuously released for 3 times in the 5 th day after the cabbage field planting, so that the method is more favorable for natural enemies to establish a population in the field, can continuously control the plant damage until the cabbage is harvested, and can keep the control effect of more than 80%.
In the embodiment of the invention, different released harlequin glorybower bugs are arranged at different planting stages of cabbage, so that the harlequin glorybower bugs can be efficiently deinsectized, and after the harlequin glorybower bugs are released, the harlequin glorybower bugs can lay eggs in the field and continuously propagate, and the release time is 1 time, so that the control effect can be maintained for 1 month by more than 60%; the earlier the release period, the better the control effect, and the continuous release is carried out for 3 times, the interval period is 7 days, the population establishment of the natural enemy in the field is facilitated, the control effect is more obvious and durable, and the continuous pest control in the field can be realized.
