Problems solved by technology

However, most of the research on direct use of repellent plants to control pests has focused on Bemisia tabaci (Carvalho et al.2017, Wu Yahong et al.2019). For example, in pepper fields intercropping celery at a ratio of 3:1, the population reduction rate of Bemisia tabaci reached 86.67%. (Hengsen et al.2017)
However, many studies have only studied the effect of repellent plants in a short period of time, and have not studied the repellent effect of the whole growth cycle of crops in actual production applications. Therefore, it is necessary to provide production management methods for green peach aphid repellent plants

Embodiment 1

[0027] Embodiment 1, the control of the repellent plant management of greenhouse green peach aphid

[0028] For the control of peach aphid in the greenhouse, mung bean and mint were used as repellent plants.

[0029] (1) Half a month before pepper planting, the mung bean seeds were broadcast live at a plant spacing of 50 cm at the vent under the greenhouse, and the mint 4-leaf stage seedlings were transplanted and planted in 2 rows.

[0030] (2) After two months, appropriate management such as leaf thinning and top removal should be carried out once a month to ensure that the growth of the repellent plants is controlled and the ventilation function of the vents is not affected.

[0031] (3) Use the organic vegetable management standard to carry out daily agricultural operations. After 17 days of pepper planting, start to regularly investigate the number of peach aphid on pepper plants. Randomly investigate 2 leaves in each of the , middle and lower layers, and record the numb...

Embodiment 2

[0036] Embodiment 2, the management of repellent plants of preventing and controlling green peach aphid

[0037] For the control of green peach aphid in the greenhouse, coriander and celery were used as repellent plants.

[0038] (1) Half a month before the eggplants were planted, the coriander seeds were broadcast live at a plant spacing of 50 cm at the vent under the greenhouse, and the 4-leaf stage celery seedlings were transplanted and planted in 2 rows.

[0039] (2) After two months, the top removal management is carried out once a month to ensure that the growth of the repellent plants is controlled without affecting the ventilation function of the vents; and new seedlings are raised for later replanting. After three months, the celery and coriander can be cut in batches, and new seedlings can be replanted to ensure the continuous repelling effect on the green peach aphid.

[0040] (3) Use the organic vegetable management standard for daily agricultural operations. Afte...

Embodiment 3

[0045] Embodiment 3, the influence of repelling plants on the individual and population growth of Myzus persicae

[0046] The leaf disc method was used to clarify the effect of repellent plants on the individual growth of Myzus persicae. Pepper leaves with the same size and status and repellent plant leaves (about 3.0 g) with the same size and status were selected, and the treatment group was set: 1 pepper leaf and repellent plants Leaves were placed on both sides of the petri dish, and a control group with only one pepper leaf was set. The leaves were placed in a plastic petri dish (D=14cm, H=2cm), and the petioles were wrapped with moist absorbent cotton to maintain leaf activity. 20 8-day-old Myzus persicae were released in the middle of the dish, and each treatment was repeated 20 times. The location and number of peach aphid were recorded at 1 and 2 hours, respectively. Peach aphid repelling rate: RI=(C-P) / C*100%, P is the number of peach aphids in the treatment group, a...

Abstract

The invention discloses a repellent plant management method for preventing and controlling green peach aphids in a greenhouse. The repellent plant management method comprises the following steps: within half a month before vegetable field planting, planting repellent plants at ventilation openings under a greenhouse, and carrying out conventional fertilizer and water management; 2 months after planting, normal farming management such as leaf thinning and topping is conducted once every 15-30 days, and the ventilation function of the ventilation openings is not affected while it is guaranteed that the growth vigor of the repellant plants is controlled; the vegetable is pepper, and the repellent plant is mint or mung bean; the mung bean seeds are directly sown according to the plant spacing of 40-60 cm or peppermint seedlings in the four-leaf stage are transplanted and planted; the vegetables are eggplants, and the repellent plants are celery or coriander. The method can effectively reduce the occurrence rate of aphid populations and prevent vegetables from being seriously damaged by green peach aphids.

Description

technical field [0001] The invention relates to a plant management method for preventing and controlling green peach aphid, belonging to the field of agricultural technology protection. Background technique [0002] The green peach aphid Myzus persicae (Sulzer) belongs to the Hemiptera family Aphididae, also known as Myzus persicae. It is one of the important pests of facility vegetables. It is widely distributed in all parts of the country and has more than 400 kinds of host plants in 50 families. Myzus persicae mainly feeds on the back of plant leaves, causing the plants to fall leaves, yellow, wilt, and even die. The honeydew secreted on the surface of the leaves reduces the photosynthesis efficiency of plants, and also causes mildew and seriously reduces product quality. In addition, the green peach aphid can transmit more than 100 plant viruses, seriously affecting the yield and quality of crops. [0003] At present, chemical control measures are commonly used in the p...
