Description

Functional plant-based green prevention and control method for wolfberry pests Technical Field The invention belongs to the technical field of ecological regulation and control of agricultural pests, and relates to a functional plant-based green control method for wolfberry pests. Background Medlar is an important dominant characteristic industry in northwest areas, and the quality safety of products is of great concern. Because the pests in the production of the medlar have serious occurrence, especially the piercing-sucking pests such as aphids (winged aphids and wingless aphids), psyllids and the like have high outbreak frequency, the drug resistance is enhanced, the prevention and control difficulty is very high, the output and quality of the medlar are seriously restricted, and the medlar is prevented and controlled by long-term chemical pesticides, and the traditional clear-tillage or single planting mode causes simple field habitat, and natural enemies such as ladybug, green lacewing and the like lack of habitat and alternative food lack. In recent years, although the idea of controlling insects by grass exists, the variety of functional plants suitable for the Ningxia dry-farming medlar garden is not clear, and the screening work of the functional plants is lagged. Functional plants such as cnidium monnieri are planted in medlar gardens mainly in Ningxia, and have hidden trouble that the plant waiting period is not matched and the plant is easy to become a middle host of secondary pests (such as millet plant bug). Therefore, a need exists to screen out functional plant species and ecological planting patterns that can adapt to local climates, effectively block the colonization of medlar pests and preserve natural enemies for a long time. Disclosure of Invention The invention aims to provide a functional plant-based green control method for medlar pests, which can reduce the propagation and harm of medlar aphids and is an ecological control method for improving the diversity of natural enemies. The invention provides a functional plant-based green control method for medlar pests, which comprises the following steps: 1) Functional plant planting belts are arranged at the edge of a medlar plantation or at two sides of a working channel; 2) Selecting seeds of the functional plants, and sowing the seeds on the functional plant planting belt to obtain a functional plant belt; The functional plant is selected from at least one of astragalus, starwort root and baikal skullcap root; 3) Performing water and fertilizer integrated management on the functional plant belt and the medlar plantation; 4) And a hanging armyworm plate is arranged above the functional plant belt, the migratory quantity of winged aphids is monitored, the occurrence trend of wingless aphids on field medlar branches is predicted based on the winged aphid trapping quantity, and the accurate control of medlar pests is guided. In the method, the width of the planting belt can be 0.5-1.0 meter; The buffer distance between the planting belt and the water dripping line of the medlar tree crown is kept 0.5-1.5 meters, so that ventilation, light transmission and smooth mechanical operation are ensured. The invention reserves the buffer space not only for reducing direct resource competition among plants, but also for reserving agronomic operation space, is convenient for workers to carry out manual operations such as fruit picking and pruning, meets the passing requirements of agricultural mechanized operations such as plant protection unmanned aerial vehicles, weeder and the like, ensures that the construction of functional plant belts does not interfere with the normal production management of a medlar garden, and rotary tillage and soil raking are carried out on the plant belt soil before sowing. In the method, the functional plant cultivation belt is used for soil rotary tillage before sowing, and the depth can be 20-30 cm. In the method, in the step 2), the functional plant seeds establish a echelon sowing quantity standard according to the particle size of the seeds and the field seedling density requirement, wherein the particle size of the seeds is calculated by thousand grain weight, When the functional plant seeds are astragalus (Astragalus membranaceus), the seed particle size can be more than 6g, and the sowing quantity can be 5.0-6.0 kg/mu; When the functional plant seeds are baikal skullcap root (Scutellaria baicalensis), the particle size of the seeds can be 2-3 g, and the sowing amount can be 4.0-5.0 kg/mu; when the functional plant seeds are starwort (STELLARIA DICHOTOMA), the seed particle size can be less than 1.5g, and the sowing amount can be 3.0-4.0 kg/mu. In the method, the functional plant seeds are sowed in a drill mode, the row spacing can be 20-30 cm, and the sowing depth can be 1.0-2.0 cm. In the method, in the step 2), mechanical compacting is performed after sowing; The mechanical compacting adopts a compacting rolle
