Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of pest control, and particularly relates to a method for cultivating and multiplying predatory natural enemy insects in a navel orange orchard. Background Art
[0002] Gannan navel orange is a national geographical indication product in China, and its cultivation is troubled by various pests and diseases. The main disease of navel orange is citrus huanglongbing, and the field transmission vector is Diaphorina citri. In addition, the pests also include aphids, whiteflies, thrips, leafminers, fruit flies, and spider mites (pest mites), etc. At present, the control of pests mainly relies on chemical agents, but chemical pesticides will cause a series of problems such as a large number of deaths of natural enemy insects in citrus orchards, loss of biodiversity, different degrees of resistance of pests, and excessive pesticide residues in fruits. Biological control has the advantages of being green and environmentally friendly, and biological control has become a pest control method with great application prospects for citrus pests. The biological control resources mainly include natural enemy insect resources and pathogenic fungal resources. Among them, the predatory natural enemy species are rich, including multiple groups such as ladybugs, lacewings, predatory mites, spiders, ants, and mantises, but the dominant group is predatory ladybugs. At present, the technology for producing natural enemy products such as ladybug egg cards is relatively mature, and biological control can be carried out by releasing natural enemies in the orchard. However, the natural enemies released in the short term often decrease sharply due to the reduction of the target pest population and the lack of shelters, resulting in a lack of continuous effect in natural enemy control. Creating a suitable shelter for natural enemies in the navel orange orchard is an urgent problem to be solved.
[0003] In the ecological regulation process of pests, functional plants usually have the functions of providing "clothes (pollination service), food (food service), housing (shelter service), and transportation (transfer service)" for beneficial arthropods (natural enemies and pollinating insects), and do not provide functions for the pests on the target protected crops. Functional plants include nectar plants, habitat plants, reservoir plants, and trap plants, etc. Planting nectar plants in the navel orange orchard to form a complex and diverse navel orange orchard ecosystem. On the one hand, the pests or pollen growing on the nectar plants can provide food for predatory natural enemies. On the other hand, it can provide a shelter for the natural enemies in the navel orange orchard. When pesticides are applied and the pests on the navel orange trees decrease, the natural enemies can inhabit, and when fruit tree pests occur, the natural enemies can transfer to feed on the pests. Therefore, improving the mutual relationship between pests and natural enemies in the orchard by constructing a coexisting complex ecosystem of navel orange orchard-nectar plants and fully enhancing the control effect of natural enemies on navel orange pests is the key technical measure for sustainable biological control.
[0004] Although there are currently many nectar-source functional plants being studied, most of them are based on farmland ecosystems such as wheat and rice planting areas, as well as northern orchard ecosystems such as apple orchards and pear orchards. However, the navel orange planting area is located in the southern region, where there are a large number of pest species. Selecting functional plants that are beneficial to natural enemies but not to pests is the prerequisite for ecological pest control. Moreover, the selected functional plants should have the characteristics of being economically efficient and suitable for planting in navel orange orchards. Therefore, the primary issue becomes which nectar-source plants to plant in navel orange orchards and how to plant them. Summary of the Invention

[0030] To further illustrate the present invention, the following describes in detail a method for conserving and proliferating predatory natural enemy insects in a navel orange orchard provided by the present invention in combination with embodiments, but they cannot be understood as limiting the protection scope of the present invention.
[0031] Unless otherwise specified, the present invention has no special requirements for the preparation raw materials, and commercially available products well-known to those skilled in the art can be used.
[0032] Selection of the test site of the present invention: From 2023 to 2024, honey source plants were planted in the navel orange orchard in Anxi Town, Xinfeng County, Jiangxi Province. The navel orange variety is Newhall. This mainly includes mountainous and hilly areas and is one of the main planting areas of navel oranges in southern Jiangxi. Selecting this place for pest ecological prevention and control research is representative.
[0033] Example 1
[0034] Autumn seed sowing (mid-late November): When the navel oranges are harvested, select an orchard with sufficient watering conditions. Select the side far from the fruit trees in the strip as the Cnidium monnieri planting area. The width of the planting area is 60 cm. Apply base fertilizer to the area where Cnidium monnieri is to be planted, and use a rotary tiller to till and loosen the soil (the tilling depth is 20 cm) to ensure soil fertility. Soak the Cnidium monnieri seeds in clear water. After soaking for 24 hours, mix the soaked Cnidium monnieri seeds with soil in a volume ratio of 1:1, and evenly spread the mixed Cnidium monnieri seeds into the strip and slightly cover the soil (the thickness of the covered soil is less than 1 cm). Appropriate shading can be carried out with a strip-shaped sunshade cloth to prevent the sun from drying the soil and high temperature. The seeding rate per mu is 1.5 kg. After sowing, spray irrigation is carried out to make the entire Cnidium monnieri planting belt completely wet. Due to the continuous drought in autumn and winter in southern Jiangxi, the planting belt needs to be regularly irrigated to keep the soil moist until the seeds germinate, and then appropriate watering can be carried out according to the soil moisture content (the soil water content is not less than 50%) until spring rainfall.
[0035] Example 2
[0036] Transplant the seedlings after raising them in autumn (November): This method is recommended. In November, plant the Cnidium monnieri seeds in plug trays indoors. Before placing the seeds, water the substrate nutrient soil until it is thoroughly wet. Place 8 seeds in each hole, then cover with a thin layer of substrate nutrient soil (the thickness of the substrate nutrient soil is less than 1 cm), and spray it wet with a watering can. Place the plug tray in a plug tray cart that can hold water, and add clear water to the cart to keep the substrate nutrient soil constantly moist. Transplant it into the strip when the rainy season comes in February. Apply basal fertilizer to the strip before transplanting, and use a rotary tiller to till the soil. The width of the transplanting area is 40 cm.
[0037] The substrate nutrient soil is composed of: humus soil, peat soil, perlite and vermiculite (volume ratio is 4:2:1:1).
[0038] Example 3
[0039] Sow the seeds in spring (March): Select an orchard with sufficient watering conditions, and choose the side away from the fruit trees in the strip as the Cnidium monnieri planting area. The width of the planting area is 50 cm. Apply basal fertilizer to the area where Cnidium monnieri is to be planted, and use a rotary tiller to loosen the soil (the depth of tilling is 25 cm) to ensure soil fertility. Soak the Cnidium monnieri seeds in clear water. After soaking for 26 hours, mix the soaked Cnidium monnieri seeds with soil in a volume ratio of 1:1, and evenly spread the mixed Cnidium monnieri seeds into the strip and slightly cover with soil (the thickness of the soil cover is less than 1 cm). Appropriate shading can be carried out with a strip-shaped sunshade cloth to prevent the sun from drying the soil and high temperature. The seeding rate per mu is 1.3 kg. After sowing until the seeds germinate, appropriate watering can be carried out according to the rainfall and soil moisture (the soil water content is not less than 50%).
[0040] Experimental example
[0041] On the basis of the above embodiments, the present invention conducts a field natural enemy conservation and proliferation experiment by the method provided in Example 1, and synchronously conducts multiple control experiments, with the increase ratio of the number of predatory natural enemies on navel orange trees and the decrease ratio of the number of citrus aphids and citrus psyllids as the comparison criteria;
[0042] Control experiment 1: The same as Example 1, except that the natural enemy conservation plant to be planted is changed to rape. Rape needs to complete sowing and seedling raising before mid-October and complete field transplantation before mid-November. The transplanting width is the same as that in Example 1, and the subsequent management is the same as that in Example 1.
[0043] Control experiment 2: The same as Example 1, except that the natural enemy conservation plant to be planted is changed to cosmos. Plant it in early March, and the planting width is the same as that in Example 1. The subsequent management is the same as that in Example 1.
[0044] Control experiment 3: Same as Example 1, except that the natural enemy-harvesting plant was changed to Ageratum cochinchinensis, planted in early March, the planting width was the same as in Example 1, and the subsequent management was the same as in Example 1.
[0045] Control experiment 4: In the control area, no functional plants were planted. In the control area, weeds and other plants on the ground of the orchard were regularly cleaned up to keep the ground free of weeds.
[0046] The strips planted with Cnidium monnieri, rapeseed, Autumn sedge and Ageratum cochinchinensis were the grass cultivation functional areas. The functional plant planting areas were weeded regularly to keep the experimental areas free of weeds. The agricultural operations and management methods of the functional areas and the control areas were the same.
[0047] During the flowering period of nectar plants, natural enemies and pests on navel orange trees were investigated. Natural enemies mainly refer to ladybugs and lacewings, and pests refer to citrus aphids and citrus psyllids. The specific investigation method is: select 3 strips in the functional area and the control area, investigate the navel orange trees in the middle of each strip, and observe whether there are relatively large insects on the crown at the beginning of the investigation. Then divide the east, south, west and north of each tree crown into 4 investigation units, select a branch in each investigation unit, and select 50cm branches from the top to investigate the types and number of natural enemies. The new shoots should be carefully searched and counted, and the population of natural enemies and pests on the navel orange trees should be counted. The results showed that Cnidium monnieri can grow in navel orange orchards in southern Jiangxi. By planting nectar plants such as Cnidium monnieri and rapeseed, the number of predatory natural enemies increased by 11.76% to 91.18% (Table 1), the population of citrus aphids decreased by 6.69% to 43.76%, and the population of citrus psyllids decreased by 5.04% to 40.31% during the flowering period of nectar plants compared with the blank control area. The conservation and proliferation effect of Cnidium monnieri on predatory natural enemies far exceeded that of rapeseed, autumn gentian and ageratum, and the control effect of its natural enemies on aphids and psyllids was also better than that of the other three nectar functional plants. The results showed that by planting Cnidium monnieri in navel orange orchards, the composite ecosystem formed in the orchard had a significant conservation and proliferation effect on predatory natural enemies. Natural enemies could be transferred to navel orange trees to prey on navel orange pests, reducing the number of pest populations, providing a basis for reducing the use of pesticides, and was an effective technical measure for implementing green control of navel orange pests, with significant economic, social and ecological benefits.
