A rice-wheat rotation farmland ecosystem and cross-season pest control method based on angelica-camellia intercropping enemy containment zone

This invention discloses a rice-wheat rotation farmland ecosystem based on an intercropping natural enemy conservation zone of Angelica sinensis and Osmanthus fragrans, and a cross-seasonal pest control method. The method involves planting Osmanthus fragrans trees at 3-5 meter intervals along field ridges, with Angelica sinensis interspersed among them, thus constructing a perennial natural enemy conservation zone. During the flowering periods of Angelica sinensis (May-June) and Osmanthus fragrans (September-October), volatile compounds are released, providing nectar and pollen to attract natural enemies such as ladybugs, lacewings, hoverflies, and parasitic wasps to colonize and proliferate. These natural enemy populations naturally migrate into the farmland during the wheat and rice seasons to control pests such as wheat aphids, rice planthoppers, and rice stem borers, with significant control effects and reducing pesticide application by 1-2 times. This perennial system is easy to manage and can generate economic benefits from the harvest of Angelica sinensis and Osmanthus fragrans, providing a technical approach for green agriculture in rice-wheat rotation areas.
