Description

Technical Field

[0001] The invention relates to the field of agricultural pest prevention, and in particular to an application technology of a remote irrigation system combined with calendula to prevent and control wheat aphids in wheat fields. Background Art

[0002] As one of the most important food crops in the world, wheat production and quality are directly related to global food security and the stable development of the agricultural economy. However, in the process of wheat cultivation, wheat aphids, as a common pest, pose a serious threat to wheat growth. Wheat aphids mainly feed on the sap of wheat leaves and stems, which leads to stunted wheat growth and reduced yields. In severe cases, wheat harvest failure may even occur. Therefore, the prevention and control of wheat aphids has always been an important topic in the field of agricultural technology.

[0003] Traditional methods of wheat aphid control mainly rely on chemical pesticides. Although these pesticides can kill pests quickly in the short term, long-term use brings many problems. On the one hand, chemical pesticides can easily cause pests to develop resistance, resulting in a gradual weakening of the control effect; on the other hand, the large-scale use of chemical pesticides will damage the farmland ecosystem, affect biodiversity, and may even pose a potential threat to human health through the food chain. Therefore, it is particularly important to explore an environmentally friendly, efficient and sustainable method for wheat aphid control.

[0004] In recent years, with the continuous advancement of agricultural technology and the improvement of people's environmental awareness, green control technologies such as biological control and physical control have gradually received attention. Among them, the use of interactions between plants for biological control is a potential method. As a common ornamental plant, calendula not only has a beautiful appearance, but also has certain biological activity. Studies have shown that calendula can release specific volatile substances, which have a repelling or inhibitory effect on certain pests, and can also attract the natural enemies of pests, thereby building a natural biological control system.

[0005] However, there are still some challenges in applying calendula to control wheat aphids in wheat fields. How to reasonably arrange calendula so that it can fully play its role in biological control; how to ensure the healthy growth of calendula in wheat fields to maintain its biological activity; and how to combine modern irrigation technology to achieve precise irrigation and green control of wheat fields are all urgent issues to be solved.

[0006] In order to solve the above problems, the applicant proposed an application technology of a remote irrigation system combined with calendula to prevent and control wheat aphids in wheat fields. Summary of the invention

[0007] The purpose of the present invention is to provide an application technology of a remote irrigation system combined with calendula to prevent and control wheat aphids in wheat fields, so as to solve the problems in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solutions: 1. An application technology of a remote irrigation system combined with calendula to prevent and control wheat aphids in wheat fields, characterized in that it includes:

[0009] Remote irrigation system for real-time monitoring of soil temperature and humidity in wheat fields. The system uses mobile phone software for real-time monitoring, and the drip irrigation pipes of the irrigation system are installed on the marigold belt to achieve precise irrigation of the wheat fields;

[0010] The planting layout of marigolds is to plant 3 rows of marigolds every 20 meters in the center of the wheat field, using the biological characteristics of marigolds to naturally prevent and control wheat aphids.

[0011] Optionally, the planting technical details of the calendula include: selecting calendula varieties suitable for local climate and soil conditions, and planting them according to a predetermined planting density and row spacing.

[0012] Optionally, the remote irrigation system also includes soil environment monitoring equipment for real-time monitoring of the soil environment in the field, timely adjusting the irrigation plan according to the monitoring results, and timely irrigation in the dry season to reduce labor costs.

[0013] Optionally, after adopting this technology, the occurrence of wheat aphids in wheat fields is significantly reduced, while the number of natural enemies that feed on aphids increases. The occurrence of natural enemies such as ladybugs and aphids is significantly higher than that of the treatments without control and normal control, and the occurrence of aphid flies is also significantly higher than that of normal control.

[0014] Optionally, after adopting this technology, the use of chemical pesticides in wheat fields is reduced by 50%. In the conventional prevention and control process, the application of pesticides such as seed dressing, spraying of imidacloprid during the greening and jointing period, and heading period is reduced by half. Specifically, when using 33% chlorofluoroimidacloprid suspension, the amount of medicine per hectare is reduced to 270mL from the conventional amount, and diluted with water to 450L for spraying.

[0015] Optionally, the use of this technology can also improve the ecological landscape and environment of farmland, increase the biodiversity of farmland, and promote the healthy and stable development of farmland ecosystems.

[0016] Beneficial effects: 1. Significantly reduce the occurrence of aphids:

[0017] Through this patented technology, three rows of marigolds are planted every 20 meters in the center of the wheat field, using the biological characteristics of marigolds to attract and reduce the number of wheat aphids. This biological control method is not only effective, but also environmentally friendly and avoids the excessive use of chemical pesticides.

[0018] 2. Increase the number of natural enemies and promote ecological balance:

[0019] The planting of marigolds also promotes the reproduction and habitat of natural enemies such as ladybugs, parasitic wasps and syrphid flies, which can further control the number of aphids, thus forming a virtuous cycle of the ecosystem. Compared with the treatments of no control and normal control, the number of natural enemies increased significantly, which helps to maintain the ecological balance of the wheat field.

[0020] 3. Reduce the use of chemical pesticides and reduce environmental pollution:

[0021] After adopting this patented technology, the use of chemical pesticides can be reduced by 50%. In the process of conventional prevention and control, the significant reduction in the amount of pesticides used helps to reduce pesticide residues and environmental pollution, and also helps to protect the ecological safety of soil and water resources.

[0022] 4. Improve farmland ecological landscape and environment:

[0023] The cultivation of calendula not only has the function of preventing and controlling aphids, but also can beautify the farmland environment and enhance the ecological landscape value of the farmland. This is of great significance for promoting sustainable agricultural development and ecotourism.

[0024] 5. Real-time monitoring of soil environment to reduce labor costs:

[0025] This patented technology is also combined with a remote irrigation system that can monitor the soil temperature and humidity in the wheat field in real time. This intelligent irrigation method not only improves irrigation efficiency, but also allows timely irrigation during dry seasons, thereby reducing labor costs. At the same time, the monitoring equipment can also provide accurate soil environmental data, providing a scientific basis for farmland management. BRIEF DESCRIPTION OF THE DRAWINGS
