Thirdly, the government can provide appropriate market incentives, such as giving "green consumption vouchers" rewards to units or individuals who purchase ecological products, or promoting government canteens and school canteens to prioritize the purchase of ecological rice and rice field duck products to demonstrate and drive consumption. Some people in the industry suggest developing rice-duck co-breeding experiential agriculture and adoption agriculture. For example, urban residents adopt a "duck field" to receive a certain amount of rice and duck meat every year, thereby increasing consumer participation and recognition. As long as consumers are fully aware of the advantages of rice-duck co-breeding products in terms of quality and social value, their market acceptance will naturally gradually increase. It is foreseeable that as people's awareness of health and environmental protection increases, the market demand for green organic agricultural products will continue to expand, and the high-quality rice and ducks bred by rice and duck will also have a broader market space. 6.3 Need for technical standards and policy support In the process of promoting rice-duck co-breeding, perfect technical standards and strong policy support are also indispensable. First of all, there is still a lack of unified technical specifications for rice-duck co-breeding in some areas. Farmers mainly rely on experience, resulting in uneven production results. Therefore, there is an urgent need to standardize the planting and breeding technology system. For example, what kind of ducks are suitable for stocking in which rice growing areas, how to control stocking density and time, what are the requirements for water and fertilizer management and disease prevention and control, etc. Mature experience should be summarized and upgraded to regional technical regulations or industry standards to guide large-scale promotion. Scientific research institutions and extension departments should strengthen collaboration, conduct systematic research on rice-duck co-breeding models in different ecological zones, develop standard manuals and distribute them to farmers through training. Secondly, policy support must keep up. The initial investment in developing rice-duck co-breeding is relatively large, such as purchasing duck-proof facilities, building duck sheds, purchasing duck seedlings, etc., which all require a certain amount of funds. The government can reduce the burden on farmers through project subsidies, loan discounts, etc., and encourage them to adopt ecological farming models. For example, a certain amount of reward per mu will be given in lieu of subsidy to the certified rice-duck co-breeding demonstration base to mobilize the enthusiasm of farmers. In Zhejiang and other places, there are special subsidy policies for comprehensive rice farming, and farmers have responded well. The policy should also include insurance and risk protection measures. Since the introduction of rice-duck co-breeding into the breeding process, natural risks and market risks have increased. The government can explore the pilot program of rice-duck co-breeding insurance and provide compensation for losses caused by natural disasters or epidemics to reduce farmers' concerns. Finally, a collaborative promotion mechanism must be established. Rice-duck co-breeding involves two departments: planting and breeding. In the traditional agricultural management system, the two often belong to different departments (for example, the planting industry belongs to the agricultural technology extension station, and the animal husbandry belongs to the animal husbandry and veterinary station). Therefore, departmental collaboration should be strengthened and a joint technical team should be established to jointly promote the promotion services of rice-duck co-breeding technology (Vipriyanti et al., 2021). Agricultural and rural departments at all levels can organize cross-field expert tours to provide guidance and go to the front line of production during key farming seasons to help farmers solve technical problems. Give full play to the leading role of new business entities and demonstration households, and establish a number of rice-duck co-breeding demonstration areas so that surrounding farmers can visit and learn on the spot and enhance their confidence in the model. Through a "two-pronged approach" of technical standardization and policy support, the rice-duck co-breeding model is expected to accelerate from sporadic exploration to large-scale promotion, forming a sound development situation with government guidance, expert support, and farmer participation. 7 Concluding Remarks As a modern ecological agricultural model, rice-duck symbiotic farming is of great significance to the current
