8. equipment investment

Eight rice and fishery demonstration areas with a total area of 400 hectares have been established in eight countries including Indonesia, the Philippines, Laos, Myanmar, Cambodia, Uganda, Nigeria, and Sierra Leone. Equipment investment: 24 million yuan. Main purpose: It is used to pay the rental fees of engineering equipment such as excavators and the purchase fees of production auxiliary equipment such as water and electricity in the renovation and construction project of the comprehensive planting and breeding system. Estimation basis: The rental fee for engineering equipment such as excavators is 2000 yuan/mu, the purchase fee for production auxiliary equipment such as water and electricity is 2000 yuan/mu, and the total investment in equipment per mu is 4000 yuan. Taking the rice and fishery demonstration area with a construction area of 400 hectares as an example, the total equipment investment is 4000 yuan/mu ×400 hectares ×15 acres/hectare = 24 million yuan. Technical life: 5-10 years.

9. Annual operation and maintenance fee

Main purpose: Used to pay for production, operation and maintenance expenses such as seedlings, fish species, shrimp seedlings, feed, water and electricity, labor, equipment, maintenance and management. Estimation basis: The more suitable models for Africa and ASEAN countries are rice fish (tilapia) model and rice shrimp (Macrobrachium rosenbergii) model. Under the two models, seedlings, feed, water and electricity, labor, equipment, maintenance and management, etc. The related costs are approximately 1500 yuan/mu and 2000 yuan/mu. Taking the rice fishery demonstration area with a construction area of 400 hectares as an example, the rice fish model (African countries) and rice shrimp model (ASEAN countries) have 200 hectares respectively. Total operation and maintenance costs =(1500+2000) yuan/mu ×200 hectares ×15 acres/ha = 10.5 million yuan.

10. investment recovery period

Investment payback period: 1 year. Calculation basis: Take the rice fish (tilapia) model and the rice shrimp (Macrobrachium rosenbergii) model as examples. In the rice-fish (tilapia) model, the average comprehensive output value per mu is 6500 yuan/mu. After deducting the equipment fee of 4000 yuan/mu and the operation and maintenance fee of 1500 yuan/mu, the average net income per mu that year is 1000 yuan; In the rice shrimp (Macrobrachium rosenbergii) model, the comprehensive output value is 9400 yuan/mu. After deducting the equipment fee of 4000 yuan/mu and the operation and maintenance fee of 2000 yuan/mu, the average net income per mu that year is 3400 yuan. Therefore, the actual investment return period for both models is 1 year.

11. added benefit

New output value: 35.7 million yuan. Calculation basis: Simply growing rice: The average rice yield per mu is 600-650 kilograms, with a unit price of 3 yuan/kg, and the output value is about 2000 yuan/mu; the rice fish (tilapia) model has an average rice yield of 450 kilograms, with a unit price of 10 yuan/kg, and the fish yield is 100 kilograms, with a unit price of 20 yuan/kg, and a comprehensive output value of 6500 yuan/mu; the rice shrimp (Macrobrachium rosenbergii) model has an average rice yield of 400 kilograms, with a unit price of 16 yuan/kg, and a shrimp yield of 60 kilograms, with a unit price of 50 yuan/kg, and a comprehensive output value of 9400 yuan/mu. Therefore, the increase in average output value per mu of rice-fish model = 6,500 - 2,000 yuan =4500 yuan; the increase in average output value per mu of rice-shrimp model = 9,400 - 2,000 yuan =7400 yuan. Taking the rice fishery demonstration area with a construction area of 400 hectares as an example, the rice fish model (African countries) and rice shrimp model (ASEAN countries) have 200 hectares respectively. Increase in total output value =(4500+7400) yuan/mu ×200 hectares ×15 acres/hectare = 35.7 million yuan. While increasing output value, by providing innovative technologies and breeding models, we support the transformation of traditional aquaculture industry to green and climate-smart rice and fishery green comprehensive planting and breeding technology to achieve energy conservation and emission reduction to mitigate global climate change, protect the ecological environment and biodiversity. Sex, ensure food security and nutrition supply, improve rural life, and improve environmental benefits.

12. comprehensive benefits

Compared with traditional planting and breeding methods, great innovations have been made in the green comprehensive planting and breeding technology of rice and fishery. Compared with traditional rice field breeding, in the rice and fishery green breeding system, materials circulate in a virtuous manner on the spot, and energy flows in a favorable direction for both rice and fish (shrimp, crab, turtle, and loach). Weeds and pests in the rice fields provide food for fish, while the growth of rice purifies water quality, thus forming a rice-fish mutually-beneficial symbiotic ecosystem, effectively improving the utilization efficiency of water resources, and solving the problem of pollution of water and soil resources within the system. The protection and restoration of cultivated land resources are of far-reaching significance. The comprehensive rice and fishery planting and breeding technology has formed a new circular agriculture development model with obvious characteristics of "one water for multiple uses, one field for multiple harvests, and multiple effects". It covers all levels of ecosystems of mountains, rivers, forests, fields, lakes and grass, and effectively solves the problems of land use and protection such as the interaction and circulation of multiple elements of water, soil and gas in the system are of far-reaching significance for the restoration of natural resource ecosystems. According to yield measurement data from multiple core demonstration sites of the center in Yunnan, Sichuan, Chongqing, Hubei, Jiangsu and other places, the rice yield per mu of the demonstration sites is stable at 300 kg-650 kg, with an average increase in production by 5%-15%. The average yield of aquatic products is 50 kg-120 kg, the use of inputs such as chemical fertilizers, pesticides, and fishery drugs is reduced by 50-100%, nitrogen and phosphorus emission reductions are achieved by 19%-75%, and economic benefits are increased by 11%-75%. Comprehensive rice and fishery planting and breeding technology meets the sustainable development needs of the "Belt and Road" countries, and has obvious comprehensive benefits.

More than 200 new business entities such as professional cooperatives and leading enterprises have been cultivated in the demonstration area, and 30 rice brands and 21 aquatic products brands have been created. The rice output in the demonstration area has stabilized at more than 500 kilograms, and the rice fields have increased the efficiency by more than 50%. The amount of pesticides used has been reduced by an average of 51.7%, the amount of chemical fertilizers has been reduced by an average of more than 50%, and the efficiency per mu has been increased by more than 1000 yuan. What is more noteworthy is that while the total area of freshwater aquaculture has been reduced by 0.59%, the area of fish farming in rice fields in 2019 increased by 14.26% compared with 2018, or approximately 289,200 hm2. Therefore, the comprehensive rice and fishery breeding technology system has high maturity.

15. technical applicability

Based on the implementation foundation and survey data of the center's "Belt and Road" national cooperation project in ASEAN and African countries, the "rice-fishery co-farming" technology can be quickly implemented and marketed in countries in ASEAN and Africa with rich water and heat conditions and rice field resources. Promote, because this technology not only conforms to local agricultural policies and environmental protection laws and regulations, but also serves as a "double guarantee" for the supply of grain and high-quality aquatic protein, solving hunger, poverty, Provide technical experience on issues such as malnutrition. Preliminary plans have been made for eight countries in Indonesia, the Philippines, Laos, Myanmar, Cambodia and Uganda, Nigeria and Sierra Leone in Africa.
