Polystyrene (PS) is one of the major plastics contributing to environmental pollution with its durability and resistance to natural biodegradation. Recent research showed that mealworms (Tenebrio molitor) and superworms (Zophobas morio) are naturally able to consume PS as a carbon food source and degrade them without observable toxic effects. In this study, we explored the effects of possible food additives and use of worm frass as potential plant fertilizers. We found that small amounts of sucrose and bran increased PS consumption and that the worm frass alone could support dragon fruit cacti (Hylocereus undatus) growth, with superworm frass in particular, supporting better growth and rooting than mealworm frass and control media over a fortnight. As known fish and poultry feed, these findings present worms as a natural solution to simultaneously tackle both the global plastic problem and urban farming issue in a zero-waste sustainable bioremediation cycle.

Ecological civilization construction and rural revitalization is a strategic decision made by the central government to solve the problems of ecological protection and rural sustainable poverty alleviation. At present, the dominant agricultural operation modes in China can be roughly divided into three types: family farm mode, agricultural enterprise mode and cooperative mode. Practice has proved that different agricultural operation modes have different effects. In ecological fragile areas, how to adopt agricultural operation modes can not only promote agricultural prosperity and increase farmers' income, but also protect the ecological environment and promote the coordinated development of ecology and economy needs further analysis. Based on the current rural revitalization strategy and ecological protection background, this paper analyzes the operation mechanism of agricultural operation mode from the principal-agent and ecological land rent theory, and analyzes the development dimensions of advantageous agriculture of various modes. On the basis of rural and farmers, this paper provides references for the selection of agricultural operation mode in different regions. There are many factors that need to be considered in the choice of agricultural operation mode in ecological fragile area. In the future, each region should conduct analysis and treatment according to its own actual situation.
