Method for growing plants by using space waste and wastewater

The invention relates to a method for growing plants by using space waste and wastewater. According to the method, wheat straws are used as the main raw material of the space waste, the waste is subject to pretreatment, fermentation by added microbial inoculums and through-decomposing treatment, is mixed with vermiculite according to a ratio of 1:1 to be a soil substrate and is used as a plant growing substrate; the analog space wastewater is used as the main raw material of the wastewater, the wastewater is subject to primary deposition, filtering by a zeolite layer, foamless oxygen supply micro-organism treatment, and the like, is mixed with tap water and Hoagland full-nutrient solution according to a ratio of 1:1:2 to be plant nutrient solution. According to the method, the technique condition of using analog wastewater and waste renewable resources for plants is researched on the basis of using the method of waste and wastewater renewable resources recycling method in agricultural and industrial productions for reference and according to the characteristics of a sealed ecosystem, so that an excellent solving way is provided for performing plant growing in a controlled ecological life support system under a space condition by using renewable resources, and improving the closure of the system.
