The invention relates to a method for synthesizing copper-based perovskite powder by a low-temperature solvent method. The method comprises the following steps: adding CsX and CuX into a polar organicmixed solution, and stirring for 4-6 hours at 40-70 DEG C, wherein the polar organic mixed solution is a mixed solution of N, N-dimethylformamide (DMF)and dimethyl sulfoxide (DMSO), the CsX is cesiumchloride, cesium bromide or cesium iodide, and the CuX is copper chloride, copper bromide or copper iodide. According to the synthesis process, constant-temperature growth on a hot plate is not needed, synthesis is directly conducted on a magnetic stirrer, the synthesis process has the advantages of being short in manufacturing period, low in cost, simple in growth step, environmentally friendlyand the like, and Cs3Cu2X5 powder with high crystallization quality is separated out within 5 hours.

The invention discloses a brewing method of mockstrawberry fruit wine. The brewing method is characterized by being prepared through the steps of taking mockstrawberry fruits as the raw material, pre-treating, enzymatic hydrolysis, blending, activation of yeast, fermenting, mixing, ageing, clarifying and filtering, filling and sterilizing and other steps. According to the brewing method of mockstrawberry fruit wine, mockstrawberry fruits are placed into high-concentration Baijiu for soaking after being diced, loss of nutritive materials is avoided, the soaked mockstrawberry fruits are pulped and then subjected to compound enzyme treatment, precipitation of more nutritive materials of the mockstrawberry fruits is facilitated, the utilization efficiency of mockstrawberry fruits is improved, a compound clarifying agent is adopted for clarification treatment after ageing, therefore the finished mockstrawberry fruit wine is stable in color and luster, transparent in wine body, soft in taste, and has health care effects of reducing sputa to relieve cough, expelling the wind, promoting blood circulation, relieving swelling, stopping pain and improving immunity.
