The invention discloses a spraying nutrient solution for planting tomatoes. The spraying nutrient solution is prepared by a preparation method comprising the following steps: 1) treating raw materials: mixing fresh passion fruits and tomatoes; adding pure water with weight which is the same as that of the raw materials; crushing and adding pure water with the weight which is 8 to 10 times as much as that of the raw materials; carrying out subcritical water extraction, wherein extraction temperature is 135 DEG C, extraction time is 25min and pressure is 5MPa; 2) clarifying and filtering: separating extraction dreg from a material obtained by step 1) to obtain an extraction solution; standing until the extraction solution is clarified; taking supernatant and filtering to obtain the spraying nutrient solution for planting the tomatoes. 本发明公开了西红柿种植喷施营养液，通过以下制备方法得到：1)原料处理：将新鲜的百香果、西红柿混合，先加入和原料等重的纯净水，打碎，再加入相当于原料8-10倍重量的纯净水，进行亚临界水提取，提取温度135℃，提取时间25min,压力5MPa；2)澄清、过滤：将步骤1)得到物料分离提取渣，得到提取液，放置澄清，取上清液过滤，得到西红柿种植喷施营养液。
