在甜瓜上进行水溶性肥料的应用效果试验。结果表明，相同基肥条件下，追施水溶肥能增加甜瓜产量，结瓜数平均增加14.8%，单瓜重增加5.5%。基本相同养分投入条件下，追施水溶肥比追施复合肥处理亩产甜瓜增加3.4%，但差异不显著；水溶型配方肥处理经济效益更好，施用水溶肥比复合肥能增加纯收益2.6%，水溶肥每公斤纯养分平均产出14.1公斤，比普通平衡配方型复合肥处理高出15.5%。
The effect of water-soluble fertilizer on melon was tested. The results showed that the yield of muskmelon could be increased by applying water-soluble fertilizer after the same basal fertilizer. The average number of melons increased by 14.8%, and the single melon weight increased by 5.5%. Under the condition of the same nutrient input, the yield of melon increased by 3.4% with the application of water-soluble fertilizer, but the difference was not significant; the economic benefit of water-soluble formula fertilizer was better than that of compound fertilizer. The net income of water-soluble fertilizer was 2.6% higher than that of compound fertilizer. The average output of water-soluble fertilizer per kilogram of pure nutrient was 14.1 kg, which was 15.5% higher than that of common balanced formula compound fertilizer.
