介绍目前我国水溶肥现状。研究水溶肥不同稀释倍数对芹菜和西红柿产量的影响。指出当前水溶肥在使用过程中普遍采用的2种精准稀释方法存在不便捷,投入大或具有局限性等问题。使用颜色随p H变化的变色水溶肥,可通过直观的颜色变化达到精准稀释的目的,在作物增产和肥料防伪方面效果独到。
Present situation of water soluble fertilizer in our country. The effects of different dilutions of water-soluble fertilizer on the yield of celery and tomato were studied. It is pointed out that the two kinds of precision dilution methods widely used in the process of using water-soluble fertilizer are inconvenient, expensive or have limitations. The use of color-changing water-soluble fertilizer whose color changes with p H achieves the goal of precise dilution by an intuitive color change and is unique in terms of crop yield and fertilizer anti-counterfeiting.
