4. In addition to acetic acid, vinegar has various nutrients such as amino acids, succinic acid, lactic acid and glycerin. When vinegar is sprayed on the vegetable leaf surface, these nutrients are absorbed by the leaves, which can increase the nutrients inside the plant, accelerate the formation of chlorophyll, and improve the photosynthesis of cucumber, thereby improving the quality and characteristics of cucumber.
