Abstract

The invention discloses a leaf fertilizer containing organic acid. The pipecolic acid composition contains pipecolic acid or malic acid. The invention discloses the application of pipecolic acid or malic acid in increasing vitamin C content and soluble solid content in fruits and vegetables or increasing vegetable yield. On the basis of the basic formula of the compound foliar fertilizer, by adding pipecolic acid or malic acid, the inherent quality of fruits and vegetables can be obviously improved, for example, the content of soluble solids and vitamin C is increased, the yield is increased, and therefore the compound foliar fertilizer can be used for fruit and vegetable production.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a foliar fertilizer containing organic acids. Background technique: [0002] Foliar fertilizers can be divided into 4 categories according to their mode of action, namely: nutritional foliar fertilizers, regulating foliar fertilizers, biological foliar fertilizers, and compound foliar fertilizers. Among them, there are many kinds of compound foliar fertilizers and various mixing forms. Its function is to provide nutrients and stimulate crop growth and development. The application of these different types of foliar fertilizers in agricultural production has different degrees of quality-enhancing and efficiency-enhancing effects, but the increase in yield generally does not exceed 10%, and the quality improvement effect is also unstable. Invention content: [0003] The first object of the present invention is to provide the application of pipecolic acid in inc...
