Abstract

The invention discloses a foliar fertilizer which comprises the following raw materials in parts by weight: 23-25 parts of phosphoric acid, 18-22 parts of a calcium additive, 15-25 parts of an N-K modifier, 5-7 parts of sulfur, 11-13 parts of a zinc additive, 1-3 parts of trace elements and 3-6 parts of a humic acid promoter. The product can promote fruit growth and improve fruit products and fruit nutrient elements; in the added raw material components, manganese is beneficial to synthesis of chlorophyll, and iron is necessary for photosynthesis and is also used for plant respiration and improvement of flowering and fruiting rates; molybdenum contributes to development of pigments, and boron can assist absorption and transfer of calcium, so that differentiation and growth of root tissues are realized, and the fruit growing efficiency is improved; through cooperation of N, K, P and S, fruit growth of the product and synthesis of chlorophyll are further promoted; through the cooperation of the N-K modifier and the humic acid promoter, the growth of the fruits and the content of chlorophyll and nutrient elements can be obviously enhanced.

Description

technical field [0001] The invention relates to the technical field of foliar fertilizers, in particular to a foliar fertilizer and a preparation method thereof. Background technique [0002] Fertilizers refer to substances that can supply nutrients for crop growth and development, improve soil properties, and improve crop yield and quality. It is an important means of production in agricultural production. Generally divided into organic fertilizers, inorganic fertilizers, biological fertilizers. It can also be divided into farm fertilizers and chemical fertilizers according to the source. According to the amount of nutrients contained, it is divided into complete fertilizer and incomplete fertilizer; according to the characteristics of fertilizer supply, it is divided into direct fertilizer and indirect fertilizer; according to the content of nutrients, it is divided into nitrogen fertilizer, potassium fertilizer, trace element fertilizer and rare earth element. fertiliz...
