Abstract

The invention discloses a high-potassium multi-element foliage fertilizer and a preparation method thereof. The foliage fertilizer mainly comprises raw materials which are rich in trace elements such as nitrogen, phosphorus, potassium, iron, manganese, boron and magnesium, and is prepared by mixing potassium nitrate, monopotassium phosphate, anhydrous magnesium sulfate, disodium octaborate tetrahydrate, EDTA (Ethylene Diamine Tetraacetic Acid) zinc, EDTA iron, EDTA copper, EDTA manganese, molybdic acid amine, citric acid, sodium citrate, EDTA-2Na and sodium tripolyphosphate in a certain ratio. In the preparation method, monopotassium phosphate and potassium nitrate are taken as main raw materials, so that a water-soluble foliage fertilizer in which potassium is taken as a major material, nitrogen and phosphorus are taken as auxiliary materials, and a plurality of EDTAs are chelated with trace elements simultaneously is produced. In the presence of a chelate and the trace elements, full absorption of elements is facilitated, the metabolism of crops is promoted, photosynthesis is enhanced, the formation of chlorophyll is facilitated, actions among various substances can be coordinated, the growth of the crops is facilitated, the fruit quality is improved, and the self-resistance of plants is enhanced.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a high-potassium type multi-element foliage fertilizer and a preparation method thereof. Background technique [0002] Potassium plays an important role in the growth and development of plants. Its main function is that when an appropriate amount of potassium exists, plant enzymes can fully exert their effects. Potassium can promote photosynthesis. Some data show that leaves with high potassium content convert 50%-70% more light energy than leaves with low potassium content. Therefore, under the condition of poor light, the effect of potassium fertilizer is more significant. In addition, potassium can also promote the metabolism of carbohydrates, promote the metabolism of nitrogen, enable plants to use water economically and effectively and improve plant resistance. Potassium can promote the synthesis of cellulose and lignin, so that the plant stems are thick a...
