A kind of fertilization of nano silicon magnesium potassium flushing and preparation method thereof

Abstract

The invention discloses a nano silicon-magnesium-potassium water flush fertilizer. The prepared nano silicon-magnesium-potassium water flush fertilizer is prepared from the following materials in percentage by mass: 65%-70% of nano silicon-magnesium powder, 10%-15% of potassium sulfate, 5%-10% of potassium humate, 5%-10% of nano medical stone powder, 1%-2% of carboxymethyl modified starch, wherein the sum of the materials in percentage by weight is 100%. The preparation method comprises the following steps of: preparing magnesium ore slag and medical stone into nanoscale particle fine powder; adding the potassium sulfate, the potassium humate and the carboxymethyl modified starch according to the proportion of the formula, sufficiently and uniformly stirring with water to form paste; and checking, filling, metering, sealing and labeling to obtain the nano silicon-magnesium-potassium water flush fertilizer. The nano silicon-magnesium-potassium water flush fertilizer is low in production cost, good in stability and suitable for industrial production. A field system test indicates that the nano silicon-magnesium-potassium water flush fertilizer has complete functions, gathering nutrients, and a long fertilizer efficiency period, and enables crops including wheat, corns, rice, melons, fruits, vegetables, apples, oranges, grapes, cottons and the like to increase yield.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizer research, and relates to a nano-mineral fertilizer, in particular to a nano-silicon-magnesium-potassium flushing fertilization and a preparation method thereof. The main component of the nano-silicon-magnesium-potassium flushing fertilization prepared by the invention is magnesium, which is waste after industrial magnesium production. Slag, which contains high-efficiency plant nutrients, can improve soil, increase plant nutrition, resist diseases, increase yield, improve the quality and efficacy of agricultural products. Background technique [0002] With the sharp increase in the consumption of metal materials, the resources of the earth's surface shell are becoming increasingly depleted, and many traditional metal minerals are tending to be exhausted. Accelerating the development of magnesium metal materials is one of the important measures for the sustainable development of society. Due t...
