Compound mixed silicon fertilizer and production method thereof

Abstract

The invention relates to a compound mixed silicon fertilizer and a production method thereof. The compound mixed silicon fertilizer comprises 65-75 wt% of a standard silicon fertilizer, 8-12 wt% of humic acid, 10-15 wt% of L-amino acid and 6-8 wt% of potassium fulvate, and the fineness of the standard silicon fertilizer allows 90% or above of the standard silicon fertilizer to pass through a 125 [mu]m standard sieve. The production method of the compound mixed silicon fertilizer comprises the following steps: all the materials in the compound mixed silicon fertilizer are taken in proportion, are fully mixed, and are stacked for 1 h, and the obtained mixture is metered and packaged. Compared with the standard silicon fertilizer, the compound mixed silicon fertilizer of the invention has a particularly obvious improvement in fertilizer efficiency, and concretely has the advantages of great improvement of the growth vigor, the disease and pest resistance and the yield of crops, significant improvement of the lodging resistance of grain crops, reduction of the use amounts of pesticides and chemical fertilizers, and significant improvement of the quality, the hardness, the freshness lifetime and the commodity rate of some fruits. The compound mixed silicon fertilizer does not cause dust flying, and is easy to scatter.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a compound silicon fertilizer and a production method thereof. Background technique [0002] Silicon fertilizer, also known as silicon, calcium, and magnesium fertilizer, is a multi-element, compound medium-element fertilizer. At present, there are two types of silicon fertilizers: citrate-soluble silicon fertilizers and water-soluble silicon fertilizers. Citrate-soluble silicon fertilizers refer to silicon fertilizers that are insoluble in water but soluble in acid and can be absorbed by plants. China's national agricultural industry standard NY / T797--2004 stipulates that the effective silicon content of silicon fertilizer is ≥ 20%, the moisture content is ≤ 3%, and the fineness passes through a 250µm standard sieve ≥ 80%. Obviously, this standard is formulated for citrate-soluble silicon fertilizers, and citrate-soluble silicon fertilizers that meet this standard are standar...

Problems solved by technology

However, the standard silicon fertilizer is absorbed by plants too slowly, especially in alkaline soil, its fertilizer effect is not easy to fully exert, and the fertilizer effect is not significant

In addition, because the standard silicon fertilizer is a dry powder, the dust is too large when it is spread, and it is diffused everywhere. When there is wind, the dust is flying all over the sky, making field operations impossible
