Problems solved by technology

The latter uses water as the matrix, but due to the influence of the solubility of each component, the nutrient content is low, and the integration of multiple components is prone to crystallization or precipitation, and the packaging barrel is prone to flatulence during high temperature and transportation. phenomenon, so it has certain restrictions in production, storage and use
Recently, there are many kinds of liquid calcium fertilizers on the market, but the nutrient content is often low, such as Ruisi calcium, etc., the calcium content cannot reach 160g / L, and the products are often not in a fluid state, which is not conducive to water solubility and foliar spraying

Embodiment 1

[0021] Embodiment 1 prepares calcium-containing liquid fertilizer

[0022] The formula is shown in Table 1.

[0023] Table 1: Raw material ratio of high-concentration quick-acting fluid calcium fertilizer

[0024]

[0025] The gel thickener used in this example is xanthan gum (this formula uses Fufeng brand xanthan gum from Shanghai Liqi Chemical Auxiliary Co., Ltd.).

[0026] The macromolecular polysaccharide substance used in this example is sodium carboxymethyl cellulose (this formula uses Lite brand carboxymethyl cellulose sodium from Weifang Lite Composite Materials Co., Ltd.).

[0027] The preparation method steps are as follows:

[0028] (1) Take 30‰ of water, heat it to 80°C±2°C, add gel thickener, and emulsify continuously until the solution is viscous (viscosity μ=1.6Pa·s), cool to 50°C, and stand After 12 hours, a transparent colloid was obtained and set aside;

[0029] (2) Take the remaining 200‰ of water and heat it to 50°C±2°C; dissolve the macromolecular ...

Abstract

The invention discloses calcium-containing liquid manure. The calcium-containing liquid manure comprises the following components in percentage by weight: 0.50-1.00 per mill of gel thickening agent material, 0.20-0.30 per mill of macromolecule polysaccharide material, 650-70 per mill of Ca(NO3)2.4(H2O), 50-70 per mill of ethylenediamine tetraacetic acid zinc, 10.0-13.0 per mill of ethylenediamine tetraacetic acid zinc copper, 10.0-13.0 per mill of ethylenediamine di-o-phenyl ferric acetate and the balance of water. The calcium-containing liquid manure disclosed by the invention forms a stable solvent by adopting a colloid chemical technology, the solubility of calcium ions can be increased, the calcium-containing liquid manure has good solubility and high calcium nutrient content, is rich in trace elements and reasonable in proportioning and has the characteristics of non-precipitation, non-crystallization, non-water releasing, non-generation of gas and the like, and therefore, the calcium-containing liquid manure is a high-concentration quick-acting fluid calcium fertilizer and can be used through leaf surface spraying and drip fertigation.

Description

technical field [0001] The invention relates to a medium-element water-soluble fertilizer for foliar spraying and drip fertigation, in particular to a high-concentration calcium-containing liquid fertilizer produced by colloidal chemical technology and a preparation method thereof. Background technique [0002] In recent years, the role of secondary elements in agricultural production has been paid more and more attention. Calcium is an important and essential nutrient element for crops, and its research and application have increased in recent years. [0003] Calcium is an essential nutrient element for plants, and plays a central role in the regulation of plant growth and development and response to environmental stress. Studies have shown that calcium plays an inestimable role in plants. Calcium can stabilize cell membrane and cell wall, and also participate in second messenger transmission, regulate osmosis, and have enzymatic effect, etc. Calcium deficiency in plants ...
