Embodiment 1

[0058] Embodiment 1, preparation suspension type fungicide liquid medicinal fertilizer

[0059] 1. Formula

[0060] In parts by weight, the formula of the suspension type fungicide liquid medicinal fertilizer of the present embodiment is as follows:

[0061] Nitrogen fertilizer with 10 parts of nitrogen, phosphate fertilizer with 35 parts of phosphorus, potash fertilizer with 10 parts of potassium, 2 parts of trace element fertilizer, 2.5 parts of fungicide, 1 part of emulsifier, 4 parts of dispersant, 3 parts of filler, 0.5 Part defoamer, 5 parts antifreeze, 0.4 part thickener and 40 parts water;

[0062] Concretely consists of the following raw materials:

[0063]

[0064] 2. Preparation method

[0065] Prepare suspension type fungicide liquid medicinal fertilizer according to the following steps:

[0066] (1) Under the stirring condition that the rotating speed is 1000 rev / min, add nitrogenous fertilizer urea-ammonium nitrate solution that nitrogen content is 100g, p...

Embodiment 2

[0073] Embodiment 2, preparation suspension type fungicide liquid medicinal fertilizer

[0074] According to the steps in Example 1, the suspension-type fungicide liquid medicinal fertilizer is prepared, and the remaining steps are unchanged in Example 1. Only adding sulfuric acid with a mass fraction of 100g in step (5) can prepare a pH value of 3.05. Liquid medicinal fertilizer, the percentage of solid particles in the medicinal fertilizer is 25%, which can be kept for half a year without stratification or precipitation.

Embodiment 3

[0075] Embodiment 3, preparation suspension type fungicide liquid medicinal fertilizer

[0076] According to the steps in Example 1, the suspension-type bactericide liquid medicinal fertilizer is prepared, and the remaining steps are unchanged in Example 1. Only adding sulfuric acid with a mass fraction of 75g in step (5) can prepare a pH value of 3.55. Liquid medicinal fertilizer, the percentage of solid particles in the medicinal fertilizer is 25%, which can be kept for half a year without stratification or precipitation.

Abstract

The invention discloses suspension-type bactericide liquid medicine fertilizer and a preparation method thereof. The suspension-type bactericide liquid medicine fertilizer comprises nitrogen fertilizer, phosphorous fertilizer, potassium fertilizer, trace element fertilizer, bactericide, emulsifier, dispersant, filler, defoamer, antifreezing agent, thickener and water and further comprises pH regulator. Medicine and fertilizer are combined in a form of a suspending agent; through joint action of reasonable formulation, proper auxiliary and good processes of an ultramicro grinding machine and a high-speed dispersing machine, stability, uniformity and fluidity of the medicine fertilizer are high, degradation rate is low, and the medicine fertilizer can be maintained being free of layering and precipitating for half a year; the process is simple and reasonable, material grinding size is shortened as much as possible, energy consumption is low, and the medicine fertilizer is suitable for industrialized production.

Description

technical field [0001] The invention relates to a suspension-type bactericide liquid medicinal fertilizer and a preparation method thereof, belonging to the technical field of agricultural medicinal fertilizers. Background technique [0002] Agricultural production is inseparable from medicine and fertilizer, but in most cases, medicine and fertilizer are applied alone, which wastes a lot of labor and time costs. Medicinal fertilizer is not a new concept. As early as the 1980s, Japan's medicinal fertilizer research technology had already matured. In the mid-1960s, American researchers discovered that Niancaojing can strongly inhibit nitrification and denitrification, reduce nitrogen loss, and enhance biological nitrogen fixation. It can be seen that the combination of medicine and fertilizer can promote each other. Patent No. 95113702.6 Plant Growth Medicinal Fertilizer, puts forward the concept of Medicinal Fertilizer, using fertilizer metal ions to achieve insecticidal, ...
