Embodiment 1

[0034] The present embodiment provides a kind of fertilizer that prevents land salinization, and preparation method is as follows:

[0035] In parts by weight, 10 parts of nano-nitrohumic acid (particle size is 70nm), 5 parts of beta-polymalic acid fermented product, 0.1 part of trace element amino acid chelate and 0.1 part of microbial bacterial agent are mixed to obtain soil salt prevention Alkalizing fertilizer 1.

[0036] Among them, the β-polymalic acid fermentation product is obtained by fermentation of Aureobasidium pullulans, and the fermentation medium includes glucose, ammonium succinate and calcium carbonate, and the concentrations of glucose, ammonium succinate and calcium carbonate in the medium are sequentially 110g / L, 3.6g / L and 45g / L.

[0037] The trace element amino acid chelate is composed of amino acid chelated iron, amino acid chelated zinc, amino acid chelated copper, amino acid chelated manganese, amino acid chelated selenium and amino acid chelated boro...

Embodiment 2

[0040]The present embodiment provides a kind of fertilizer that prevents land salinization, and preparation method is as follows:

[0041] In parts by weight, 20 parts of nano-nitro humic acid (particle size is 150nm), 10 parts of beta-polymalic acid fermented product, 0.5 part of trace element amino acid chelate and 0.5 part of microbial bacterial agent are mixed to obtain soil salt prevention Alkalizing fertilizer 2.

[0042] β-polymalic acid fermentation product, trace element amino acid chelate and microbial inoculant are the same as in Example 1.

Embodiment 3

[0044] The present embodiment provides a kind of fertilizer that prevents land salinization, and preparation method is as follows:

Abstract

The invention relates to the technical field of fertilizers, in particular to a fertilizer for preventing land salinization and a preparation method thereof. The invention provides the fertilizer for preventing land salinization, the fertilizer comprises the following components: nitro humic acid, beta-polymalic acid leavening, trace element amino acid chelate and microbial agent, does not leave weak acid radicals to form salt and alkali after being applied to soil, and can prevent land salinization and improve soil quality, and the fertilizer has an obvious improvement effect on saline-alkali soil, the salt content and the pH value of the saline-alkali soil can be reduced, and the nitro humic acid, the beta-polymalic acid leavening and the microbial agent have a synergistic effect in the aspect of improving the saline-alkali soil. The invention provides the preparation method of the fertilizer for preventing land salinization. The fertilizer for preventing land salinization prepared by the preparation method can achieve the effect of long-acting improvement of saline-alkali soil. Moreover, the preparation method is simple in process, mild in condition and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer for preventing land salinization and a preparation method thereof. Background technique [0002] Due to people's pursuit of high economic benefits, driven by planting experience and market, as well as excessive application of chemical fertilizers, the phenomenon of monoculture is common, and the problem of soil degradation is becoming increasingly prominent. For example, the nitrogen fertilizer applied is mainly urea, accounting for more than 60% of the total nitrogen fertilizer consumption. The aqueous solution of urea is alkaline, and after being applied to the soil, it is first converted into ammonium bicarbonate (NH 4 HCO 3 ), ammonium ions are absorbed by crops, leaving bicarbonate (HCO 3 - ) in the soil, resulting in an increase in soil pH and soil salinization. Soil salinization not only destroys the ecological environment, but also seriously affects ...
