Embodiment 1

[0019] In the embodiment of the present invention, a solid soil conditioner containing titanium citrate and potassium citrate consists of the following raw materials in parts by weight: 9 parts of titanium citrate, 22 parts of potassium citrate, 25 parts of black rice husk, 11 parts of heartwood, 5 parts of N-methylpyrrolidone.

[0020] Mix N-methylpyrrolidone with 12 times the mass of deionized water to prepare N-methylpyrrolidone solution. The black rice husk and split wood were mixed and crushed, passed through a 120-mesh sieve, and an aqueous solution of acetic acid 4 times the mass of the two was added, and stirred at 88°C for 2.5 hours to obtain a mixture. Mix potassium citrate and N-methylpyrrolidone solution, raise the temperature to 80°C, and stir at this temperature for 55 minutes, then add titanium citrate, raise the temperature to 160°C, heat up to 160°C, and heat it under a hydrogen atmosphere for 2 hours, then lower the temperature to 72 ℃, add the mixture, and ...

Embodiment 2

[0022] In the embodiment of the present invention, a solid soil conditioner containing titanium citrate and potassium citrate is composed of the following raw materials in parts by weight: 17 parts of titanium citrate, 30 parts of potassium citrate, 35 parts of black rice husk, 19 parts of heartwood, 12 parts of N-methylpyrrolidone.

[0023] Mix N-methylpyrrolidone with 12 times the mass of deionized water to prepare N-methylpyrrolidone solution. Black rice husks and split wood were mixed and crushed, passed through a 120-mesh sieve, an aqueous acetic acid solution 4 times the mass of the two was added, and stirred at 88°C for 2.8 hours to obtain a mixture. Mix potassium citrate and N-methylpyrrolidone solution, heat up to 80°C, and stir at this temperature for 60 minutes, then add titanium citrate, heat up to 160°C, heat up to 160°C, heat up to 2h in a hydrogen atmosphere, and then cool down to 72 ℃, add the mixture, and ultrasonically treat at this temperature for 40min, th...

Embodiment 3

[0025] In the embodiment of the present invention, a solid soil conditioner containing titanium citrate and potassium citrate consists of the following raw materials in parts by weight: 11 parts of titanium citrate, 24 parts of potassium citrate, 28 parts of black rice husk, 13 parts of heartwood, 7 parts of N-methylpyrrolidone.

[0026] Mix N-methylpyrrolidone with 12 times the mass of deionized water to prepare N-methylpyrrolidone solution. The black rice husk and split wood were mixed and crushed, passed through a 120-mesh sieve, and an aqueous solution of acetic acid 4 times the mass of the two was added, and stirred at 88°C for 2.6 hours to obtain a mixture. Mix potassium citrate and N-methylpyrrolidone solution, raise the temperature to 80°C, and stir at this temperature for 58 minutes, then add titanium citrate, raise the temperature to 160°C, heat up to 160°C, and heat up to 80°C for 2 hours, then cool down to 72 ℃, add the mixture, and ultrasonically treat at this te...

Abstract

The invention discloses a solid soil improvement agent containing titanium citrate and potassium citrate and application thereof. The solid soil improvement agent is prepared from the following raw materials in parts by weight: 9-17 parts of titanium citrate, 22-30 parts of potassium citrate, 25-35 parts of black rice husk, 11-19 parts of diaphragma juglandis and 5-12 parts of N-methyl pyrrolidone. The prepared solid soil improvement agent reduces the pH value and salinity of soil under the synergistic effect of the raw materials; the soil alkalization degree is greatly reduced; and the soil hardening hardness is obviously reduced, the permeability is obviously improved, and soil with a very loose granular structure is formed, so that the soil has excellent fertilizer retention, water retention and air permeability properties, and the growth of a plant root system is greatly benefited. The solid soil improvement agent disclosed by the invention can greatly improve the emergence rate of planted crops and greatly improve the crop yield, the adopted raw materials are simple and available, a preparation technology is simple and easy to operate, easy control and stable properties are realized, and the solid soil improvement agent is applicable to industrial production.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a solid soil improver containing titanium citrate and potassium citrate and an application thereof. Background technique [0002] Saline-alkali soil is a type of soil formed by salinization or alkalization, including saline soil, alkaline soil and various saline-alkali soils. In arid and semi-arid areas, the salt contained in the bottom soil and groundwater, due to ground evaporation, will cause the salt water to rise to the surface layer with the capillary action of the soil. After the water evaporates, the salt will remain on the soil surface and accumulate. And form saline-alkali land. Due to permanent seawater intrusion in coastal areas, saline-alkali land is widely distributed, with high salt content, and excessive soluble salts accumulate on the soil surface or in the soil. The surface soil of saline-alkali land is mostly dry and white, and even forms salt crust,...
