Embodiment 1

[0025] Following three kinds of formulas are the preferred formulas of mineral matter of the present invention, specifically:

[0026] Product 1 is composed of the following components in parts by weight: 52 parts of minerals, 4 parts of hydrophobic carbohydrate fatty acids, 8 parts of sodium hydroxymethylcellulose, 10 parts of cellulose-based activated carbon, and 70 parts of water; the minerals are natural gypsum ore A mixture of attapulgite and attapulgite; the mass ratio of natural gypsum ore to attapulgite is 3:1.

[0027] Product 2 consists of the following components in parts by weight: 55 parts of minerals, 6 parts of epoxy resin, 10 parts of acrylic acid, 15 parts of cellulose-based activated carbon, and 75 parts of water; the minerals are a mixture of natural gypsum ore and attapulgite, natural gypsum The mass ratio of ore to attapulgite is 3:1.

[0028] Product three consists of the following parts by weight: 58 parts of minerals, 8 parts of epoxy resin, 13 parts o...

Embodiment 2

[0038] The three products in Example 1 were applied to the planting of rice in saline-alkali soil. The experimental group was the planting field using the mineral material product 1, product 2 and product 3 of the present invention, and the control group was the planting field that did not apply the mineral material of the present invention. Ueda; The performance parameters of the saline-alkali land were tested before and after the experiment, and the rice yields in the experimental group and the control group were recorded after the experiment.

[0039] General situation of the test field: The soil salinization in the test field is serious, and the pH value is above 8.0, and even above 8.5 in serious cases. The total salt content of the 0-40cm topsoil is 2.06%, and the conductivity is 7.76, which is a typical saline soil. The test crop was rice.

[0040] Field test results: the crop emergence rate and output after the improvement of the mineral material of the present inventi...

Abstract

The invention discloses a natural mineral soil conditioning nutritional agent as well as a preparation method and application thereof, and belongs to the technical field of soil improvement materials.The mineral material is composed of the following components in parts by weight: 50-60 parts of minerals; 2-10 parts of a binder; 5-15 parts of a humectant; 10-20 parts of an acidic compound fertilizer; and 70-80 parts of water. The minerals are a mixture of natural gypsum ore and attapulgite. According to the invention, the natural gypsum ore and attapulgite are used as main raw materials of thenatural mineral soil conditioning nutritional agent, so that water-soluble anions and cations of the product are in a range suitable for crop growth; and the material is simple in preparation method,low in cost and good in practicability.

Description

technical field [0001] The invention belongs to the technical field of soil improvement materials, and in particular relates to a natural mineral soil conditioning nutrient and its preparation method and application. Background technique [0002] my country's soil is one of the countries most seriously harmed by desertification and salinization in the world. Desertification and salinization have a large area and wide distribution, exacerbating the deterioration of the ecological environment, and large areas of beaches and tidal flats are constantly eroding the surrounding soil , has seriously affected the development of my country's industry, agriculture and social economy, threatened the survival and development space of the nation, and caused serious economic losses. [0003] At present, the following methods are commonly used to control the combined pollution of heavy metals and organic matter: combined physical and chemical remediation, chemical and biological remediation...
