Embodiment 1

[0025] The soil conditioner used for the rapid ripening of half-baked soil in this embodiment is composed of the following components in parts by weight: 6 parts of ammoniated humic acid, 10 parts of biochar, and 1 part of water-retaining agent, and the three are mixed according to their parts by weight Evenly, pass through a 60-mesh sieve.

[0026] The ammoniated humic acid is prepared according to the following method: screen the lignite in the northern region, grind the lignite into 60-mesh fine particles through a pulverizer, dry it to a moisture content of 15%, add it to the mixer, and then spray the mixer with a mass concentration of 15% % ammonia water, the weight ratio of ammonia water and lignite is 1:2, mix evenly, pack into bags and seal, and store for 4 days.

[0027] The biochar is rice husk biochar, and its preparation method is as follows: wash the rice husk with deionized water three times, dry it at 105°C to constant weight, then pulverize it, and pass through...

Embodiment 2

[0030] The soil conditioner used for the rapid slaking of half-baked soil in this embodiment is composed of the following components in parts by weight: 10 parts of ammoniated humic acid, 15 parts of biochar, and 1 part of water-retaining agent, and the three are mixed according to their parts by weight Evenly, pass through a 60-mesh sieve.

[0031] The ammoniated humic acid is prepared according to the following method: screening the lignite in the northern region, the lignite is pulverized into 70-mesh fine particles through a pulverizer, dried to a moisture content of 15%, and then added to the mixer, and then sprayed into the mixer with a mass concentration of 15% % ammonia water, the weight ratio of ammonia water and lignite is 1:3, mix evenly, pack into bags and seal, and store for 5 days.

[0032] The biochar is rice husk biochar, and its preparation method is as follows: wash the rice husk with deionized water three times, dry it at 105°C to constant weight, then pulve...

Embodiment 3

[0035] The soil conditioner used for the rapid ripening of half-baked soil in this embodiment is composed of the following components in parts by weight: 7 parts of ammoniated humic acid, 13 parts of biochar, and 3 parts of water-retaining agent, and the three parts are mixed according to their parts by weight Evenly, pass through a 60-mesh sieve.

[0036]The ammoniated humic acid is prepared according to the following method: screening the lignite in the northern region, the lignite is pulverized into 80-mesh fine particles through a pulverizer, dried to a moisture content of 10%, and then added to the mixer, and then sprayed into the mixer with a mass concentration of 15 % ammonia water, the weight ratio of ammonia water and lignite is 1:2.5, mix evenly, pack into bags and seal, and store for 6 days.

[0037] The biochar is rice husk biochar, and its preparation method is as follows: wash the rice husk with deionized water three times, dry it at 105°C to constant weight, the...

Abstract

The invention relates to a soil conditioner for quickly ripening semi-mature soil and a method for quickly ripening semi-mature soil and belongs to the technical field of soil conditioners. The soil conditioner provided by the invention is mainly composed of the following components in parts by weight: 5-10 parts of ammoniated humic acid, 10-15 parts of charcoal and 1-5 parts of water-retaining agent. The soil conditioner for quickly ripening semi-mature soil has a simple formula and is capable of improving physical and chemical properties of soil, promoting water-preserving and fertilizing level of soil, regulating soil environment, boosting plant growth and reducing volume weight of the semi-mature soil.

Description

technical field [0001] The invention relates to a soil conditioner for rapid ripening of half-baked soil and a method for quick ripening of half-baked soil, belonging to the technical field of soil conditioners. Background technique [0002] Raw soil refers to immature soil, which generally refers to the primary soil at the bottom of the soil that has not been disturbed by human life. Semi-raw soil is a soil type in which raw soil and mellow soil are mixed. Due to its immature development, low nutrient availability, and poor physical and chemical properties, it is not suitable for the growth and development of crops. It needs to be matured through the accumulation of biological cycles or artificial fertilization. [0003] Coal gangue and other wastes in coal mining areas occupy a large amount of land, and the surface of the waste needs to be covered with 50 cm of soil to be reclaimed. Due to the limited remains of the surface "ripe soil" during mining, the surface area of ...
