Problems solved by technology

However, there is a lack of research and development and application of existing technologies. Therefore, it is extremely important to allocate resources on a global scale, accelerate the utilization of woody peat resources, improve the quality of existing cultivated land, and promote the development of agricultural modernization.

Embodiment 1

[0057] A formula for rapidly improving farmland soil fertility based on high-quality natural humus materials. The ratio of raw materials by mass is as follows: 2 parts of woody peat humus, 0.3-0.9 parts of active organic materials formed by fermentation of biomass materials, and 0.1 parts of microbial stimulation regulators , where the addition amount of woody peat humus is the amount of refractory organic matter in the soil to be improved, the amount of active organic matter material formed by fermentation of biomass materials is the amount of easily decomposable organic matter in the soil to be improved, and the addition of microbial stimulation regulator The amount is 100kg / mu, which is convenient for mechanized operation.

[0058] Based on the above method of using a formula based on high-quality natural humus materials to quickly improve the soil fertility of farmland, the steps are as follows:

[0059] Step 1. Collect the fertile plow soil of the target type of soil for ...

Embodiment 2

[0065] Same as Example 1, the difference is that the refractory organic matter is humus, humin is humin, fulvic acid and humic acid, the biomass material is at least one of straw or herbaceous plant residue, and the active organic matter material is rich in active Biomass organic materials with soil organic matter components, wherein the active soil organic matter components are polysaccharides, organic acids, and amino sugars. The preparation method of the woody peat humus is as follows: use a high-speed shearing machine for physical activation or use a high-efficiency reactor for chemical activation. In this way, the woody peat is partially activated or fully activated, and the dissolved organic matter is removed by means of separation and purification to obtain the woody peat humus; the physical activation is physically crushed by a high-speed shearing machine, and the woody peat raw material is crushed to a particle size The diameter is no more than 1 mm to obtain woody pea...

Abstract

Provided is a formula for rapidly improving the farmland soil fertility based on a high-quality natural humus material and a use method. Natural woody peat is used as a basic raw material to carry out a chain scission process to produce a humus material which replaces difficult-to-decompose organic matters in soil, an active organic matter material produced by fermenting a biomass material is used to replace easy-to-decompose organic matters in soil, and an inducing microorganism excitation regulator is added, so that indigenous microorganisms in soil are quickly converted towards fertile soil, the conversion of nutrient elements such as soil C, N, P and K is promoted, and rapid circulation of the system is activated. A combination formula capable of rapidly improving farmland soil fertility is formed. Based on the principle of similar synergism of soil organic matters and the mechanism of synergistic effect improvement of soil organic matters-microorganisms-aggregates, the soil fertility can be rapidly improved through mechanical engineering operation. Conventional straw returning is carried out in the cultivation period, and the soil organic matter decomposition attenuation part is compensated through root systems, secretions of the root systems and straw returning, so that the soil fertility can be continuously kept.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and specifically relates to a formula and a use method for rapidly improving farmland soil fertility based on high-quality natural humus materials. Background technique [0002] Natural woody peat resources are similar in composition and properties to soil organic matter. Composition analysis shows that the content of stable organic matter exceeds 90%, and the content of humic acid exceeds 40%. As attached to the manual figure 2 As shown, the scanning electron microscope analysis pointed out that the microstructure is similar to that of soil organic matter, and is essentially different from the microstructure of biochar and lignite. Natural woody peat resources have the same root as soil humus. They are organic minerals formed by the accumulation and transformation of dead tree residues in forest swamps. The content of heavy metals is lower than the background value of the soil. , safe...
