Method for improving acid soil using ground mass

Abstract

The invention discloses a method for improving the acid soil condition by using a matrix and belongs to the technology field of the soil improvement. The method is composed of seven steps including matrix preparation, pH value measurement, matrix amount confirmation, matrix applying time, soil humidity control, matrix applying operation and pre-plant soil preparation. The matrix is made from imperatoria and prepared by adopting the technological processes of drying, chopping, fermenting by using the Dadiwang viable bacteria stock solution, etc., wherein the imperatoria is suitable for being planted in the tropical area, and has rapid growth, high yield and sustainability, and the required matrix total amount of the soil improvement can be figured out by confirming the required matrix amount of neutralizing 1m<2> of the acid soil. The matrix is quantificationally mixed with the acid soil for more than two times. The method can effectively change the pH value and the physical behavior of the soil and can increase the soil fertility; the pH value of the soil can be directly increased from 4-6 to 6-8, so that the acidity and basicity of the soil is suitable for the plant growth; the soil bulk density is reduced by 10%, the soil porosity is increased by more than 15%, and the water holding capacity of the soil is increased by more than 20%.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for improving acidic soil and its physical properties and increasing soil fertility. Background technique [0002] With the emission of automobile exhaust and industrial sulfur dioxide, air pollution is caused, and the acid rain formed causes soil compaction, which is highly acidic, difficult for plant growth, and even causes plant death. The impact of soil pH on nutrient availability is mainly manifested in the following points: [0003] 1. Within the normal range, the reason why plants are sensitive to soil acidity and alkalinity is that the pH value of the soil affects the concentration of various ions in the soil solution, which affects the availability of various elements to plants; [0004] 2. The influence of soil acidity and alkalinity on the availability of nutrients: [0005] (1) Nitrogen is more effective at pH 6-8, because when the pH value is less...

Problems solved by technology

[0012] The present invention overcomes lime, calcium-containing shell ash, purple shale powder, fly ash, plant ash, etc. to neutralize active acid, latent acid, and improve soil structure in the prior art, but there are problems such as labor-saving processing, high cost, and resource Non-renewable, while changing the acidity of the soil, it will also increase the adverse consequences such as soil compaction, and other physical properties of the soil cannot be improved.
