specific Embodiment approach 1

[0037] Specific implementation mode one: this implementation mode is a kind of preparation method that is rich in humus artificial simulated soil, is to finish according to the following steps:

[0038] 1. Prepare the soil mixture:

[0039] Mix biomass material powder or glucose with the problem soil, then add alkaline additives and distilled water, and stir evenly to obtain a soil mixture;

[0040] The mass ratio of biomass material powder, problem soil, alkaline additive and distilled water described in step 1 is (3~5):(0.5~50):(0.3~2):(25~100);

[0041] The mass ratio of glucose, problem soil, alkaline additive and distilled water described in step 1 is (3~5):(0.5~50):1.0:(25~50);

[0042] The biomass material powder described in step 1 is prepared according to the following steps:

[0043] First, the biomass material is cleaned to remove impurities on the surface of the biomass material, then dried, and finally the dried biomass material is crushed to obtain biomass mate...

specific Embodiment approach 2

[0052] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, the biomass material is first cleaned to remove impurities on the surface of the biomass material, and then dried at a temperature of 60°C to 80°C for 10h to 24h . Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0053] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the biomass material described in step 1 is one of corn stalks, rice husks, leaves and sawdust or a mixture of several of them . Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a preparation method of artificial simulated soil rich in humus, which relates to a preparation method of simulated soil. The purpose of the invention is to solve the problem that the existing organic fertilizer has low tolerance to rainwater erosion, which further affects its repairing effect on problem soil. Methods: 1. Prepare the soil mixture; 2. Put the soil mixture in a high-temperature and high-pressure hydrothermal reaction kettle for hydrothermal reaction to obtain artificial simulated soil rich in humus. The preparation method of the present invention is simple, and the raw materials are cheap and easy to obtain, so it is suitable for large-scale synthetic preparation; the artificial simulated soil rich in humus prepared by the present invention is used to increase soil water holding capacity and absorbability to nutrient elements.

Description

technical field [0001] The invention relates to a preparation method of simulated soil. Background technique [0002] Black soil, also known as black soil chernozem, is one of the most fertile soil resources for crop production in the world. Black soil has high organic matter content, fertile soil, and thick humus stored, which is most suitable for farming. In order to feed a growing world population, black soils have undergone severe degradation over the past few decades. In particular, due to the abuse of pesticides, chemical fertilizers, etc. and the backward restoration system, soil erosion and pollution are serious, and barren soil, saline-alkali soil, and polluted soil have gradually formed. [0003] Although the existing organic fertilizers for different soil problems can solve the problems of soil salinization, serious compaction, poor soil, and soil fertility decline from the aspects of physics, biology, and chemistry to a certain extent, but due to their signific...
