Embodiment 1

[0028] Preparation of Soil Improver Containing Red Algae Extract

[0029] Get 100g of red algae, wash and chop, and prepare according to the following steps:

[0030] (1) Microwave extraction treatment:

[0031] Wash and chop the seaweed, perform microwave extraction with 40 times the weight of water, irradiate for 5-10 minutes, microwave power 800-1200W, temperature 35°C, extract 3 times in total, and combine the extracts from 3 times;

[0032] (2) Enzymolysis:

[0033] Concentrate the microwave-treated extract in step (1) under reduced pressure to 1 / 3 of the original volume, and add a compound enzyme preparation composed of cellulase, β-glucanase, and papain at a ratio of parts by weight of 1.2:2.1:1.6 , take it out after 8 hours in a constant temperature water bath at 30°C, put it in -18°C for quick freezing into ice, take it out and let it melt at room temperature, and repeat the quick freezing and thawing cycle three times;

[0034] (3) Bacteria fermentation:

Embodiment 2

[0038] Embodiment 2: Preparation of soil conditioner containing macroalgae extract

[0039] (1) Microwave extraction treatment:

[0040] Get 100g macroalgae, wash and chop, and prepare according to the following steps:

[0041] Wash and chop the macroalgae, extract by microwave with 10 times the weight of 95% ethanol, irradiate for 5-10min, microwave power 800-1200W, temperature 50°C, extract 3 times in total, and combine the extracts from 3 times;

[0042] (2) Enzymolysis:

[0043] Concentrate the microwave-treated extract in step (1) under reduced pressure to 1 / 4 of the original volume, and add a compound enzyme preparation composed of cellulase, β-glucanase, and papain at a ratio of parts by weight of 3.6:5.2:4.5 , take it out after 8 hours in a constant temperature water bath at 30°C, put it in -18°C for quick freezing into ice, take it out and let it melt at room temperature, and repeat the quick freezing and thawing cycle three times;

[0044] (4) Bacteria fermentatio...

Embodiment 3

[0049] Embodiment 3: Taking the pollution of dichloroethyl ether in the control soil as an example

[0050] Preparation of soil improver: take the soil improver in Examples 1 and 2 respectively, add 0.1-0.2% by weight into the polluted soil, and fully stir.

[0051] According to domestic standards: the soil standard (migration to groundwater) in the "Industrial Enterprise Soil Environmental Quality Risk Assessment Standard (HJ / T25-1999)" is 4.7mg / kg. The content of dichloroethyl ether in the examples is all lower than the national standard.

[0052] Conclusion: It can be seen from the test results that the seaweed extract soil conditioner can quickly and efficiently reduce the content of dichloroethyl ether in the soil when it is used, and it can be used for the treatment and restoration of dichloroethyl ether soil pollution.

Abstract

The invention provides a preparation method for a soil improver. According to the preparation method, an algae plant is used as a raw material; extraction efficiency of the algae active substances is obviously increased through acid-base extraction, enzymolysis and microwave treatment; and microflora fermentation and gold probiotic fermentation are used to modify the active ingredients, so that the soil improver has the functions of decomposing large molecular clusters and removing harmful substances. The soil improver can be applied in improving health of organisms and improving water, air and soil environment.

Description

technical field [0001] The invention relates to a preparation method of a soil conditioner, in particular to a biological extraction method of functional active substances of seaweed plants, a preparation method of a soil conditioner using seaweed plants as raw materials and its application. Background technique [0002] At present, people pay more and more attention to urban environmental protection and environmental pollution is gradually being controlled, while rural environmental problems are becoming more and more prominent. Various pollutions and ecology are intertwined, affecting the lives of rural population and threatening them. health, while bringing serious pollution to rural farmland. Farmland pollution caused by agricultural activities refers to the addition of certain harmful substances or high levels of certain inherent substances in the soil during the process of fertilization and irrigation by the agricultural sector, and the pollution load exceeds the beari...
