Embodiment 1

[0023] Example 1 A plant culture substrate

[0024] The plant culture substrate consists of the following components and their weight percentages:

[0025] Sewage treatment plant sludge 30%, coconut soil 35%, vermiculite 30%, wheat straw 0.4%, rice husk 0.2%, snake sawdust 0.3%, chitosan 0.09%, polyvinyl alcohol 0.01%, coconut water 1%, Zeatin 1% and sodium silicate aqueous solution 2%.

[0026] Preparation:

[0027] S1. Mix the coconut soil and vermiculite evenly, crush and sieve to form particles with a particle size of less than 5mm to obtain mixture A;

[0028] S2. Mix the sewage treatment plant sludge with the mixture A obtained in step S1 uniformly, dry at 180°C to form a solid with a total pore gap of 70%, and crush to a particle size of less than 3mm to obtain a mixture B;

[0029] S3. After mixing wheat stalks, rice husks and snake sawdust evenly, treat them with steam explosion technology, then add chitosan and polyvinyl alcohol and mix them evenly to obtain plant fiber water ...

Embodiment 2

[0031] Example 2 A plant culture substrate

[0032] The plant culture substrate consists of the following components and their weight percentages:

[0033] Sewage treatment plant sludge 40%, coconut soil 30%, vermiculite 20%, wheat straw 0.8%, rice husk 0.4%, snake sawdust 0.6%, chitosan 0.18%, polyvinyl alcohol 0.02%, coconut juice 3%, Zeatin 2% and sodium silicate aqueous solution 3%.

[0034] The preparation method is similar to Example 1.

Embodiment 3

[0035] Example 3 A plant culture substrate

[0036] The plant culture substrate consists of the following components and their weight percentages:

[0037] Sewage treatment plant sludge 50%, coconut soil 25%, vermiculite 10%, wheat straw 1.2%, rice husk 0.6%, snake sawdust 0.9%, chitosan 0.27%, polyvinyl alcohol 0.01%, coconut juice 5%, Zeatin 3% and sodium silicate aqueous solution 4%.

[0038] The preparation method is similar to Example 1.

Abstract

The invention belongs to the field of plant culture mediums, and specifically relates to a plant culture medium and a preparation method thereof. The plant culture medium provided by the invention comprises the following components in percentages by weight: 30 to 50% of sludge, 25 to 35% of coco peat, 10 to 30% of vermiculite, 1 to 3% of a plant fiber water absorbent, 1 to 5% of coconut juice, 1 to 3% of zeatin and 2 to 4% of a sodium silicate aqueous solution. The plant culture medium provided by the invention contains high nutrition, and has good water-holding, fertilizer-preserving and air-permeable performances. Meanwhile, the follow-up work of sewage treatment is solved; and highly-efficient resource utilization of wastes is realized.

Description

Technical field [0001] The invention belongs to the field of plant culture substrates, and specifically relates to a plant culture substrate and a preparation method thereof. Background technique [0002] The treatment and disposal of sludge is a continuation of sewage treatment. Currently, the commonly used sludge disposal methods are mainly: landfill, incineration, agriculture and landscaping. Due to the high degree of nutrient activation of sludge, nutrient loss is prone to occur under water and wet conditions. Surface and underground runoff will cause serious secondary environmental pollution, which not only poses a threat to my country’s environmental quality and public health, but also violates my country’s sludge. Targets for reduction, stabilization and harmlessness of treatment. With the improvement of people's quality of life and the improvement of living and living environment, there is a huge demand for plant culture media with good water retention, fertilizer retenti...
