Embodiment 1

[0017] A biological cultivation substrate with chitin as raw material is prepared from the following steps:

[0018] 1) Degreasing, desalination, dehydration

[0019] The fat of the crab shells and shrimp shells was removed by artificial rolling, then the crab shells and shrimp shells were desalinated in hot water above 85°C for 25 minutes, and then the carapaces were dried to a water content of 5%;

[0020] 2) get the crab shell 4kg, the shrimp shell 6kg after step 1) processing, join in the reactor after mixing, add the 5% glacial acetic acid solution of the water of 5g Bacillus pumilus (Bacillus pumilus), 95kg and 5kg again, The constant temperature was 45°C for 3 hours. Among them, Bacillus pumilus was purchased from Shanghai Xinran Biotechnology Co., Ltd., and the bacterial content was 6.8×10 9 Pieces / g (bacteria liquid);

[0021] 3) Get 10kg of mixed crab shells and shrimp shells processed in step 2), add 100kg of 2% hydrochloric acid solution, and maintain a constant ...

Embodiment 2

[0026] In this example, the biological cultivation substrate prepared in Example 1 is used to grow crops, and the crop is selected as an example of cucumber. The specific cultivation methods are as follows:

[0027] 1) before planting cucumber seedlings, according to the amount of the dry chicken manure of 25kg per mu of land +1500kg, the above-mentioned two kinds of fertilizers are mixed evenly (the amount of dry chicken manure used in normal planting cucumber is 3000kg / mu), spread evenly, Deep ploughing 30cm of land, making a 45cm border, and arranging the land to be planted;

[0028] 2) Immediately water after transplanting strong seedlings to slow the seedlings.

[0029] 3) 15--20 days enter the flowering period, for the plants with weak growth conditions, each plant can be topdressed with the biological cultivation substrate prepared by the present invention of 2-3g, to promote growth;

[0030] 4) Enter the fruiting stage after 30 days, observe the growth of the fruit, ...

Abstract

The invention relates to a biological culture medium using chitin as a raw material. The biological culture medium is prepared from crab shells and shrimp shells through degreasing, desalting, dewatering, fermentation and acidolysis in a fungal acid solution, crushing and drying. According to the biological culture medium using the chitin as the raw material, the preparation method is simple, the raw materials are sufficient, a large quantity of waste chitin can be consumed, the high-quality chitin culture medium can also be provided, and the culture medium can be used for effectively improving the soil environment and digest remaining pesticide and heavy metals in soil.

Description

technical field [0001] The invention relates to agricultural fertilizers, in particular to a biological cultivation substrate using chitin as raw material. Background technique [0002] In modern agricultural soil, due to the long-term use of chemical fertilizers and pesticides, the types and types of vitamins, sugars, calcium, minerals and trace elements in the soil are reduced and unbalanced; the types and quantities of beneficial bacteria in the soil are reduced, and the pH value is unbalanced , the soil is compacted, the beneficial organisms are reduced, and the pesticide and heavy metal residues in the soil are serious. [0003] In coastal cities, especially in the breeding areas of crustaceans, the shells are thrown away as waste, and the discarded waste is not easy to degrade, which not only wastes a lot of chitin, but also causes great environmental pollution. SUMMARY OF THE INVENTION [0004] The technical problem solved by the present invention is to provide a b...
