Embodiment 1

[0055]Collect the camellia oleifera shell, wash it, dry it in an oven at 65°C for 12 hours, crush it, and pass it through a 2mm sieve to obtain the camellia oleifera shell powder; add water to the camellia oleifera shell powder, and the dosage is 9mL of water per 1g of the camellia oleifera shell powder. Then place it in a constant temperature water bath at 35°C for extraction for 1 hour, then place it on a vibrator (HY-2 type) for 30 minutes and vibrate at a frequency of 85 Hz; finally filter, and the filtrate is the camellia oleifera husk extract.

Embodiment 2

[0057] Collect the camellia oleifera shell, wash it, dry it in an oven at 65°C for 12 hours, crush it, and pass it through a 2mm sieve to obtain the camellia oleifera shell powder; add water to the camellia oleifera shell powder, and the dosage is 9mL of water per 1g of the camellia oleifera shell powder. Then place it in a constant temperature water bath at 35°C for extraction for 1 hour, then place it on a vibrating machine for 60 minutes and vibrate at a frequency of 85 Hz; finally filter, and the filtrate is the camellia oleifera husk extract.

Embodiment 3

[0059] Collect the camellia oleifera shell, wash it, dry it in an oven at 65°C for 12 hours, crush it, and pass it through a 2mm sieve to obtain the camellia oleifera shell powder; add water to the camellia oleifera shell powder, and the dosage is 9mL of water per 1g of the camellia oleifera shell powder. Then place it in a constant temperature water bath at 35°C for extraction for 2 hours, then place it on a vibrating machine for 30 minutes and vibrate at a frequency of 85 Hz; finally filter, and the filtrate is the camellia oleifera husk extract.

Abstract

The invention belongs to the technical field of oil tea shell reuse, and particularly relates to oil tea shell extract liquid and a preparation method and application thereof. The preparation method of the oil tea shell extract liquid comprises the following steps of collecting oil tea shells, and conducting washing, drying, crushing and sieving to obtain oil tea shell powder; adding water to theoil tea shell powder, conducting immersing extraction at a constant temperature, and then conducting shaking and filtering to obtain a filtrate which is the oil tea shell extract liquid. The extract liquid is applied to soil, gas is collected periodically, the content of nitrous oxide in the gas emitted from the soil is detected, and it is found that the extract liquid can greatly reduce the emission rate of nitrous oxide in the soil. The extract liquid has a wide source of raw materials, and the preparation method is simple, convenient to popularize, economical and feasible for reducing nitrous oxide emission.

Description

technical field [0001] The invention belongs to the technical field of reutilization of camellia oleifera husks, in particular to a method for preparing camellia oleifera husk extract and using the camellia oleifera husk extract to reduce soil nitrous oxide emission. Background technique [0002] Camellia oleifera husk contains tea saponin, tea seed polysaccharide, tea seed protein, etc. They are all raw materials for chemical industry, fertilizer, light industry, food, feed industry products, etc. Tea seed husk can also be made into furfural, activated carbon, etc. Tea husk It is also a good medium for edible fungi. Studies have shown that camellia saponin also has antibacterial and antioxidant effects. Therefore, most of the studies on camellia oleifera shells focus on extracting polysaccharides and other components in camellia oleifera shells, or use camellia oleifera shells as raw materials to prepare biological fertilizers, deodorants, flame-retardant composite materia...
