Tea-saponin-extracted Camellia oleifera cake meal residue organic fertilizer and preparation method thereof

Abstract

The invention discloses a composting technology of a tea-saponin-extracted Camellia oleifera cake meal residue organic fertilizer, wherein the components comprise: 60-80% of Camellia oleifera cake meal, 15-30% of pig manure, 5-10% of rice straw, 3-8% of rice husk, and 1-2% of a fermenting bacterial agent, wherein the water content is adjusted to 60-70%, and a carbon to nitrogen ratio is controlledat 24:1-30:1. According to the present invention, the waste raw materials of Camellia oleifera are recovered, no pollution is generated to the environment, the soil and the plants, the reuse of the waste in the Camellia oleifera enterprise is achieved, the novel bio-organic fertilizer is provided, and the utilization rate of resources is increased.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer fermentation, and mainly relates to an organic fertilizer of camellia oleifera cake after extracting tea saponin and a preparation method thereof. Background technique [0002] Camellia oleifera is one of the four largest woody oil plants in the world. my country is the country with the widest distribution of camellia plants in the world. Camellia oil is one of the oldest woody edible vegetable oils in China. It has a table history of more than 2,000 years. There is "Oriental olive oil" " and "treasures in oil". In recent years, tea oil has been favored by more and more consumers, and the production and sales prospects are very promising. In 2015, my country had a total area of ​​3.8217 million hectares of Camellia oleifera forests, 2,208 Camellia oleifera-related enterprises, 2.1635 million tons of Camellia oleifera seeds, and an annual output of 500,000 tons of Camellia oleifera.

AI Technical Summary

Problems solved by technology

Camellia oleifera cake is the residue after oil-pressing of camellia oleifera seeds, with an average annual output of about 1.5 million tons. Fresh cake generally contains 5-7% residual oil, 12-16% protein, and 40-50% starch. The cake also contains 8-10% tea saponin, about 2% tannin and about 0.4% caffeine. It tastes spicy, so it has poor palatability and cannot be used as feed for higher vertebrates.

Camellia oleifera cake is usually sold as waste residue at a low price, resulting in an increase in the cost of tea seed oil and a decrease in market competitiveness

[0003] Camellia oleifera cake is generally used as the raw material for extracting tea saponin, and the residue after extraction is basically discarded or directly used as fuel. Even if it is used directly as fertilizer, the fertility is weak due to insufficient nutrients, resulting in a large amount of resources. waste
