Fertilizer based on oil-tea camellia cattail, preparation method and application thereof

The present invention belongs to the technical field of biomass resource utilization and microbial fertilizers, and specifically relates to a fertilizer based on oil-tea camellia cattail, a preparation method and its application. The fertilizer described in the present invention is prepared by a collaborative fermentation process of Aspergillus niger, Phanerochaete chrysosporium and Bacillus subtilis. The obtained fermentation product is separated into solid and liquid to obtain a solid, the solid being a solid fertilizer, and the liquid being a foliar fertilizer after post-treatment. Both can be used for the cultivation of crops such as tangerines and oil-tea camellias. Based on the microbial collaborative fermentation process, the content of anti-nutritional factors tannin and tea saponin in the obtained solid fertilizer is significantly reduced, which is less than 1.8 g / kg and 0.1% respectively on a dry basis, while maintaining a seed germination index higher than 95%. According to a planting comparative test, the average yield per mu of oil-tea camellias using the solid fertilizer and liquid fertilizer obtained in this application increased by 12%. The average yield per mu of tangerines increased by about 11%, and the sugar, vitamin C, and trace element contents in tangerines were higher than those using traditional fertilizers.
