The invention discloses a special fertilizer for carbon-based and selenium-rich tea. The fertilizer is composed of the following raw materials by weight parts: 22-25 parts of biological black carbon, 35-40 parts of urea, 14-16 parts of ammonium dihydrogen phosphate, 16-20 parts of potassium chloride, 4-6 parts of a binder, 1-2 parts of bone meal, 0.2-0.4 parts of ammonium sulfate, and 0.1-0.2 parts of attapulgite. According to the invention, increasing of soil carbon sequestration and organic carbon are obvious, wherein carbon-based carbon sequestration effects are obvious; due to chemical and microbiological inertia of the biological black carbon and physical protection of soil aggregates, the biological black carbon becomes inert carbon pool of the soil, only 5 % of the carbon are re-released into the atmosphere through effects of soil microbe, and 95 % of the carbon are fixed by the soil, thereby generating net carbon absorption; and a fixed time of the biological black carbon in the soil can be hundreds years. A content of soil organic matters can be increased in a short period through turning over of green manure for tea garden soil and application of organic manure, however, a decomposition period is only a few months, and an improvement for the content of the soil organic matters is far lower than the improvement by the biological black carbon. The tea special fertilizer applied with the biological black carbon as an adsorbent can substantially improve the content of soil organic matters and nutrient accumulation.
