Description
Technical Field
The invention belongs to the technical field of camellia oleifera planting, and particularly relates to a camellia oleifera slow-release special fertilizer and a preparation method thereof.
Background
Camellia oleifera belongs to Theaceae, and is a evergreen medium and small arbor, also known as tea tree, tea oil tree and white tea. The oil tea fruit can be squeezed into tea oil for eating, the tea oil has clear color, delicious taste, rich nutrition and storage resistance, is high-quality edible oil, and can also be used as lubricating oil, antirust oil and the like. The camellia oleifera is one of four woody oil plants in the world, grows in mountains and hilly lands in subtropical regions in south China, is a specific high-grade natural oil plant in China, is mainly distributed in Zhejiang, Jiangxi, Henan, Hunan, Guangxi and the like, and has the annual yield of only about 20 ten thousand tons in China.
In the existing camellia oleifera planting process, an N/P/K compound fertilizer is generally applied to improve soil fertility, and the root system of a camellia oleifera tree is rotten and burned due to too fast release or excessive application of the compound fertilizer, so that the growth and the yield of the camellia oleifera are seriously influenced. Particularly, in the oil tea seedling stage or the oil tea tree which is just transplanted, as the root system of the oil tea tree grows incompletely, the lignification degree is low, the oil tea tree is young and tender, and when the soil concentration is slightly high, the water loss and atrophy can occur, and the root tissue can be damaged to a certain extent in the transplanting process of the oil tea tree. In addition, the growth period of the camellia oleifera is long, the camellia oleifera starts to fruit in the 3 rd year, the first 5 years are mainly the tree growing stage, the full-bearing period gradually starts in 6-10 years, the slow release fertilizer can continuously provide nutrients capable of being directly absorbed and utilized for the camellia oleifera in the growth process of the camellia oleifera, and compared with quick-acting fertilizers, the slow release fertilizer is not easy to lose fertility and more durable, and can effectively reduce the planting cost of farmers.
