Slow-release fertilizer for oil-tea tree in whole growth period

Abstract

The invention discloses a slow-release fertilizer for an oil-tea tree in a whole growth period. The slow-release fertilizer comprises the following raw materials by weight: 10 to 30 parts of ammonium nitrate, 5 to 20 parts of ammonium chloride, 10 to 18 parts of potash magnesium sulphate fertilizer, 2 to 10 parts of a coating agent, 10 to 30 parts of animal manure, 5 to 15 parts of a bean cake, 2 to 10 parts of pond mud, 1 to 2 parts of China fir charcoal, 2 to 6 parts of dolomite dust, 1 to 5 parts of gypsum, 1 to 3 parts of kaolin, 1 to 2 parts of sodium silicate, 0.1 to 0.6 part of borax, 0.2 to 0.8 part of calcium carbonate, 1 to 2 parts of maize starch, 1 to 2 parts of soyabean lecithin and 0.1 to 0.6 part of compound bacteria. The slow-release fertilizer can adjust the releasing speed of nutrients in accordance with the growth of the oil-tea tree, has good slow release effect, meets demands of the oil-tea tree for nutrients in the whole growth period, is capable of improving soil structure and soil permeability and efficiently enhancing the hardness and toughness of a coating, and is not prone to dispersion and fragmentation under the condition of certain humidity.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release fertilizer for the whole growth period of camellia oleifera. Background technique [0002] Camellia oleifera is an important southern woody oil tree species in my country and one of the four largest woody edible oil source tree species in the world. Camellia oil is not only edible oil, but also health food; by-products such as tea seed cake and fruit shell are various industrial raw materials; camellia oleifera is a good tree species for landscaping and beautifying barren hills. Although Camellia oleifera has a long history of cultivation in my country, there are phenomena such as unreasonable amount of fertilization, unbalanced fertilization ratio, and insufficient replenishment of restrictive nutrient elements in the fertilization of Camellia oleifera trees. Excessive or insufficient fertilization in Camellia oleifera forests seriously affects the growth and ...
