Special balanced-nutrient fertilizer for oil tea whole growth period

Abstract

The invention discloses a special balanced-nutrient fertilizer for the oil tea whole growth period. The fertilizer is prepared from the following raw materials in parts by weight: 18-22 parts of potassium sulfate magnesium fertilizer, 10-25 parts of ammonia water, 15-35 parts of calcium nitrate, 0.5-1 part of organobentonite, 1.5-2.5 parts of fly ash, 0.5-1 part of zinc chloride, 3-7 parts of attapulgite clay, 4-8 parts of dolomite powder, 2-5 parts of kaolin, 1.5-2.5 parts of corn straw, 6-12 parts of pig viscera, 4-12 parts of coating agent, 15-35 parts of bone slag, 10-20 parts of fermented peanut pulp, 0.4-1 part of composite bacterium, 1.5-2.5 parts of clay and 1.5-2.5 parts of fatty acid monoglyceride. The fertilizer can be matched with the oil tea growth regulation nutrient release rate, has favorable slow-release effects, is suitable for the demands of oil tea for the nutrients in the whole growth period, can improve the soil structure and soil permeability, effectively improves the coating hardness and toughness, and can not be easily dispersed or easily crack under the condition of certain humidity.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for the whole growth period of Camellia oleifera with balanced nutrition. 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 affe...
