Abstract

The invention relates to a long-acting special fertilizer for oil-tea camellia and a preparation method thereof. The long-acting special fertilizer is characterized in that: the fertilizer is prepared from the following raw materials in percentage by weight: 31.3 to 42.9 percent of nitrogen fertilizer, 8.5 to 8.7 percent of phosphate fertilizer, 26.7 to 32.0 percent of potassic fertilizer, 2.6 to 5.1 percent of medium-micro fertilizer, 10 to 15 percent of organic additive and 4 to 19.4 percent of controlled release additive. The special fertilizer for the oil-tea camellia is produced according to the absorption characteristics of the oil-tea camellia on N, P and K, is suitable for the absorption of N, P and K by the oil-tea camellia, has reasonable proportion and long fertilizer efficiency period, can be used as base fertilizer and additional fertilizer, has high nutrient utilization rate, and is safe and environment-friendly; the special fertilizer can remarkably improve the utilization rate of nitrogen, the increasing range is over 8 percent, and the fertilizer efficiency period is as long as 90 to 150 days; and under the same nutrient condition, the special fertilizer can increase the yield of oil-tea camellia fruits by about 10 percent, can remarkably promote the quality of the oil-tea camellia fruits, and promotes the oil content by over 0.6 percent.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a long-acting special fertilizer for camellia oleifera and a preparation method thereof. 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 th...
