Composite fertilizer for improving quality and output of tea trees, and production method thereof

Abstract

The invention discloses a composite fertilizer for improving the quality and the output of tea trees, and a production method thereof. Raw materials of the composite fertilizer comprise an inorganic fertilizer, organic matters, middle elements, trace elements, a fertilizer activator and a pest repellant; and the composite fertilizer concretely comprises 25wt% or above of total nutrients (N+P2O5+K2O), 15wt% or above of the organic matters, 0.1-0.6wt% of the middle elements, 0.05-0.6wt% of the trace elements, 0.04-0.1wt% of the fertilizer activator and 0.05-10wt% of the pest repellant, wherein the above weight percentages of above components are represented according to GB18877-2009 organic-inorganic compound fertilizer national standards). The composite fertilizer for improving the quality and the output of tea trees has nitrogen fixation, phosphorus activation and potassium releasing effects, contains middle and trace elements, timely supplements nutrition needed in the growth process of tea trees, can increase the content of the organic matters in soil and improve environment of soil, has a pest approaching avoidance effect, allows the tea trees fertilized with the composite fertilizer to have good growth vigor, improves the quality, improves the output by 15% or above, and substantially improves the economic benefit.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and in particular relates to a special fertilizer for tea trees and a production method thereof. Background technique [0002] tea tree( Camellia sinensis ), belonging to the Theaceae Camellia genus, is a perennial evergreen woody plant, generally a shrub, and there are also arbor-type tea trees in tropical areas with a height of 15-30 meters and a base tree circumference of more than 1.5 meters. In cultivation and management, the longitudinal growth of tea trees is often suppressed by pruning, so the tree height is relatively high, generally between 1.0 and 1.5 meters; the leaves of tea trees are oval, with serrated edges, and five-petal white flowers bloom between the leaves. Oblate and triangular in shape, the seeds are exposed after the fruits are laid out. The young leaves of the tea tree can be picked in spring and autumn every year to make tea. At the same time, other organs of the tea tr...

Problems solved by technology

[0009] The object of the present invention is to provide a compound fertilizer and a production method thereof for improving the quality and yield of tea trees. The proportioning content of nitrogen, phosphorus and potassium is reasonable, and contains organic matter, medium and trace element fertilizers, and simultaneously contains fertilizer activators and pest repellents. On the basis of providing various nutrient elements, it can also fix nitrogen, activate phosphorus, and dissolve potassium, and at the same time avoid underground pests, so as to overcome the shortcomings of the existing technology such as weak functionality and unreasonable nutritional components.
