Fertilizing method

Abstract

The invention relates to a fertilizer for mature citrus trees. The fertilizer for citrus trees comprises the following raw materials in parts by weight: 30-70 parts of nitrogenous fertilizer, 25-50 parts of potash fertilizer, 10-20 parts of phosphatic fertilizer, 2.5-5 parts of boric fertilizer, 2-7 parts of calcium, 8-25 parts of farmyard manure, 0-6 parts of lime and 0.5-8 parts of fermentation oil cake. The amount of each ingredient in the fertilizer is determined according to the demands of the mature citrus trees at each stage; the fermentation oil cake is taken as a cake residue after rapeseeds are squeezed into oil; the cake residue is watered to form paste, so as to obtain the fermented oil cake by fermentation; the cake residue contains a plurality of nutrient elements. By adopting the fertilizer, the chemical fertilizer, the farmyard manure and the fermented oil cake are combined, and fertilization is carried out by adopting different fertilizer ratios according to the requirements of the citrus trees at different stages, so that the citrus trees obtain enough nutrients to grow; in addition, the fertilization method and the fertilization amount are reasonable, and the fertilizer has an important application prospect.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a fertilizer for mature citrus trees and a fertilization method. Background technique [0002] Citrus genus Rutaceae Citrus subfamily is a tropical and subtropical evergreen fruit tree (except Hovenia trifoliata), and there are 3 genera used for economic cultivation: Hovenia citrus, Citrus and Kumquat.
