Abstract

The invention provides a preparation method of a slow controlled release fertilizer for flowering peach. The method includes the steps of adding urea, sodium citrate and humic acid to water, adjusting pH to 8.0-9.0, adding a formaldehyde solution, adding oxidized starch and hydrogenated vegetable oil, adjusting pH to 4.0-5.0, adjusting pH to 6.0-7.0 to obtain a mixture A, adding sodium alginate and gelatin to water, adding potassium nitrate, diammonium hydrogen phosphate, magnesium sulfate heptahydrate, vitamin B, nicotinamide, amino acid, corn flour, chitosan and lecithin to be mixed to obtain a mixture B, adding the mixture B to the mixture A to be dispersed, adding glutaraldehyde, raising the temperature to 45-55 DEG C, keeping the temperature for 2-4 h, lowering the temperature to 0-5 DEG C, and conducting filtering to obtain the slow controlled release fertilizer. The slow controlled release fertilizer can effectively increase the flowering number of flowering peach, is small in consumption, saves fertilizer applying cost, and improves the ornamental economic benefits of flowering peach.

Description

technical field [0001] The invention belongs to the technical field of plant fertilizers, and in particular relates to a preparation method of a slow-controlled release fertilizer for green peaches. Background technique [0002] Peach belongs to the genus Prunus in the family Rosaceae. It is a peach tree variety for ornamental purposes. It has the characteristics of large flowers, many petals, beautiful flower shapes, rich flower colors, and a long flowering period. Green peach is produced in my country, distributed in North China, Central China, Southwest China and other places, and cultivated all over the world.
