Embodiment Construction

[0021] A kind of eucalyptus fertilizer slow-release additive, it is made by the raw material of following weight (kg):

[0022] Straw 25, Zeolite Powder 16, Clay 1, Aminothiourea 1, Betaine 1, Soluble Chitosan 1, Fulvic Acid 2.8, Pig Manure 20, Rapeseed Cake Powder 4, Corn Flour 2, Polyacrylamide 2, Aracea 1. Sophora flavescens 1, perilla stalk 1, castor root 2.

[0023] Described a kind of eucalyptus fertilizer slow-release additive, preparation method comprises the following steps:

[0024] (1) Collect crop stalks, dry them to make the water content less than 20%, then conduct pyrolysis carbonization at 500°C, cool, grind, and pass through a 1mm sieve to obtain biochar with a particle diameter of <1mm;

[0025] (2) After sieving the biochar, mix it with zeolite powder, stir and mix well, wash with water to remove surface dust and impurities, and mix the resulting mixture with hydrochloric acid solution with a concentration of 5-8% at a mass ratio of 1:2 , and then soaked a...

Abstract

The invention discloses a slow-release additive for a fertilizer of eucalyptus. The slow-release additive is prepared from the following raw materials in parts by weight: 20-25 parts of straw, 14-16 parts of zeolite powder, 1-2 parts of clay, 1-2 parts of guanylthiourea, 1-2 parts of glycine betaine, 1-4 parts of soluble chitosan, 1.4-2.8 parts of fulvic acid, 20-30 parts of pig manure, 4-8 parts of rape seed cake, 1-2 parts of maize meal, 1-2 parts of polyacrylamide, 0.5-1 part of rhizoma arisaematis, 1-2 parts of radix sophorae flavescentis, 1-2 parts of caulis perillae and 1-2 parts of castor root. According to the slow-release additive for the fertilizer of eucalyptus, provided by the invention, positive ions in cavities and channels have a higher selective ion-exchange property, heavy metal ions and cyanide harmful to animals can be removed, and beneficial metal ions are enabled to be released.

Description

technical field [0001] The invention relates to the field of fertilizer additives, in particular to a eucalyptus fertilizer slow-release additive. Background technique [0002] For a long time, my country's chemical fertilizer application has the disadvantages of excessive application, nutrient loss, and low utilization rate of crops. Only 30% of the chemical fertilizers used in traditional agricultural production are absorbed by crops, and the rest are volatilized into the atmosphere or lost with water and soil, causing a large number of The loss of fertilizer also caused some pollution to the environment. [0003] Fertilizer additives, chemicals used to improve fertilizer performance, enhance fertilizer efficacy, decompose residual pesticides, nitrates, and improve the soil environment. Existing fertilizer additives have a single function and cannot fully meet the various requirements of various plant growth soils. [0004] Zeolite is a framework-like aluminosilicate mine...
