Example Embodiment

[0031] Example 1:

[0032] When applied on kiwi fruit trees, a kind of special fertilizer for fruit trees produced by castor oil meal in parts by weight: 62 parts of castor oil meal, 7 parts of urea, 14 parts of superphosphate, 5 parts of potassium chlorate, 9 parts of compound bacteria residue, synergistic 1 part of agent, 2 parts of adhesive.

[0033] Step 1: Take 62 parts of castor oil meal and 9 parts of composite fungus residue, dry them at a temperature of 50-60°C, grind them, mix them evenly, and pass them through a 50-mesh sieve to obtain material I;

[0034] Step 2: Accurately weigh 7 parts of urea, 14 parts of superphosphate, 5 parts of potassium chlorate, 1 part of synergist, and 2 parts of adhesive, grind them and add them to a mixer to obtain material II;

[0035] Step 3: Feed material Ⅰ and material Ⅱ into the distributor and evenly distribute them in the extrusion granulator, granulate to obtain granules, the particle size is 3.8-4.4mm, if the particle size is ...

Example Embodiment

[0041] Example 2:

[0042] When applied on apple trees, the ratio of special fertilizer for fruit trees is: 61 parts of castor oil meal, 11 parts of urea, 20 parts of superphosphate, 3 parts of potassium chlorate, 5 parts of compound bacteria residue, 2 parts of synergist, adhesive 1 serving.

[0043] Step 1: Take 61 parts of castor oil meal and 5 parts of composite fungus residue, dry them at a temperature of 50-60°C, grind them, mix them evenly, and pass them through a 50-mesh sieve to obtain material I;

[0044] Step 2: Accurately weigh 11 parts of urea, 20 parts of superphosphate, 3 parts of potassium chlorate, 2 parts of synergist, and 1 part of adhesive, grind them and add them to a mixer to obtain material II;

[0045] Step 3: Feed material Ⅰ and material Ⅱ into the distributor and evenly distribute them in the extrusion granulator, granulate to obtain granules, the particle size is 3.8-4.4mm, if the particle size is unqualified, return to the granulator for re-granula...

Abstract

A special fruit tree fertilizer produced from castor oil meal and a preparation process thereof are disclosed. The special fruit tree fertilizer is prepared from the following raw materials in parts by weight: 60-76 parts of castor oil meal, 6-15 parts of urea, 10-25 parts of calcium superphosphate or diammonium phosphate, 3-10 parts of potassium chlorate, 6-10 parts of composite mushroom dreg, 1-3 parts of a synergist and 2 parts of an adhesive. In the fertilizer preparation process, castor oil meal and the other raw materials need to be crushed and then enter a mixer to be uniformly mixed, and then the mixture is packaged by a packaging machine and transported out. The special fruit tree fertilizer produced from castor oil meal provided by the invention is reasonable in organic-inorganicnutrient proportion, conforms to the fertilizer requirement law of fruit trees, and is cheap and easily available in raw materials, simple in preparation process and easy for large-scale production.By utilizing the insecticidal characteristic of the castor oil meal, the product synchronously performs fertilization and pest control, solves the problems of food safety and environmental pollution caused by pesticide use, and provides guarantee for the production of green organic food.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a special fertilizer for fruit trees produced from castor oil meal and a preparation process thereof. Background technique [0002] Castor is an important bioenergy crop, and it is an ideal crop for repairing heavy metal-contaminated soil. Our country is rich in castor resources, because castor has strong adaptability and does not require high soil and cultivation conditions. The annual output is about 200,000 hectares to 300,000 hectares. The residue left after castor bean oil extraction is called castor oil meal. The main components of castor oil meal are: crude protein 34.9%, crude fiber 33.87%, crude fat 7.37%, coarse powder 6.51%, calcium 1.10%, Phosphorus is 0.62%, and the nutritional value of castor oil meal is relatively high. However, because it contains four toxic substances of ricin, ricinine, CB-1A allergen and hemagglutination, it cannot be directly u...
