Problems solved by technology

[0002] In my country, the unreasonable application of traditional inorganic fertilizers has caused more and more serious pollution problems to surface and groundwater resources, agricultural products, etc., posing a threat to China's human and animal drinking water and food security.
In addition, the low utilization rate of traditional inorganic fertilizers is a common problem in the use of chemical fertilizers
At present, the seasonal utilization rate of chemical fertilizers in my country is low: nitrogen is 30%-35%, phosphorus is 10%-20%, potassium is 30%-35%, and the loss of nitrogen is particularly serious, causing direct economic losses.

[0037] S2: Put the tradit...

Embodiment 2

[0041] Example 2 Preparation of superabsorbent resin

[0042] A kind of superabsorbent resin of compound fertilizer, its preparation method is:

[0043] Polyethylene glycol dimethacrylate is dissolved in water, the amount of water used for 1.2g polyethylene glycol dimethacrylate is 20.0ml, ammonium persulfate is dissolved in water, and the amount of water used for every 0.4g ammonium persulfate is 12.0ml, put 30g acrylic acid monomer and 20g 2-acrylamido-2-methylpropanesulfonic acid monomer into the reactor, add the previously prepared polyethylene glycol dimethacrylate aqueous solution and ammonium persulfate aqueous solution Also added to the reactor, heated to 70°C in a water bath for 6 hours to generate a transparent elastic substance, the transparent elastic substance was taken out from the reactor, cut into pieces, dried at 70°C for 7 hours, and stored after cooling. Can.

Embodiment 3

[0045]Expose 3.2kg of wheat straw to the sun for 10 days to obtain plant straw with a moisture content of no more than 10%, put it into a pulverizer for crushing, and obtain straw particles with a particle size of 1-2cm. Add 3.5kg of chicken manure to the Stack outdoors layer by layer into a compost heap with a width of 2 meters and a height of 2 meters. Fermentation is carried out under loose and ventilated conditions. When the temperature of the compost rises to 70°C, the compost continues for 4 days. Carry out the crushing operation, the particle diameter of the crushed solid particles shall not exceed 0.3cm, mix and mix the treated chicken manure, wheat straw, distiller's grains 1.3kg and humic acid 1kg, and control the pH value at 6; The mixture is fermented with wet materials in the fermentation tank. The bottom of the fermentation pile is 4 meters wide and 3 meters high. Turn the pile for the first time when the inner center temperature exceeds 65°C, and turn the pile o...

Abstract

The invention discloses a compound fertilizer and a preparation method thereof. The compound fertilizer comprises the following raw materials in parts by weight: 10-16 parts of grain stillage, 5-8 parts of citric acid, 28-34 parts of plant straws, 8-12 parts of humic acid, 15-23 parts of urea, 3-6 parts of diammonium phosphate, 6-10 parts of potassium sulfate, 1-3 parts of hydroxyethyl cellulose, 32-38 parts of animal feces, 1-3 parts of super absorbent resin and 4-6 parts of a fertilizer additive. As the super absorbent resin absorbing water will form an island structure, residual water and fertilizer become stored water and fertilizer restrained in a network, so that necessary water, nutritional components and trace elements can be slowly provided for growth of crops for a long time; the used fertilizer additive is prepared from pure traditional Chinese medicine raw materials, so that the toxic effect of the medicines is reduced while the effect of the additive is maintained. By means of a method of evaporating first and then decocting, the pesticide effect can be exerted persistently.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a compound fertilizer and a preparation method thereof. Background technique [0002] In my country, the unreasonable application of traditional inorganic fertilizers has caused more and more serious pollution problems to surface and groundwater resources, agricultural products, etc., posing a threat to China's human and animal drinking water and food security. In addition, the low utilization rate of traditional inorganic fertilizers is a common problem in the use of chemical fertilizers. At present, the seasonal utilization rate of chemical fertilizers in my country is low: 30%-35% for nitrogen, 10%-20% for phosphorus, and 30%-35% for potassium. The loss of nitrogen is particularly serious, causing direct economic losses. [0003] For the planting of crops, compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical proper...
