Embodiment Construction

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

[0022] Food waste 15, bentonite 6, corn straw 20, nitrification inhibitor DMPP0.7, glucose 1, citric acid 1, peat soil 1, ferrous sulfate 0.5, beet pulp 10, biogas slurry 4, sodium A-naphthalene acetate 1.5, Glyceryl monostearate 1, Solanum nigrum root 1, Snakevine 2, Arabidopsis 3, Trichosanthes 2, Oolong head 2, Burnet 2, Sodium dodecylbenzene sulfonate 0.8.

[0023] The preparation method of the slow-release additive for rice fertilizer comprises the following steps:

[0024] (1) Collect food waste, dehydrate it 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 bentonite, stir and mix well, wash with water to remove surface dust and impurities, mix the resulting mixture with hydrochloric...

Abstract

The invention discloses a rice fertilizer slow-release additive which is prepared from the following raw materials in parts by weight: 10-15 parts of kitchen wastes, 3-6 parts of bentonite, 10-20 parts of corn straw, 0.4-0.7 part of a nitration inhibiter DMPP, 1-2 parts of glucose, 1-2 parts of citric acid, 1-2 parts of peat soil, 0.5-0.8 part of ferrous sulfate, 10-14 parts of beet pulp, 4-6 parts of biogas slurry, 1-1.5 parts of A-sodium naphthalene acetate, 1-2 parts of glycerin monostearate, 1-3 parts of root of solanum nigrum, 2-5 parts of celastrus orbiculatus, 3-4 parts of arabidopsis halleri, 1-2 parts of hedyotis chrysotricha, 1-2 parts of aralia chinensis, and 1-2 parts of sanguisorba officinalis. According to the invention, the kitchen wastes are reasonably utilized, and can be changed into biochar, so that wastes can be changed into wealth, and the utilization problem of the kitchen wastes is solved; traditional Chinese medicine residues generated from traditional Chinese medicine filtrate production are recycled to be fermented, so that the soil hardening and other phenomena can be effectively improved.

Description

technical field [0001] The invention relates to the field of fertilizer additives, in particular to a rice 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] Yellow hair ear grass is a perennial herb that grows o...
