Problems solved by technology

The disadvantages of these two application methods are: because only fulvic acid dissolves humic acid under acidic and neutral conditions, black humic acid and brown humic acid contained in humic acid cannot be dissolved, resulting in low utilization rate of humic acid
[0009] After extensively consulting open publications and patent documents at home and abroad, there is no sodium silicate humic acid rice organic-inorganic compound fertilizer identical to the present invention; there is no sodium silicate humic acid identical to the present invention. Preparation method of rice organic-inorganic compound fertilizer

Embodiment 1

[0037] According to the method of prior art, get 81 tons altogether of urea, diammonium phosphate, potassium sulfate, 12 tons of plant stalk fermentation product, be mixed with the compound fertilizer raw material of 43.5% containing nitrogen, phosphorus and potassium; Add 5 tons of humic acid, stir and mix Evenly, transported to the compound fertilizer production line. Take 2 tons of sodium silicate and mix it with 2 tons of water to form a sodium silicate aqueous solution; during the granulation process of the above raw materials, evenly spray it into the drum granulator to make sodium silicate humic acid containing 40% nitrogen, phosphorus and potassium Rice organic-inorganic compound fertilizer is bagged after screening and weighing.

[0038] The fertilizer of the present invention is combined with soil preparation before rice transplanting, and is applied to the field at a rate of 25 kilograms per mu.

Embodiment 2

[0040] According to the method of prior art, get 81 tons altogether of urea, diammonium phosphate, potassium sulfate, 12 tons of plant stem fermentation product, be mixed with the compound fertilizer raw material containing 33% of nitrogen, phosphorus and potassium; Add 5 tons of humic acid, stir and mix Evenly, transported to the compound fertilizer production line. Take 2 tons of sodium silicate and mix it with 2 tons of water to form a sodium silicate aqueous solution; during the granulation process of the above raw materials, evenly spray it into the drum granulator to make sodium silicate humic acid containing 30% nitrogen, phosphorus and potassium Rice organic-inorganic compound fertilizer is bagged after screening and weighing.

Embodiment 3

[0042] Get 25 kilograms of fertilizers prepared in Example 2, mix with 10 kilograms of urea, and 10 kilograms of diammonium, before rice transplanting, combined with site preparation, apply to one mu of field, yielding 710 kilograms of rice per mu. In the control field, 25 kg of humic acid rice organic-inorganic compound fertilizer containing 30% of nitrogen, phosphorus and potassium, 10 kg of urea, and 10 kg of diammonium were applied, and the yield of rice per mu was 645 kg, an increase of 10%.

Abstract

The invention belongs to a rice organic-inorganic compound fertilizer, in particular to a rice organic-inorganic compound fertilizer containing sodium silicate and humic acid and a preparation method thereof. In the prior art, the defect of low utilization ratio of the humic acid exists since the humic acid is directly applied to soil. The rice organic-inorganic compound fertilizer consists of the following substances in parts by weight: 93 parts of an organic matter-nitrogen-phosphorus-potassium raw material fertilizer, 5 parts of the humic acid and 2 parts of the sodium silicate. The preparation method of the fertilizer comprises the following steps: adding 5 parts of the humic acid into 93 parts of the organic matter-nitrogen-phosphorus-potassium raw material fertilizer, smashing, stirring and mixing the two materials, and feeding the mixture into a granulator; adding 2 parts of the sodium silicate into 2 parts of water for diluting, and spraying the diluted sodium silicate into the fertilizer raw materials in the granulator; granulating the mixture; and sieving, weighing and packing the mixture. The rice organic inorganic compound fertilizer has the advantages that the utilization ratio of the humic acid is increased; the biological activity of the humic acid increased; the rice yield is increased; soil acidification and hardening, fertility decline and heavy metal enrichment in rice fields are retarded effectively; the pelletizing rate of the organic fertilizer is increased; and the production energy consumption is saved, and the production cost is lowered.

Description

technical field [0001] The invention belongs to rice organic-inorganic compound fertilizer, in particular to a rice organic-inorganic compound fertilizer containing sodium silicate humic acid and a preparation method thereof. Background technique [0002] In modern agricultural production, due to the long-term use of large amounts of inorganic fertilizers in rice production, the stress resistance of rice has been reduced, such as resistance to diseases and insect pests, lodging resistance, cold resistance, and drought resistance, etc., resulting in increased pests and diseases, reduced rice production and rice quality; Acidification and compaction are caused, and soil fertility is reduced; at the same time, the enrichment of heavy metals in fertilizers also causes food safety hazards. In order to solve the food safety problems caused by soil acidification, compaction, fertility decline, and heavy metal enrichment in paddy fields, people not only increase soil organic matter,...
