Embodiment 1

[0030] The straw is crushed twice, and once crushed into 0.5-2cm long debris, the straw debris is put into a corrosion-resistant container, and 2% of 0.5mol / L NaOH solution is added for every 1 ton of straw debris, and at the same time Add 10% water to ensure that the raw materials are fully mixed, and keep at room temperature for 3 hours; add a compound microbial agent for fermentation to the pretreated straw debris raw material container, mix the raw materials evenly, seal them well, and store them in a 10°C Under temperature conditions, carry out fermentation; after high-temperature disinfection and sterilization, mix the above-mentioned fermented debris with peat, fly ash, bentonite, diammonium hydrogen phosphate, and sepiolite, dry, and grind into powder with a particle size of 40 mesh Standby; add ammonium bicarbonate, amino acid fertilizer, and compound microbial agent for soil improvement to the powder base material and mix to make raw materials; add an appropriate amou...

Embodiment 2

[0032] The straw is crushed twice, once crushed into debris with a length of 0.5-2cm, put the straw debris into a corrosion-resistant container, and add 3.5% of 0.5mol / L NaOH solution per 1 ton of straw debris, and at the same time Add 15% water to ensure that the raw materials are fully mixed, and keep at room temperature for 3 hours; add the compound microbial agent for fermentation to the pretreated straw debris raw material container, mix the raw materials evenly, seal them well, and store them in a 30°C Under temperature conditions, carry out fermentation; after high-temperature disinfection and sterilization, mix the above-mentioned fermented debris with peat, fly ash, bentonite, diammonium hydrogen phosphate, and sepiolite, dry, and grind into powder with a particle size of 40 mesh Standby; add urea, amino acid fertilizer, and compound microbial agent for soil improvement to the powder base material and mix to make raw materials; add an appropriate amount of bentonite, a...

Embodiment 3

[0034] The straw is crushed twice, once crushed into debris with a length of 0.5-2cm, put the straw debris into a corrosion-resistant container, and add 3.5% of 0.5mol / L NaOH solution per 1 ton of straw debris, and at the same time Add 15% water to ensure that the raw materials are fully mixed, and keep at room temperature for 3 hours; add the compound microbial agent for fermentation to the pretreated straw debris raw material container, mix the raw materials evenly, seal them well, and store them in a 30°C Under temperature conditions, carry out fermentation; after high-temperature disinfection and sterilization, mix the above-mentioned fermented debris with peat, fly ash, bentonite, diammonium hydrogen phosphate, and sepiolite, dry, and grind into powder with a particle size of 40 mesh Standby; add urea, amino acid fertilizer, and compound microbial agent for soil improvement to the powder base material and mix to make raw materials; add an appropriate amount of bentonite, a...

Abstract

The invention relates to a phosphorus-solubilizing and potassium-solubilizing and nitrogen fixing organic functional fertilizer obtained by means of straw fermentation. The fertilizer is prepared from the following components in parts by weight: 100 parts of straw chips, 0.03-0.04 part of a compound microbial agent for soil improvement, 05-2.0 parts of phosphate, 6-12 parts of coal ash, 5-10 parts of sepiolite, 5-15 parts of peat and 5-12 parts of bentonite. The fertilizer provided by the invention has the technical effects that (1) the straw raw material is pre-treated by using alkaline substances, so that the straw raw material is easier to ferment subsequently, and the fermentation efficiency is improved; and (2) a special microbial flora is adopted for compatibility, so that the fermentation efficiency is improved; the overall fermentation process can be completed by primary fermentation without conventional secondary or even third fermentation, so that the unexpected technical benefits and remarkable progress are gained. Therefore, the time and cost are greatly saved, the craft process is simplified, and the fertilizer is convenient to popularize and use, so that the economic benefit is improved.

Description

technical field [0001] The invention relates to a process for preparing organic fertilizers, in particular to a process for making organic fertilizers through comprehensive utilization of straw, which belongs to the field of fertilizers. Background technique [0002] Organic fertilizers have comprehensive nutrients and long-lasting fertilizer effects. They can improve soil structure, fertilize soil fertility, and promote the release of soil nutrients. It is of great significance to improve the quality of agricultural products and produce pollution-free, green and organic agricultural products. However, the direct application of organic fertilizers that have not been fully fermented and decomposed usually causes great harm: ① Infection of diseases and insect pests. It is easy to breed bacteria and insects, leading to the occurrence of crop diseases and insect pests; ② Burning seedlings or roots. After the unfermented organic material is applied to the field, when the ferment...
