Organic fertilizer for agricultural planting and preparation method thereof

Abstract

The invention provides organic fertilizer for agricultural planting and a preparation method thereof. The organic fertilizer is prepared from base fertilizer, crop stalk, livestock excrement, ammoniachloride, agricultural rare earth, plant ash, bentonite powder, new precipitation metatitanic acid, selenium ore active powder, citric acid, biological bacteria, shell powder, candy pomace, regulatorand deionized water. The prepared organic fertilizer is suitable for crop growth, water loss and evaporation in soil can be reduced, drought pressure can be relieved, fertilizer can be maintained, chemical fertilizer can be reduced, salt and alkali damage can be relieved, on the condition that chemical fertilizer consumption is reduced or chemical fertilizer is replaced step by step, the soil fertility is improved, the crop agricultural character can be improved, crop stems are thick and solid, the leaf color is dark green, blooming is achieved in advance, the disease resistance and stress resistance of crops are enhanced, and diseases and soil transfer diseases caused by crop continuous cropping are relieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an organic fertilizer for agricultural planting and a preparation method thereof. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvesting seeds. It is a multi-purpose renewable biological resource. People's most direct impression of straw treatment is that it is burned in large quantities in the field. It makes people suffocate, and airport shutdowns and highway closures caused by straw burning occur from time to time, and the losses are incalculable. Therefore, the method of returning straw to the field is generally used to deal with straw. [0003] However, the existing straw returning technology uses mechanical methods to turn over the field and crush the cultivated l...

Problems solved by technology

Although the fertilizer prepared by this method has dual effects of improving soil and slowing the release of fertilizer, it also has too single composition, resulting in insufficient nutrient content of the fertilizer and less benefit to crop cultivation.
