Soil improvement fertilizer as well as preparation method and application thereof

Abstract

The invention discloses a soil improvement fertilizer as well as a preparation method and application thereof, the method comprises the following steps: uniformly mixing turf, rapeseed meal, sterilized bone meal, peptone, humic acid and potassium fulvate, and adding EM flora and bacillus subtilis to obtain a to-be-fermented material; uniformly spraying a brown sugar water solution with the mass concentration of 0. 4% into the to-be-fermented material for fermentation to obtain a fermentation product; adding amino acid, bone-prepared calcium hydrogen phosphate, monopotassium phosphate, potassium sulfate, water-soluble monoammonium phosphate, ammonium sulfate and urea into the fermentation product to obtain a mixed product; and crushing the mixed product, adding trace elements and bacillus subtilis, stirring and mixing uniformly to obtain the soil improvement fertilizer; and the soil improvement fertilizer can be used for improving and repairing soil of wolfberries and preventing and treating root rot. The improved fertilizer disclosed by the invention can meet basic requirements for nutrients in different growth stages of the wolfberries, and promotes the good development of the soil in a wolfberry planting area, the raw materials are all-water-soluble, and the preparation method is suitable for flushing and micro-drip irrigation, is convenient, saves energy and is efficient.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a soil improving fertilizer, a preparation method of the soil improving fertilizer and the application of the soil improving fertilizer in improving and repairing soil and preventing and controlling root rot. Background technique [0002] Lycium barbarum is an important special economic plant resource for both medicine and food in my country. It has been cultivated for thousands of years. It has been industrialized in various degrees in many northern provinces. Among them, the most famous one is Ningxia wolfberry. In recent years, Qinghai wolfberry industry has developed. Rapidly, the planting area has reached nearly 600,000 mu. Qinghai wolfberry (mostly known as "Chai Qi") is mainly distributed in Dulan, Delingha, Golmud, Ulan and other areas in the Qaidam Basin. The production area is located in one of the "four ultra-clean areas" in the world. In the hinterland...

Problems solved by technology

[0004] Lycium barbarum is a perennial shrub belonging to the family Solanaceae Lycium barbarum. It is impossible to achieve the purpose of improving soil through crop rotation, no matter in terms of economic, medicinal value or ecological environment value. The proportion of organic manure and farmyard manure in wolfberry planting is gradually increasing. However, due to the ecological fragility of the planting area, the short suitable growth period, and poor soil (take the soil in Nuomuhong, Qinghai as an example, according to the second national soil census grading standard, except for quick-acting Phosphorus is grade 4, and the rest of the indicators are grade 6), and the application of farmyard manure alone cannot fully meet the needs of crop growth, affecting yield and quality, while the application of organic fertilizer and adding soil improvement products increases labor, time and economic costs for farmers, making it difficult to popularize and apply

In addition, existing soil improvement products are either soil or crop-specific, or widely applicable, lacking pertinence and effectiveness for wolfberry cultivation
