Embodiment 1

[0055] (1) After the agricultural and forestry waste (crop straw) is pretreated, cut and dedusted, it enters the separation section, where hemicellulose, cellulose and lignin are separated by physical and chemical methods, and straw light ash is produced. The separated Hemicellulose is in the liquid phase, that is, hemicellulose liquid.

[0056] (2) The hemicellulose liquid enters the wastewater treatment system, and after the pretreatment stage, the suspended solids are removed to produce primary sludge, and the biochemical treatment stage removes a large amount of soluble COD (chemical oxygen demand) to produce remaining activated sludge and biogas slurry, and the advanced treatment stage Removing a small amount of pollutants that are not easily biodegradable produces chemical sludge.

[0057] (3) The primary sludge, remaining activated sludge and chemical sludge enter the sludge thickening tank and mix evenly to obtain mixed sludge, and then use the principle of gravity sed...

Abstract

The invention specifically relates to an environment-friendly additional fertilizer and a preparation method thereof, belonging to the technical field of agricultural plantation. The environment-friendly additional fertilizer is prepared from the following raw materials: dehydrated sludge, light straw ash, biogas slurry, citric acid, EM probiotic liquid, amino acid and calcium hydrate. The dehydrated sludge, light straw ash and biogas slurry basically retain basic elements like nitrogen, phosphorus and potassium in waste agricultural and forestry raw materials and are rich in organic matters, amino acids, humic acid, B group vitamins, a variety of hydrolases, certain phytohormone, factors exerting inhibitory effect on plant diseases and insect pests and trace elements like calcium, iron, copper, zinc, manganese and molybdenum, so the additional fertilizer has comprehensive nutritional components and is high in utilization rate. In the field of modern organic plantation, the fertilizer provided by the invention can meet demands of crops for considerable nutrients in some periods and overcomes disadvantages of a base fertilizer or seed fertilizer. The preparation method is simple and reasonable and is easy for industrial production.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to an environment-friendly top dressing and a preparation method thereof. Background technique [0002] Material accumulation during crop growth is closely related to nutrient uptake. Topdressing is the application of solid or liquid fertilizers during the growth of crops. Its main purpose is to meet the large demand for nutrients in certain periods of crops and to make up for the shortage of base fertilizer or seed fertilizer. However, in recent years, with the improvement of farmers' living standards, farmers have increasingly ignored the use of organic fertilizers and applied a large amount of chemical fertilizers, resulting in soil structure damage, deterioration of physical and chemical properties, reduced production potential, and fragile ecological environment. And agricultural products are polluted, and agricultural production input increases, whic...
