High-potassium organic composite fertilizer special for dragon fruit and production method using domestic sludge

Abstract

The invention discloses a high-potassium organic composite fertilizer special for dragon fruit, and a production method using domestic sludge. The organic composite fertilizer is characterized by being prepared from the following components: urban domestic sludge, chicken excrement, mushroom residue and plant ash, wherein the content of total organic substances in the raw material formula is more than or equal to 45%; the urban domestic sludge refers to dirt discharged from urban sewage treatment plants or large food factories after wastewater treatment; the moisture content of the urban domestic sludge is less than 60%; and the mushroom residue refers to residue of pleurotus eryngii or seafood mushroom cultivated in factories. The organic composite fertilizer can be used as a novel organic composite fertilizer which is used as a high-potassium organic fertilizer to be used by planting farmers for cultivating high-quality dragon fruit, is beneficial for improving the urban domestic sludge utilization rate, is beneficial for the environment and can reduce the production cost.

Description

technical field [0001] The invention relates to an organic fertilizer production technology, in particular to a special organic compound fertilizer for high-potassium dragon fruit and a method for producing it using domestic sludge. Background technique [0002] Pitaya is a perennial tropical and subtropical fruit of the cactus family. Its fruit is rich in vitamins, amino acids, and minerals necessary for the human body. It has the effects of lowering blood pressure, blood fat, and blood sugar, and is favored by consumers; It has the characteristics of drought tolerance, strong resistance to diseases and insect pests, high yield, good economic value and ecological benefits; dragon fruit has a large demand for potassium as a high-potassium plant, and potassium is the main element that determines quality, but the quality and yield of dragon fruit are easily affected by the soil. Influenced by many factors such as fertility and fertilizer application, it is necessary for grower...

Problems solved by technology

[0003] In addition, as we all know, urban domestic sludge is the sewage discharged from urban sewage treatment plants or large-scale food factories (such as monosodium glutamate and other food factories). Due to the lack of effective treatment methods, the sludge often pollutes the environment when it is discharged. Because these sludges contain a certain amount of harmful substances and the water content is as high as 80-95%, they cannot be directly used as fertilizers, but the sludge is also rich in nutrients such as nitrogen, phosphorus, and potassium. Therefore, urban life after harmless treatment Sludge is a good organic fertilizer raw material
