Dragon fruit-purposed high-potassium organic fertilizer prepared from domestic sludge and fowl manure and production method thereof

Abstract

The invention discloses a dragon fruit-purposed high-potassium organic fertilizer prepared from domestic sludge and fowl manure. The dragon fruit-purposed high-potassium organic fertilizer is characterized by being prepared from the main raw materials including urban domestic sludge and fowl manure; and the special formula specifically comprises the following raw materials: urban domestic sludge, fowl manure, straw, plant ash, pig manure or cow dung and greater than or equal to 45% of organic matters, wherein the urban domestic sludge is the dirt discharged after wastewater treatment of an urban sewage treatment plant or a large food factory; after airing, the water content is 50-60%; and the water content of the pig manure or cow dung after airing is 50-60%. The fertilizer disclosed by the invention is a high-quality high-potassium organic fertilizer to be used as a novel organic compound fertilizer for cultivating high-quality dragon fruit by the growers, and is favorable for improving the utilization rate of urban domestic sludge to promote environmental protection and for reducing the production cost.

Description

technical field [0001] The invention relates to an organic fertilizer production technology, in particular to a high-potassium dragon fruit special organic fertilizer using domestic sludge and chicken manure (main raw materials) and a production method thereof. 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.

[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 growers to frequently increase the content of potassium in fertilizers to improve yield and quality; Choose to use the special organic fertilizer for dragon fruit made of decomposed chicken manure (or cow dung), and there are few studies on the nutrient absorption characteristics of dragon fruit, and there are few studies on the need to use different nitrogen, phosphorus, and potassium fertilizers for dragon fruit fertilizers. Research Reports on Proportioned Administration

Because the nitrogen content of dragon fruit normal quality quality fruit is 0.80--1.20%, phosphorus content is 0.15--0.23%, potassium content is 1.41--1.78%, and the nitrogen content of its mature plant stem is 0.70--1.10%, The phosphorus content is 0.11--0.23%, while the potassium content can be as high as 2.41--2.75%. Therefore, the N:P:K application ratio during the whole growth period of dragon fruit is about 1:1:1.5. The organic fertilizer standard NY525-2012 on the Internet only indicates that the total amount of nitrogen, phosphorus and potassium is greater than or equal to 6%, and the organic matter is greater than or equal to 45% (note: in fact, organic fertilizers generally have total nitrogen, phosphorus and potassium ≥ 4%; organic matter content ≥ 25%), However, there is no clear requirement for the proportional relationship between the three. Due to the lack of knowledge of the law of dragon fruit fertilizer requirements, a large number of growers often blindly fertilize, causing unnecessary increase in production costs and affecting the output of dragon fruit. and quality

[0003] In addition, as we all know, urban domestic sludge is the sewage discharged from urban sewage treatment plants or large 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. These sludges cannot be directly used as fertilizers because they contain certain harmful substances and the water content is as high as 80-95%, but the sludges are also rich in nutrients such as nitrogen, phosphorus, and potassium. Mud is a very good raw material for organic fertilizer; in addition, as mentioned above, the organic fertilizer used by farmers is generally only the special organic fertilizer for dragon fruit made from decomposed chicken manure. This is because decomposed chicken manure is a kind of A relatively high-quality organic fertilizer, which is rich in pure nitrogen, phosphorus (P2O5), and potassium (K2O) (the organic matter of dry chicken manure reaches 65%, and the nitrogen, phosphorus, and potassium are about 6-8%). However, the preparation (composting ) The organic fertilizer mainly composed of decomposed chicken manure often causes serious environmental pollution (causes the breeding of mosquitoes and flies around the site, foul air, workers have long-term contact with some infectious bacteria, and the working environment deteriorates) and other problems
