Organic-inorganic compound fertilizer special for wheat and preparation method thereof

Abstract

The invention discloses an organic-inorganic compound fertilizer special for wheat and a preparation method thereof, and belongs to the fields of agricultural resource recycling and environmental protection. The preparation method combines agricultural waste recycling and new fertilizer development; and chicken manure which is agricultural waste is subjected to conventional fermentation and added with certain inorganic fertilizer components according to the growth characteristics of the wheat and the nutrient requirement to prepare the special organic-inorganic compound fertilizer with rich nutrient, wherein the content of organic matters of the compound fertilizer can reach 25.90-27.75 percent and the total nutrient is 16.12 to 18.67 percent (including 7.80 to 8.39 percent of nitrogen, 4.57 to 5.38 percent of phosphorus pentoxide and 3.75 to 4.90 percent of potassium oxide). The fertilizer is special for wheat, is commonly applicable to regions for growing wheat and has the long-acting effect of an organic fertilizer and the fast effect of an inorganic fertilizer as well as obvious effect on the wheat growth and yield increase; meanwhile, the preparation method is simple, has low requirement on preparation machines, saves the cost and is favorable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the fields of agricultural waste recycling and fertilizer production, and in particular relates to a special organic-inorganic compound fertilizer for wheat, which uses chicken manure compost and inorganic fertilizers as components. Background technique [0002] Chicken manure is one of the most heavily polluted wastes in the agricultural livestock and poultry industry. Under the background of advocating a friendly environment around the world, how to deal with chicken manure is an important research topic. At present, a lot of chicken manure is piled up randomly without any treatment, which will undoubtedly cause huge pressure on the rural environment. In fact, using chicken manure in some indirect ways can have a series of positive effects. At present, most of the methods of using chicken manure are focused on making organic fertilizer, livestock feed or fish feed, but simply using the nutrient content in chicken manure to p...

Problems solved by technology

At present, most farmers still lack scientific guidance and management, especially when they are not sure about the period of fertilizer application, the type of fertilizer, and the amount of fertilizer, which leads to low yield and poor quality of rapeseed; especially with the increase of labor costs, many times The application of inorganic chemical fertilizers will undoubtedly increase production costs, cause soil compaction, and deteriorate soil quality

[0004] Patent No. 200610068595, the Chinese invention patent titled "A Special Fertilizer for Wheat" discloses a preparation method of a high-efficiency special fertilizer for wheat, which consists of a ratio of N:P 2 o 5 : K 2 O: Zn: Mn: Mo: B: Fe: rare earth nitrate: medical stone is 1: 1.1-1.2: 0.5-0.6: 0.01-0.02: 0.02-0.03: 0.01-0.02: 0.01-0.02: 0.01-0.02: 0.01 -0.02: 0.01-0.02 composition; although this invention belongs to special fertilizer for wheat, its specific formula is relatively complicated, requiring ten kinds of raw materials, and it is only composed of inorganic fertilizers, long-term application will cause production obstacles such as soil compaction

Patent No. 01128695.4, the Chinese invention patent called "a special fertilizer for wheat" discloses a specific nitrogen, phosphorus and potassium ratio of a special fertilizer for wheat, which is respectively 20: (10-12): (8-10), but only One-time application as base fertilizer cannot fully meet the nutrient requirements of wheat in each growth stage

In addition, the patent number is 200910078633.3, and the Chinese invention patent titled "Special Fertilizer for Wheat and Its Application" discloses a mass ratio of nitrogen, phosphorus, potassium, sulfur nutrients and zinc of 12-15:17-20: 10-15: 7-8: 0.5-1 special fertilizer for wheat, although this invention can realize the balance of nitrogen and sulfur nutrition in the matching fertilization method, its composition is still only a class of inorganic fertilizers, and it still cannot make the growth of wheat and production at a superior level

In addition, in addition to base application, the above-mentioned fertilizers often need to be topdressed, which greatly increases the production and management costs of crops, and it is also very troublesome to control the amount of fertilizer.
