Problems solved by technology

[0004] However, there are some problems in the current production, especially in the process of fertilization: (1) Excessive application of nitrogen and phosphorus fertilizers, ignoring potassium fertilizers, or the ratio of nitrogen, phosphorus and potassium does not meet the ratio of nutrients required by garlic
The patent document only emphasizes the amount of chemical fertilizers NPK and organic fertilizers, and the number of times of topdressing is not conducive to simplifying the labor force, and its fertilizer operation is not suitable for the planting mode of overwintering garlic in the north
CN101130464 (200710026078.0) discloses " formula and configuration method of garlic special fertilizer ", and this fertilizer is by potassium sulfate 25-30 parts, ammonium sulfate 19-21.5 parts, ammonium phosphate 35-38 parts, urea 5-6.5 parts, additive 3.5- 4 copies; the patent ignores the application of medium and trace elements, and its fertilization orientation of controlling nitrogen, phosphorus and potassium may only be suitable for local soil use in the Huaihe River Basin, and is not suitable for the typical long-season cultivation mode in Shandong garlic area

Abstract

The invention relates to a controlled-release fertilizer special for Shandong garlic and application thereof. The controlled-release fertilizer comprises the following raw materials: nitrogen fertilizer, phosphate fertilizer, potassic fertilizer, NAM additive, sulfur fertilizer, calcium magnesium phosphate fertilizer, zinc sulfate, ferrisulphas and borax. In the invention, the nutrient formula offertilizer specially for Shandong garlic is optimized on the basis of soil conditions in Shangdong; the use amount of nitrogen phosphorous is reduced and the use amount of potassium is increased, which meets fertilizer-needing regular pattern of the garlic; in addition, the addition of base fertilizer nitrogen is reduced to a certain degree. By using the controlled-release fertilizer, the yield of the garlic can be ensured, and the increasingly serious pollution caused by nitrate out of limits in underground water in rural areas can be prevented and controlled.

Description

Technical field: [0001] The invention relates to a method for preparing a special fertilizer for garlic, and belongs to the technical field of long-acting slow-release fertilizer and its application. Background technique: [0002] Garlic is rich in nutrition, high in economic value, resistant to storage and transportation, and can be supplied year-round. Since ancient times, garlic has not only been widely eaten, but also attracted the attention of the world with its important medicinal value. my country's "Compendium of Materia Medica" discusses that garlic has the effects of "relieving pain and swelling, disinfecting qi, removing wind and cold, invigorating the spleen and treating diarrhea". Garlic can resist a variety of harmful bacteria, especially the extracted allicin, which has a good bactericidal effect and is known as "natural spectrum antibiotics". Garlic contains the trace element selenium, which has a strong anti-cancer effect, so some people also call garlic "...
