Abstract

The invention discloses a special compound fertilizer suitable for southern rice and a preparation method thereof. The compound fertilizer is prepared from the following raw materials: 20-30% of a nitrogen bacteria fertilizer, 10-20% of a phosphorus bacteria fertilizer, 10-15% of silkworm excrement, 10-15% of pig manure, 10-15% of plant ash, 10-15% of urea, 1-2% of potassium sulfate, 1-2% of calcium superphosphate, 1-2% of calcium magnesium phosphate, 1-2% of ammonium chloride, and 1-2% of potassium chloride. According to the special compound fertilizer suitable for southern rice and the preparation method thereof, the corresponding special compound fertilizer for southern rice is prepared on the basis of the advantages of southern livestock breeding and silkworm breeding, the fertilization effect is excellent, and the compound fertilizer is made into chemical fertilizer dry granules and convenient to apply.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a compound fertilizer suitable for southern rice and a preparation method thereof. Background technique [0002] Rice is a kind of herbaceous Oryza genus, which belongs to cereals. It is also the most important and longest food in Oryza genus. At present, rice is one of the main grains. Fertilization, for example, by throwing urea or poultry manure on the fields, but the fertilizer is less effective due to its relatively simple composition. Contents of the invention [0003] The main purpose of the present invention is to provide a special compound fertilizer suitable for southern rice and its preparation method, which can effectively solve the problems in the background technology. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] A special compound fertilizer suitable for southern rice, the compound fertiliz...
