Problems solved by technology

Direct application will lead to adverse effects in the following aspects: First, during the sugar production process, the potassium absorbed by sugarcane is often retained in the alcohol waste liquid after processing, and the sugarcane farmers will not pay attention to the supplement of potassium fertilizer during the application process. It often leads to potassium deficiency in sugarcane; second, the moisture content of fresh filter mud is more than 70%, and the dry matter content as a f

Embodiment 1

[0013] The production of 1 ton of urea accounts for 10%, calcium superphosphate or calcium magnesium phosphate fertilizer accounts for 55%, potassium chloride accounts for 10%, and dry filter mud accounts for 25.0%. Organic and inorganic compound fertilizers for sugarcane special use require 100kg of urea with a N content of 46%. ; containing P 2 o 5 550kg of calcium magnesium phosphate fertilizer with an amount of 16%; containing K 2 O content 60% potassium chloride 100kg, dry filter mud 250kg.

[0014] The preparation steps are as follows:

[0015] (1) The accumulated filter mud is naturally fermented for 30-40 days until the water content of the filter mud is 30%. The accumulated filter mud becomes decomposed and matured from top to bottom. Dry for 2-3 days until the water content is 20%, and use a pulverizer to crush the filter mud to 40-50 mesh (equivalent to 0.287-0.37 mm) for use;

[0016] (2) Nitrogen, phosphorus and potassium fertilizers are added to the fermented...

Abstract

The invention discloses a special organic/inorganic compound fertilizer for sugarcane produced by use of the filter mud from a sugar factory. The special organic/inorganic compound fertilizer is prepared from the following raw materials in percentage by weight: 4.17-42.87% of urea, 11.52-60.87% of calcium superphosphate or calcium magnesium phosphate, 3.33-16.66% of potassium chloride and 25.0-37.5% of dry filter mud. The special organic/inorganic compound fertilizer is prepared by the following steps of: (1) stacking the filter mud for natural fermentation; rotting the stacked filter mud for ripening from top to bottom; spreading the rotten filter mud; drying in the sunlight until the water content is 15-25%, and grinding the filter mud by a grinder; adding nitrogen, phosphorus and potash fertilizer into the filter mud after fermentation and grinding according to the proportion of the raw materials; mixing and then grinding, granulating, drying, cooling and screening; and packaging to obtain a finished product. The special organic/inorganic compound fertilizer disclosed by the invention has the advantages of long fertilizer efficiency, soil improvement, soil fertility improvement, avoidance of soil hardening and the like, can effectively improve the yield per unit by 0.5-1.0 ton of sugarcane and the sugar content of the sugarcane by 0.5-1.0%, and also can improve the utilization rate of the chemical fertilizer by 3-5%.

Description

technical field [0001] The invention relates to a special organic-inorganic compound fertilizer for sugarcane produced by utilizing filter mud of a sugar factory. Background technique [0002] Sugarcane is an important sugar crop in my country. It has a long growth cycle, requires a large amount of fertilizer, and needs comprehensive nutrients. For many years, sugarcane fields have only applied chemical fertilizers, but less organic fertilizers have been used. The organic fertilizers have not been replenished for many years, resulting in serious degradation of soil fertility in sugarcane fields, and the potential for increasing sugarcane production is getting smaller and smaller. Organic-inorganic compound fertilizer is a compound fertilizer that contains both organic matter and appropriate amount of chemical fertilizers. At present, the utilization rate of nitrogen fertilizer in our country is always about 30%. There are several ways to improve the utilization rate of chem...
