Embodiment 1

[0019] The wet sludge discharged from the paper mill was mechanically dehydrated to obtain 105kg of semi-dry sludge with a water content of 50%, and 0.2kg of Bacillus licheniformis was added for composting and fermentation to obtain 75kg of sludge with a water content of 30%, and then added 5kg of urea with 47% nitrogen (N), containing potassium oxide (K 2 O) 5kg of 60% potassium chloride, containing phosphorus pentoxide (P 2 o 5 ) 15kg of 18% calcium magnesium phosphate fertilizer was mixed evenly, and then mixed with 0.3kg of Bacillus licheniformis with a content of 20 billion / g to prepare 100kg of compound microbial fertilizer.

[0020] Using this compound microbial fertilizer to carry out the fertilizer effect test on the 2-year-old fast-growing Eucalyptus, the results show that the DBH growth of the fast-growing Eucalyptus has a significant difference compared with the blank control, and its fertilizer efficiency has increased by 15.3%.

Embodiment 2

[0022] The wet sludge discharged from the paper mill was mechanically dehydrated to obtain 84kg of semi-dry sludge with a water content of 40%, and 0.15kg of Bacillus licheniformis was added for composting fermentation to obtain 60kg of sludge with a water content of 30%, and then added 20kg of ammonium sulfate containing 46% nitrogen (N), containing potassium oxide (K 2 O) 60% potassium chloride 10kg, containing phosphorus pentoxide (P 2 o 5 ) 10kg of 18% monoammonium phosphate was mixed evenly, and then mixed with 0.3kg of Bacillus licheniformis with a content of 20 billion / g to prepare 100kg of compound microbial fertilizer.

[0023] Using this compound microbial fertilizer to carry out the fertilizer effect test on the 2-year-old fast-growing Eucalyptus, the results showed that the DBH growth of the fast-growing Eucalyptus was significantly different from that of the blank control, and its fertilizer efficiency increased by 16.3%.

Embodiment 3

[0025] The wet sludge discharged from the paper mill was mechanically dehydrated to obtain 98kg of semi-dry sludge with a water content of 50%, and 0.18kg of Bacillus licheniformis was added for composting and fermentation to obtain 70kg of sludge with a water content of 30%. 10kg of ammonium chloride containing 46% nitrogen (N), containing potassium oxide (K 2 O) 60% potassium sulfate 10kg, containing phosphorus pentoxide (P 2 o 5 ) 10kg of 18% monoammonium phosphate was mixed evenly, and then mixed with 0.3kg of Bacillus licheniformis with a content of 20 billion / g to prepare 100kg of compound microbial fertilizer.

[0026] Using this compound microbial fertilizer to carry out the fertilizer effect test on the 2-year-old fast-growing Eucalyptus, the results show that the DBH growth of the fast-growing Eucalyptus has a significant difference compared with the blank control, and its fertilizer efficiency has increased by 15.8%.

Abstract

The invention relates to a compound microbial fertilizer prepared from papermaking sludge. The compound microbial fertilizer comprises the following raw material components in percentage by weight: 60-75 percent of papermaking sludge, 10-20 percent of a nitrogen fertilizer, 5-10 percent of a phosphate fertilizer, 10-20 percent of a potassium fertilizer and 2-5 percent of bacillus licheniformis. A method for preparing the compound microbial fertilizer comprises the following steps of: sampling field sludge, dehydrating, and adding bacillus licheniformis for performing aerobic compost fermentation; adding the nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and bacillus licheniformis; and mixing, pelletizing, drying, cooling, enveloping, packaging and warehousing. The compound microbial fertilizer has the positive effects: papermaking waste is utilized fully, so that resources are saved, the problem of waste treatment is solved, the environment is improved, waste is utilized comprehensively, and organic matters and nutritional elements needed by the growth are provided for the planting of trees such as eucalyptus spp and the like; and according to a raw material formula disclosed by the invention, the stability of organic matter components, active viable organism quantity and fertilizer elements in the fertilizer can be kept, the fertilizer utilization ratio is increased, and the growth of trees is facilitated.

Description

technical field [0001] The invention relates to a microbial fertilizer in the technical field of agricultural fertilizer preparation, in particular to a composite microbial fertilizer prepared from papermaking sludge. Background technique [0002] Microbial fertilizer is the development direction of the fertilizer industry in the future. In recent years, with the increasing production scale of my country's paper industry, paper companies have to deal with a large amount of paper sludge every day. The treatment of these papermaking sludge not only increases the cost of the enterprise, but also causes secondary pollution to the environment. At the same time, enterprises spend a lot of money every year to purchase chemical fertilizers to cultivate paper-making raw materials, such as fast-growing eucalyptus. Under such a background, a series of analyzes and experiments were carried out on paper-making sludge. Paper-making sludge contains 30% organic matter and a certain amount o...
