Embodiment 1

[0019] This embodiment is the special compound fertilizer for carbon-based moso bamboo:

[0020] According to the main material ratio of the original moso bamboo, it will account for 40% of the total after compounding nitrogen, phosphorus, potassium and medium and trace element fertilizers; 80 mesh carbon powder as filler will account for 60% of the total;

[0021] After mixing the main ingredients and filling materials evenly, use a granulation machine, and pack them into a bag of 50 kg after granulation.

[0022] The granulated carbon compound fertilizer was used in the cultivation of moso bamboo.

Embodiment 2

[0024] This embodiment is a special compound fertilizer for carbon-based eucalyptus:

[0025] According to the main material ratio of the original eucalyptus, it will account for 50% of the total after compounding nitrogen, phosphorus, potassium and medium and trace element fertilizers; taking 100 mesh carbon powder as a filling material will account for 50% of the total;

[0026] After mixing the main ingredients and filling materials evenly, use a granulation machine, and pack them into a bag of 50 kg after granulation.

[0027] The granulated carbon compound fertilizer was used in the cultivation of eucalyptus.

Embodiment 3

[0029] This embodiment is the special compound fertilizer for carbon-based fir trees:

[0030] Compound nitrogen, phosphorus, potassium and medium and trace element fertilizers according to the main material ratio of the original fir tree, accounting for 60% of the total; taking filler material 80 mesh carbon powder accounts for 40% of the total;

[0031] After mixing the main ingredients and filling materials evenly, use a granulation machine, and pack them into a bag of 50 kg after granulation.

Abstract

The invention discloses water-retention slow-releasing carbon-based compound fertilizer and belongs to fertilizer used in agriculture and forestry production. The carbon-based compound fertilizer is prepared from the ingredients of nitrogenous fertilizer serving as the major ingredient, phosphatic fertilizer, potash fertilizer and trace elements in the fertilizer and filling powdered carbon. The preparing method comprises the following steps of: mixing the ingredients uniformly to serve as powder material or pelletizing the powder material of the mixed powder and bagging for supplying the market. According to the invention, agriculture and forestry plant waste and the like are carbonized for preparing carbon powder, so that the utilization of waste materials can be achieved, the income of farmers can be increased, and the environment can be protected. Most importantly, filler such as mountain flour is replaced by the carbon powder so that the efficacy of the fertilizer can be improved, significant process can be made, and an unexpected effect can be achieved. According to the invention, the basic one-water double-fertilizer requirement in agricultural production can be met. As the carbon powder has strong permeability and a moisture-feed circulative-absorbing water-retention function, oxygen in the fertilizer can be slowly released, the use ratio of the fertilizer is improved, and essential condition for plant growth is met.

Description

technical field [0001] The invention relates to a fertilizer used in agriculture and forestry production, in particular to a water-retaining, slow-applied carbon-based compound fertilizer prepared by adding nitrogen, phosphorus, potassium and medium and trace elements to a carbon-based basis. Background technique [0002] The compound fertilizer used in the existing agricultural and forestry production is prepared by adding fillers such as stone powder, clay and the like to nitrogen, phosphorus, potassium and medium and trace elements. Since the filler is stone powder, clay, etc., it is only for filling and has no meaning, and it will accelerate the volatilization of nitrogen and potassium, as well as excessive use and long-term use, the increase of stone powder will be destructive to the soil. damage. [0003] The other is an organic-inorganic compound fertilizer. Except for nitrogen, phosphorus, potassium and medium and trace elements, the rest of the materials are organi...
