Problems solved by technology

Although the final product is also tasteless, pollution-free and has the characteristics of comprehensive nutrients and long-term effectiveness of organic fertilizers, but the composting cycle is long or the decomposition is not complete, and the treatment efficiency is low.
Moreover, in the practical application of flower cultivation, there is still a phenomenon of severe defertilization in a certain growth period, and the advantages of combining organic and inorganic fertilizers are not well utilized.

Embodiment 1

[0046] 1. Prepare primary fermentation products according to the following method: uniformly mix 300kg of cow dung, 300kg of chicken manure, 200kg of fly ash, 90kg of soy sauce residue, 60kg of crop straw, and 50kg of yeast waste liquid. According to the composting parameters, pH is 6, carbon and nitrogen The mass ratio of the compost mixture is 20:1, so that the moisture content of the final compost mixture reaches 65%; Enter the enzyme bacteria quick-rot agent; the compost temperature rises to 60 ° C, and after 48 hours, it starts to turn the compost. By stirring and forced ventilation, the oxygen content in the compost body is kept at 5%, and the temperature in the composting reactor is controlled at 60 °C. ℃, after 10 days to obtain a fermentation product;

Embodiment 2

[0051] 1. Prepare a primary fermentation product as follows: 700kg of cow dung is uniformly mixed with 70kg of phosphate rock powder, 80kg of alkali-making waste residue, 120kg of litter, 10kg of molasses, and 20kg of yeast waste liquid. According to the composting parameters, pH is 5.5, carbon The mass ratio of nitrogen is 25: 1, so that the moisture content of the final compost mixture reaches 40%; the final compost mixture is packed into the compost reactor, and the weight ratio of the enzyme bacteria quick-rot agent and the compost mixture is 1: 500. Insert the enzyme bacteria quick-rot agent; when the compost temperature rises to 65°C, keep it for 48 hours and then start turning the compost. By stirring and forced ventilation, the oxygen content in the compost body is kept at 15%, and the temperature in the composting reactor is controlled. At 55°C, a fermentation product was obtained after 6 days;

Embodiment 3

[0056] 1. Prepare a primary fermentation product as follows: combine 560kg of chicken manure with 50kg of phosphate rock powder, 80kg of alkali-making waste residue, 20kg of mineral potassium, 180kg of soy sauce residue, 20kg of litter, 50kg of humic acid, 20kg of distiller’s grains and 20kg of monosodium glutamate waste Mix the solution evenly, according to the compost parameters pH is 8.5, the mass ratio of carbon and nitrogen is 30:1, so that the moisture content of the final compost mixture reaches 60%; Add VT-1000 inoculum in a weight ratio of 1:10 to the compost mixture; when the compost temperature rises above 70°C and keeps for 48 hours, turn the compost. When the temperature exceeds 70°C, turn the compost immediately and stir and forced ventilation to keep the oxygen content in the heap at 8%, control the temperature in the composting reactor at 65°C, and obtain a fermentation product after 8 days;

Abstract

The invention discloses a flower organic-inorganic slow-release fertilizer as well as the preparation method thereof. The slow-release fertilizer contains the following materials by weight: primary fermentation products of 45 to 70 percent, chemical fertilizers of 2 to 35 percent, a conditioner of 5 to 30 percent, coating materials of 3 to 25 percent, an agglutinant of 1 to 10 percent, active materials of 0 to 15 percent and a sealant of 0 to 12 percent; the primary fermentation products, the chemical fertilizers and the conditioner are mixed for carrying out the secondary fermentation of composting, and then the products of the second fermentation are crushed for press molding; finally, compound fertilizer particles formed by the press molding are evenly sprayed with the coating materials and the agglutinant, thereby obtaining the flower organic-inorganic slow-release fertilizer; the flower organic-inorganic slow-release fertilizer of the invention has the advantages that the nutrition is rich, the composting process is fast, the rotten degree is good, the fertilizer is prone to be absorbed by flowers, the manufacturing process is simple, and the use is convenient.

Description

technical field [0001] The invention relates to a slow-release fertilizer and a preparation method thereof, in particular to an organic-inorganic slow-release fertilizer used for cultivating flowers and a preparation method thereof. Background technique [0002] Fertilization of flowers is a big problem. In addition to meeting the most basic needs of nitrogen, phosphorus, and potassium, it also needs a variety of trace elements. It is not easy to really master the fertilization of flowers. It is not as simple as "tube leaves, grow roots, and bear fruit". Although general livestock and poultry manure organic fertilizer is one of the most nutritious fertilizers and relatively safe for plants, it is extremely inconvenient and unhygienic to use, and is not suitable for household flower pots; secondly, bean cakes, vegetable cakes, and sesame cakes are also It is very suitable for ornamental flowers, but it must be fully retting, fermented and decomposed, diluted with water befor...
