Embodiment 1

[0086] Prepare the fermented compound fertilizer applicable to greenhouse vegetable cultivation according to the following steps

[0087] ①. Raw material measurement and mixing

[0088] Accurately measure 700 parts by weight of anaerobic sludge, 15 parts by weight of fly ash, 70 parts by weight of pulverized coal, 5 parts by weight of potassium chloride or potassium sulfate, and 11 parts by weight of urea from the alcohol aerobic fermentation device plate. Parts by weight, 55 parts by weight of phosphate rock powder and produced and sold by Beijing Jingpuyuan Bioengineering Co., Ltd., the trade name is AM-1 1.5 parts by weight, control C / N=20~30, pH=5.5~8, mix evenly, Prepare stacks;

[0089] ②. Intermittent stacking, aerobic fermentation

[0090] Stack the raw materials mixed in step ① intermittently, and carry out an aerobic fermentation in a natural environment. After the water content of the material drops to 40-45%, the first aerobic fermentation ends; prepare for the s...

Embodiment 2～ Embodiment 6

[0098] Prepare powdery fertilizer according to the method and step of embodiment, then according to the raw material formula in table and table 2, according to the following steps, prepare the nutrient-enhanced granular fermented compound fertilizer applicable to greenhouse vegetable planting of the present invention

[0099] ①. Granulation

[0100] Accurately measure 800-850 parts by weight of powdery fermented compound fertilizer, 25-30 parts by weight of ammonium sulfate, 50-75 parts by weight of phosphogypsum, and 50-75 parts by weight of granulation binder, and transport them to the drum after mixing, stirring and crushing Water steam spray granulation in the granulator;

[0101] ②.Drying, cooling, screening

[0102] After step ①, the granulated material is dried at a low temperature of 60°C-70°C (tail temperature) once, cooled once, sieved once, and then dried at a low temperature of 50°C-60°C (temperature at the tail end) twice. Secondary cooling and secondary screeni...

Abstract

The invention discloses a fermentation composite fertilizer suitable for greenhouse vegetable planting and a preparation method thereof, belonging to composite fertilizers, and particularly relating to an organic fertilizer with addition of bacterial cultures. The fermentation composite fertilizer is characterized by being prepared through aerobic fermentation of microbial inoculum by taking alcohol anaerobic tank mud as a main raw material; and the fermentation composite fertilizer comprises the following raw materials in weight fraction: 680-810 the alcohol anaerobic tank mud with water content of 50-55wt%, 10-15 coal ash, 60-70 coal dust, 50-60 phosphor gypsum, 3-5 potassium chloride or potassium sulfate, 9-11 urea, 45-55 ground phosphate roc, 1.5-2 streptomyces microflavus and 1.5-2 multi-element composite enzyme microbial inoculum. The invention provides the resource-saving and environment-friendliness type biological organic fertilizer which can be used for increasing vegetable quality, improving soil, supplying balanced fertilizer, controlling loss of inorganic fertilizer, protecting the environment, ensuring that vegetable products reach a green food standard and carbon-sourced substances and microbial bacteria in the organic fertilizer achieve the effects of physiological stimulation and metabolism reinforcement for crops. In addition, the organic fertilizer has complete nutrition.

Description

technical field [0001] The invention relates to a fermented compound fertilizer suitable for growing vegetables in greenhouses and a preparation method thereof. It belongs to compound fertilizers, especially organic fertilizers with the addition of bacterial cultures. Background technique [0002] Because the greenhouse vegetable planting industry can provide people with fresh vegetables every day throughout the year, it develops rapidly. According to statistics, 15% of the total supply of vegetables currently comes from the greenhouse vegetable planting industry. [0003] Like field crops, greenhouse vegetables are currently grown using fertilizers, and quick-acting chemical fertilizers are excessively applied, especially nitrogen fertilizers. This leads to problems such as single nutrient, low utilization rate, lack of organic components and medium and trace elements, and the quality of the produced fruits and vegetables decreases, and the taste deteriorates. Long-term u...
