[0006] 2. In the process of microorganisms fermenting organic substances, C / N will be destroyed in some stages, resulting in the loss of nitrogen elements. The ammonia gas volatilized in this process will cause air ammonia pollution (heavy smell, damage to human body), resulting in loss of nitrogen fertility

Embodiment
[0073] In this embodiment, a preparation method of an organic fertilizer formula: prepare 1 ton of tree branch leaves, 4kg of urea, 75kg of ordinary dry flour, starch, water, gelatinized starch mixed with 1:3 / 4 urea and starch urea;
[0074] Crush: Crush 1 ton of tree branches and leaves until the maximum diameter is less than 1cm;
[0075] Mixing: Mix 75kg of starch with some water and mix thoroughly with 1 ton of tree branches and leaves after gelatinization, and pile up the stirred mixture to form a heap;
[0076] The mixed and stirred tree branches and leaf piles are placed in the natural environment for fermentation. The fermentation period is 60 days. During the fermentation process, the placed push bodies are regularly turned over; , Sixth, eighth, tenth, fourteenth, eighteenth, twenty-second, twenty-eighth, thirty-second, fortieth, fiftieth day piles of branches and leaves , and carry out sampling monitoring on the internal temperature of the pile body, record once e...

The invention belongs to the technical field of agricultural fertilizers, and particularly relates to an organic fertilizer formula, a preparation method and a control method thereof. 1 ton of tree branches and leaves, 4-4.4kg of urea, 75-100kg of common dry flour and starch, water, and gelatinized starch urea obtained by mixing and gelatinizing urea and starch in a ratio of 1:3 / 4 are prepared. According to the invention, the gelatinized starch urea is utilized to form a coating layer on urea for sustained release of urea, so that the nitrogen element in the whole fermentation process is relatively stable, the utilization rate of materials is improved, the composting time is shortened, nitrogen loss is reduced, air ammonia pollution caused by volatilized ammonia gas is avoided; meanwhile,the fermentation process of the organic fertilizer is monitored in real time to establish a mathematical model, so that precise control over the fermentation process is achieved, the amount of gelatinized starch urea capable of being added and the ratio of gelatinized starch to urea are determined, the conversion efficiency of organic fertilizer is effectively improved, the utilization rate of materials is increased, and the composting time is effectively shortened through mathematical model control.
Description
technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an organic fertilizer formula, a preparation method and a control method thereof. Background technique [0002] Organic fertilizers: Carbon-containing materials mainly derived from plants and (or) animals and applied to the soil to provide plant nutrition as their main function. It is processed from biomass, animal and plant waste, and plant residues, eliminating toxic and harmful substances, and rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for gree...
