The key point of straw production of organic fertilizer

The straw production organic fertilizer production line adopts advanced composting fermentation process, inoculates high-speed and high-efficiency fermentation bacteria, which makes the straw cellulose rapidly decompose and transform, and all kinds of pathogenic bacteria, weed seeds and aphid eggs are killed, and the produce strong stability and full range of nutrient bio-organic fertilizers. We combine straw with biological manure and then use organic fertilizer production line equipment for processing. However, the bio-organic fertilizer produced contains a large number of elements such as nitrogen, phosphorus and potassium required for crop growth, and most of them exist in organic form, organic fertilizer. It can not only meet the needs of crop growth, but also improve the ability of crops to adapt to adverse environments.

Compared with chemical fertilizers, organic fertilizers are characterized by no fertilizer, no deficiency, stable supply, and long-acting effects. The straw is processed to not only make the straw waste harmlessly treated, but also increase the production and efficiency through the bio-organic fertilizer to realize the unification of ecological benefits and economic benefits.

The key points of straw processing organic fertilizer:
(1) Straw treatment. First, the crop straw crusher should be used to pulverize the material to a certain degree of fineness. Then, it is necessary to add an appropriate amount of raw materials such as poultry excrement or sludge to adjust the carbon-nitrogen ratio and moisture of the compost material, or to add strains and enzymes.
(2) Fermentation is divided into two stages: first, pre-fermentation, which can be carried out in open air or fermentation equipment, through equipment such as fermentation compost turning machine, forced air to supply oxygen to the accumulation layer or fermentation unit, and to add livestock to the main body of straw. In poultry manure, the main fermentation period of aerobic composting is about 3 to 10 days. The second is post-fermentation. After the semi-finished product of the main fermentation is sent to the post-fermentation process, the easily decomposable organic matter and the hardly decomposable organic matter which have not been decomposed in the main fermentation process are further decomposed to become stable organic substances such as humic acid and amino acid. For fully decomposed organic fertilizer products, the post-fermentation time is usually 20 to 30 days.
(3) Post-fermentation treatment. It can be further dried and pulverized as needed to turn the material into a qualified organic fertilizer raw material.
(4) Storage. Composting is generally used in spring and autumn. It must be stored in summer and winter. The storage method can be directly stored in the fermentation tank or in bags, requiring dry and breathable.

The above are the key points of attention for straw processing organic fertilizer, and this method is suitable for promotion in China's straw-rich grain production areas and areas with limited environmental capacity, especially suitable for urban and rural areas where environmental problems are more prominent.
