Description

Technical Field

[0001] The utility model relates to the technical field of nutrient agent adding devices, in particular to a nutrient agent adding device used for edible fungus culture material. Background Art

[0002] Edible fungi are favored by consumers for their high nutritional value and unique flavor. They have become the fourth largest industry in my country's agricultural economy, second only to grain, vegetables and fruits. Edible fungi are heterotrophic microorganisms that do not contain chlorophyll. Their growth and development depend on the degradation of biomass by mycelium to obtain nutrients. After the mycelium is expanded and propagated, it develops into mature fruiting bodies. Like other microorganisms, the rapid growth and reproduction of edible fungi require sufficient nutrition and energy. Therefore, the yield of edible fungi is closely related to the nutritional level of its culture medium.

[0003] Carbon and nitrogen are the two main macronutrients for fungi's structural and energy requirements; phosphorus, potassium and magnesium are also considered macronutrients for mushrooms. In addition, trace elements such as iron, selenium, zinc, manganese, copper and molybdenum are also necessary for a variety of functions. In the production of edible fungi, scientifically and rationally supplementing the various nutrients required for the growth of edible fungi is an effective way to improve yield and quality. Edible fungi nutritional supplementation is an agronomic process that involves the application of nutrients to the culture media used for edible fungi cultivation, which can promote the growth and development of edible fungi, increase yield and improve quality.

[0004] At present, small-scale edible fungi manufacturers still rely on manual addition of nutrients to the culture medium. Operators need to hold a container to add the nutrient solution to the stirring culture medium. On the one hand, the above-mentioned method of adding nutrients is time-consuming and labor-intensive, and it is easy to cause uneven addition, resulting in waste of nutrients, thereby increasing the cost of agricultural production; on the other hand, operators work under harsh working conditions, some nutrients are toxic, and long-term exposure to an environment containing high concentrations of nutrients will cause damage to human health. Therefore, the use of existing technology to add nutrients to edible fungi culture medium has technical problems such as low efficiency, large workload, poor uniformity, and harm to workers' health.

[0005] It should be particularly noted that the above technical information is only intended to deepen the understanding of the overall background technology of the present utility model, and should not be regarded as admitting or implying in any form that the above technical information constitutes the prior art already known to those skilled in the art. Utility Model Content
