Indoor micro-nano bubble water culture device

Abstract

The invention belongs to the field of agricultural engineering cultivation equipment and particularly relates to an indoor micro-nano bubble water culture device. A cultivation cabinet is of a multilayered three-dimensional semi-closed structure, air vents are formed in the bottom of the cultivation cabinet, and a ventilation exhausting fan is combined, so that exchange of the indoor air and the air in the cultivation cabinet can be effectively carried out, and an inner environment of a house is sufficiently utilized; foldable doors can be closed when leaf vegetables are planted, and the foldable doors can be folded and put on cultivation grooves when bud vegetables are planted; a micro-nano bubble generator can generate micro-nano-grade bubbles through aeration, so that the oxygen dissolving amount in a nutrient solution is effectively increased; and meanwhile, the generated micro-nano-grade bubbles have special physical properties, and the quality of planted crops can be effectively improved. A micro-nano bubble technology is effectively combined with a controllable cultivation environment, and the indoor environment of the house is sufficiently utilized; and the planting quality can be improved, the management is simple, the energy consumption is reduced, and the device has a plurality of cultivation functions.

Description

technical field [0001] The invention belongs to the field of agricultural engineering cultivation equipment, in particular to an indoor micro-nano air bubble hydroponic device. Background technique [0002] With the rapid development of urbanization and economy, urban agriculture and home gardening have developed rapidly. People who have lived in cities for a long time are more and more yearning for rural life and returning to nature. At the same time, they also put forward higher requirements for food quality and safety. With the rapid development of agricultural technology in my country and the strong demand of urban residents for family farming, it is necessary to carry out research on the optimal design of indoor planting equipment for urban residents. [0003] At present, the demand for high-efficiency and safe facility vegetable cultivation technology is becoming more and more urgent. Micro-nano bubble water is a relatively new technology developed in Japan in recent...

Problems solved by technology

However, there is a problem of insufficient supply of plant roots in this cultivation method, which will lead to root death in severe cases.

[0005] At present, indoor hydroponic devices do not perfectly combine the micro-nano bubble oxygenation technology and intelligent vegetable cultivation equipment, and mostly use ordinary oxygenation technology, and ordinary large air bubbles cannot exist stably in the liquid, and will soon disappear. Therefore, it has no significant effect on the improvement of oxygenation effect and planting quality

In addition, micro-nano bubble technology is mostly used in field crops and large-scale facility planting. It is aimed at aerating irrigation water and increasing oxygen. No research on the aeration effect of nutrient solution has been found, nor has it been applied. To the home intelligent hydroponic device

At present, most intelligent cultivation equipment have a single cultivation mode and cannot provide multiple cultivation modes at the same time. At the same time, the management of household hydroponic nutrient solutions mostly adopts manual adjustment of EC value and pH value, which is extremely inconvenient to manage; The degree of modernization is already very high, and it can precisely control the growth environment of plants. In order to isolate it from the external environment, traditional materials with heat insulation are mostly used, and a variety of equipment is used to build a new growth environment. Suitable indoor environment, so the energy cost is relatively high
