An indoor micro-nano bubble hydroponics device

Abstract

The invention belongs to the field of agricultural engineering cultivation equipment, in particular to an indoor micro-nano bubble hydroponic device. The cultivation cabinet of the invention is a multi-layer three-dimensional semi-closed structure, the ventilation holes opened at the bottom, combined with the ventilation and exhaust fans, can effectively exchange the air between the indoor and the cultivation cabinet, and make full use of the internal environment of the family; the folding door can be closed when planting leafy vegetables, When planting sprouts, it can be folded down and placed on the cultivation tank; the micro-nano bubble generator can generate micro-nano water bubbles through aeration, which can effectively increase the amount of dissolved oxygen in the nutrient solution. Special physical properties can effectively improve the quality of planted crops. The invention effectively combines the micro-nano bubble technology with a controllable cultivation environment, makes full use of the home indoor environment, can improve planting quality, is simple in management, saves energy consumption, and has various 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
