Embodiment 1

[0030] Such as figure 1 As shown, the tobacco hydroponic module of the present embodiment includes a hydroponic frame 1, a three-layer planting tank 2 arranged on the hydroponic frame 1, two spliced ​​planting boards 3 arranged on the planting tank 2 and a Each layer of planting groove 2 liquid inlet 5 and liquid outlet 6 connected nutrient solution barrels, the planting plate 2 is wider than the planting groove 1cm around, and covers the opening of the planting groove, and each planting plate is provided with 12 planting holes. Nutrient solution is housed in the planting tank 2, and the tobacco seedlings can be fixed on the planting hole 4 in an existing manner. The roots of the tobacco seedlings pass through the planting hole 4 to contact the nutrient solution, and one end of the nutrient solution barrel is connected to the liquid inlet of the uppermost planting tank. The other end is connected to the liquid outlet of the planting tank on the lowest layer, and a pump is pro...

Embodiment 2

[0045] The tobacco hydroponic method of the above-mentioned tobacco hydroponic module involved in the present embodiment comprises the following steps:

[0046] Step (1), take out the tobacco tissue culture seedlings from the culture bottle, wash and disinfect and transplant them on the planting board; then place the planting board on the surface of the planting tank, and at the same time inject sufficient nutrient solution into the planting tank in advance to control the nutrition The height of the liquid is about 3cm, and the temperature is 19±1°C, so that the roots of the tissue-cultured tobacco seedlings come into contact with the nutrient solution; adjust the concentration of the nutrient solution to keep it at a low level during the tobacco seedling stage, so that the electrical conductivity (EC value) is at 0.6mS / About cm; the nutrient solution circulates once every 20 minutes. The nutrient solution of this embodiment was changed every 7 days.

[0047] In step (2), th...

Abstract

The invention relates to a tobacco water planting module and a water planting method. The water planting module includes multiple water planting racks, multiple layers of planting grooves formed in the water planting racks, planting plates on the planting grooves and a nutrient liquid barrel communicated with liquid inlets and liquid outlets of the planting grooves in each layer; the periphery ofeach planting plate is wider than the corresponding planting groove, multiple planting holes are formed in each planting plate, each planting groove is filled with nutrient liquid, roots of tobacco seedlings penetrate through the planting holes to be in contact with the nutrient liquid, one end of the nutrient liquid barrel is communicated with the liquid inlet of the planting groove in the top layer of the water planting racks, and the other end of the nutrient liquid barrel is communicated with the liquid outlet of the planting groove in the lowest layer. A pump is arranged on a pipeline communicated with the liquid inlets of the planting grooves, and the liquid outlets and liquid inlets of every two adjacent planting grooves are communicated with each other; multiple LED lamps and microfans are arranged on the upper portions of the planting grooves in all layers; the tobacco water planting module also includes a monitoring device, and the monitoring device detects the temperature,humidity and carbon dioxide concentration of the water planting module in real time. The water planting module occupies a small floor space, is high in spatial utilization rate, capable of achieving cyclic utilization of water and circular liquid supply and small in water consumption, increases the survival rate of the tobacco seedlings and the growth ratio of plants, and ensures high quality andyield of tobacco.

Description

technical field [0001] The invention relates to a hydroponic module, in particular to a tobacco three-dimensional hydroponic module and a hydroponic method, belonging to the field of tobacco hydroponic. Background technique [0002] Hydroponics refers to a soilless cultivation method in which plant roots grow directly in a nutrient solution layer. This method cultivates plants to absorb nutrients directly from the solution, the plants grow faster, and the root system is sound and developed. At the same time, the root system is isolated from the soil, which can avoid various soil-borne diseases and does not require soil disinfection. At present, hydroponics is a commonly used method of plant cultivation in scientific experiments. It is widely used in the research of plant nutrition and plant physiology, especially in the study of the physiological functions of mineral elements and the application of chemical fertilizers. [0003] tobacco( Nicotiana tabacum ) is an annual h...
