Abstract

A tobacco plant hydroponic device, characterized in that it includes a non-transparent liquid storage tank and a planting plate buckled on the upper edge of the liquid storage tank, a water outlet is opened at the bottom of the liquid storage tank and a transparent plastic hose is connected. There is a tobacco seedling implantation hole in the center of the planting plate, and four support rods arranged in a cross are arranged around the tobacco seedling implantation hole. The height of the support rods is adjusted up and down by a fixed adjustment device fixed on the planting plate. A rubber band for supporting and fixing the stems of the tobacco seedlings is connected between the supporting rods, and a water inlet is provided on the side of the planting plate. When the device is in use, it is only necessary to put the hydroponic tobacco seedlings into the implantation holes, fix them with the rubber bands on the support rods, and add the prepared nutrient solution into the liquid reservoir, and the tobacco seedlings can grow normally. The device can not only effectively fix the tobacco plants and prevent them from lodging, but also can conveniently replace the nutrient solution and quantitatively add the nutrient solution.

Description

A hydroponic device for tobacco plants

technical field

The utility model belongs to the field of tobacco hydroponic technology, in particular to a tobacco plant hydroponic device suitable for scientific experiments.

Background technique

Hydroponics refers to a soilless cultivation method in which plant roots grow directly in a nutrient solution. Under hydroponic conditions, the plants absorb nutrients directly from the solution, the plants grow faster, and the root system is healthy and developed. Hydroponics is a commonly used method of plant cultivation in scientific experiments, and it is widely used in the research of plant nutrition and plant physiology.

Tobacco is an important economic crop and botanical model crop. Many research institutions and researchers regard tobacco as an important research object, and hydroponics is also a common cultivation method in tobacco research.

At present, people generally use foam board planting method (CN201020230551.4), iron wire or clip fixing method (CN200610041567.9 and CN200920289463.9) and vermiculite hydroponics method when carrying out hydroponics of tobacco seedlings. Although these methods can carry out the fixation and cultivation of tobacco seedlings, there are some problems. For example, the foam board colonization method is only applicable to seedlings. Inconvenient; iron wire or clip fixing method will cause damage to tobacco and affect its growth; vermiculite hydroponics method is cumbersome when sampling roots, and is easy to cause damage to roots.

Utility model content

Aiming at the deficiencies in the existing hydroponic technology, the technical problem to be solved by the utility model is to provide a simple and practical tobacco hydroponic device, which can not only effectively fix the tobacco plants and prevent them from lodging, but also facilitate Replace the nutrient solution and add the nutrient solution quantitatively.

The purpose of this utility model is achieved through the following technical solutions: a hydroponic device for tobacco plants, including a liquid storage tank and a planting plate buckled on the upper edge of the liquid storage tank, and a water outlet is opened at the bottom of the liquid storage tank and connected to a transparent There is a plastic hose with a tobacco seedling implantation hole in the center of the planting plate, and four support rods arranged in a cross are arranged around the tobacco seedling implantation hole. The height of the support rods is adjusted up and down by a fixed adjustment device fixed on the planting plate For adjustment, rubber bands for supporting and fixing the stems of tobacco seedlings are connected between the cross-corresponding support rods, and a funnel-shaped water inlet is provided at the side of the planting plate.

In the utility model, the fixed adjusting device is an adjusting nut. There is a scale line on the wall of the liquid storage tank to show the water level.

A section of soft material for preventing tobacco seedling stalks from being strangled is bonded to the middle part of the rubber band between the two supporting rods.

When the utility model is in use, it is only necessary to put the hydroponic tobacco seedlings into the implantation holes, fix them with the rubber bands on the support rods, and add the prepared nutrient solution into the liquid storage device, and the tobacco seedlings can be normal. grow. Moreover, the utility model device has increased a hose outlet and a funnel water inlet, and can also roughly estimate the volume of the nutrient solution in the liquid reservoir by checking the water level at the hose, which is very convenient to use.

In the figure: 1. liquid storage tank, 2. planting plate, 3. hose, 4. water inlet, 5. tobacco seedling implantation hole, 6. support rod, 7. nut, 8. rubber band, 9. soft Material, 10, water outlet.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figures 1 and 2, a tobacco plant hydroponic device includes a liquid storage tank 1 and a planting plate 2 buckled on the upper edge of the liquid storage tank. A water outlet 10 is opened at the bottom of the liquid storage tank and connected to a transparent plastic soft The pipe 3 has a tobacco seedling implantation hole 5 in the center of the planting plate, and four support rods 6 arranged in a cross are arranged around the tobacco seedling implantation hole. (Promptly the nut 7) is adjusted up and down, and a rubber band 8 for supporting and fixing the stem of the tobacco seedling is connected between the corresponding two support rods of the cross, and a funnel-shaped water inlet 4 is provided at the side of the planting plate.

When in use, the plastic hose 3 is lifted so that its highest point is above the planting plate 2, and then the nutrient solution is added through the water inlet 4 of the funnel. At this time, the height of adding the nutrient solution can be determined by checking the water level at the plastic hose. After the nutrient solution is added, insert the plastic hose 3 into the water inlet 4 of the funnel to fix it, and then adjust the support rod 6 to a suitable height through the nut 7 (the height should not exceed the height of the tobacco seedlings), and then press the Put two rubber bands 8 with soft materials 9 (i.e. sponges) on the connection of the rhizomes of the seedlings, then dip the root system of the tobacco seedlings in the nutrient solution through the implantation hole 5, and finally put the rubber bands on the corresponding During the growth of the tobacco seedlings, you can also adjust the elongation of the rubber band and the height of the support rod to maintain the fixing effect. The sponge is mainly used to wrap the tobacco seedlings to prevent the rubber bands from To damage it, when changing the nutrient solution in the liquid storage tank 1, you only need to take out the flexible pipe 3 from the water inlet of the funnel, and then drain the liquid, thereby avoiding the trouble of taking out the tobacco plant when changing the liquid. The device is easy to operate and is suitable for experiments on the whole growth period of tobacco. Shown in accompanying drawing 1,2 this device is only provided with four support rods 6 and two rubber bands 8, can also be provided with a plurality of, decides according to required condition.
