Description

A laboratory multi-layer planting device

technical field

The utility model relates to a laboratory planting device, in particular to a laboratory planting device capable of realizing multi-layer planting.

Background technique

In order to study the morphological characteristics of crop ontogeny, such as the morphological characteristics of seedlings, roots, stems, leaves, etc., it is generally necessary to cultivate seedlings in the laboratory, and the seedlings cultivated in the laboratory are often planted with planting devices. In the prior art, most laboratory planting devices mostly support the plant pots through the combination of several columns and support plates, and then plant the seedlings in the pots, and at the same time artificially spray the nutrient solution to the seedlings regularly to make them normal. grow. However, when planting seedlings with existing devices, the support plate is generally a single-layer structure, which takes up a lot of space. When artificially spraying nutrient solution, it needs to be realized with the help of spraying tools. Currently, the spraying or watering tools sold on the market are difficult. Control the watering speed, and people are worried that the seedlings will not absorb enough nutrients to affect the growth of the seedlings. They often spray too much nutrient solution, which can easily seep out from the seepage holes at the bottom of the cultivation pot and get wet. The supporting board or the ground is very unhygienic and will cause waste of nutrient solution. In addition, when the existing spraying tool sprays the nutrient solution, after the spraying tool is sprayed to a cultivation pot, it is necessary to remove the spraying tool from a When the pot is transferred to another pot, the water will also be sprinkled on the ground during the transfer process, which not only makes the ground wet and dirty, but also the waste of expensive nutrient solution cannot be ignored. In addition, manual spraying is labor intensive and inefficient.
