Technical Field

[0001] The utility model relates to the technical field of seedling raising devices, in particular to a taro tissue culture micro-bulb germination and seedling raising device. Background Art

[0002] As a kind of root crop, taro has high nutritional value and unique flavor. It is very popular in the vegetable market. It also has a wide planting area and a long planting history in my country.

[0003] When cultivating taro seedlings, usually high-quality microbulb seedlings are selected for cultivation and experiments. The microbulbs need to be tissue cultured and germinated first. In the current taro seedling cultivation shed, the test tube method is mostly used to cultivate seedlings. The microbulbs are placed in tissue culture bottles or tissue culture tubes for cultivation. There are some functional deficiencies in the actual use process, and there is room for improvement. For example, whether it is a tissue culture tube or a tissue culture bottle, the opening is relatively small. After the microbulbs germinate and become seedlings, many fine roots will appear in the culture medium at the bottom of the test tube or bottle, making it difficult to remove the bulbs. The conventional solution is to pour it directly or clamp it with tweezers, which are more likely to cause damage to the young shoots and are not easy to push out the bulbs.
