the Choerospondias axillaris (Choerospondias axilaris) seeds from the same mother strain are good for light, slightly resistant to yin, good for warm and humid climate and not cold-resistant, and are suitable for being planted in the south and southwest parts of the Yangtze river basin in China.

A culture container:

the traditional seedling raising container and the seedling raising container of the embodiment are respectively adopted to raise seedlings of the choerospondias axillaris seeds, wherein the traditional seedling raising container is commercially available, and the bottom porosity is less than 10%.

The cultivation method comprises the following steps:

the seeds are cultivated in the conventional seedling container and the seedling container of the embodiment respectively under the same environment of at the same time of by using the same culture medium, wherein the cultivation place of the conventional seedling container is selected from Yunnan Honghe which is very suitable for the growth of the choerospondias axillaries, and the whole process from the cultivation of the seeds to the seedling formation is completed in seedling containers, the cultivation place of the seedling container in the embodiment is selected from Beijing which is air-dried, and the cultivation process is referred to the seedling method in the embodiment two.

And (3) cultivating results:

the axillary choerospondias fruit seedlings grow huge lateral roots and multi-stage secondary lateral root roots in the seedling culture container of the embodiment , and the seedlings are easily taken out from the second container with the matrix without damaging the huge root system structure, the seedlings grow rapidly, the main stems are thick, the plants are high, and the transplanting survival rate is high;

the narrow main root and few lateral roots of the choerospondias axillaris seedling are grown in a traditional seedling culture container, the seedling grows slowly, the main stem is thin, the plant is short, and the transplanting survival rate is low.

In the object contrast, can obviously see out, use the container of growing seedlings of this embodiment to cultivate the seedling, owing to controlled seedling root system, the seedling growth is rapid, under the same condition of cultivation time, the seedling that traditional seedling culture ware was cultivated is all far exceeded to its plant height and trunk thickness. Although the cultivation environment of Beijing is far inferior to that of Yunnan Honghe, the cultivation result of the choerospondias axillaris seedlings is greatly improved by the seedling cultivation container and the seedling cultivation method in the embodiment, and the transplanting survival rate of the plants is far higher than that of common seedlings. Meanwhile, it is also explained that the seedling raising container and the seedling raising method of the present embodiment can achieve a very satisfactory cultivation effect without selecting a cultivation place according to seed habits.

The above embodiments are merely exemplary embodiments adopted to illustrate the principles of the present invention, but the present invention is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Such modifications and improvements are also considered to be within the scope of the invention.
