In the soil preparation, combined with the application of fully mature farm manure, keeping about 3000 kilograms per mu. Turn the fertilizer into the soil, and then before planting, the soil will be shallow ploughed and raked, leveled to make the bed, waiting for planting.

2. Methods of reproduction

There are two propagation methods of Caoheche, such as fast stem propagation and seed propagation. Among them, because the production time of seed propagation is relatively long, so in production, it is mainly tuber propagation. The rapid stem propagation is generally carried out in autumn, and the underground tubers of the plant are dug out after October, and the contentment that is robust and free of diseases and insect pests is selected. Cut the tuber into about 3 centimeters, keep each tuber with a bud head, and the rest can be processed. Then on the prepared plot, the plant spacing will be controlled at about 22 cm, and the planting hole with a depth of about 7 cm is dug. Then put the bud head up, put a tuber in each hole, and then cover the right amount of fine soil and soil fertilizer.

For the seedlings born within three years, the height of the shade is kept at about 2 meters. On the other hand, the shade shed of seedlings for more than three years should be increased by about 50 cm. The shed should be covered with a shade net. The shade of about 80% should be maintained after the seedlings are transplanted in the same year, then it can be reduced by 10% in the second year, and finally in the fourth year, the shade of about 60% can be maintained.
