The key to the success of planting Pinellia ternata lies in the selection of land.

The drought of traditional Chinese medicine has become popular in the national traditional Chinese medicine market for many years, and its sales are not declining. But some people are not successful, one of the important reasons is that Pinellia ternata can not grow at all or grow poorly in some places. The loss outweighs the gain when planted in clayey or alkaline soil, planting 50kg bulbs and harvesting no more than 100kg. Poor growth or even no harvest in mountainous areas or areas with lack of water. In fact, dry Pinellia ternata is most afraid of drought and likes to be wet, like to grow in sandy or sandy soil, to have better water conservancy conditions. This variety is a semi-shade plant, and if this condition is not met, its yield will be greatly reduced.

How to carry out artificial shading? According to experience, the most important point is: when making the border, it is better to move from east to west, and the ridge is placed in the south, with a width of about 1.5 meters. On the ridge of the border, two rows of corn or sorghum were planted before and after the Valley Rain Festival, which grew up and took shape in June, just for shade. Corn and sorghum were accompanied by drought and Pinellia ternata for a lifetime. The planting method of Pinellia ternata is as simple as growing potatoes. Intercropping under mixed trees and fruit trees is also possible, but it must be left from the root of the main tree to prevent them from competing for water and fertilizer or diseases and insect pests. According to the actual situation, it is concluded that other intercropping methods are not ideal in the field operation, such as the requirements of weeding, ripening period, water and fertilizer conditions of Pinellia ternata are incompatible or contrary to the actual conditions.
