Where are the producing areas of tsaoko? Introduction to the distribution of the main producing areas

The producing areas of tsaoko are mainly Yunnan, Guangxi, Guizhou and other provinces and regions. Tsaoko can also be called tsaoko kernel and tsaoko fruit, and it is a medicinal and edible Chinese medicinal material. It is generally cultivated or grows wild under sparse forest, at an altitude of 1100-1800 m.

Tsaoko cultivation techniques

1. Site selection: choose fertile valleys or stream sides, cut away excessive trees, control the shade density at 50%, clear weeds, and turn the soil and break up clods.

2. Planting: choose moist, fertile land with shade at the forest edge and beside ditches as the planting site. Deeply plow 20-27 cm, and after weathering for a period, dig holes about 13 cm wide and 7-10 cm deep at a plant spacing of 1.3-1.7 m, straighten the seedlings in the holes, cover with soil and press firm. Separate planting is mostly carried out around the Spring Equinox.

3. Weeding: carry out weeding from April to June and from October to December after harvesting the fruit, and avoid trampling the rhizomes and aboveground stems while weeding.

4. Earthing up: carry out earthing up before flowering to make the young buds grow strong; if the roots are found exposed, apply fertile soil so that the roots can absorb nutrients.

5. Drainage and irrigation: in the flowering season, if the rainfall is too heavy, it will cause flower rot; conversely, if it is too dry, the flowers tend to wither, causing reduced yield. Therefore, if drought occurs, irrigation should be carried out by diverting water where conditions permit. If there is too much rain, drainage work should be done well, weeds should be completely removed, and humidity should be reduced to lessen bud rot. In the flowering season, if there is one rainfall during May to July, it is beneficial for fruit setting and fruit retention, and the yield is also high.

6. Renewal pruning: tsaoko leaves must be renewed every year, and dead old plants should be cut away in time to facilitate the growth of new plants. During pruning, some overly dense branches and leaves can be properly harvested for use in essential oil production. The time for pruning and leaf harvesting is after the fruit harvest in October to November.
