Barren soil and heavy clay are not suitable for planting. On the selected forest land, weeds and shrubs should be cleaned up, and over-dense trees should be thinned down, the canopy closure should be adjusted to 50{bf}-60{bf}, and the soil turning depth should be 20-27 cm. The starting border is 1.2-1.5 meters wide and 20 cm high. Holes are dug in the border according to the row spacing. The hole size is 40 cm × 40 cm × 30 cm. Compost, stable manure and fired soil are used as base fertilizer in the hole and mixed with topsoil. 

2. Propagation method: seeds and ramets.

Seed propagation Seeds selection

Choose high-yield plants with large fruit, full seeds, and no pests and diseases as planting plants to plant Tsaoko.

Seed collection and seed treatment

When the peel of Tsaoko is purple-red, the seeds are silver-gray, and the sweet fruits are chewed, pick them, and then select the plump, fully mature, and disease-free fruits for seeding, which should be picked and planted. Peel off the peel before planting, wash the pulp, soak the seeds in clean water for 10-12 hours, and then use coarse sand and seeds in a bamboo pan to rub the arils. Or mix the seeds with 30{bf} plant ash, rub the seeds with your hands to remove the surface colloid layer, and then sow or dry and save until sowing in the next spring.

Sowing time.

Tsaoko can be harvested and sown at the same time, in spring and autumn. Autumn is better. Spring sowing should be carried out when the temperature rises above 18℃. The average temperature of the autumn sowing month is above 18-20℃. In one month, a large number of seeds will germinate and unearth. The germination rate can reach 80{bf} or more in 40-50 days after sowing. From December to February of the following year, the germination rate can reach over 90{bf}.

Sowing method

When sowing the Tsaoko, ditch the borders with a row spacing of 15-20 cm, and place the seeds at a plant spacing of about 6 cm. The seeding depth is 1.5-2 cm. After sowing, cover the soil and cover the grass with water. Seedlings can be planted after half a year.


Ramming reproduction

Before the sprouts start to germinate in the spring and before they are unearthed, select the annual sturdy ramets from the mother plants of Tsaoko, cut the lower leaves, and leave 2-3 upper leaves to reduce water evaporation. Dug up the budded rhizome, cut it to 7-10 cm, cut it off and plant it. Open the holes according to the plant row spacing of 1.3 meters × 1.7 meters, and the specifications of the holes are 50 cm × 50 cm × 40 cm, and each hole is planted with 1 cluster, covered with soil and compacted, and poured enough root water.

Field management

1. Shading: Reveal the Tsaoko immediately after emergence. If the canopy closure is not enough, set up a simple awning for shade.

2. Intertillage and weeding: from April to June each year after planting Tsaoko, intertillage and weeding are performed once each year. When weeding once after taking, the old and diseased plants that have died after the results are cut.

3. Top dressing: top dressing in the production areas where the conditions permit. In early spring, mix dried chicken manure with Tsaoko plant ash and sprinkle it around the plants. When the plant just blooms in summer, sprinkle plant ash on the leaves before the dew is dry in the morning to make extra-root topdressing. After harvesting the fruit in early winter, use manure and fire to burn the soil. At the root. It can also be combined with cultivating and weeding, and topdressing in a circular furrow.
