Polygala polygala is a kind of medicinal material, and its revenue and profit per mu are closely related to the market price and output. The planting technology of polygala root is as follows:

Polygala prefers a cool climate and is resistant to drought and drought. Avoid high temperatures and tend to grow wild in drier fields, roadsides, hillsides and other places. It is better to cultivate in sunny, well-drained sandy soil, followed by clay loam and calcareous loam. Clay and low-humidity areas are not suitable for cultivation. Choose an area with high, dry terrain and good drainage. It can be planted on general land. Remove and apply basal fertilizer before soil preparation. Because Polygala is a perennial herb, sufficient basal fertilizer must be applied.

37,500 kilograms of circle fertilizer or compost per hectare and 750 kilograms of superphosphate are commonly used for plowing and leveling. In the north, drill sowing is mostly used on flat land. Propagation by seeds can be done by direct seeding or seedling transplanting. Since the polygala capsules crack when mature, the seeds are easy to scatter on the ground, so the seeds should be harvested when the fruits mature in July to August. Spring sowing is carried out in mid-to-late April, and autumn sowing is carried out in mid-to-late October or early November.

Cultivation techniques

On the prepared ground, spread the seeds evenly into the ditch, cover with 1 to 2 cm of soil, and sow in shallow ditches with a row spacing of 20 to 23 cm. Sow seeds per hectare. The amount is 11.25 to 15 kilograms. After sowing, lightly suppress and water enough. Seedlings will begin to emerge about half a month after sowing. Seedlings will emerge in the spring of the following year after sowing in autumn. In early or mid-March, drill seeds are sown on the seedbed and covered with 1 cm of soil after sowing.

To keep the seedbed moist, the appropriate seedbed temperature is 15 to 20°C. Seedlings will emerge about 10 days after sowing. The seedlings are about 6 cm tall and can be planted. Planting should be done on rainy days or in the afternoon, with a row-to-plant spacing of 20 to 23 cm x 3 to 6 cm. Polygala plants are short and small, so weeding needs to be done frequently during the growth period to prevent weeds from covering up the plants. Because it likes dryness, except for proper watering during the seed germination and seedling stages, it is not advisable to water frequently during the later stages of growth.
