Polygala tenuifolia prefers a cool climate, is tolerant of drought and averse to high temperatures. It mostly grows wild in relatively dry fields, roadsides, hillsides and other places. It is best cultivated in sunny, well-drained sandy soil. It can also be cultivated in clay loam and calcareous loam. Clay soil and low-lying wet areas are not suitable for planting. In production, seed propagation is the main method of reproduction, and either direct sowing or seedling transplanting can be used.

Sowing methods for Polygala tenuifolia

1. Sowing time: Spring sowing of Polygala tenuifolia is carried out in mid to late April, and autumn sowing in mid to late August, adapting to local conditions. It must not be too late, so as to ensure that the seedlings do not die because the temperature is too low after emergence. Generally, water the prepared land first, and sow after the water has seeped down.

2. Sowing method: Use 1-1.5 kg of seed per mu for Polygala tenuifolia. Before sowing, soak the seeds in water or a 0.3% potassium dihydrogen phosphate aqueous solution for 1 day and night. After removing them, mix them with 3-5 times their amount of fine sand. For autumn sowing, use seeds of the current year and sow in late August; they will emerge in the spring of the following year.

3. Seedling transplanting: Seedling transplanting of Polygala tenuifolia is carried out in early to mid March. Drill sow on the seedbed, cover with about 1 cm of soil, keep the seedbed moist, and the best temperature is controlled at 15-20°C. After sowing, seedlings emerge in about 10 days. When the seedlings are 5 cm tall, transplant them for final planting.

Planting methods for Polygala tenuifolia

1. Land selection and preparation: For planting Polygala tenuifolia, sunny, well-drained sandy soil is best. When plowing the land, apply sufficient base fertilizer at one time. You can use 40000 kg per hectare of barnyard manure or compost, break it up finely and spread it evenly. When plowing, 750 kg of superphosphate can be applied.

2. Thinning and filling in seedlings: When Polygala tenuifolia seedlings are 3-5 cm tall, thin them to a plant spacing of 3-6 cm. Fill in seedlings promptly where they are missing. For seedling transplanting, it is best to do it on rainy days or in the afternoon.

3. Loosening soil and weeding: Polygala tenuifolia plants are short, and seedlings grow slowly, so attention should be paid to loosening the soil and weeding, and weeds should be pulled out as soon as they appear. Loosen the soil shallowly, use a rake to lightly and evenly loosen the ground surface, do this 2 times in succession, keep the soil surface loose and moist, and avoid weeds covering the plants.

4. Watering and fertilizing: Apart from requiring an appropriate amount of watering during seed germination and the seedling stage, Polygala tenuifolia generally does not need frequent watering in the later growth stage. Apply topdressing once each in winter and spring every year and once between April and May. Per mu, 20-25 kg of cake fertilizer or 20 kg of superphosphate can be applied.

5. Foliar topdressing: For Polygala tenuifolia, from mid June to mid July each year, spray 50-60 kg per mu of 1% potassium sulfate or 80-100 kg of 0.3% potassium dihydrogen phosphate. Spray once every 10 days, for 2-3 consecutive sprays. The best spraying time is after 5 p.m.

6. Pest and disease control

① Root rot: Pull out and burn diseased plants promptly when found. In the early stage of the disease, spray 1000-fold 50% carbendazim solution 2-3 times every 6-7 days.

② Aphids: Spray with 1500-fold 40% omethoate solution, once every 6-7 days, for 2 consecutive sprays.

③ Leaf blight: Spray the leaves 1-2 times with 800-1000-fold mancozeb solution or 800-fold rimocidin solution.
