The method of keeping the platycodon should pay attention to the following points:
The flowering period of platycodon grandiflorum is long, and the fruit ripening period is very inconsistent. When planting, the two-year-old plants should be selected, and the topping of the plant seedlings should be topped to increase the seed number and seed fullness of the fruit, and improve the seed yield and quality. In the middle and upper part of September, the weak side branches and the inferior inflorescences were cut out to concentrate the nutrition on the upper middle fruit. When the hazelnut turned yellow and the top of the fruit was cracked in October, it was harvested in batches. Because the mature seeds of the platycodon are prone to cracking and causing the seeds to scatter, they should be harvested in time. When harvesting, the fruit stalks and branches should be cut together. The indoor ventilated place should be cooked for 3 to 4 days, then dried and threshed, and the sorghum seeds and impurities are removed and stored for later use. Linyi Fertilizer Network Copyright
