Cultivation benefits of Polygonatum odoratum
1. Cultivation benefits are very high: usually Polygonatum odoratum is harvested 2-3 years after sowing. Generally, 300-500 kg of seed material is used per mu. The amount of seed material used is positively correlated with yield. The yield of one-year-old Polygonatum odoratum is 4 times the amount of seed material used, that is, a yield of 1200-2000 kg per mu. Two-year-old Polygonatum odoratum is 8-10 times the amount of seed material used, that is, a fresh yield of 4000-5000 kg per mu. Polygonatum odoratum is best dug up at two years old. Calculated at the 2010 market price of 8 per kg for fresh Polygonatum odoratum, the output value per mu is between 32000-40000 yuan. Compared with the output value of 1200 yuan per mu for growing rice, this is an increase of 30800-38800 yuan per mu, and the output value per unit area is about 30 times that of rice. In recent years, the price of Polygonatum odoratum has been rising every year, and the current price is already much higher than the 8 yuan of 2010. To put it another way, even if fresh Polygonatum odoratum falls below 4 yuan per kg, there will still be no loss. In the south, no medicinal herb variety can compare with Polygonatum odoratum.
2. Cultivation technology is simple: the sowing time for cultivated Polygonatum odoratum is from the middle of the 7th lunar month to the first ten days of the 12th lunar month.
