The breeding method of Rhizoma Polygoni

Zhonglou is the dry rhizome of Yunnan Zhonglou or seven-leaf flower of Liliaceae. It has the effects of clearing away heat and detoxification, relieving pain and relieving pain, cooling the liver and calming the liver, and has a high planting prospect. There are generally two methods of seed reproduction and rhizome reproduction. Let's take a look at the breeding methods of Zhonglou.

The growth habits of heavy buildings

Chong Lou was born under the forest on the hillside and in the shady place of the thicket. It was born under the forest at an altitude of 1800-3200 m. It likes temperature, humidity and shade, but it is also cold, drought-resistant, and afraid of frost and sunshine. The average annual temperature is 13-18 ℃. Sand and loam with high contents of organic matter and humus are planted, especially in riverside, Yanbian and Bei Yinshan.

Rhizome propagation of Rhizoma thunbergii

The cultivation of heavy buildings is mainly based on rhizome propagation, which is easy to use, the survival rate is very high, and the survival rate is more than 90%. It can be planted all the year round, cut into small segments with intact rhizomes with bud heads (which can bloom and seed in the same year) or bud remnants with germinating ability, dry properly and mix plant ash after cutting, sow in trenches according to 10-30 cm plant spacing x 30-50 cm row spacing, and cover the soil no more than 3-5 cm. Skin can cover plant withered leaves or thin film, can play the role of moisturizing and bud protection, every year from March to June is the seedling stage of the heavy building.

Seed propagation of Rhizoma thunbergii

The seeds of Zhonglou have obvious post-ripening effect, and the embryos need to be dormant before they can germinate. Under natural conditions, the seedlings can only be unearthed after two winters, and the emergence rate is low. Most of the seeds mature from September to December and are now collected and sown. A small number of seedlings emerged in August of the second year, and most of the seedlings could not grow until May of the third year. The seedlings propagated from the seeds grow slowly and the emergence rate is very low. After 3 years, the seedlings of Dianzhonglou can only be transplanted when they form obvious rhizomes, and the seeds can be harvested for 5-8 years.
