Polygonatum polygonatum is a perennial herbaceous plant with nodular rhizomes and enlarged parts with "turning" links. The dried rhizomes of Polygonatum polygonatum can be used as traditional Chinese medicine, which has the effects of nourishing yin and moistening the lungs, invigorating the spleen and invigorating qi, and benefiting the kidneys. Due to its large market demand, artificial cultivation of Polygonatum polygonatum has gradually emerged.
Polygonatum polygonatum has a long growth cycle and generally takes 3-4 years to harvest. In the first year of planting, Polygonatum polygonatum mainly grows rhizomes and leaves, and the aerial parts grow slowly. In the second year, the rhizomes and leaves continue to grow and begin to form multiple bud heads on the ground. In the third year, the bud head begins to swell and gradually forms a fleshy rhizome. By the fourth year, the rhizomes have become large enough to be harvested.
In the process of planting Polygonatum polygonatum polygonatum should be paid attention to:
1.Land selection and land preparation: Choose plots with deep soil layers and good drainage for planting. Before planting, deep tillage and foot fertilizer are applied.
2.Propagation method: Polygonatum polygonatum can be propagated by seed propagation and rhizome propagation. Seed propagation requires 2-3 years of growth before harvesting, while rhizome propagation can directly use the rhizome of Polygonatum polygonatum to propagate, and the growth cycle is relatively short.
3.Field management: During the growth of Polygonatum polygonatum polygonatum is required to be weeded, fertilized and watered in a timely manner. Weeding can prevent weeds from competing with Polygonatum for nutrients and water, fertilization can provide the nutrients needed by Polygonatum polygonatum and watering can maintain soil moisture and promote the growth of Polygonatum polygonatum
4.Pest control: Polygonatum polygonatum may be attacked by pests and diseases during the growth process. Common diseases include black spot and leaf spot, and common insect pests include grubs and ground tigers. When pests and diseases are found, it is necessary to take timely measures to prevent and control them, so as not to have adverse effects on the growth of Polygonatum polygonatum polygonatum.
5.Harvesting: When Polygonatum polygonatum grows large enough, it can be harvested. The rhizomes are dug up and cleaned at harvest time and then sun-dried or tumbled to dry. After drying, Polygonatum polygonatum can be used as a traditional Chinese medicine or used in the market for medicinal materials.
It should be noted that although the growth cycle of Polygonatum polygonatum is long, its ** is relatively high and the market demand is large. Therefore, the planting of Polygonatum polygonatum can obtain better economic benefits and market prospects.
