Culture methods of Polygonatum odoratum

1. Soil.

Polygonatum odoratum is suitable to grow in sandy soil with deep soil layer, good drainage and slightly acidic soil, and pay attention to changing the soil every other year when planting, so as to ensure the supply of nutrients for the growth of Polygonatum odoratum.

2. Seed sprouting.

Polygonatum odoratum seeds should be soaked in cold water for one day and one night before sowing, then the seeds with clean water should be cultured in a wooden box covered with 5 cm thick sand, and the fine sand layer should be kept moist during the culture. wait for the seeds to germinate and emerge.

3. Planting and breeding.

Polygonatum odoratum planting is generally carried out in October, it is best to choose cloudy days, watering the right amount after planting to ensure soil moisture, while paying attention to light absorption.

4. Temperature.

Polygonatum odoratum is planted until the seedlings grow, and the temperature begins to drop. At this time, measures should be taken to prevent the cold from overwintering, so as not to freeze the seedlings.

5. Fertilization.

Polygonatum odoratum likes fertile soil, so it should be fertilized on time and according to quantity when planting. And in the seedling growth period, but also to achieve timely topdressing. If the base fertilizer has been fully applied when planting, topdressing can reduce the quantity.

6. Pest control.

The main diseases of Polygonatum odoratum are leaf spot, root rot, gray spot and so on.

The main pest of Polygonatum odoratum is mackerel, and the control method is to irrigate the root and surrounding soil of Polygonatum odoratum with diluted solution to spray and kill pests.

Culture methods and matters needing attention of Polygonatum odoratum

The Culture method of Polygonatum odoratum and the requirement of soil

Cultivation of Polygonatum odoratum is best to choose deep soil layer and good drainage, sunny slightly acidic sandy soil, and then pay attention to the change of soil when planting and breeding, probably every other year to ensure the nutrients needed for growth.

Selection of seed stem

When breeding Polygonatum odoratum, the first choice is to propagate with the underground rhizome. After preparing the rhizome, pay attention to the maintenance of the root bud in the indoor leeward and cool place.

The acceleration of seed germination

Before accelerating seed germination, Polygonatum odoratum seeds should be soaked in cold water for 24 hours, and then removed to control clean water, then put the seeds into wooden boxes for culture, and then use wet sand to assist in about 5 cm, waiting for germination and growth.

Planting and breeding

Planting is generally in early October to late October, it is best to choose cloudy or sunny days to plant, so as to promote the growth and sprouting of new seedlings. During this period, pay attention to heat preservation, watering to ensure the moisture of the soil. Also need to give enough light.

Pay attention to overwintering and prevent cold in the culture of Polygonatum odoratum

Although Polygonatum odoratum is hardy, in winter, because the weather is too cold, we should pay attention to prevent cold, lest frostbite plants, can not grow.

Fertilizing and topdressing

Polygonatum odoratum likes fertile soil, so it is necessary to fertilize Polygonatum odoratum on time and amount to supplement sufficient nutrients, which is conducive to the growth of plants.

Not only fertilize, but also pay attention to topdressing, especially during the seedling period, but note that if you apply enough base fertilizer, you will no longer need topdressing so as not to burn the roots.

Pay attention to pest control

Polygonatum odoratum mainly has diseases such as leaf spot, root rot, gray spot and so on.

Pests are: grub pests, the control method is to use 90% crystal trichlorfon 1000-1500 times to irrigate the soil around the root until the pest is killed.

2. Morphological characteristics.

Rhizome finely Terete, subequal, 3-5 mm in diam., branched. The stem is 8-30 cm high. The lower part of the leaf is alternate or opposite, the upper part is more opposite, the top is often 3 whorls, oval to rectangular round, 2-6 cm long. Inflorescences with 2 (3)-flowered, pendulous, total pedicel 2-6 mm, pedicel (2) 5-6 mm long; perianth lavender, connate into tube-shaped full-length 6-8 mm, lobes 6, 1.5-2.5 mm long; stamens 6, filaments extremely short, inserted near middle of perianth tube; ovary ca. 1.5 mm, with style ca. as long as. Berries ca. 7 mm in diam., maroon. Produced in Sichuan (west) and Yunnan (northwest). Born under forests or on hillside grasslands. Polygonatum angustifolia P. cur-vistylum Hua is a dwarf species distributed in the same region, with many whorls of 3-6 leaves per whorl, striped lanceolate to strip-shaped, 3-7 cm long, 1-5 mm wide, drooping after anthesis, and the latter character is not found in other species of the same genus.

3. Growth habits

Most of the plants of this species are short, the rhizome is finely cylindrical, and the leaves are mostly alternate and opposite, oval to rectangular, which is easy to distinguish from other species in this system, but there are also a few transitional types between Polygonatum verticillata and Polygonatum verticillata.
