Planting methods of Polygonatum odoratum

Polygonatum odoratum is a kind of herb of Liliaceae, which is widely distributed in China. It is also a kind of traditional Chinese medicine which has been used for a long time in our country, and the main part of the medicine is the rhizome, which has the effects of nourishing yin, moistening dryness, clearing heat and relieving cough. It has a good effect on reducing blood sugar, blood lipid and so on. So how to grow Polygonatum odoratum? The following editor brings you the planting method of Polygonatum odoratum, let's have a look!

1. Land selection and preparation

The wild area of Polygonatum odoratum is very large, so it has a strong ability to adapt to soil. However, artificial planting is mainly based on yield, so we still have to do a good job in soil selection before planting. The planting soil of Polygonatum odoratum should be thick, soft, normal drainage and irrigation and sufficient light, and the soil property is slightly sour sand. After selecting the soil, carry on the soil preparation work, turn the soil deep about 30cm. Then apply sufficient organic fertilizer per mu as the main base fertilizer, and the amount of organic fertilizer is controlled at about 3500kg. After fertilizing, fine rake flat and make high beds.

2. Seed stem selection

The propagation method of Polygonatum odoratum is generally based on the seed stem, so we should choose the underground rhizome as the seed stem before reproduction. The selection of seed stem should be judged according to the size and color of the rhizome. Generally, when harvesting in autumn, the fat, yellowish root buds of the same year are selected for rhizome reproduction. The reproduction of Polygonatum odoratum should follow the principle of digging and planting, if the weather is really not suitable for planting. Then the root buds should be stored in a cool indoor place to prevent deterioration and decay and reduce the germination rate. Finally, the amount of seed stem per mu was controlled at about 250kg.

3. Seed stem sprouting.

The seed stem needs to do a good job of sprouting before planting. First of all, you need to soak the seed stem in cold water for a day, and then remove it from the air-dried water. Put the seed stem in wet sand and put it in a container. The bottom of the container should be covered with about 4 cm of wet sand, and then 5 cm of wet sand should be spread on the top. The water content of the sand is controlled at about 15%, and then placed at a temperature of about 25 degrees. Check the change of temperature and humidity every three days and adjust the humidity properly. The situation of accelerating germination was checked in about 10 days. After a large number of seeds appeared in the seed embryo of the seed stem, the seeds were inverted three times a month at a temperature of about 5 degrees, and the seeds could be sown after one month.

4. Planting at the right time

Polygonatum odoratum is usually planted in October every year. Pay attention to the weather when planting, not on rainy days. Should be planted in cloudy or sunny days, in planting, the first to do a good job of trenching. Control the line spacing on the border surface, keep it at about 30 cm, and dig a ditch with a depth of about 15 cm. Then put the seeds neatly in the ditch and cover them with a layer of rotten farm manure, then cover the fine soil and water them to wait for germination.

The above is a brief introduction to the planting method of Polygonatum odoratum. The planting method of Polygonatum odoratum is actually relatively simple, but it is also necessary to strengthen management and increase yield. That's all for today's introduction.
