Planting techniques of Polygonatum polygonatum with high yield

Rhizoma Polygonatum is a kind of medicinal material with high medicinal value, which is very suitable for large-scale cultivation of farmers. The environment needed for its growth is also relatively common, and the later management requirements are not high, which is a good way out for the current rural areas. So how can Huang Jing achieve the goal of high yield? Let's learn it together.

1. Land selection and arrangement

Huang Jing likes a more shady and humid environment, so farmers can give priority to some non-sunny hillside locations when choosing places. The treatment of turning the soil should be carried out about 2 weeks before the seedling transplanting, and the grass roots and so on should be cleaned up, and the mixed organic fertilizer should be treated with fertilizer one week after turning the soil, and the dosage should be controlled at 3000-4000 jin per mu. When planting, the land should be leveled into strips with a width of about 1.5 meters, each with an interval of about 20 centimeters, which is convenient for drainage and daily management.

2. Seedling management

It takes a long time for Polygonatum seed to wake up, so a special nursery is needed for breeding. Prepare the sand with good permeability, then choose the seeds to be wet with water and put them into the sand about 10 cm, which can be a little deeper to achieve the effect of heat preservation. The nursery should be watered regularly to keep it in a relatively humid state. It is almost enough to wake up the seeds in 4-6 months or so, and you can prepare for planting.

3. Field management

When the seeds emerge, they will begin to manage in the field. At the initial stage, the main emphasis is on fertilizing water and preventing bright light. Some base fertilizer needs to be prepared at the bottom of the seedlings, and after planting the seedlings, watering should be controlled at once a week according to the degree of soil moisture, lasting for about a month, and then prepare for shade. Weeding began about a month after emergence, and weeding was controlled at 2-3 months in the later stage. Start topdressing after the first weeding, and top dressing once every one and a half months or two months according to the growth situation.

4. Prevention of diseases and insect pests

It is not wrong that Rhizoma Polygonatum needs to be managed in the later stage, at this time, the focus of farmers should be on disease prevention. The first thing that is relatively easy to appear in its growing environment is root rot, which is mostly caused by excessive watering by daily farmers. Here, the editor reminds farmers that watering should be based on the actual degree of soil wettability, not necessarily in accordance with the regulations. It shows that the plant has a tendency to wither and the root has black rot, which can be treated with metachlorin. In addition, it leads to abnormal leaf spot disease in leaves, which can be prevented and treated with Dysen zinc wettable powder. If it is a disease like grubs, trichlorfon can be used to control it.

The above is the technology to improve the yield of Polygonatum polygonatum to a certain extent, we can refer to the above planting conditions for planting, but also to collect their own planting actual situation for planting. Our goal is to ensure that Huang Jing can produce high yields.
