Latest High-Yield Polygonatum Planting Techniques and Methods Tutorial

Polygonatum is a medicinal herb with relatively high medicinal value, and it is very suitable for large-scale cultivation by the vast number of farmers. The environment it needs for growth is also relatively common, and the later management requirements are not high, so it is a good way out for the current rural areas. So how can the goal of high yield in Polygonatum be achieved? Let's learn about it together below.

1. Land selection and preparation

Polygonatum loves a relatively shady and moist environment, so when farmers choose a location, they can give priority to some hillside positions that do not face the sun. Carry out soil turning about 2 weeks before transplanting the seedlings, and grass roots and the like should be cleaned up thoroughly. One week after turning the soil, mix in organic fertilizer for soil enrichment, with the amount controlled at 3000-4000 jin per mu. When planting, the land should be leveled into strips about 1.5 m wide, with each strip spaced about 20 cm apart, to facilitate drainage and daily management.

2. Seedling and seed management

Polygonatum seeds take a relatively long time to awaken, so when awakening the seeds, a special nursery bed needs to be built for breeding. Prepare sandy soil with relatively good water permeability, then choose seeds, wet them with water, and place them about 10 cm into the sandy soil; they can be placed deeper to achieve a heat-preserving effect. The nursery bed should be watered regularly to keep it in a relatively moist state. After about 4-6 months, the seeds are basically awakened, and planting work can be prepared.

3. Field management

Once the seeds sprout, field management should begin. In the early stage, the main focus is on two aspects: fertilizer and water, and protection from strong light. Some base fertilizer needs to be prepared at the bottom of the seedlings. After planting the seedlings, watering should be controlled according to the degree of soil moisture at once a week, lasting about one month, and then measures for shading should be prepared. About one month after sprouting, start weeding, and later control it to once every 2-3 months. After the first weeding, start topdressing, and control it to once every one and a half months or two months according to growth conditions.

In the later stage of Polygonatum planting, what needs to be managed is actually not bad. At this time, farmers should focus on disease prevention. The first thing that is relatively likely to appear in its growing environment is root rot, which is mostly caused by excessive watering by farmers in daily care. Here the editor reminds farmers that everyone should still water according to the actual degree of soil moisture, and it is not necessary to water according to a fixed schedule. Its manifestation is that the plant tends to wither and the roots have black rot, and metalaxyl-hymexazol can be used for treatment. In addition, there is leaf spot disease, which causes abnormal leaves, and zineb wettable powder can be used for prevention and control. If it is a pest such as white grubs, trichlorfon can be used for prevention and control.

The above are techniques that can improve Polygonatum yield to a certain extent. Everyone can refer to the above planting conditions for cultivation, but should also combine them with their own actual planting situation. Our goal is for Polygonatum to achieve high yield.
