How to plant Rhizoma Polygonatum with higher yield and better benefit

Land preparation: choose clayey soil or sandy soil. Sowing method: tuber transplanting and seed direct seeding. Reasonable density: barren plots can be planted at a distance of 20cm per row and 10cm per plant, while fertile plots can be planted at a distance of 30cm per row and 20cm per plant. Scientific fertilization: in the peak growing season of Polygonatum polygonatum, farm manure is mainly applied, and then supplemented with a small amount of phosphate fertilizer and cake fertilizer.

I. selection of land and land preparation

1. The living habits of wild Polygonatum polygonatum are usually sun-loving and fertilizer-loving, so when planting, it can be selected in areas with relatively complete soil structure, sufficient fertility and good drainage system, which can be clayey soil or sandy soil.

2. Although the wild Huang Jing likes the light, when carrying out artificial planting, he should also choose the semi-sunny area, or build his own shelter.

3. When preparing the land, we should first spread a layer of bottom fertilizer evenly on it, then turn it deeply, then flatten the land, and finally set up a ditch around it, and a small ditch every 1.5 meters in the field to wait for sowing.

2. Sowing methods

The main results are as follows: 1. The seeds are usually sown in August or around March, and the sowing methods are tuber transplanting and seed direct seeding.

2. The tuber transplanting is around March, when the tuber is dug out from the ground, then divided into small sections, dried and placed evenly in 1 row, then covered with thin soil and covered with a layer of straw or plastic film if necessary.

3. The direct seeding of seeds is even more simple. The seeds can be sowed and covered with soil directly according to a reasonable distance, and the later treatment is the same as that of tubers.

3. Reasonable density

1. In order to make Polygonatum grow better, it is necessary to arrange the planting density reasonably when sowing. Generally, Polygonatum polygonatum can be planted about 800-1000 plants per square meter, which can be planted according to the fertility of the soil.

2. In places where the soil is relatively barren, it can be planted according to the distance of 20cm per row and 10cm per plant.

3. In the more fertile plots, it is planted according to the distance of 30cm per row and 20cm per plant, so that the yield of Polygonatum polygonatum will be higher.

IV. Scientific fertilization

The main results are as follows: 1. Polygonatum needs more nutrients in the process of growth, so when topdressing, it is necessary to topdressing according to the principle of frequently applying thin fertilizer. The first topdressing is about 7 days after Polygonatum planting, which is mainly for raising seedlings and applying more nitrogen fertilizer.

2. Rhizoma Polygonatum needs more nutrients in the peak season, so it needs to be fertilized once a month, mainly farm manure, then supplemented with a small amount of phosphate fertilizer and cake fertilizer, each fertilization can be combined with weeding, which is beneficial to the nutrient absorption of Polygonatum.
