When will Polygonatum be planted?

Polygonatum polygonatum is generally planted in August or March, and Polygonatum polygonatum should be planted in areas with sufficient fertility, complete soil structure and good drainage and irrigation conditions, or in clayey or sandy soil, and artificial planting will be in semi-sunny areas. as long as there is sufficient sunlight, it is usually used for tuber transplanting or seed direct seeding, reasonable close planting and reasonable fertilization in the later stage, which is more beneficial to the growth of Polygonatum and increase the yield.

I. selection of land and land preparation

The main results are as follows: 1. When planting wild Huangjing like fertilizer and Xiyang, we should choose the area with complete soil structure, sufficient fertility and good drainage condition, which can be planted in clayey soil or sandy soil.

2. Although Huang Jing likes the light, artificial planting needs to choose to build shelter in the semi-sunny area or next to it, as long as there is enough sunlight, it can not be too strong, it will easily cause harm to Huang Jing.

3. When carrying out soil preparation, we first need to evenly spread a layer of base fertilizer on it, then turn it deeply to flatten the land, and then set up a good ditch all around. Finally, we can dig a small ditch every 1.5m in the field to sow seeds.

Second, sowing seeds

1. Sowing time: usually sowing around August or March every year.

2. Sowing methods: one is transplanting tubers, the other is seed direct seeding, and there are two sowing methods.

3. Tuber transplanting: dig out a part of the tuber from the soil around March, then divide it into segments, wait for it to dry, and put it evenly in rows after drying, then cover the soil to cover the seeds, and cover it with a layer of straw or plastic film at special times.

4. Seed direct seeding: sow the seeds directly according to the appropriate distance to cover the soil, and then deal with them in the same way as tuber sowing.

3. Reasonable density

1. Reasonable arrangement of planting density during sowing is beneficial to the better growth of Polygonatum polygonatum.

2. In general, about 800-1000 Polygonatum polygonatum can be planted per square meter, which can be planted according to the fertility of the soil.

3. In the areas with poor soil, it can be planted according to each row spacing 20cm and each plant spacing 10cm.

4. In the area with fertile soil, each row spacing 30cm and each plant spacing 20cm can be planted, which is beneficial to increase the yield of Polygonatum polygonatum.

IV. Rational fertilization

The main results are as follows: 1. Rhizoma Polygonatum needs a large amount of nutrients during the growth period, and the principle of frequently applying thin fertilizer can be followed when topdressing.

2. The first topdressing is about a week after Rhizoma Polygonatum planting, and its purpose is to raise seedlings, so a certain amount of nitrogen fertilizer can be applied.

3. In particular, Polygonatum polygonatum needs more nutrients in the peak season, and then it needs to be topdressing once a month, mainly applying farm manure, combined with appropriate amount of phosphate fertilizer and cake fertilizer, which can be combined with weeding, which is more helpful for Polygonatum to absorb nutrients.
