How to Grow Polygonum multiflorum Well? Detailed Planting Methods and Techniques
Polygonum multiflorum (He Shou Wu) is a medicinal herb with high medicinal and nutritional value. Currently, cultivating Polygonum multiflorum is one of the choices for many rural friends. So how do you grow it to get a higher yield? Qinnong Web will tell you here how to achieve high quality and high yield.
1. Seed Breeding
Many rural friends, when preparing Polygonum multiflorum seeds, choose to sun-dry them and then store them in order to dry them quickly. Actually, the best method is to sun-dry them until about half-dry and then air-dry them. This way, the seed survival rate will be much higher. Secondly, the best storage bag is a breathable, water-absorbent cloth bag, which helps preserve seed vitality. Only then will they grow fast and well when sown.
2. Soil Preparation
Polygonum multiflorum has high demands on soil fertility, so before sowing you must properly nourish the soil, and sandy soil is best. First, at the end of December, carry out the first soil cultivation, evenly spread farmyard manure, and let it absorb the fertility over time. Around early February, apply additional fertilizer, that is, the second application of farmyard manure. After this application is finished, begin turning the soil in early March to prepare for sowing. After two rounds of fertility supplementation, the soil fertility at this point will be extremely sufficient.
3. Fertilizing
Sow within 2-3 days after turning the soil, at a depth of about 2 cm. In the first few days before sowing, more water needs to be added: once a day before germination, once every 3 days after germination, and stop after one month. At about 2 months, it is about to enter the rapid growth period of the root tubers, and at this time some compound fertilizer needs to be applied to prevent insufficient nutrition, basically once every half month. Stop 1 month before harvest. When fertilizing, everyone must pay attention: if you find Polygonum multiflorum turning yellow, it means there is too much fertilizer.
4. Management
Field management is a very important matter. When there is too much water, drainage is needed. If Polygonum multiflorum is growing too densely in some places, transplant it in time to avoid poor nutrition in that area. Of course, weeding is also an unavoidable task. If your planting area is too dense, the editor recommends using stakes to free up more space so that each Polygonum multiflorum plant can enjoy a sufficient sunbath.
Polygonum multiflorum still has great economic prospects, and everyone must be careful when planting it. More planting insights are all on Qinnong Web. You can pay more attention to us. Selected planting tips are updated every day!
