Polygonatum cultivation techniques and harvest years, how much does a seedling cost

Polygonatum is a Chinese medicinal herb, a fairly commonly used medicinal material, and the consumer demand is fairly large, so quite a lot of people grow Polygonatum. Do you want to grow Polygonatum? Then let's learn about Polygonatum cultivation methods together!

First we need to prepare the seedlings. The price of Polygonatum seedlings is generally around 10 yuan, and the price of high-quality Polygonatum seedlings is even higher. So we should select thick, healthy seedlings.

1. Site selection and preparation: Polygonatum likes a shady and moist growing environment, and the planting area is best on a hillside position that does not face the sun. Before transplanting the seedlings, the planting site should be tilled, the grass roots cleaned out thoroughly, and after tilling, the soil should be fertilized. Drainage ditches should be dug to facilitate drainage and daily management.

2. Seedling management: For the soil used for growing seeds, it is best to prepare sandy soil with good water permeability. Moisten the selected seeds and place them a bit deeper to achieve a heat-preserving effect. The nursery should be watered regularly, and after about 4-6 months the seeds can be transplanted, ready for the planting work.

3. Field management: Field management begins after the Polygonatum seeds sprout. In the early stage, pay attention to fertilizer and water and protection from strong light. Prepare some base fertilizer at the bottom of the seedlings. After planting the seedlings, control watering to once a week according to the degree of soil moisture, lasting about one month, and then take shading measures. About one month after sprouting, start weeding, and later control it to once every 2-3 months. After the first weeding, start topdressing, and according to the growth situation control it to once every one and a half months or two months.

4. Pest and disease prevention: The most common problem in Polygonatum is root rot, a disease caused by improper watering. Use metalaxyl and hymexazol to treat it. Another is leaf spot disease, which causes abnormal leaves, and can be prevented and controlled with mancozeb wettable powder. If the problem is white grubs, trichlorfon can be used for prevention and control.

Artificially cultivated Polygonatum generally has to grow for more than three years before it can be dug up, and digging in the fourth year is best. Now that you know the cultivation methods of Polygonatum, do you want to grow it?
