2. Seedling raising methods of dwarf berry seeds.

1. Land selection and preparation

The selection of mountain or woodland for sowing seedlings or hole sowing can make full use of the advantages of woodland organic matter content, fertility, buffering capacity to temperature and water and soil physical and chemical properties better than farmland soil. Deforestation cultivation should be carried out one year before sowing, and it is very beneficial to fully decompose organic matter and increase soil available nutrients, to improve soil physical and chemical properties, to coordinate the ratio of soil solid, liquid and gas, to eliminate disease sources and pests, and to promote growth.

2. Scaffolding climbing

Dwarf berry tree is a winding climbing vine. Camellia oleifera, citrus or small tree species with obvious slow growth are selected as climbing frame and are intercropped after pruning living climbing objects according to 3-meter row spacing. The artificial climbing bracket can be made of double-row cement columns or double-row wood, with a vertical row of columns every 4 to 6 meters.

3. Seedling land management

After the dwarf tree seedlings are unearthed, the cover grass should be removed in time, and weeds and seedlings should be removed in time. After the first true leaf is fully developed, the seedlings should be determined according to the plant spacing of 6 cm, topdressing for 1 to 2 times, and applying urea or compound fertilizer 300 kg / ha. Timely irrigation and drainage, drought watering, rain and waterlogging drainage. Diseases and insect pests in seedling stage are mainly caused by red body leafhopper, which should be controlled in time, otherwise it will lead to stem and rattan shortening.

4. Timely pruning

Dwarf tree pruning can significantly increase the diameter and volume of the previous mother stem and improve the yield and quality of Aristolochia manshuriensis in the same year. The field management work is carried out, such as setting up the first wire, tying it to the second wire and cutting off the small stems that are more than the second wire. In the middle of May, 2-3 new shoots were selected for each mother stem, and the shoot tips were removed when the 4th to 8th young leaves were removed, which was called 4-pruning or 2-pruning. It was trimmed once at an interval of about 5 days in mid-May and late May.
