Cold-resistant, like humidity, in the rainy season, vines are easy to get angry and take root. It can also grow rapidly in places with plenty of sunshine and water. Only in continental climate areas, plants planted in the south wall and the west wall are prone to scorching leaves in hot and dry seasons. Strong adaptability to soil.
In September, when the berries are ripe and purple-blue, they are immediately picked, washed, dried in the shade, disinfected with 0.05% carbendazim solution, drained and stored in wet sand. In the first ten days of March of the following year, the seeds were soaked in warm water at 45℃ for two days, and the water was changed twice a day. Then, the seeds were evenly mixed according to the ratio of 2: 1, placed in a sunny and cool place, covered with straw bags, sprayed with fine water frequently and kept moist. In about 20 days, when 20% of the seeds are exposed, you can sow.
Before sowing, the seedbed should be leveled and watered, and seeds and sand should be sown on the bed surface, and the sowing amount should be per square meter100g. The forest is covered with 1 cm thick loose humus soil, covered with a small arch shed and covered with polyethylene plastic film.
After the cotyledons of seedling management are unearthed, the film is uncovered at night in sunny days and covered all day in rainy days, so as to raise the soil temperature, promote the emergence of seedlings and prevent the harm of scarabs. In addition, water should be sprinkled frequently to keep the soil moist.
Transplanting: after spreading three leaves, choose cloudy days or after 3 pm and transplant at the density of 1× 1 ft. Water immediately after planting (1: 8). Never accumulate water for too long in rainy season. After two months, vines are generally more than 60 cm. At this time, the first coring can be carried out to prevent the vines from winding and shading, and promote the vine seedlings to be strong. Pick the heart once a month, combined with auxiliary support. By taking the above measures, the average thickness of vine seedlings can reach more than 0.5 cm during defoliation, and they can be planted out of the garden.
Parthenocissus tricuspidata is cold-resistant and drought-tolerant, and likes humid environment. The requirements for soil are not strict, and the climate adaptability is wide. Propagation methods mainly include cutting and layering, which can be carried out in spring, and the branches of old plants are bent and buried in the soil to take root. In the spring of the following year, it was cut from the mother and planted separately. Hardwood cutting is carried out in March and April, and the hardwood is cut into a section of 10- 15 cm and inserted into the soil, fully watered and kept moist. Softwood cuttings are taken from the new branches of that year and carried out in summer. Parthenocissus tricuspidata has strong vitality, so its reproduction is extremely easy to survive. After the seedlings survive and grow for one year, they can be transplanted and planted. When planting, we should dig deep into the soil and apply sufficient decomposed base fertilizer. When the seedlings grow to the length of 1 m, lead wires and ropes should be used to pull them onto the climber.
In the growing period, liquid fertilizer can be applied 2-3 times. And often mow the grass and loosen the soil to make a fence to avoid being submerged by the grass and promote its vigorous growth. Parthenocissus tricuspidata is afraid of waterlogging, so we should pay attention to prevent soil water accumulation.
Parthenocissus tricuspidata bears pruning. In the process of growth, branches and vines at doors and windows can be trimmed according to the situation to keep them clean, beautiful and convenient.
