Introduction to Cuttage Propagation of Tripterygium wilfordii

Tripterygium wilfordii likes warm, humid and semi-shaded environment. It is native to tropical America and is a perennial evergreen herb. Powdery mildew vine can not only be used as an ornamental plant, but also can be made into a potted plant for ornamental use. It has a strong ability to adapt to light. If you want to propagate it artificially, you can use the method of cutting propagation.

Tripterygium wilfordii

Tripterygium wilfordii can be propagated by tender wood cuttings. The top tip or lateral branch of one-and-a-half-lignified cuttings was selected, and 2 or 3 leaves in the lower part of the cuttings were cut off to reduce water evaporation. The cutting substrate was mixed with the same amount of peat soil and sand. The substrate temperature was kept at 25-30 ℃ and rooting could take place in 10 days. The cuttage should be carried out in August. Cuttings cut can also be used to promote their rooting by blistering, and attention should be paid to keeping the water clean.

Cutting and Propagation techniques of Fujimoto Rose

Rattan rose is a rattan shrub of the subfamily Rosaceae, with tall plants. Every year, sturdy new branches are drawn from the base, and sturdy lateral branches grow at the apex of biennial rattan branches.

The propagation of rattan rose is mainly by cutting, but the cutting of fine varieties is difficult to survive, so it is more common to use grafting in production. Rootstocks are often used as rootstocks in Nanjing area. The root system of thorn-free rose is well developed, and it is best to use thornless rose as rootstock for grafting, branch, bud and root grafting. Branch grafting more than in late November, the rootstocks were dug out of indoor grafting (in the wet sand of the burying seedling bed, no watering within 10 days, but survived in 20 days) or grafted in early spring. Bud grafting can be carried out all the year round, often in the shape of a large door.

1. Cutting method of rattan in this season: softwood cutting is carried out in late spring or early autumn. If the spraying device is used, it is easier to survive, which can be carried out all the year round, but it is easiest to root when the ground temperature is 20.5 ℃, the air temperature is 10 ℃, and the relative humidity is 70% ~ 80%.

2. The grafting method of rattan rose: most of the rootstocks are seedlings, and the suitable period for grafting is from January to February. The main grafting methods are bud grafting and branch grafting.

3. Tissue culture of rattan rose: the 3rd ~ 7th segments of semi-lignified branches were selected, the leaves on the branches were removed, disinfected and cut into single-bud stem segments for culture.

The bare root seedlings should be planted in late autumn or early spring. Off-pot seedlings are planted in the growing season, but the rainy season is the best. Planting should choose places with good ventilation and drainage to the sun. After digging holes, re-apply base fertilizer; pour enough water after planting. See you later, dry watering. Avoid stagnant water in rainy season and pay attention to timely drainage. When it is hot and dry in summer, it should be watered in the evening.

During the growing period of new shoots, you should diligently chase 1:1:2 (or 3) ternary compound liquid fertilizer of nitrogen, phosphorus and potassium, and avoid concentrated fertilizer. 0.1%-0.3% urea and potassium dihydrogen phosphate combined with trace elements can also be used to spray foliar fertilizer in the morning and evening. Among them, the varieties with multiple flowering characters should leave 3-5 buds truncated in time after flowering, so as to promote the sprouting of new shoots and continue to bloom.

After several years of flowering, the old branches should be pruned and renewed by the method of "getting rid of the old and retaining the new". The pruning of vine varieties such as "rattan ink red" should be light, leaving 10-12 buds short for each branch. if there are too few buds, it is bound to affect flowering due to the over-vigorous growth of new branches.

In spring and autumn, aphids often harm tender shoots and leaves, and leaf-cutting bees bite leaves in the shape of round holes in the growing season, which can be controlled by spraying dimethoate and other drugs. The leaf surface is easy to suffer from black spot from June to August, and it is the heaviest when it is hot and rainy from July to August, which is easy to cause fallen leaves. The disease is mainly prevented by spraying Bordeaux solution or 200 times copper soap once a week for 3 weeks in spring.

During the onset of the disease, 800 / 1000 times of methyl topiramate or 400 times of thiophanate should be sprayed once a week, and the diseased leaves should be collected and burned. It is easy to suffer from powdery mildew in the rainy season, causing fallen leaves. 3-5 Baume sulfur mixture should be sprayed before sprouting. At the time of onset, spray 800 / 1000 times 50% Dyson zinc or equivalent Bordeaux solution once a week for 3 times in a row.

The seasonal flowers of this month are colorful, blooming all over the body and many flower heads, which is spectacular. In the garden, it is often attached to all kinds of well-ventilated shelves and corridors, which can form flower balls, styles, flower walls, flower seas, arches, corridors and other landscapes.

Cultivation and Management of Tripterygium wilfordii (Picture)

Plant name: Tripterygium wilfordii

Alias: rhombic leaf powder vine, false extract, self-leading cow (Chaoshan), night lead cow, Bubuqing (Puning), bone vine (Chaoyang), one-legged black kouch, Baifen (Guangzhou).

Latin name: Cissusdiscolor

Family name: grape family

Genus name: Tripterygium

Adaptive regions: native to tropical America, widely distributed in tropical to temperate regions of the world

Ecological classification: herbs > perennial evergreen herbaceous flowers

Ornamental classification: foliage

Height range: unknown

Morphological features: perennial vine herbs. There is a root in the ground. The stems and leaves are pink-green. The stem is round and fat is jointed; there is folded powder, which is longer than Zhang, and there are tendrils clinging to other things. Simple leaves alternate, long petiolate, leaf blade cordate, ca. 3 inches long, apex acuminate, base narrowly cordate, margin sparsely shallowly serrate, dorsal veins conspicuous, light green florets in summer and autumn, calyx truncate. The berries are fleshy with a seed.

Growth habits: its nature likes warm, humid and semi-overcast environment. There are about 200 species of plants of the same genus, and a few of them are cultivated as ornamental plants. In addition to powdered vines, there are also brocade leaf grapevines and so on.

Propagation and cultivation: Tripterygium wilfordii is used for cutting propagation. The annual semi-lignified tip or side branches are usually selected as cuttings in spring, summer and autumn. Cut 10 Mel 15 cm long, cut off half of the lower leaves and insert them into a mixture of vermiculite or peat soil and coarse sand at a temperature of 25 Mel 30 ℃. It can take root in about 10 days. You can also insert cuttings in water (pay attention to keeping the water clean) and plant in pots after rooting.

3 portions of garden soil and 2 portions of rotten leaf soil can be used as substrate, peat soil, rotten leaf soil plus 1 Zhe 4 river sandy soil and a small amount of base fertilizer can be used as substrate for pot cultivation. Old plants cultivated for many years can be combined with re-pruning to change pots before a large number of new buds grow in early spring. When changing pots, remove part of the old roots and old culture soil, and use new soil to plant again. Liquid fertilizer was applied every two weeks during the growing season. Summer watering should be dry and wet, it is best to spray to the leaves every day to facilitate growth; winter watering should be slightly sprayed to prevent leaf curls and red spiders; other seasons should also often keep the basin soil moist. The white powder vine is suitable for bright light environment and can also be adapted in darker places; avoid direct sunlight, such as strong light, there will be brown spots. Generally, it can grow at room temperature and can still be seen in the environment of 10 ℃ and 16 mol. But when the winter temperature is lower than 5 ℃, it is easy to catch cold, and the leaves turn yellow, lose luster, and even fall off. The disease of Tripterygium paniculata is common in powdery mildew, most of which are caused by excessive watering and poor ventilation, especially in the winter of production relations. Under home cultivation, the leaves are cleaned every 3 weeks to remove smoke and keep the leaves bright. The plant tends to grow fast and its branches are too long. It is often necessary to prune disorderly branches and guide them to stretch to maintain a good plant shape.

Landscape uses: small and medium-sized pot planting hanging cultivation, bright green leaves, tender buds covered with silver-white pilose, full of romantic free and easy sentiment, used to beautify the study, living room and bedroom, etc.; can also stand, make it grow around the support, very wild, quite resistant to viewing. Have a strong ability to adapt to light, can have bright scattered light indoor appreciation for many years, in the dark indoor can also be continuously arranged for 4 Mel 6 weeks or more.
