How do the tender branches of the vine be cut and planted this month? Softwood cuttage technique of rattan this month

Fujimoto rose can also be called vine rose, climbing rose, like the warm leeward, air circulation environment. It grows well when planted in a fertile, loose and well-drained place. Because of its colorful flowers, many flower heads and long flowering period, it has high ornamental value, can be used as scaffolding and balcony greening materials, and plays a unique role in landscaping and beautifying the environment. So today the editor is going to talk about the tender wood cuttage technique of rattan this month.

1 making bed and covering sand

Select the flat land and make a high bed with a height of 0.1m, a width of 1.2m and a length of 10-20cm. The sermon is wide 40cm, turn the bed soil 10cm deep, hold flat. After that, spread fine river sand on the bed with a thickness of 10cm, and pat the edges around the bed. Soil disinfection with 0.5% potassium permanganate 24 hours before cutting can prevent cuttings from infection with germs.

2 cutting cuttings and cuttings

In late June, on cloudy and rainy days or in the morning and evening, the semi-lignified branches were selected from young and perennial trees with strong growth (0.35-0.5cm thick). Each cuttings have 2-3 full buds, the upper cut is 1-1.5cm away from the upper buds, and the cut under the cuttings is under the leaves or axillary buds, which is beneficial to rooting. At the same time, the upper 2 compound leaves should be retained, each compound leaf should have 2-3 leaflets, and there should be obvious axillary buds in the axils of the leaves.

3 cuttage treatment and cuttage

The cut cuttings should be soaked in clean water immediately to prevent the cuttings from wilting. The cuttings were cut and bundled into a bundle of 50 or 100, then quickly dipped in naphthalene acetic acid 800-1000mg/L, and the 3cm at the base of the cuttings was soaked in solution for 10 minutes. When cutting, the plant spacing is 5-6cm, the row spacing is 8-10cm, and the cutting depth is half of the cutting depth. Cuttings should be uniform and tidy, cuttings leaves do not overlap each other, and after cutting, the soil should be compacted and watered by hand. The cutting time in the open field began in mid-late June and lasted until the beginning of September.

4 cover net

After the cuttings are watered thoroughly, bamboo strips are cut into an arch frame every 1m on both sides of the seedbed, arch height 0.5cm, upward build a double-layer sunshade net with a transmittance of 20-30%, and the two ends are pressed firmly with bricks.

5 spraying water and removing the net

After covering the net, spray water every 1-2 hours from 8am to 4pm on a sunny day. High temperature weather, it is necessary to appropriately increase the number of water spraying at noon, cloudy days can reduce the number of water spraying. The amount of water sprayed each time can be received by the blade. When the cuttings have 5-8cm long roots in 4-6 days, the shading net can be removed in the evening or in cloudy and rainy days, and then water can be sprayed every 5 days. From September to October, as long as the bed substrate is not too dry, there is no need to spray water.

6 Seedling stage management

6.1 topdressing

After cutting for about 60 days, diammonium phosphate or compound fertilizer was sprayed evenly on the seedling bed with a dosage of 18-20kg per mu. Water should be sprayed in time after fertilization, of course, foliar fertilizer 80mg/L urea + 120mg/L potassium dihydrogen phosphate could also be sprayed.

6.2 Disease and pest control

5-7 days after cutting, 500 times carbendazim was sprayed for disinfection after stopping water at night, and then sprayed every 7 days for 3 times in a row.

6.3 overwintering protection

Fujimoto rose has a certain degree of cold resistance, which can withstand the lowest temperature of minus 15 degrees Celsius, and it is prone to frost injury and striping in cold places in winter. Therefore, before freezing the soil, it is necessary to water the bed surface once, flatten the seedlings to the surface slightly in the same direction, and cover the sand with 5-10cm thick sandy soil, and then cover the sandy soil with grass curtains. After March-April of the second year, the cold protection should be removed in time.

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.

Horticultural DIY: pruning rattan rose (Climbingroses, also known as vine rose) produces two kinds of young branches: the trunk vine branch and the lateral branch that grows at the end of the vine branch. A tall plant must hook or climb against something else, or weave a support for it to lean on so that it does not hang on the ground. If possible, it is best to get the braces ready before planting these rattan roses. During the growing season, they need at least six hours of light and fertile, well-drained soil. Tools and materials 1. Shovel 2. Scaffolding 3. Pruning 4. Compost / fertilizer 5. Choose a bracket for the belt used by the plant. The vine rose produces more flowers when it grows horizontally (as along a fence) than when it grows vertically (such as a flower tower). When choosing scaffolding, also consider whether it is easy to trim and the weight it can support in wet and windy weather. Install scaffolding. It is important to make sure that the scaffolding is firmly fastened to the ground and that the plants are still strong enough when they mature. If you grow on the wall, move the scaffolding 30 centimeters away from the wall to allow good ventilation and easy care. Place the scaffolding upright in the main wind direction or in the corner of the shelter. Plant vines this month. Dig a hole, about twice the width of the root spread, about 0.5 meters deep, and the center of the hole is about 45 to 75 centimeters from the scaffolding. If bare roots are planted, a ball of soil should be made to protect the roots. For grafted joints, the cold winter climate should be placed 5 to 15 cm below the soil, slightly above this level in warmer areas. With different plant species, adjust the horizontal level of the soil accordingly. Water deeply, then spread compost or completely rotten manure and a small amount of phosphorus-rich bone meal around the plant, and water it again. Cover the plants with sawdust, grain husks, etc., but be careful not to accumulate around the rattan rose cadres. Fasten the vines with cloth straps. Choose the strongest vines and tie them together gently with elastic strips of cloth. Separate the vines evenly and keep them at the same level as possible. Nursing and appreciation. Allow these climbers to grow without pruning (except for thinning dead or broken branches) for two or three years. When the plant is mature, prune dead branches, only growing branches, broken branches and dense branches. During the dormant period, trim the floral side shoots. Tips: clematis, a plant 60 to 90 centimeters away from Fujimoto rose, and prune them together to prolong the flowering effect. (turn from flower? The garden? Affection)
