Propagation methods of Carthamus tinctorius

Carthamus tinctorius has strong adaptability, cold tolerance, drought tolerance, pruning resistance, and is also very suitable for banding and shaping. Now many flower friends will plant it indoors and have a special flavor. The planting difficulty of Carthamus tinctorius is not high, and the methods of sowing, cutting, grafting and high pressure can also be used for propagation, and the survival rate is also very high.

Redrlowered Loropetalum

1. Sowing and propagation of Carthamus tinctorius: adult plants with strong growth from 9 to 10 years were selected and picked in batches from late September to early October, when the capsule was not yet cracked, picked in batches, shelled and sown after harvest, and sowed in autumn and winter from November to December. Spring sowing is better in early March. Soak the seeds in warm water for 1-2 days before sowing, or soak the seeds with 500/1000000 gibberellin for 30 minutes. The sandy soil with good drainage and rich and loose soil was selected as the border, with a width of 1.2 meters, a height of 15 centimeters, and a row spacing of 5 centimeters × 10 centimeters. After sowing, the soil was covered with fine loess sand with a thickness of 1.5 centimeters and covered with silk thatch. Generally, seedlings emerge in about 25 days, during which attention should be paid to the prevention and control of blight. When the seedling grows to about 15 cm, it can be transplanted. It can blossom after 2-3 years of growth and bear fruit after 5-6 years. The leaves of seedlings turn green seriously, and most of them are not used in seedling production, but mainly for variety selection.

Second, cutting propagation of Carthamus tinctorius: select well drained, sunny, deep, fertile soil or dry soil to make a cutter with a width of 1.5 meters, a height of 10 centimeters and a length with the topography. The matrix should be mixed with 50% fine yellow mud, 10% tidal sand mud and 40% bran ash. The branches with sturdy and full development, protruding nodes and prominent bud eyes were selected from the robust mother plant. According to the Lignification degree of branches, it can be divided into three types: tender wood cutting (or green wood cutting), hardwood cutting and old wood cutting. The cuttings are generally 4-5 nodes, about 10 cm long, retaining the upper 1-2 leaves, and the base is cut into horse ear shape. Then it was treated in rooting agents such as 300/1000000 naphthylacetic acid, 200/1000000 to 300 abt or 300/1000000 to 500 indoleacetic acid for 5 minutes, and then inserted into the wet substrate. After insertion, it is fully watered with a fine-hole sprinkler, and then sealed with a thin film to maintain high temperature, high humidity, proper light and air permeability in the shed. After 20-30 days, the callus was produced from the wound at the lower end of the cuttings, on which a large number of small roots sprouted, and shoots and leaves were drawn in the shed, and the roots reached more than 90% after 50 days, and the film could be removed. Generally, the height of the seedlings in the same year is 15-20 cm, and there are 2-3 branches, which can be transplanted.

Third, Carthamus tinctorius grafting propagation: the affinity between red shackle wood and shackle wood is particularly strong. Grafting method is often used to make red shackle wood bonsai and large size red shackle wood green seedlings. The common methods are as follows: 1. Cutting: it is suitable for grafting in spring and autumn. One-year-old or current-year branches with full buds and a certain thickness were selected in the middle and upper part of the robust mother tree, and the apparent Internode length of each scion was generally 2-3 buds and 2-2 in total length. Five centimeters would be better. The flat side is selected as the long cutting side, and the cortical microstrip xylem is cut off with a length of 1. 5: 1. 6 cm, tilting about 15 degrees. The short cutting surface is on the opposite side of the long cutting surface, the length is 1/3 of that of the long cutting surface, and the inclination is about 60 degrees. The cutting of the rootstock requires a smooth cut and a slight tilt to one side. First hit a corner knife upward on the low oblique side, then cut the xylem longitudinally, 1.5 cm to 1.6 cm long, and then cut the length of the scion inward and align it with the cambium. If the ratio difference between the rootstock and scion is large, it should be aligned to one side to form the layer. Then wrap it with a ribbon film and cover the upper part of the scion with a thin film bag. When the rootstock is many times larger than the scion, it can be sealed by the mud ball method, that is, after that, it is entangled with film tape, but not capped, and then at the joint of the rootstock, the moist fine loess is pinched to grow an oval mud ball, which is tightly wrapped with a film of 5 inches long and 4 inches wide, wrapped with rope thread, and only a few leaves are exposed outside the mud mass. The scion can be isolated from the hot and dry climate of the outside world in the mud mass, improve the survival rate and prolong the grafting period. 2. Budding: this method is often carried out in summer and autumn, and the general budding has t-shaped and h-shaped. In the selected part of the bud, cut it into a t-shaped or h-shaped, deep into the xylem, gently open the cortex to separate it from the xylem, and then on the branch of the scion, cut off the leaves below the bud, leaving only the petiole. The grafted bud is cut into a microwoody shield bud, which is about 1cm long and 1.2 cm long, and then embedded into a t-shaped or h-shaped incision on the rootstock, leaving the petiole out when bound. After 7-8 days, the petiole was gently touched and then fell off, indicating that the grafting had survived. Management of grafted seedlings: unwinding film after survival, timely erasing tillers and cutting rootstocks, strengthening the management of loose soil and weeds, paying attention to drainage and irrigation in dry season, timely and appropriate fertilization, and preliminary coring and plastic surgery as needed.

4. High-pressure propagation of Safflower: when buds are found on red shackles, or when the stout branches of red shackles are used to cultivate small pile blanks of small and miniature bonsai, mud bagging + abt (2) ring peeling high-pressure method is commonly used. In the middle of April, the girdling width is 3 / 5 times of the diameter of the high-pressure branch, the concentration of abt (2) is 50/1000000, the diameter of the film mud bag is 3 / 5 times of the diameter of the high-pressure branch, and the height is 6 / 8 cm longer than the girdling width. The upper part of the bag is fastened to prevent Rain Water from being immersed. In October of that year, it was cut and planted in the nursery, and the survival rate was 80% to 90%.

Culture method of Carthamus tinctorius

Carthamus tinctorius, scientific name: Lorpetalum chindensevar.rubrum alias red shackle wood, saffron flower. Evergreen shrubs or small trees of Hamamelidaceae. Mainly distributed in the middle and lower reaches of the Yangtze River and the south, northern India.

Carthamus tinctorius likes light and is slightly shade-resistant, but the leaf color is easy to turn green when it is shady. Strong adaptability and drought tolerance. Like warmth and withstand the cold. Strong sprouting and branching, resistant to pruning. It is resistant to barren, but it is suitable to grow in fertile, moist slightly acidic soil.

In order to promote the growth of new shoots, the neutral foliar fertilizer 800 / 1000 times dilution was used to top up the leaves in the growing season and sprayed 2 times per month. In the southern plum rain season, attention should be paid to keeping good drainage, high temperature and drought season, watering one time in the morning and evening, and cooling by spraying water at noon; in the north, because the soil and air are dry, the soil must be watered in time to keep the soil moist, spray water in autumn, winter and early spring, and keep the leaves clean and moist.

Trim. Castanopsis carlesii has the characteristics of strong germination and resistance to pruning. Light to moderate pruning in early spring and early autumn, combined with normal water and fertilizer management, can blossom after about 1 month, and the flowering period is concentrated. This method can promote the development of new branches and leaves, make the tree more beautiful, prolong the red period of leaves, and promote and control the florescence, especially suitable for red rosewood bonsai to participate in flower exhibitions and trade fairs, which can enhance the exhibition effect. Promote product sales.

Pick leaves and wipe tips. In the growing season, the mature leaves and shoots of Castanopsis carlesii are removed and the tender shoots can be extracted again after normal management for about 10 days, and bright red new leaves can grow.

Choose sunny environment for cultivation, or prune the plants arranged in the southeast and above of the tree, so that the tree can grow healthily in sufficient sunlight and make the flowers and leaves more beautiful, so as to enhance the ornamental.

The propagation methods of Loropetalum chinense are mainly tissue culture, grafting propagation, sowing propagation and cutting propagation, among which grafting propagation and cutting propagation are more commonly used. Grafting propagation mainly uses two methods: cutting and budding. Grafting can be carried out in 2 ~ 10 months, cutting should be carried out before germination in spring, and bud grafting should be carried out from September to October. The small and medium-sized plants of Castanopsis carlesii were used as rootstocks for multi-head grafting to strengthen the management of water, fertilizer and pruning, which could be out of the nursery within one year. Http://www.yuhuagu.com cutting propagation can be carried out from March to September. Loose loess is selected as the cutting substrate to ensure that the cutting substrate is ventilated, permeable and high air humidity, keep warm but avoid direct sunlight, and pay attention to the ventilation and ventilation of the cutting environment. Under warm and humid conditions, red cuttings formed red callus in 20-25 days, and 3-9 new roots with thick 0.1cm and long l~6cm grew after 1 month. The propagation coefficient of the cutting method is large, but the growth is weak and the time of coming out of the nursery is long, while the seedlings grafted with many heads grow strongly and come out of the nursery quickly, but it is more labor-consuming. After sowing and sowing in spring and summer, the seed germination rate of Castanopsis carlesii was high, and it germinated about 25 days after sowing. It could grow to a high 6~20cm in 1 year and sprout 3-6 branches. The new roots of Castanopsis carlesii seedlings are red and fleshy, which must be carefully managed in the early stage, and can not be managed extensively until the roots become lignified and brown. Because of its long seedling stage, slow growth and the emergence of albino seedlings (atavism), sexual reproduction is generally not used in seedling production, but in red oak breeding research.
