Production and maintenance of bonsai of Carthamus tinctorius

Safflower threshold wood is often used to make bonsai, can be made single-stem, double-stem, dry, curved and jungle and other different forms of bonsai, crown can be processed into natural shape, can also be processed into different sizes, scattered round shape, processing methods can be used Pan tie, pull and pruning and other means, let's take a look at the production and maintenance of safflower chinese-tree bonsai!

Propagation method of safflower stepwood

Grafting: Grafting is mainly carried out by two methods of cutting and budding, which can be carried out in February to October. It is better to cut before germination in spring, and budding should be carried out in September to October. The medium and small plants of Loropetalum chinense L. were used as rootstocks for multi-head grafting, and water, fertilizer and pruning management were strengthened, so that they could be planted in one year.

2, cuttage: cuttage in March to September can be carried out, choose loose loess for cuttage matrix, ensure that cuttage matrix ventilation and high air humidity, keep warm but avoid direct sunlight, while paying attention to cuttage environment ventilation. Under warm and moist conditions, cuttings formed red healing bodies in 20~25 days, and 3~9 new roots with a thickness of 0.1 cm and a length of 1~6 cm grew after 1 month.

3, sowing: spring and summer sowing, seed germination rate is high, germination about 25 days after sowing, 1 year can grow to 6~20 cm high, pumping 3~6 branches. The new roots of seedlings are red and fleshy, and must be carefully managed in the early stage until the roots are lignified and brown. Sexual reproduction is usually not used for seedling production because of its long seedling stage, slow growth and appearance of white Loropetalum chinense seedlings (atavism), but for breeding research of safflower steptree.

Making of potted plant of Loropetalum chinense

1, solitary plant: select tall and plump plants solitary plant in an important position or focus of sight, such as the vicinity of the entrance, courtyard or lawn, independent into the scene, and pay attention to the strong contrast with the surrounding landscape, in order to achieve the effect of "a little red in the green", can play the role of the central point of view of the landscape or guide the line of sight.

2. Cluster planting: Safflower tree balls and other plants are dotted in clusters in the garden green space, which not only enriches the landscape color, but also enlivens the garden atmosphere. If planted with green tree species, can play a icing on the cake role, with safflower as the main tree species planted in groups, constitute a landscape forest, unique leaf color and posture are very beautiful all year round, its beautification effect is far better than pure green landscape forest.

3. Group planting: The seedlings of annual safflower stepwood are densely planted in green land to form color blocks, which can be matched with golden leaf privet, spring flower rhododendron, summer flower rhododendron, golden leaf elm, golden yellow boxwood, etc., which can not only form color contrast through leaf color contrast, but also stagger flowering period. For such purposes, it is advisable to select red lines of Tougu.

4, spherical: the safflower tree will be trimmed into a spherical arrangement in the green belt, mainly divided into two types of hair ball and sperm ball, hair ball is mainly after 1~3 years of pruning modeling, mainly used in the management of a little extensive green space, sperm ball at least after 3 years of pruning modeling, mainly used in villa courtyard and other delicate gardens, such uses should be selected red line.

5, color fence: with safflower wood dense planting color fence play a role in enclosure and separation space. Seedling specifications should be selected according to the specific use of color hedges, such as 70~80 cm color hedges in green space, and color hedges higher than 2 meters are mostly used to function as green fences on the periphery of green space.

6. Color carving: The safflower stepwood is directionally cultivated or shaped into green sculptures such as animals and geometric shapes, and placed in green land as garden accessories. For such purposes, the red line of Tougu should be selected.

7, pile scene: the use of double-sided red safflower tree growth fast, large leaves, sparse characteristics, its directional cultivation for large pile scene, used for high-grade garden greening, can also be used as the focus of flower beds to set.

8. Street trees: Cultivate safflower steptrees into small trees with colorful leaves through pruning control, or cultivate them by grafting with white Loropetalum chinense. They are mostly used as street trees in small areas. For such purposes, it is advisable to select red trees.

Maintenance of potted plant of Loropetalum chinense

1. Soil: Loropetalum chinense likes acidic soil. If the soil is too alkaline, it will make Loropetalum chinense bonsai grow poorly until it dies. It is ideal to culture Loropetalum chinense with river sand, coal ash and yellow loam 3:2:5, or with river sand yellow loam 3:7 or sandy yellow loam, and a layer of coarse sand or ceramsite with good drainage at the bottom.

2. Pruning: pruning and shaping is particularly important for raising the potted plant of Loropetalum chinense. In order to ensure the ornamental type of potted plant of Loropetalum chinense, it is necessary to cut off the overlord branches, excessive long branches, clustered branches, weak branches in the inner hall, pest branches, etc. during its growth period, and pruning and picking leaves at the growth points of Loropetalum chinense chinense can adjust the flowering or red leaf period. Re-pruning should be done before or after full bloom or early autumn, combined with pot turning, the effect is better. After flowering, cut off the remaining flowers and fruits as soon as possible to avoid consuming nutrients.

3. Turning over the pot: turning over the pot is conducive to the growth of safflower Chinese loropetalum. When turning over the pot, pay attention to pruning the old roots, excessive roots, overlapping roots, twisted roots, thinning and over-dense roots, removing rotten roots and dead roots, removing old soil and replacing new soil. The interval between pot turning is 3~4 years for large pots, 2~3 years for medium pots and 1~2 years for small pots. Special circumstances can be carried out at any time.

4. Fertilization: Safflower Loropetalum fertilizer adhere to the principle of thin fertilizer and more fertilizer, diluted cake fertilizer can be applied twice a month during the growth period, 1% urea can be added in between, potassium dihydrogen phosphate 800~1000 times solution can be sprayed before flowering to promote flower bud differentiation, enhance flower color, flowering and dormant period do not fertilize, 0.5% ferrous sulfate solution should be sprayed once every season to keep the soil acidic. Fertilization should be carried out on cloudy days or sunny evenings.

5. Watering: The watering of safflower chinchilla potted plant depends on the season, climate, pot size, and flexible control of plant growth status.
