The propagation of the rich tree can be carried out by sowing or cutting, and the seeds should be sown immediately after harvesting, and the cutting can take the sprouted branches as cuttings in May-June; Stick it in sand or steep stones, pay attention to shading and moisturizing, and take root in about a month. In spring, you can also cut off the branches when the plants are cut, plant them in sandy land or coarse sandy land, keep a certain humidity, and take root in about 30 days. However, it is difficult to form swollen roots at the base of cutting, and the ornamental value is not as high as that of sowing seedlings.

Technical key points: The seedbed layout selects sandy loam plot with deep soil layer, fertile soil, sunny leeward and good irrigation and drainage as nursery land, and makes suitable border surface with width 1m, length 10m and north-south direction. Deepen the boundary surface, remove the topsoil and compact it, and lay a layer of 3cm thick gravel on the lower layer. Spraying the bed surface with 400 times solution of 40% formalin for 3 to 5 cm, and covering it with plastic film for 3 days to disinfect the soil and eliminate pests and diseases in the soil.

Cutting collection: select annual semi-lignified branches with strong growth, no pests and diseases and excellent properties, and cut them in cloudy days or windless mornings with a length of 6-7 cm. The lower incision is horseshoe-shaped and located under the leaves or axillary buds. The incision should be smooth, which is conducive to the formation of healing tissue. Generally, each cutting has 2 palm leaves. Be careful not to hurt the leaves to facilitate photosynthesis.

Timely cutting should be carried out from late June to early August, and cutting should be done in the morning and evening. Before cutting, soak half of the cuttings in 25PPM (1) ABT rooting solution for 20-24 hours, take them out and rinse them with clean water. Make a hole in the frame with a small stick, then insert it along the hole, then seal the hole and compact it. Cuttings can be inserted directly when they are short, and obliquely when they are long. The cutting depth is subject to no inclination, generally 3-5 cm. Water in time after insertion, straighten incorrect cuttings, cover them with plastic sheets, and tamp the surrounding with soil.

Ensure the suitable environmental conditions for rooting after cutting at seedling stage. Generally, the soil temperature is 3℃ to 5℃ higher than the air temperature, the relative humidity of the air inserted into the bed is maintained at 80% to 90%, and the illumination requirement is 30%. Ventilation 1 2 times a day. The temperature is high in June and August, and the water evaporates quickly. Spray water with a fine watering can once in the morning and evening, and keep the temperature between 23℃ and 25℃. After the seedlings survive, topdressing should be done in time, with quick-acting fertilizer as the main fertilizer in the early stage, nitrogen and phosphorus fertilizer as the main fertilizer, and appropriate coordination of nitrogen, phosphorus and potassium in the middle stage. In order to promote the lignification of late seedlings, 0.2% potassium dihydrogen phosphate can be sprayed before the end of August to stop using nitrogen fertilizer. Generally, 15 days produces callus, and takes root in about 30 days.

Rich trees like high temperature, humidity and sunshine. Spray water on the leaves with a watering can every 3 to 5 days, which is not only beneficial to photosynthesis, but also makes the branches and leaves more beautiful. Generally, the height of seedlings in that year is 40 ~ 50cm.

Nutrient soil should be prepared before the seedlings are transplanted into the pots of Nostoc flagelliforme trees. 3 parts of humus soil, 2 parts of sand, 4 parts of garden soil, and fully fermented organic fertilizer 1 part are mixed evenly and planted. When transplanting, be careful not to hurt the tender roots, and the depth should be based on the original roots. After planting, thoroughly water the seedlings, put them in a cool place to avoid direct sunlight, and then water them every day according to the soil conditions in the basin. [2]

Sharpay method

1. Seedbed layout: select a nursery with a deep and fertile soil layer and adjust it into a border with a width of 1 m, and the length depends on the quantity. It is appropriate to turn the boundary surface to the north-south direction, remove the topsoil and compact it. The lower layer is paved with a layer of 3 cm thick gravel, and the upper layer is 10 to 65430. Spray the bed surface with 40% formalin for 400 times, and the penetration depth is 3 to 5 cm. Cover with plastic sheets for 3 days to disinfect the soil.

2. Cutting collection: select healthy semi-lignified branches of that year and cut them in cloudy or windless morning. The cutting length is 6-7 cm, and the lower incision is inclined and located under leaves or axillary buds. The incision should be smooth, which is conducive to the formation of healing tissue. Generally, each cutting has two palm leaves, so be careful not to hurt the leaves to facilitate photosynthesis.

3. Fine cutting: the cutting of the rich tree should be carried out from late June to early August, and it should be done on cloudy days or in the morning and evening in summer. When cutting, put half of the cuttings into 25PPM ABT rooting solution (I), soak for 20-24 hours, take them out and rinse them with clear water. Punch holes in the frame with a small wooden stick, then insert cuttings along the holes, and then seal the holes and compact them. Cuttings can be inserted directly when they are short, and obliquely when they are long. The cutting depth is subject to no inclination, generally 3-5 cm. After the cuttings are inserted, water them in time, straighten the wrong cuttings and cover them with plastic sheets.

4. Seedling management: ventilation every three days after cutting. The temperature is high in June and August, and the water evaporates quickly. Spray water once in the morning and once in the evening, keeping the temperature between 23-25 degrees and the humidity about 80% of the field capacity. To promote the lignification of seedlings, 0.2% potassium dihydrogen phosphate can be sprayed before the end of August, and to prevent fungal infection, thiophanate methyl or carbendazim can be sprayed on the border every 7 days. Generally, 15 days produces callus, and takes root in about 30 days.

5. Seedling transplanting: Before seedlings are put into pots, nutrient soil should be prepared, and 3 parts of humus soil, 1 part of sand and 2 parts of garden soil should be mixed for planting. Be careful not to damage the roots when transplanting, and the depth shall be subject to the original roots. After planting, it should be watered and soaked, and placed in a cool place to avoid sun exposure. After that, water it every day according to the soil condition of the basin, so that it is wet when it is dry. [2]

Hydroponics

Small soil-cultivated plants with vigorous growth were selected and cultivated in water by root washing. It is best to add ceramsite as substrate, which can not only fix plants, but also be beneficial to rooting. In the initial stage of hydroponics, fresh water is changed every 2-3 days, and new roots can grow after 2 weeks. When the plants are completely adapted to the environment, add nutrient solution of foliage plants for maintenance, and replace the nutrient solution every 2-3 weeks. If the leaves can be sprayed with 0. 1% potassium dihydrogen phosphate solution regularly during the growth period, it will not only keep the oil tender and green, but also promote the expansion of the stem base.

1, take out the plant, remove the matrix, wash the roots with tap water, and cut off all the roots of the original soil from the root neck;

2. Soak the rhizome base 10- 15 minutes with carbendazim or thiophanate-methyl, and some pathogenic bacteria can be eliminated.

3. Soak the stem base with 200 mg/L NAA solution for 20-40 minutes.

4. Take it out and dry it, put it in a hydroponic planting basket and fix it with pebbles or stones. It should be noted that hydroponics should not have too much water, and it is best to just reach the roots of hydroponic trees. [2]

Sowing method

Rich trees are often sown and propagated. Sowing should use fresh seeds, pick them when autumn is ripe, remove the seed shells and sow them immediately. After sowing, cover it with fine soil about 2 cm thick, and then put it in a semi-shady place to keep it moist. It can germinate about 7 days after sowing. The germination temperature is 22-26℃. When the seedlings grow to about 25 cm, they can be densely planted to make the seedlings grow evenly. Seedlings grow rapidly, so it is necessary to apply thin nitrogen fertilizer at seedling stage and increase phosphorus and potassium fertilizer by 2-3 times to promote the expansion of stem base.

Timing: all seasons are available, and spring is the best.

Seeds can be covered with soil or not, but not too deep. [2]

Water the culture medium from time to time to keep the humidity, which makes it easier to germinate.

This method is easy to cultivate beautiful trees.

This method is slow to copy.

Seed collection should wait until the skin of the fruit turns yellow or dries, otherwise the immature fruit will not germinate and grow smoothly. [2]

Potting technique

Potted god of wealth trees are changed every 1-2 years, and when they leave the house in spring, the yellow leaves and twigs are repaired as necessary.

Cut, in order to promote the germination of its new buds. Watering should follow the principle of intermittent dry and intermittent wet. In spring and autumn, the watering density should be controlled according to the weather, such as sunny rain, wet and dry. Generally, water 1 time a day. When the temperature exceeds 35℃, water it at least twice a day and fertilize it twice a month during the growing season. For new leaves, pay attention to spraying water and maintain a high environmental humidity. Shading should be carried out from June to September, and the light transmittance should be kept at 60%-70% or placed in a place with strong scattered light. After entering the room in winter, the temperature should not be lower than 5℃, and it is better to keep it at about 10℃, water it 1 time for 5-7 days, and ensure sufficient illumination. In addition, in the growing season, if there is poor ventilation, it is prone to the harm of red spiders and scale insects, so pay attention to observation. Pests should be caught or sprayed in time. [2]

Newly introduced plants did not need to change pots or apply nitrogen fertilizer in that year, so as to control the overgrowth of young branches and prevent trees from leaning towards the crown. Rich trees have strong adaptability to water, and they are watered outdoors or indoors for more than ten days.

Water, there will be no floods and droughts that will cause the leaves to turn yellow. Water should be poured indoors every 3 ~ 5 days in summer and every 5 ~ 10 days in spring and autumn. Looking at the room temperature in winter, the soil in the basin is slightly wet. If the room temperature is around 12℃, you can water it once a month. It is resistant to both yin and yang and has strong adaptability.

Under long-term weak light, the branches are thin, the petiole is drooping, and the leaves are light green. Do not change the yin and yang position of the pot in management. They like warm environment and are not cold-tolerant. The suitable growth temperature is 65438 08 ~ 30℃.

Pruning management

If the rich tree is planted outdoors to shade or pick fruit, it does not need pruning, and the annual growth can reach as much as one meter; But if it is planted as a foliage plant in a potted plant, pruning becomes a university question. Because of its amazing growth rate, if it is not pruned, it will easily lead to uneven proportion of trees and affect the beauty of potted plants. After pruning in time, it can not only stimulate its re-germination and growth, but also change its shape, which is a good material for potted beginners. In addition, due to the rapid growth in late spring and early summer, it is easy to recover at this time. For Malabari's modeling design, the author tries to provide the following pruning methods for rich trees for reference:

1. Single plant planting: it is suitable for plants with thick stems, whose stems can be cut off as the base, so that many branchlets can be regenerated from the top of the base and become a miniature flowerpot like a big tree.

2. Braid type: The stems of 2~3 plants are twisted together with iron wire during the growth process to make them grow into braids.

3. Aggregation type: several Malabaric chestnuts with smaller stems are planted in clusters, and the clusters win by quantity.

4. Unique shape: In the process of growing up, it is constantly shaped into a personal favorite shape with wire.

5. Management of the wealth tree: Prune the wealth tree and remove the overgrown branches. When removing robust branches, only 3-4 bud holes can be left at the base, or about 10cm. All other upper branches should be trimmed. Pay attention to all branches on the whole plant. Too weak branches should be pruned from the base, because they sprout weakly and compete with other strong branches for nutrients, so they can't stay.

Don't get wet in the rain, spray water on the pruned branches of the rich tree to prevent rot. Put the pruned rich tree in a bright place or a cool place, and it is required to control watering. Because there is no transpiration on the whole plant, there is less demand for water. Too much watering will rot the root system and lead to the failure of pruning and rejuvenation. Before germination, compound fertilizer with 1-2 times of nitrogen fertilizer can be applied, such as 20- 10- 10 compound fertilizer. During this period, a fungicide is poured to prevent root rot, such as 50% carbendazim wettable powder 800- 1000 times. After one month, the branchlets grow to about 5 cm, and they can be seen in two months.
