Queen's sunflower is also known as golden wasabi, horseradish, queen coconut, and Kleba coconut. Its scientific name is Syagrus romanzoffianum (Cham.)Glassm.

[Family and Genus] Palm family Phoenix tail palm It is an evergreen tree with solitary and erect stems, more than 10 meters in height, the middle and upper parts are slightly enlarged, smooth and ring-shaped, pinnately compound leaves, fully lobed, 2-5 meters long, with many lobes, linear-lanceolate. green.

[Distribution] It is native to Brazil, Argentina, Bolivia and other countries. It has been introduced and cultivated very early in Guangdong, Guangxi, Fujian, Hainan and other places in my country.

[Habits] Likes a warm, humid, sunny and ventilated environment. The suitable growth temperature is 22-28 degrees Celsius. It can withstand low temperatures of -2 degrees Celsius and can withstand low temperatures below -5 degrees Celsius for a short period of time. It requires fertile and Moist soil has strong wind resistance, salt-alkali tolerance, and drought tolerance.

[Reproduction] Reproduction by sowing seeds. The fruits mature the same year or the following year. The dry weight of the fresh fruit is about five kilograms. After the fruit is harvested and soaked, the pulp is removed, and the seeds are sown on the seedbed and covered with 1-2 cm thick fine sand. Keep them moist after sowing and germinate after 2-6 months. The germination type of Queen's bud seeds is adjacent type and primary leaf Wei full edge subtype. Seedlings grow slowly and cannot be transplanted until the following year.

[Cultivation] Queen's sunflower prefers a warm, humid and sunny environment, and requires deep, loose, and well-drained soil. Wait until the seedlings are 50--60 centimeters tall before planting in the field. Although the queen's sunflower is managed extensively, fertilizers must be added regularly during the growth period. In the dry season, you can water it appropriately to ensure its vigorous growth. There are few pests and diseases.

[Application] The trunk of Queen's Sunflower is tall and straight, and the leaves clustered on the top are like loose feathers, which resemble the crown on the queen's head. It can be used as a garden ornamental or street tree. It can also be used as a coastal greening tree species.

Common cultivated species of the same genus include: Five-row Queen Coconut, which is 12 meters high, 25 centimeters in diameter at breast height, with 30 pinnate leaves, slightly spirally arranged into 5 longitudinal lobes, and 3 meters long. It is drought-tolerant and barren-tolerant and can be planted in parks as the main landscape plant. Because of its medium-sized tree, it is also particularly suitable for garden beautification. Originated from Brazil. How to propagate roses

Many florists see beautiful roses and don’t know how to propagate roses. Compared with roses, roses are easier to propagate because the survival rate of rose cuttings is very high. Of course, besides propagating roses from cuttings, they can also be propagated. You can choose methods such as layering, division, or even sowing, but for ordinary flower lovers, cutting is the simplest and fastest method.

Rose cutting propagation can maintain the inherent characteristics of the variety, achieve rapid propagation in a short period of time, and is easy to operate. Therefore, it is often used in rose propagation. Here are some key points of rose cutting propagation for flower lovers: < /p>

1. Cutting time: except summer, other times are acceptable.

2. Selection of branches: Disease-free branches from the previous year can be used (semi-lignified ones are best).

3. Treatment of branches: Branch thickness (0.2cm-.08cm diameter is acceptable), length (8cm-15cm length is acceptable), leave 3-4 sections, and bury 1-2 sections in the soil.

4. Cutting medium: Pure vermiculite or perlite can be used for cuttings if conditions permit. Ordinary garden soil can also be used if conditions are unavailable.

5. Management after cutting: Appropriate shade after cutting, no need to take careful care. Propagation and cultivation techniques of plum blossoms

Plum blossoms, also known as spring plums, belong to the Prunus genus of the Rosaceae family. They are deciduous trees with luxuriant branches and graceful shapes. From February to March, the plum blossoms are in full bloom and colorful. They are the most popular place in cities and towns. One of the commonly used tree species for landscaping and home flower cultivation. Plum blossom propagation is often based on grafting, but layering and cuttings can also survive. When cultivating new varieties and cultivating rootstocks through crossbreeding, sowing propagation can also be used.

1. Grafting and Propagation Grafting is the most commonly used method to propagate plum blossoms, and the survival rate is extremely high. The rootstocks can be peach (peach, mountain peach), apricot and plum seedlings or the roots of peach and apricot.

1. Spring grafting. Before germination in early spring, cutting grafting, subcutaneous grafting (for larger rootstocks), bud grafting (including ventral grafting of long pieces of small buds), cleft grafting, etc. can also be used.

2. Grafting in summer. Before the first new shoot matures and the second new shoot germinates, cleft grafting of the scion with leaves is performed. Split grafting is suitable for multi-species grafting or high branch crown replacement, but it must be bagged to moisturize and shade.

3. Grafting in autumn. It is advisable to use abdominal grafting in winter, preferably with long pieces of small buds and fully closed abdominal grafting. This method is simple to operate, heals well, has a high survival rate, and is not easily broken by wind. If it does not sprout that year, when the sap begins to flow the next spring, just poke a small hole at the eye of the bud and the bud will sprout.

4. Grafting in winter. The method of using root grafting in winter is very effective: during the winter dormancy period, carefully dig out the strong new roots of peach, apricot or peach that are free of diseases and pests (1 cm in diameter or larger), try to retain the fibrous roots, and then cut them into 10-15 pieces. Centimeter-long pieces are reserved. The thick ones are cut and subcutaneously grafted, and the thin ones (about 1 cm in diameter) are split grafted. After grafting, they are planted in sandy loam soil in the leeward direction that does not accumulate water. Cover the binding area with soil and water it thoroughly. If managed extensively in winter, it will germinate in the following spring. This method of grafting germinates early and grows quickly. The new plant will bloom 1-2 years after grafting.

2. Cutting seedlings should be grown in November-December after the leaves fall or after flowering in early spring. Cut off one-year-old thick branches (without flower buds), 10--18 cm long, and insert them into the sandy loam soil seedbed. The part embedded in the soil is about It is 1/2, and the spacing between plants and rows is 10 cm and 20 cm. After planting, keep it at half moisture and pay attention to watering and other management work. Spring transplanters must build a shade shed during the summer period.

3. Layering propagation: In February-March, select strong 1-3-year-old branches, dig a deep trench next to the mother plant, make 3 shallow cuts below the bend of the branch, and then cover with soil. Press bricks on top and cut off the mother body after taking root. For high pressure, you can select appropriate branches on the mother tree and slightly scratch them during the moldy rain season, wrap some mixed soil with plastic film, and tie both ends tightly to maintain the temperature. Check after 1 month. If the roots have taken root, you can make an incision under the layering, reaching as deep as the middle. After another 20-40 days, all the roots will be cut away from the mother body and moved to the field for cultivation.

4. Sowing and Propagation: Harvest the fruits from June to July, spread them before ripening, wash out the seeds and dry them. Drill sow in autumn or early spring, with a spacing of 10 cm to 25 cm between rows. How to propagate purple peony

Select the strong tillering branches of the annual peony and cut them into cuttings with 2 to 3 buds around September. Use NAA naphthylacetic acid (NAA) (500 mg/L) Or quickly dip IBA indolebutyric acid (IBA) (300 mg/L) for 1-3 seconds, and cut the cuttings on sandy loam soil. Adventitious roots can be produced in 20-30 days at 18-25 ℃, and 6 roots will be formed after 2 months. ~10 cm long root system; 15-20 days after peony blooms, take a single bud stem from the middle of the stem as a cutting, insert 5-6 cm into a clean river sand substrate, keep the substrate moist, place it in a shaded place, and cover it with 3-4 cm of river sand and 10-20 cm of litter can be transplanted in the following spring, and the rooting rate can reach 90%.

Although peony cuttings can survive, they grow slowly and are difficult to care for. Many technologies in specific operations are not mature enough and are generally rarely used in production. However, peony cutting propagation can improve the reproduction coefficient. Before the success of peony tissue culture, peony cutting propagation will be the development direction of peony rapid propagation and peony industrialization based on the use of modern seedling technology and advanced equipment.
