Three propagation methods and matters needing attention of Chimonanthus praecox

Many people call wax plum as wax plum, because wax plum is often in full bloom in the cold winter month, so there is this saying. With people's love for wax plum, many flower friends have made breeding and improvement of wax plum, so that there are more and more varieties of wax plum. It's getting easier and easier to grow. If some flower friends want to reproduce Chimonanthus praecox themselves, they can choose the methods of sowing, dividing plants and grafting to propagate.

I. sowing method

1. Autumn sowing: after the fruit is ripe from July to August, the seeds are harvested, and the seeds are taken out of the receptacle and sown at any time. Seedlings can emerge more than 10 days after sowing, and the seedlings can grow as high as 20 centimeters in the same year.

2. Spring sowing: most of the seeds were harvested and stored from March to April. Before sowing, the seeds should be soaked in 30-40 ℃ warm water for 12 hours to promote germination, and then cut in sandy soil and watered enough. Seedlings could emerge in 15-20 days, and flowered in 3-4 years after transplanting.

2. Split-plant method

When the leaf bud begins to sprout (March to April), it can be carried out. The ramet plant should be more than 20cm from the ground, and the top should be cut off at the end of the previous year, so that the mother plant can accumulate more nutrients. When ramets, take out the soil around the mother plant and cut off a part with a sharp knife so that it can be removed and planted.

Third, grafting: cutting is the main method, followed by grafting.

1. Cutting should be carried out every year from March to April when the bud sprouts (such as the size of wheat grains). The scion should be one month ahead of time, and the robust one-year-old branches should be selected from 2-3-year-old wax plum trees, and the middle part of the branches should be cut off. 4 ~ 5-year-old seedlings of Prunus mume or Prunus mume should be selected as rootstocks. Cutting operation: scion length 6-7 cm, leaving 1-2 pairs of buds, cutting off skin on both sides of scion. Slightly see xylem, knife edge bevel length 3 cm 4 cm. Cut off the rootstock 3cm from the ground, cut down at 1x3 on the diameter side of the rootstock, split 4cm, insert the scion into the rootstock, align the scion with the cambium of the rootstock, fasten the interface with a plastic belt, coat it with 2 grams of prepared wet mud, and then cultivate the soil to the top of the scion to moisturize.

2. Docking: docking operation: it is best to do docking between May 6 and 21 every year. The rootstock was placed on the side of the excellent varieties of Chimonanthus mume, and the branches with the same thickness were selected as scions. Cut the branches of the selected rootstock and scion with a sharp knife, each with a cut of 3 cm and 9 cm, paying attention to the xylem. The cut position of the rootstock should not be too high, and it is better to be less than 20cm. After the incision is cut, the wound of the rootstock should be relatively close to the wound of the scion, especially the cambium of the two sides should be attached to each other, then tie it up slightly with rope, put wet mud on the joint, and then wrap it with plastic film, and then make appropriate light cutting of the branches on the rootstock, but do not amputate the top so that it can continue to grow and provide water and nutrients to the scion. After 40 days, when new leaves and branches grow on the scion, the branches of the scion can be cut off from the lower part of the incision, and all the branches and leaves above the cut of the rootstock can be cut off, so as to become an independent plant.

Seed planting methods and matters needing attention of Chimonanthus praecox

Chimonanthus has a very long history and is very popular. It is not only of high ornamental value, but also can be used as medicine. The propagation of Chimonanthus chinensis is generally based on grafting, and it can also be divided, sown, cut and striped. Today, Xiaoqi is going to tell you about this sowing and reproduction. How to plant the seeds of Chimonanthus praecox? Let's get to know each other.

How to plant the seeds of Chimonanthus mume

If you want to know how to plant Chimonanthus seeds, you should first understand in what environment it likes to grow in order to grow. Winterberry is sunny, shade-resistant, cold-resistant, drought-resistant, and avoid waterlogging. Wax plum blossoms proudly open in frost and snow cold weather, yellow flowers like wax, strong fragrance, is the main ornamental flowers and trees in winter. Lamei is afraid of wind and cold, and can survive the winter safely at no less than-15 ℃. It can be cultivated in open field in the south of Beijing. It grows on slightly acidic sandy loam with deep, fertile, loose and well drained soil, and grows poorly on saline-alkali soil.

2. Seed planting methods of Chimonanthus praecox

1. Watering: wax plum likes sunshine, but it is also slightly resistant to shade, cold and drought. Therefore, there is a flower proverb of "wax plum that cannot be killed by drought, citrus that cannot be drowned". It is appropriate to choose light loam with slightly fertile and well-drained soil. Potted Wintersweet requires meticulous management and is generally cultivated in fertile sandy loam. The soil would rather be dry than wet. Too much watering will lead to physiological fallen leaves.

2. Fertilization: the application of fertilizer depends on the growth of the plant, generally applying some dilute dung water every month. When the temperature turns low in September, the application of concentrated fertilizer and phosphorus and potassium fertilizer can be added, which is beneficial to flowering.

In the management of flowering period, Chimonanthus przewalskii promotes flowering, which is treated by the following methods: potted Chimonanthus przewalskii with strong branches in early June and chicken dung after about 10 days, the flower buds are as big as rapeseed. When chicken manure was applied again in late June, the buds gradually increased. By mid-July, the leaves fell off one after another and began to spray water four times a day. A shade was built in mid-July and opened at 5 p.m. After low temperature treatment in late August, the temperature gradually decreased from 12 ℃ to 4 ℃, and then increased from 4 ℃ to 12 ℃. After 16 days of low temperature treatment, the buds developed into round and bluish yellow. It was taken out from the freezer in mid-September. One pot was placed between 28030 ℃.

3. Pruning in order to form a good branch, attention should be paid to pruning and shaping to make it more branched. After the flowers fade, they should be pruned in time, leaving only 15cm to 20cm in length for each branch to grow stout. The flower proverb "Chimonanthus is not short of branches" means that Wintersweet is heavily cut. There are still no fallen leaves in October, which can be removed manually to reduce nutrient consumption and promote early flowering. At the same time, in order to ensure full bloom next year and reduce nutrition consumption, the flowers are often removed before withering and do not bear fruit.

4. prevention and control of diseases and insect pests: the diseases and insect pests of Chimonanthus are mainly harmed by longicorn beetles. the control methods are as follows: according to the activity habits of adult longicorn beetles, artificial hunting and cutting off the damaged branches and shoots as early as possible, and eliminating eggs and newly hatched larvae before and after the Summer Solstice. Hook larvae and use drugs to block wormholes to kill larvae. Harvesting, processing, storage.

The above is the introduction of Chimonanthus seed planting methods. I hope it will be helpful to you. However, Chimonanthus generally does not need to sow and reproduce, because it is difficult to maintain the excellent characteristics of the female parent, and there are more asexual reproduction with ramets, cuttings and so on.

Cultivation and Culture of Chimonanthus in the United States Chimonanthus is a species of the genus Chimonanthus of the family Chimonanthus. Deciduous shrubs. Like warm, moist and semi-overcast environment. Not resistant to cold and drought, afraid of strong light and flooding. Suitable for fertile, moist, organic matter-rich sandy loam. It is suitable for cultivation in the south of the Yangtze River basin. Can be potted ornamental, layout balcony, courtyard and other places.

The culture method of Chimonanthus chinensis can be used in the culture of Chimonanthus chinensis by sowing, plant division, grafting and so on. Sowing takes place from March to April in spring. Ramet can be combined with spring transplanting, the method is to split the tufted plants with a sharp knife, and then plant them separately. The seedlings of Chimonanthus chinensis or other strong varieties of Chimonanthus chinensis can be used as rootstocks for grafting, split grafting in March and bud grafting in August. Cultivation and management of Chimonanthus mandshurica is native to the southeastern United States, likes a warm and humid environment, grows well in sufficient and soft sunlight, but is afraid of hot sun exposure and is resistant to cold. Suitable for planting under sparse forests or other places where there is no direct sunlight in summer, if the light is too strong, the petals will dry up and form ugly scorched spots. In addition, the dry and hot wind during the flowering period will also cause the petals to scorch, so try not to plant at the tuyere. Too dry air is also an important reason for the petals to scorch, so if the air is dry during the flowering period, water should be sprinkled to the plant and its surrounding environment in time to increase air humidity and prolong the florescence. Chimonanthus mandshurica is not strict with soil, but grows better in loose, fertile, well-drained soil. The growing period can be fully watered to keep the soil moist, but pay attention to drainage on rainy days, so as not to cause rotting roots due to stagnant water in the soil. Before sprouting, mature organic fertilizer or compound fertilizer can be applied once every spring, and water should be watered once after fertilization to facilitate plant absorption of nutrients, promote germination and leaf expansion, and provide sufficient nutrients for plant flowering. After that, fertilizer and water mainly based on phosphorus and potassium fertilizer were applied once a month to promote plant growth. Stop fertilizing after September, so as not to overgrow the plant and not enrich the branches, which will affect the overwintering. Pour frozen water once before winter. The pruning of Chimonanthus chinensis should be carried out in the dormant period from winter to early spring, cutting off dry and withered branches, overlapping cross branches, thin and weak branches to renew branches, proper pruning after flowering, cutting off over-dense branches, and slightly pruning during the growing period to remove some branches that affect beauty, so as to maintain the beauty of the tree shape and increase the ventilation and light inside the crown.
