Planting methods and key points of cultivation and management of medlar bonsai

Chinese wolfberry is an evergreen tree of holly family holly, other cat thorn, tiger thorn, etc., produced in China's Yangtze River basin, Qinling Mountains and other parts of the south, the growth is very slow, mostly distributed in hillsides, valleys, stream side trees or shrubs, cultivated in Qingdao and Jinan, Shandong Province, with high cultivation value, let's take a look at the planting techniques of wolfbone.

The growth habit of Lycium chinense

Chinese wolfberry is grown in Jiangsu, Shanghai, Anhui, Zhejiang, Jiangxi, Hubei, Hunan and other provinces, Yunnan, Kunming and other city gardens, as well as botanical gardens in Europe and the United States. Like light, slightly resistant to shade, like warm climate and fertile, moist and well-drained micro-acid soil, cold resistance is not strong, can adapt to the urban environment, strong resistance to harmful gases, slow growth, strong sprouting ability, resistant to pruning.

The Propagation Technology of Fructus Lycii

The main results are as follows: 1. Sowing: the mature seeds can be collected from September to October, and the seeds can not germinate until 3 months after ripening, stored with sand stratification, and sowed in March to April of the following year, the emergence rate is higher. If the Chinese wolfberry has a variety with colored markings, the seedlings will atavistic and the leaf color will turn green.

2. Cuttage: both hardwood and softwood cuttings are available, usually in the rainy season, with high survival rate. Cuttings are cut from plants with rich fruit and strong growth, with a length of 12 cm to 15 cm and a depth of 8 cm to 10 cm. In order to promote rooting and improve the propagation effect of cuttings, the cuttings should be treated before cutting. if there are conditions, the use of ABT2 rooting powder can greatly improve the rooting rate.

3. Grafting: the grafting propagation of Chinese wolfberry is mainly used for the reproduction of leaf species with colored markings, which is usually carried out before sprouting in spring. With Chinese wolfberry as rootstock, the survival rate is high by splicing or bud grafting.

Planting technique of Chinese wolfberry

1. Transplanting: the transplanting of Chinese wolfberry can be carried out in spring and autumn, and it is better to transplant with soil from March to April in spring or autumn. Due to the scarcity of Chinese wolfbone whisker root, it is necessary to specially prevent loose balls during operation, and at the same time cut off some branches and leaves to reduce transpiration, otherwise it is difficult to survive.

2. Watering: the Chinese wolfbone needs to be watered frequently during the vigorous growth period, it is generally necessary to keep the basin soil moist and without stagnant water, and it is often necessary to spray water to the foliar surface in summer to facilitate evaporation and cooling.

3. Fertilization: Chinese wolfberry is generally applied with thin cake fertilizer once every two weeks in spring, topdressing once a month in autumn, no fertilizer in summer and once in winter.

4. Pruning: the medlar bone has a strong germinating power and is very resistant to pruning. For Chengjing's works, unnecessary overgrown branches, germinating branches and redundant buds can be cut off to maintain a certain tree shape. For the trees that need to be processed, some branches can be retained according to the needs to facilitate processing and shaping.

5. Turning the basin: the bonsai is usually turned once every 2 to 3 years, often in February to March in spring, or when the trees enter the dormant period after autumn. When turning the basin, you can trim off part of the old roots, apply sufficient base fertilizer, retain the old soil of 1x2, and put it back on the basin.

Management methods and key points of planting and cultivation of Lycium chinense

Lycium chinense is an excellent species of foliage and fruit tree, which does not wither through winter. At the same time, it also has high medicinal value, and its leaves, fruits and roots can be used as medicine. So, how to plant the wolfbone tree? In this paper, the planting and cultivation management methods and key points of Lycium chinense are introduced as follows.

I. cultivation methods of Lycium mongolicum

1. Sowing: the mature seeds of Lycium chinense can be collected from September to October, and the seeds can not germinate until they are ripe for 3 months, stored with sand stratification, and sowed in March to April of the following year, with a high seedling emergence rate. A variety of Chinese wolfbone trees with colored markings, the seedlings will atavistic and the leaves will turn green.

two。 Cutting: Chinese wolfberry hardwood and softwood cuttings are available, generally in the rainy season for softwood cuttings, the survival rate is high. Cuttings are cut from plants with rich fruit and strong growth, with a length of 12 cm to 15 cm and a depth of 8 cm to 10 cm. In order to promote rooting and improve the propagation effect of cuttings, the cuttings should be treated before cutting. if there are conditions, the use of ABT2 rooting powder can greatly improve the rooting rate.

Second, the key points of the management of Chinese wolfberry.

1. Transplanting: the transplanting of Chinese wolfberry can be carried out in spring and autumn, and it is better to transplant with soil from March to April in spring or autumn. Because Chinese wolfbone tree whisker root is rare, the operation should especially prevent loose balls, while cutting off some branches and leaves, in order to reduce transpiration, otherwise it is difficult to survive.

two。 Temperature: like warmth, the most suitable temperature for growth is 13-18 ℃. The cold tolerance is strong, it can endure a low temperature of-8 ℃ in winter, and the cold resistance is weakened in potted plants. when it is lower than 0 ℃ in winter, it is best to move the pot plant indoors to survive the winter. It is also not suitable for high temperature and hot weather, and the plant grows slowly when it is more than 35 ℃.

3. Light: like plenty of sunshine, but also very resistant to shade.

4. Watering: the Chinese wolfbone tree needs to be watered frequently during the vigorous growth period, it is generally necessary to keep the basin soil moist and without stagnant water, and it is often necessary to spray water to the leaves in summer to facilitate evaporation and cooling.

5. Fertilization: the Chinese wolfbone tree is generally applied with thin cake fertilizer every two weeks in spring, topdressing once a month in autumn, no fertilizer in summer and once in winter.

6. Pruning: the Chinese wolfbone tree has a strong germinating power and is very resistant to pruning. For the works of Chengjing, unnecessary overgrown branches, germinating branches and extra buds can be cut off to maintain a certain tree shape. For the trees that need to be processed, some branches can be retained according to the needs to facilitate processing and shaping.

7. Turning the basin: the bonsai of Chinese wolfberry is usually turned once every 2 to 3 years, often in spring from February to March, or when the trees enter the dormant period after autumn. When turning the basin, you can trim off part of the old roots, apply sufficient base fertilizer, retain the old soil of 1x2, and put it back on the basin.

8. Pest control: there are diseases and insect pests such as lacquer spot, leaf spot, powdery mildew and shell insects.

[editor's conclusion] Goji likes fertile acidic soil and is not tolerant to salt and alkali, so special attention should be paid to it in the process of maintenance. The above introduces the planting and cultivation management methods and key points of Chinese wolfbone tree, hoping to help you!

Key points of Flower cultivation and Management in Autumn

China Garden Network, Oct. 15: all flowers that have passed through the high temperature season have entered a growth peak in autumn, when the sun is abundant and the temperature is suitable, so the supply of fertilizer and water should be increased. so that flower plants have a strong nutrient body before winter comes.

General management and protection measures

1. Strengthen the management of fertilizer and water

Apply phosphorus and potassium fertilizer to flowers that are dormant in winter. Flowers that are not dormant in winter can still apply nitrogen fertilizer, especially foliage plants should still apply nitrogen fertilizer. However, attention should be paid to the combination of phosphorus and potassium fertilizer. Reasonable application of phosphorus and potassium fertilizer can improve the cold resistance of flowers. Plants that bloom in winter, such as Chrysanthemum morifolium, Prunus bungeanum, cyclamen, poinsettia and Lamei, are vegetative growth periods in early autumn, and fertilizers based on nitrogen fertilizer should be applied in early autumn. When fertilizing such flowers, phosphorus and potassium fertilizer should be given priority to and nitrogen fertilizer should be used as a supplement. Too much nitrogen fertilizer is not conducive to flowering in winter. For flowers and seedlings planted in the open field, the soil is generally neither dry nor watered, but watered thoroughly. Potted flowers should pay attention to frequent watering, watering thoroughly, should not be watered half of the water, the formation of wet and dry, affecting root growth; should also prevent excessive watering, causing rotting roots. After entering autumn, the supply of water should be controlled to promote the maturity of new shoots, so as to prevent flower seedlings from drawing new shoots in late autumn and winter, which is not conducive to overwintering. However, in early autumn or Mid-Autumn Festival, due to the high temperature, flower seedlings produce new shoots, during this period, there should be sufficient water supply to ensure that the new shoots can grow and mature in time. The watering time should be in the morning and afternoon in autumn. Its purpose is to make the water temperature close to the soil temperature, which is conducive to absorption and avoid damage to the root system.

two。 Pay attention to the regulation of florescence

Many flowers are arranged to bloom during New Year's Day and Spring Festival, so they should be cultivated or restrained. If the full sky is a long sunny flower, if it is required to blossom in winter, it must begin to supplement light in early September, generally increasing illumination for 4 hours from 10:00 to 2:00 in the evening for one month in a row. Chrysanthemum is a short-day flower, which must be brightened in order to delay its flowering. The supplementary light also starts from the first and middle of September to the expected 50 days before flowering. For some warm-loving flowers, such as Anthurium andraeanum, Phalaenopsis, etc., it should be heated when the daily average temperature is lower than 15 ℃. Lily cultivation in autumn and winter should not only be heated at low temperature, but also need light to prevent hidden buds.

3. Strengthen the control of diseases and insect pests

The main pests in autumn are: carnation, all over the sky against cabbage insects, African chrysanthemum against leaf mites, chrysanthemums against cabbage green insects, aphids, lilies against aphids and so on. The main diseases: chrysanthemum spot, rose black spot, powdery mildew, carnation leaf spot, African chrysanthemum spot, etc., the disease should be mainly prevented, pay attention to ventilation, reduce the air humidity in the greenhouse, increase the application of phosphorus and potassium fertilizer, and improve plant disease resistance. spray protection and control.

4. Intermediate ploughing and weeding

Mid-tillage can loosen topsoil, reduce water evaporation, increase soil moisture, promote air circulation and nutrient decomposition in soil, and create good conditions for root growth and nutrient absorption of flowers. Weeding can prevent weeds and flowers from competing for soil nutrients, moisture and sunlight. Intertillage can weed at the same time, but weeding is not a substitute for intertillage. The depth of intertillage is generally 3 to 5 cm. At the same time, mid-tillage weeding can also help to prevent diseases and insect pests and reduce the incidence of diseases and insect pests in the coming year.

5. Shaping and pruning

Autumn shaping and pruning should be based on "light", so as to avoid causing tree weakness and even dead seedlings caused by "heavy". The main pruning methods are heart-picking, pruning and so on. Based on the natural shape of the plant, plastic surgery is carried out according to the needs. Among them, trees are mainly pruning, highlighting the trunk to ensure that the trunk reaches a certain height before it branches; shrubs mainly through coring to maintain its original shape or promote it to form an ideal shape to expand its crown width. The quality of flowers can be improved by shaping and pruning.

Management of planting flowers in courtyard

1. Transplant

For the layout of the new courtyard or the transformation of the old courtyard, the flowers planted on the ground can also be transplanted on the premise of having a good soil ball. Transplanting should carry out intensity pruning and strengthen watering and shading management in order to ensure that transplanting is foolproof.

two。 Pruning and heart-picking

Continue to prune the vigorous and budding courtyard hedges and ball ornamental plants, which is also the last pruning of courtyard hedges and ball plants in the growing season in the northern region in autumn. The main garden hedges and color plants suitable for pruning are: boxwood, French holly, spinulosa Photinia, privet, lobular privet, red leaf Berberis, gold leaf privet, Phnom Penh Platycladus orientalis and so on. Suitable for pruning ball ornamental plants are: Dragon cypress, Shu juniper, red bayberry, wolfberry, holly, heather, Haitong, firethorn, Admiralty and so on. Can be planted on the ground to pick the heart are: a string of red, thousand red, sulfur chrysanthemum, ground skin, marigold, peacock grass and so on. It is appropriate to pick the heart every 10 days to promote it to form a plump plant shape, and give birth to more inflorescences on the lateral shoots, and stop picking the heart after late September.

3. Seed collection

The woody ornamental plants that can be collected are mainly flowers and trees of Magnoliaceae. The seeds of Magnoliaceae, yew, seven-leaf tree, begonia, etc., must be stored in wet sand until early spring next year, and then sow in the field after the seed crack. The seeds of grass flowers that can be harvested are: marigold, zinnia, impatiens, purple jasmine, cockscomb, Catharanthus roseus, wheat straw chrysanthemum, emerald chrysanthemum and so on.

Management of garden potted flowers

1. Pruning

For potted chrysanthemums, it is necessary to continue to peel buds and remove buds; to prune rose, pomegranate, Milan, jasmine, pearl orchid, triangular plum, five-colored plum, golden bract, coral flower, etc., after each flowering; for those tree stump bonsai species that are resistant to pruning, easy germination and exuberant growth, continue to prune or pick buds.

two。 Pest control

The number of diseases and insect pests of flowers in autumn is less than that in summer, so the management of diseases and insect pests should give priority to prevention. The red-necked longicorn beetles on potted plum blossom, begonia, Birthday Bun with Bean Paste Filling, green peach and other plants can be injected with poison and can also be controlled by burying carbofuran granules. The Japanese tortoise wax scale, cotton blowing scale, shield scale, velvet scale and so on appeared on potted flowers and trees were controlled with 1500 times liquid of 40% speed culling.
