Sowing method and domestication Seedling technique of Acer Leaf Clematis

How to sow and raise seedlings of clematis maple leaves? Acer leaf clematis is a unique resource in China and belongs to Clematis family. The introduction and cultivation of Acer leaf clematis is recognized as a difficult problem in China. Domestication of this variety is of great significance for vertical greening, such as three-dimensional greening, hanging greening, wall greening and so on. Here are the introduction and domestication techniques of Acer Leaf Clematis, for reference only!

(1) Collection of seeds and branches

In May 2013 and May 2014, we went to Miaofeng Mountain in Beijing to collect seeds and branches of Acer Leaf Clematis, preserved the branches in a fresh-keeping box, preserved the seeds in a seed bag, and transported them to Nanjing, Jiangsu Province.

(2) sowing

The seeds of Clematis maple were sown in a pot containing pure river sand, then covered with 3-5mm thick river sand and watered thoroughly. Irrigate with clear water every 3-7 days. Under the ambient temperature of 15-25 ℃, cotyledons can be seen about 15-20 days after sowing, and enter the daily cultivation management according to step 5 after 30 days.

(3) Cuttage

Cutting: the branches of Acer Leaf Clematis are made into 2-4cm long cuttings, each cuttings contain 2-3 bud points and leave a leaf; fill the flowerpot with river sand: gravel = 1: 1 or the substrate of river sand, and pour through the substrate with 50% carbendazim wettable powder before cutting. Dip the base of the cuttings in 2000 mg/L of IBA solution for 60s, then insert the cuttings into a flowerpot with a depth of 1 × 2 ~ 2 × 3 of the length of the cuttings, with 10 short ears in each pot.

After cutting, use 85% shade net to cover sunscreen, spray water automatically at 9:00-17:00 every day, spray once per 10min in sunny days, 7-12s once per 50min in cloudy days, spray 10s once. Spray it thoroughly with 50% carbendazim wettable powder 800 times turbid liquid every week. After 120 days of cutting, follow step 5 to enter the daily cultivation management.

(4) Management after survival

Acer clematis is a rock flower growing in rock crevices. This unique habitat results in its special growth environment. The PH value of soil near Acer leaf Clematis habitat was 7.2, while that of Rain Water and tap water in Nanjing, Jiangsu Province was slightly acidic (PH value was 6.2). It was found that clematis maple leaves irrigated with clear water grew slowly and their leaves gradually turned yellow, while those irrigated with nutrient solution alone grew slowly. When the combination of alkaline water and nutrient solution (PH 7.2) was selected, the seedlings grew fast as a whole, and there was no yellow leaf phenomenon. For this reason, sodium hydroxide was used to adjust the PH value of the prepared nutrient solution to 7.2. Irrigate with nutrient solution, once every 3-7 days.

Formula of nutrient solution attached:

Planting and maintenance methods of Clematis celery

Clematis celery like to grow in a sunny environment, with good cold and drought tolerance, while the requirements for planting soil is deep and fertile, good drainage, and the soil is preferably alkaline or sandy loam. Because the roots of Clematis celery are not resistant to water stains, it is necessary to avoid stagnant water. If it is a potted culture of celery leaf clematis, the pot needs to be changed once a year. For Clematis celery, spring and autumn is a very exuberant season, and in summer, with the rise of temperature, it is necessary to shade Clematis celery, otherwise it will lead to withered and yellow leaves, poor growth and so on.

[editor's summary] the branches of Clematis celery are very slender and can be up to 2 meters long. As a traditional Chinese medicine, it is usually harvested in summer. The above is the planting and maintenance methods of Clematis celery, I hope it can be helpful to everyone.

Planting methods of Clematis _ planting skills of Clematis

Clematis has become a world-famous ornamental plant because of its outstanding ornamental effect and special garden use, and enjoys the laudatory name of "Liana Queen". The following is the clematis planting method that we have carefully sorted out for you. Let's have a look.

Planting method of clematis

Sowing, striping, grafting, split or cutting culture can be done.

Sowing: the original seed can be cultured by sowing. Seeds of the type unearthed from cotyledons (achene is smaller and the pericarp is thinner) can germinate in 4 weeks if sown in spring. Sow in autumn and germinate when spring is warm. Cotyledon retained soil type seeds (larger, thicker seed coat) can only germinate after a low-temperature vernalization stage, and the first pair of true leaves are born; some species have to go through two low-temperature stages to germinate, such as rotator lotus. For vernalization treatment, if the seeds were refrigerated with 0Mel 3 ℃ for 40 days, it would take about 9-10 months for them to germinate. It can also be treated with a certain concentration of gibberellin.

Crimping: in March, use last year's mature branches to crimp. It usually takes root within a year.

Grafting: a hybrid of clematis that can be split onto C.vitalba or C.viticella rootstock by a single scion. There are 2 buds on the node and 5-10cm under the node. Grafting in a heated and airtight grafting box is easy to promote survival.

Ramet: tufted plant, which can be ramified.

Cutting: cuttage is the main culture method for hybrid clematis. The semi-mature branches were taken from July to August and intercepted in the middle of the internodes (that is, the upper and lower nodes), with 2 buds on the nodes. The medium is made of peat and sand in half. The cutting depth is just above the bud on the node. The base temperature is 15-18 ℃. After rooting, put up a 3-inch basin and spend the winter in an anti-freezing hotbed or greenhouse. Change the 5-inch basin in spring and move it out of the room. Shade and showers are needed in summer and planted at the end of October.

Cultivation of Clematis

Planting time: after thawing in the north, the middle is in April-May. Don't fill it too tightly around the root, just press it a little with your hands. The top of the soil mass of potted plants should be flush with the topsoil, and when planting bare roots, the root cap should be 5 boxes of rice below the surface. After planting, it is covered with 10 cm thick peat or humus to avoid overheating of the roots in summer and to keep the soil moist. The seedlings should be planted at one time. It can be transplanted in spring or autumn. The species of flowers on the old branches, such as clematis and rotors, are only slightly pruned, while those flowering on new shoots or lateral branches, such as hybrid clematis and hairy leaves, can be pruned a little heavier. Select the leeward and sunny places to plant plants with earthen balls.

Note:

Pay attention to adequate water supply in the first few months after planting. The diameter of the water supply range is not less than 50 cm, so that the root can be extended in all directions.

If the branches are brittle and easy to break, attention should be paid to attracting and fixing them.

Special attention should be paid to drainage in the cultivation of clematis.

When planting, the hole is generally 40 cm deep and 60 cm in diameter. After digging the hard soil at the bottom of the hole, put in a large amount of humus, and then add the topsoil mixed with bone powder. In poorly drained clay or light sand, the bottom of the hole should be mixed with peat or humus after loosening. The bottom of the possible stagnant water should be cushioned with stones or rubble, 25 centimeters above the surrounding soil.

Pest control:

Clematis has strong resistance to diseases and insect pests, and serious damage to diseases and insect pests rarely occurs. The disease is caused by Fusarium wilt, which is likely to clear up on rainy days in summer. when the temperature rises sharply, the branches suddenly wither, and new techniques often sprout in autumn or the following spring. Others have powdery mildew (harmful leaves or flowers), virus diseases (yellow spots in leaves, flower deformities), etc., sprayed with 1000 times of acetic acid solution of 10% antibacterial agent. Pests are harmful to red spiders and stinging moths, which are sprayed with 1000 times of 50% fenitrothion EC.

Planting skills of Clematis

One kind of seedling selection

Because the root system of clematis is not competitive enough, it is necessary to choose plants with full roots, multi-stem and strong dark green when selecting seedlings.

2 preparation before planting

Matrix: generally fertile and well-drained substrates can be used to grow clematis. We chose the matrix in which peat and perlite were mixed at the ratio of 3 ∶ 1 or 2 ∶ 1, the EC value of the matrix was controlled at 60-80 mgPkg, and the pH value was between 518-615.

Support: the final size and growth of clematis are related to the support, which should be small (smaller than 115cm in diameter) so that the petiole can be wound. The support can be made of thin bamboo pole or plastic barbed wire, with a height of between 1m and 2m.

Basin: the basin should be at least 35 cm deep and 25 cm wide. Of course, the bigger the better. Pots are best made of wood or pottery, which is not only beautiful, but also conducive to the growth of clematis roots.

3 planting

Cutting the stem of Clematis to a height of 30 cm before planting is beneficial to its branching and can avoid breaking the stem during planting. The stem base of Clematis clematis should be 3'5 cm below the soil surface. After the plant is placed at a suitable depth, cover the soil, compact and water it.

Clematis roots like cool environment. Covering 3-5 cm thick mulch (such as bark, moss, etc.) on the planting substrate can provide a good and cool root environment, which is beneficial to the growth of plant roots.

The planting time is arranged in March to May or September to October.

4 maintenance

Temperature: the optimum temperature for growth is 15: 17 ℃ at night and 21: 25 ℃ at day. In summer, when the temperature is higher than 35 ℃, it will cause clematis leaves yellowing or even falling leaves, so cooling measures should be taken in summer.

In November, the temperature decreases continuously, and when the temperature is below 5 ℃, Clematis will enter the dormant period. In December, Clematis completely enters the dormant period, and in the 1st and 2nd week of dormancy, Clematis begins to fall leaves.

Lighting: clematis requires more than 6 hours of direct light a day, which is very beneficial to its growth, although spots can occur in hot weather. Some red, purple and dark blue large flower hybrids and bicolor varieties need sufficient light to obtain gorgeous flowers, while some small flower varieties can grow and bloom in semi-shade.

Watering: clematis is very sensitive to moisture and can not be too dry or too wet, especially in the summer high temperature period, the matrix can not be too wet. Generally, water is watered every 3-4 days during the growing period, and watering is carried out when the substrate is dry but the plant does not wilt. During the dormant period, as long as you keep the matrix moist. Do not let water accumulate on the leaf surface or at the base of the plant when watering, otherwise it is easy to cause disease.

Fertilization: before sprouting new buds in late February or early March, a little compound fertilizer with a NPK ratio of 15 ∶ 5 ∶ 5 could be applied to accelerate growth, and once phosphate fertilizer should be applied in April or June to promote flowering. The water-soluble fertilizer of 20 ∶ 20 ∶ 20 or 20 ∶ 10 ∶ 20 of 150 mgPkg is usually used, which is increased to 200 mgPkg in the peak growth period and sprayed 2 times 3 times a month.

Pruning: the purpose of pruning is to plant more flowers. Pruning is usually done once a year to remove some overdense or thin branches so that the new branches can be extended in all directions. The time of pruning should be determined according to the flowering period of different varieties: early flowering varieties (florescence 4-5 months) should be pruned after flowering, that is, June-July, to remove excess branches, but the Lignified branches should not be cut off. if pruning before then, it will lead to the failure of flowering in the same year. The dead or thin branches of the large flower hybrid variety (flowering period May-June) were removed in February-March, and the large plump buds were retained at the top of the branch, while the late-flowering variety (florescence June-October) was pruned to 60-90 cm high in February-March, which required the removal of some good branches.

5 reproduction

Clematis are often propagated by cuttings or strips. The semi-lignified stem segment with full bud was selected for cutting, and a leaf was left. After soaking in rooting solution for 7 days, the cuttings were inserted into the medium mixed with 2 parts of sand and 1 part of peat, providing more than 80% humidity, 18 ℃ and 5 000 lx light, and rooting in 4 weeks. Some large flower hybrid varieties take longer, and if they are cut in May, they may take root in late August. If it has taken root in early August, it can be planted. If it does not take root until late August, it will be planted in the early spring of the following year. Striping is a relatively easy method, which can also be carried out in autumn, using nodes on current or annual branches embedded in the substrate of sand ∶ peat = 1 ∶ 1, rooting can take root within 12 months, and the rooting part can be separated and planted.

6 diseases and insect pests

Fusarium wilt is the most important disease of clematis, which can occur suddenly and shrink the whole plant, although the plant still has good roots. Spraying carbendazim or topiramate once every 2 weeks and repeating 2-3 times can effectively inhibit the occurrence of the disease. Powdery mildew is another disease harmful to Clematis clematis. It is easy to occur when the temperature is more than 20 ℃ and high humidity. Carbendazim and methyl topiramate can be used alternately every other week for 3 or 4 times.

The main pests harmful to clematis are aphids, whitefly, red spider, thrips, scale insects, which can be controlled by dichlorvos, Kangfudo, propargite, lice, quick culling and other drugs.
