How to raise dry lotus in summer, how to grow stout / cooling and shading

In the cultivation method of Clematis paniculata, because of its fear of high temperature, it must pay attention to the changes of temperature and humidity in summer, otherwise it is easy to produce yellow leaves, plant wilt and even death, so how to raise it in summer? How does the dry lotus grow stout? Come to summer maintenance skills together.

How to raise Golden Lotus in Summer

1. Appropriate cooling

Golden lotus has a growth habit, that is, the growth and flowering will be blocked when the temperature is higher than 35 degrees, which will affect the whole process of development, so we must pay attention to the temperature change in summer and take cooling measures when the temperature is higher than 30 degrees Celsius. For example, move it to a cool place, or spray water on the leaves.

2. Shading and avoiding light

Although dry golden lotus likes plenty of light very much, the sun is relatively strong in summer, so it is not suitable to put it in the sun, otherwise it will be yellowed because the leaves are burned and the UI we often see, so it is generally necessary to shade in summer, and it is best to put it in a semi-shaded environment.

3. Stop fertilization

During the growing period, it is necessary to apply thin fertilizer and water every half a month, but in terms of fertilization, how to raise the lotus in summer? The answer is to stop fertilizing, because at this time the growth of Clematis is relatively slow, for the fertilizer requirements of it is not high, if fertilization will have the opposite effect.

4. Rational watering

Because of the high water demand in summer, it is usually necessary to water the lotus once a day. If it is still dry, you can spray some water on the leaves in the evening, which can not only reduce the temperature, but also increase the air humidity. It is beneficial to keep the leaves green.

5. Environmental ventilation

When moving the dry lotus to the semi-shady environment, we must pay attention to the well-ventilated environment, otherwise it is easy to appear too muggy and closed, which will lead to premature withering of branches, and may also cause diseases and insect pests such as red spiders.

How does the dry lotus grow stout?

1. Styling pruning

The growth of Clematis is relatively rapid, and it has the characteristics of semi-trailing flowers, it is easy to have luxuriant branches and leaves, and it may also have a sloping or creeping growth, which affects its beauty, while pruning can not only maintain its beauty, but also make its nutrients more concentrated and make it grow more healthily.

2. Solution spraying

When the stem grows to 30-40 cm, the leaves can be sprayed with paclobutrazol solution, which can dwarf the plant, thus thickening the main vine, achieving the effect of thicker plants, and more importantly, flower friends grow indoors.

Tissue Culture and Rapid Propagation of Clematis paniculata

Nelumbo nucifera is a perennial semi-trailing or recumbent plant of the family Nelumbo nucifera. Plant height 30cm-70cm. Basal leaves long stipitate, leaf blade pentagonal, triplicate, bifid with a few lobules and acute teeth. Flowers solitary or 2-3 in Cymes, petals 5, sepals 8-19, yellow, elliptic-Obovate or Obovate, petals as long as sepals, narrowly striate.

In the north, flowers are often cultivated in 2012. Under suitable environmental conditions, it can blossom throughout the year. A flower can last 8 Mel for 9 days, and the whole plant can produce dozens of flowers at the same time, which has won the love of people because of its fragrance and bright color.

Characteristics and habit botanical characteristics Tropaeolummajus, also known as Golden Lotus, dry Lotus, etc., is an annual or perennial herbaceous vine flower of the genus Trollius of the family Trollius, which is used to be cultivated annually. The leaves are round and shield-shaped, with wavy obtuse angles, alternate, long stalked, leaves like lotus leaves, smaller leaves, about l0cm in diameter, dark green or light green in color, grayish in green, and obvious veins. There is leathery wax powder on the leaf surface, which condenses and rolls bright dew beads like pearls after rain or when the morning dew is not dry. The flowers are axillary, numerous in number, with a long florescence and bloom almost all the year round. The petals are 5-parted and the flowers are trumpet-shaped. The colors are purple, orange, creamy yellow and so on. There is a velvet light on the flower surface. The stem of the seedling was erect, the seedling was generally high in 25~30cm, and the stem was creeping like a vine in the middle and later stage. Biological habits are native to the humid areas of Peru and Chile in South America. They like to be born in warm, humid and sunny environments. They are not resistant to cold, fear long-term waterlogging, fear high temperature and heat, and are suitable to grow in an environment of 10 ℃ ~ 25 ℃. The best growth and flowering temperature is 18 ℃ ~ 24 ℃, long-term lower than 10 ℃ or long-term higher than 30 ℃ are not easy to bloom or do not blossom. Leaves are prone to disease when long-term higher than 35 ℃. It will wither if it is lower than 3 ℃ for a long time, and it can generally withstand low temperature below 0 ℃. The requirement of soil quality is not strict, the acidic soil in the south and the alkaline soil in the north can grow, and the fertile and loose sandy soil is better. The conventional culture methods of Clematis paniculata are mainly sowing and cutting culture. Sowing and breeding generally sow at the end of August or early September and blossom from November to April to May of the following year, but the seed germination rate is low, so it is difficult to develop in a large area. Cuttage culture is generally in the high temperature season, the survival rate is low, and the seedling growth is weak after cuttage survival. The single plant with good growth, color and beautiful flower shape can be cultured rapidly by the method of tissue culture, and a large number of high quality seedlings can be cultured in a short time without the restriction of time and season. Tissue culture and rapid propagation showed that the material had tender lateral buds with 3 or 4 leaves. Culture condition induction medium: (1) MS+BA0.5mg/L + IAA0.1; (2) MS+BA0.5+IAA0.2; (3) MS+BA1.0+ IAA0.1; (4) MS+BA1.0+IAA0.2; (5) MS+BA2.0+IAA0.2; (6) 3/2MS+BA0.5. Proliferation medium: (7) MS+BA0.5+IAA0.1; (8) MS+BA1.0+IAA0.1; (9) MS+BA0.5+IAA0.2; (10) MS+BA0.5+ GA0.2; (11) MS+BA0.5+NAA0.1+GA0.5; (12) MS+BA1.0+NAA0.1+GA0.2; (13) MS+BA1.0+ GA0.5; rooting medium: (14) 1/2MS+NAA0.2. The Agar content of the above culture medium was 5.5g/L, sucrose 30g/L, pH 5.8. The culture temperature is 20 ℃ ~ 24 ℃ and the light is 3000lux22 13 hours per day. Growth and differentiation (1) acquisition of aseptic materials: in the peak growing season, that is, from November to April of the following year, the well-growing potted mother plant was selected, the lateral buds that germinated for 7 days and 10 days were cut, the leaves and petioles were removed, and directly into the ultra-clean worktable. Rinse the sterile bottle with aseptic water for 10 minutes, remove it and disinfect the surface with 70% alcohol for 10 seconds, then disinfect the surface with 0.1% mercury for 5 minutes. Or 2% sodium hypochlorite disinfection for 7 minutes, rinse with sterile water for 4 times, cut off the discolored part of the wound damaged by fungicides, remove the larger young leaves visible to the naked eye, cut them into 2~5mm size, cut the rest into single bud stem segments, and inoculate on medium (1) to (6) respectively. The terminal buds germinated after 7 days, and the lateral buds began to germinate after 2 weeks. Among them, medium (1) and (2) are suitable for the germination and elongation of terminal buds and lateral buds. After 2 weeks of culture, the apical bud extended to 4cm and spread out 4-5 leaves (see figure 1). When the explants inoculated on (5) and (6) media, the germinated terminal buds and lateral buds were yellowed, thick and short, which was not suitable for the induction and culture of terminal buds and lateral buds. (2) subculture: the differentiated buds were cut off and inoculated on the medium (7) to (13). After about 3 weeks, the buds inoculated on the medium (8) formed 3-4 lateral branches, the height of the plant could reach more than 6~7cm, and the multiplication multiple could reach 8-10 times. Continue to cut into single bud stem segments and inoculate on medium (8) for subculture, every 3 weeks is a subculture cycle, a large number of test-tube plantlets can be obtained in a short time. (3) rooting culture: the buds with high 3~4cm were inoculated on the medium (14), and the roots began to take root after one week. After 10 days of culture, the rooting rate reached 100%. The roots were white and stout, and each plant had more than 10 roots. The root system is very developed, mainly attached to the surface of the culture medium, on which there are a large number of white root hairs. (4) domestication and transplanting: transplant the rooting seedlings in the greenhouse for 3 days, open the bottle mouth, pour water and shake, carefully remove the test tube seedlings, wash the Agar attached to the roots, soak with 600x liquid carbendazim, transplant to the peat ∶ perlite ∶ vermiculite = 3 ∶ 1 ∶ 2 mixed medium, spray with 600x liquid carbendazim, cover with film to protect moisture and shade, gradually uncover the film and ventilate after 5 days, the survival rate can reach more than 96%. Cultivation and management after transplanting, the test-tube plantlets were replanted into 18~20cm diameter flowerpots as soon as possible, 1 in each pot. Row spacing 80cm, plant spacing 50cm in flower bed or field cultivation, and water thoroughly after planting seedlings. The fertilizer and water should be increased properly during the seedling period, and the rarefied all-element compound fertilizer and water should be sprayed every 15 days. During the seedling period, less fertilizer and water should be applied to prevent overgrowth. The test-tube plantlets can blossom after being transplanted into flowerpots or flower beds for about 1.5 years and 2 months (see figures 5 and 6). The maintenance of Golden Lotus in winter and spring should increase the temperature and light; in summer and autumn, 70% shading net should be used for shading and cooling, and the shading net should also have the function of shading rain to prevent rainstorm from hitting leaves and flowers. When drought and high temperature should be sprayed or watered to cool down, dry and thorough pouring, quick pouring and quick drainage should be achieved, and attention should be paid to the root without stagnant water. It is forbidden to splash leaves and buds with mud and fertilizer when watering and fertilizing. According to its biological characteristics, it can blossom normally only when it is kept above 10 ℃ ~ 15 ℃ and under 30 ℃, and avoid cold, high temperature and hot sun exposure. In order to promote multi-flowering, when the seedlings grow to 3-4 true leaves, they should be coring and promoting multiple lateral branches. in addition to leaving the main branches and sturdy lateral branches before putting on the shelf, it is also necessary to pick the heart, insert the stem and tie the stem evenly on the rack and tie it into various decorative forms. In the later stage of growth, the stem can also be cut off to give birth to new buds, and the new stem can be reissued and flowered after careful maintenance for about a month. Fertilizing with nitrogen, phosphorus, potassium and other multi-element fertilizers, 1/2MS nutrient solution or mature livestock manure can be applied far away from the roots and burying holes. A small amount should be applied many times. After Frosts Descent, the potted Clematis should be moved indoors and placed in the windowsill or in a sunny place. The temperature should be kept at 10 ℃ ~ 15 ℃, and the lowest temperature should not be lower than 8 ℃. The stem of Nelumbo nucifera is sprawling, it is generally necessary to set up a support, if it is allowed to grow naturally, the stem is bound to be too long, affecting the ornamental. In order to control the unlimited growth of its stem, when the stem growth reached 30~40cm when it entered the early flowering stage, it was sprayed with paclobutrazol solution of 100ppm to promote its dwarfing. It can be effective three days after spraying, the main vine thickens, the top vine lengthens slowly, and the flowers on the side vines bloom one after another, quite beautiful. Pest control is generally not easy to be harmed by diseases and insect pests, but in summer and autumn high temperature and rainy season, leaves are prone to powdery mildew, leaf spot, wilt and virus diseases, which can be eliminated or reduced by strengthening ventilation and dehumidification. In severe cases, the foliar surface was sprayed with 500-1000-fold methyl topiramate or 500-fold strychnine, 2 times every 7 days. It will also be damaged by whitefly at the end of autumn and the beginning of winter. You can spray the leaves with 1000 times of trimethoprim. Technical characteristics and habit botanical characteristics of tissue culture and rapid propagation of trollius (Tropaeolummajus), also known as Trollius, dry lotus, etc., is an annual or perennial herbaceous trailing flower of the Trollius family. The leaves are round and shield-shaped, with wavy obtuse angles, alternate, long stalked, leaves like lotus leaves, smaller leaves, about l0cm in diameter, dark green or light green in color, grayish in green, and obvious veins.
