What is the culture method of cold spray?

The leaf pattern of cold water flower is beautiful, like snow falling, it is a kind of foliage plant that is easy to breed, so many flower friends will breed it indoors. Next, I will tell you what is cold spray, as well as cold spray culture methods.

A brief introduction to the cold water

PileanotataC.H.Wright is a perennial herb, stoloniferous. Stem fleshy, slender, middle slightly inflated, petiole slender, often glabrous, rare pubescent; stipules large, greenish. Flowers dioecious, tepals greenish yellow, anthers white or pinkish, filaments and anthers red. Achenes small, ovoid, green-brown when ripe. The florescence is from June to September and the fruiting period is from September to November.

It is distributed in Guangxi and Guangdong, China, through the provinces of the middle and lower reaches of the Yangtze River Basin, north to southern Shaanxi and southern Henan, and distributed in Vietnam and Japan. Born in valleys, streams or under forests, 300-1500 m above sea level. Cold water flower is a very fashionable small foliage plant. The whole herbal medicine has the effect of clearing heat and dampness, promoting fluid and relieving thirst, relieving jaundice and protecting the liver.

Morphological characteristics of cold water flower

Herbs perennial, stolon. Stem fleshy, slender, middle slightly inflated, 25-70 cm high, 2-4 mm thick, glabrous, sparsely pubescent distally, densely striped stalactites. Leaves papery, subequal in pair, narrowly ovate, ovate-lanceolate or ovate, 4-11 cm long and 1.5-4.5 cm wide, apex caudate-acuminate or acuminate, base rounded, sparsely cuneate, margin shallowly serrated from lower to apex, rare double serrate, dark green above, shiny above, light green below, stalactite strip, 0.5-0.6 mm long, densely distributed on both sides, obvious, 3 basal veins The two arcs on its side extend to the upper part and form a ring with the lateral veins, and the lateral veins are 8-13 pairs, slightly oblique and reticulate. Petiole slender, 17 cm long, often glabrous, rare pubescent; stipules large, greenish, oblong, 8-12 mm long, deciduous.

Flowers dioecious; male inflorescences racemose, 2-5 cm long, with a few branches, Cymes sparsely on flower branches; female Cymes short and dense. Male flowers pedicellate or subsessile, ca. 1 mm at bud; tepals green-yellow, 4-parted, ovate-oblong, apex acute, outside with short horns near apex; stamens 4, anthers white or pinkish, filaments and connective red; pistillode small, conical.

Achenes small, ovoid-ovate, apical oblique, nearly 0.8 mm long, green-brown when ripe, with conspicuous spinelike verrucous protuberances; persistent tepals 3-parted, equal, ovate-oblong, apex obtuse, ca. 1 max. 3 as long as fruit.

In the few specimens of this species from Zhejiang, Fujian and Sichuan, China, the edges of the leaves are more or less doubly serrated, and in the eastern and southern parts of Sichuan, there are short hairs on the stems, petioles and dorsal veins of leaves, which is a morphological modification of this species.

Cold water spray culture method

1. Layout

Cold water flower leaf pattern is beautiful, plant-type mother-in-law, more shade-resistant, is a better balcony layout plant. It can be arranged on the tea table and flower rack with scattered light for a long time, it can also be configured with other plants, or hang in the corner of the wall or conspicuous place as a hanging basin.

two。 Change the basin

The basin should be changed when the temperature is about 10 ℃ in spring, and the basin soil should be rich in humus, loose and fertile loam. The plants should be pruned properly before changing pots, and the pots with poor plant types can be re-cut. Keep the basin soil moist, should not be too wet, otherwise the root is perishable, the air humidity requirement is higher, the leaf color is bright green and the pattern is beautiful under the higher air humidity. Water spray should be often sprayed around it to increase air humidity. You can start fertilizing after seeing the new leaves come out. Rotten organic fertilizer should not be used too much urea, such as nitrogen fertilizer is easy to grow crazy, which is not conducive to the appearance of the plant. When the phosphorus and potassium fertilizer is insufficient, the markings on the leaves are easy to fade.

3. Light

Cold spray is a kind of indoor flower with beautiful leaf color, which is very shade-resistant, but prefers sufficient light and should avoid direct light. Flowerpots are placed in the north window in summer and in the south window in winter. If the light is too dark, the color of the leaves will fade; if the sun is too strong, the leaves will be burned.

4. Fertilizer and water

Master the principle of wetting management, keep the basin soil dry and uncracked, moist but not wet. In summer, often spray water on the leaves to keep them clean and shiny. Keep the basin soil moist and do not apply fertilizer when the temperature is high. Spray less water on the leaves in winter, otherwise the leaves will appear black spots, or even black and rotten. Watering 28% or 37% liquid nitrogen fertilizer at a time in about two weeks during the growing period makes the plant strong. After autumn, increase the application of phosphorus and potassium fertilizer to strengthen the stem and prevent lodging.

5. Pruning

The cold water flower is resistant to pruning, and the cuttings can be removed once after the cuttings are put on the pot, and when the new lateral branches grow to 4 leaves, two leaves are left to pick the heart, so repeatedly, a multi-branch plump hemispherical plant shape can be formed. When the old plant grows too tall, it can leave the base 2-3 nodes when changing pots in spring, re-cut it short, pick the heart 2-3 times after sending new branches, and form a short and compact plant shape.

6. Pest control

The harm of common leaf spot disease can be prevented by spraying 200 times Bordeaux liquid. The basin soil is too wet, which is easy to produce root rot, so it can be irrigated with 1000 times solution of topiramate. When root nodule nematodes are found, 3% carbofuran can be applied to control. It is harmful to scale insects and is sprayed with 1000 times of omethoate. If the beetle bites the leaves, it can be killed manually or sprayed with 1000 times the liquid of trichlorfon.

The above is for you to introduce the relevant knowledge about cold water, I hope it can help you, more household knowledge, please pay attention.

How to breed cold water? Introduction to the culture methods and matters needing attention of cold water flower is a perennial herb with strong adaptability and easy to raise, so it is a very popular small foliage plant. Cold water flowers in summer and autumn in the yellow and white flowers, elegant and elegant, the whole plant is fresh, lovely and delicate. Cold water display in the study, bedroom, elegant and pleasant; hanging in front of the window, green leaves hanging, charming and lovely. This article focuses on introducing the maintenance methods of cold splash for the majority of flower friends' reference and learning. Maintenance points 1, light management cold spray is a kind of indoor flowers with beautiful leaf color, very shady, but prefer sufficient light, and should avoid direct light. Flowerpots are placed in the north window in summer and in the south window in winter. If the light is too dark, the color of the leaves will fade; if the sun is too strong, the leaves will be burned. Second, temperature management cold hydration is more cold-resistant, winter room temperature not less than 6 ℃ will not be frozen, more than 14 ℃ began to grow. Third, fertilizer and water management to master the principles of wetting management, basin soil to keep dry but not crack, moist but not wet is better. In summer, often spray water on the leaves to keep them clean and shiny. Spray less water on the leaves in winter, otherwise the leaves will appear black spots, or even black and rotten. Watering 28% or 37% liquid nitrogen fertilizer at a time in about two weeks during the growing period makes the plant strong. After autumn, increase the application of phosphorus and potassium fertilizer to strengthen the stem and prevent lodging. Fourth, propagation method cold water spray propagation multi-purpose cutting method, spring and autumn can be carried out. When the number of families is less, the top of the stem is used as cuttings in May, and the medium is river sand or vermiculite. Under the suitable temperature (20 ℃ to 25 ℃), rooting takes place in about 10 days. When the new bud lengthens from 3 cm to 5 cm, put it on the basin with sandy soil. Pour enough water to fix the root and transfer to normal management. Fifth, the soil cold spray is not strict on the soil, can withstand weak alkali, is more resistant to water and moisture, and is not resistant to drought. Sixth, pruning in order to enhance the pot ornamental effect of cold spray, the growing period should be pruned regularly to promote its branching and maintain full plant shape. If you want to dwarf the cold splash plant, you can prune it properly or pick the heart for 2-3 times. Be careful not to prune too much, otherwise it will easily lead to many and small cold splash leaves, affecting the aesthetics. 7. Change the basin once a year for pest control. When the shape of the old plant is scattered and the ornamental value decreases, the regeneration of seedlings by cutting can improve the ornamental value. At the same time, it can also reduce the harm of diseases and insect pests. In the case of poor ventilation, it is vulnerable to aphids. When the basin soil is muddy for a long time, the roots often rot, so we should pay attention to reasonable control of soil and water. Conclusion: the above is about how to maintain the cold splash. I hope it will be helpful to everyone.
