In winter, hydroponic plants include evergreen, palm bamboo, peach leaf coral, spider egg, gem flower, etc. Evergreen and palm bamboo do not wither and turn yellow in winter, and peach leaf corals and plant eggs are also very hardy. Breeding evergreen, in terms of watering, it needs to be watered every two days in spring and autumn, once a day in summer, and once every half a month in winter.

Hydroponic plants in winter include evergreen, palm bamboo, peach leaf coral, spider egg, gem flower, etc. These hydroponic plants have strong cold tolerance to ensure that they can survive the winter. Evergreen and palm bamboo will not wither and turn yellow in winter, and are still lush and full of vitality.

Peach leaf corals and spider eggs are also very cold-tolerant, and can withstand low temperatures of 0 at a minimum. Although it is not very cold-tolerant, it will go into a dormant state when the temperature is too low, allowing it to survive the winter safely.

In addition to hydroponics, evergreen can also be soil-cultured. Soil cultivation is evergreen, and it is necessary to choose loose and fertile, slightly alkaline sandy loam soil with good drainage and air permeability. Evergreen has a high demand for light, but is afraid of strong light, so it needs to be placed in a semi-shaded place to receive scattered light maintenance.

Evergreen doesn't need much water, but it still needs to have plenty of water. It needs to be watered every two days in spring and autumn, once a day in summer, and once every half a month in winter. This can ensure that evergreen has sufficient water, and can also avoid water accumulation in the root system, which can lead to root rot.

Spider plant hydroponic spider plant is a more common foliage plant so far, its vitality is extremely tenacious, its leaves are evergreen all year round, as long as the water is changed frequently, the appropriate amount of nutrient solution can thrive, it can be placed in a semi-shady environment, direct sunlight may burn the leaves.

Pothos hydroponic pothos is very simple, often change the water, and then add a little nutrient solution in an appropriate amount, put it in a warm and humid environment, if it is dry in winter, you can spray some water around. The leaves of pothos are evergreen all year round, and the branches and stems are naturally drooping, which has high ornamental value, and pothos can effectively purify the indoor air and make the indoor air more fresh.

Fugui bamboo hydroponics Fugui bamboo is also a more common plant, you can grow very well if you need to change the water frequently, but the water in the container should not exceed two-thirds, shade tolerant, can be placed indoors for a long time. Fugui bamboo is a foliage plant, its leaves are evergreen in all seasons, thick green, the stem is straight, and it means that the flowers are rich and the bamboo is safe, so it is deeply loved by everyone.

Hyacinth hyacinth hydroponics needs to be cultivated with a special vase, and it needs to change the water for its stem length during hydroponics, and add an appropriate amount of nutrient solution, it can grow very well. When hyacinth is just hydroponic, it resembles a white onion, with green leaves growing on it, and the flowers are beautiful and showy, accompanied by a faint floral fragrance.

Gerbera gerbera chrysanthemum hydroponics do not immerse the leaves in water, often change the water to increase oxygen, if you find rotten roots or rotten leaves when changing the water, cut them off, add a little nutrient solution in an appropriate amount, and place it in the place where the light is scattered. Gerbera has a wide variety of flower colors, and often blooms in all seasons, with high ornamentality, and gerbera can effectively absorb indoor formaldehyde.

Hydroponics include pothos, narcissus, green leaf jasper, fortune bamboo and other bamboos, fortune tree leaves, and desmodium.

Winter is not the peak season for plant growth, and the nutrient solution for hydroponic plants naturally needs to be reduced, and it should be used appropriately and appropriately, and the nutrient solution can be supplemented once every half a month in winter. In winter, it is not recommended to replace soil-grown plants with hydroponics, which can be carried out after the spring is warm. You don't need to pour out all the water in winter, because the plant root system grows well, if all the water is replaced, it is equivalent to a new environment for the plant, you can retain 1 3 of the amount of water, and the appropriate water change can make the plant recover faster.

The leaves of hydroponic plants should not be soaked in water, and even the rhizomes should not be soaked in water, only the roots should be fully exposed to water.

Cold-tolerant four-season evergreen aquatic plants have calamus, reed bamboo, shallot, dry umbrella, sand cane and other plants, calamus is a perennial herb, the flowering period of calamus is in June to September every year, the flower fragrance is very strong after flowering, so it is commonly used to extract aromatic oil, reed bamboo stalk is thick and erect, the leaves are flattened, and the leaf edges are slightly rough.

1. Calamus

Cold-tolerant evergreen aquatic plants include calamus, calamus is also called white calamus, its flowering period is in June to September every year, the flower color is yellow or white after flowering, and there is a strong floral fragrance, so it is often used to extract aromatic oil.

2. Reed bamboo

Cold-tolerant evergreen aquatic plants in all seasons include reeds. When cultivating reed bamboo, it is necessary to provide light for it, and the plant can be placed in a sunny place to allow the reed bamboo to photosynthesize and promote the growth of the plant.

3. Shallots

Cold-tolerant evergreen aquatic plants have shallots, shallots in the process of growth, the demand for water is larger, need to water the plant every 3-5 days to meet its growth needs, to avoid the lack of water in shallots.

4. Dry umbrella

Cold-tolerant evergreen aquatic plants have umbrellas, when breeding umbrellas, you can use sharp scissors to cut off the withered, poorly grown, yellowing leaves of the plants, reduce the consumption of nutrients by umbrellas, and after pruning, you need to apply disinfectant to the wounds of the plants to avoid infection of bacteria in the wounds.

Shade-tolerant hydroponic plants include pothos, white palm, water peanut, ragweed, purple stem Zeland, airplane grass, rice grass, Migan, monstera, dripping Guanyin, etc.

Shade-tolerant plants are those that grow better in a place with good light conditions, but can also tolerate proper shade. There is also the need for a lighter shade plant during the growth period, which requires between 1 15 and 1 10 of the light required by a sun-loving plant.

1. "Dress and keep warm" put on protective clothing for plants.

Do a good job in the anti-freezing and warmth of the public green space in the central city and the green space in the park square, do a good job of whitening the seedlings, and carry out measures such as "wrapping and dressing" and spraying antifreeze for non-cold-tolerant plants, such as triangular plum, frangipani, and olive seed, to ensure the smooth wintering of green plants.

2. "Haircut and pruning" to reduce the weight of plants.

Make every effort to do a good job in the investigation work, in the pruning process, according to the winter plant growth characteristics and climate characteristics of the relevant plants to prune, in order to reduce the winter frost load, to ensure the overwintering ability of plants.

3. "Hydration and humidification" to "drink full water" for plants

Continue to do a good job in watering and irrigation, because the city is located in the south, the climate is relatively warm, and the precipitation in winter is significantly reduced, in order to ensure the smooth wintering of green space plants in the public green space and park square in the central city, the greening and maintenance enterprises are required to take their own responsibilities, increase watering and irrigation, avoid low temperature periods, and ensure that watering is in place.

4. Scientifically plant hard-resistant tree species.

Implement the principle of suitable trees in the right place, fully understand the biological and ecological characteristics of transplanted trees, distribution areas and extreme temperature conditions of transplantation sites, and introduce large trees that are not subject to frost damage under the local extreme temperature according to local conditions. In places with better climates, marginal tree species can also be planted, which can greatly reduce the workload of wintering and cold protection.

5. Strengthen cultivation management and improve the cold resistance of trees.

Strengthening cultivation management, especially in the later stage of growth, is conducive to the accumulation of nutrients in the tree. Heavy application of basal fertilizer in autumn is an important measure to improve the frost resistance of trees, restore tree vigor and improve soil structure.

6. Artificial cold-proof measures.

In late autumn and early winter, it is necessary to take warm measures to strengthen tree protection and reduce frost damage. Specific artificial cold-proof measures include whitening of tree trunks, the use of antifreeze, irrigation of antifreeze water, root neck soil, erection of wind barriers, and rolling.
