How to cultivate cold water flower culture methods and matters needing attention

Cold water must be no stranger to many people. At present, it is distributed in many parts of our country. It is liked by people because of its high ornamental and practicality, and it is a kind of plant very suitable for domestic cultivation. There are many ways to cultivate cold water spray, such as hydroponics and soil culture. what I want to introduce to you today is its hydroponics technology.

How to cultivate flowers in cold water by hydroponics

1. The cold water flower likes the humid semi-shade environment, and the most suitable temperature for its growth is about 18-22 ℃. Spray water frequently during the growing period to ensure the wettability of the leaves.

2, should pay attention to avoid strong light directly, had better put it in the place that has bright scattered light to breed, summer should carry on shading to maintain appropriately, but also cannot put in completely dark place, this can make the leaf color of cold splash dim, the branch grows excessively.

3. The bud core should be removed in time after the seedling survives, which can make the overall shape of the plant more plump. Pay attention to regular pruning, reduce plant softness and lodging, promote branches, and make the appearance more luxuriant and beautiful, but not too trimmed, otherwise it will cause many and small leaves of cold water, reducing its ornamental value.

Hydroponic culture method of cold water flower

1. Cold splash is generally propagated by cutting, either in spring or autumn. You only need to cut off a section of branches with top buds and put them directly into the water for cultivation. It takes about ten days to grow new roots, and the survival rate is very high.

2. The roots of potted plants can also be washed directly and then hydroponically cultured. Choose a healthy cold spray, dig the plant out of the soil, gently shake off the excess soil from the roots, and then rinse the roots with water close to the soil temperature. After that, use scissors to cut off all the messy residual roots, diseased roots and rotten roots, leaving only some healthy and sturdy roots, soak the trimmed roots in diluted potassium permanganate solution for more than ten minutes, and then transplant them into hydroponic utensils.

3. The newly transplanted cold spray should pay attention to changing water every day and trim off some poor growth and rotting roots in time, until about a week later the plant begins to produce new roots, then you can begin to reduce the frequency of changing water.

Matters needing attention in cold water

1. When the cultivation time is too long and the growth is slow, it should be pruned in time, otherwise it will lead to the decrease of ornamental effect.

2. Cold spray likes strong scattered light, covering more than 70% of the sun in summer, the leaves will be burned if the sun is too strong, and there is no need for shading or slight shading in winter.

3, cold water overwintering temperature should be maintained above 13 degrees Celsius, long-term temperature below 10 degrees Celsius will be hurt, but a short time of 5 ℃ or so will not be injured.

4. The cold spray likes the humid environment and often keeps the spray moist and high air humidity. In the dry season, you can often spray water to the surrounding environment or foliage.

Disease and insect pest control of cold spray

1. 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.

2. Beetles. Control methods: beetle larvae usually live in the soil, so the soil should be disinfected throughout the year before planting. It is found that a larva should be removed in time, which is very difficult to destroy once it is propagated. When there are many beetles, they can be treated with chemicals. Remember to choose insecticidal agents as far as possible, do not choose pure pesticides, although the insecticidal effect is better, but it will have a certain impact on the growth after flowering. After spraying, root irrigation should be carried out to avoid residual eggs in the soil.

3. It is harmful to scale insects and is sprayed with 1000 times of omethoate. When root nodule nematodes are found, 3% carbofuran can be applied to control.

In fact, the water culture method of cold spray is not difficult, it grows slowly under high temperature in summer, and can not bear low temperature in winter, so seasonal care must be strengthened. It is also vulnerable to insect pests, so pest control work should not be slackened. Only by doing this well can we make it grow well.
