Can Gladiolus be hydroponically cultured? the hydroponic culture method / water exchange frequency of Gladiolus is crucial.

In order to decorate the home and beautify the environment, more and more people will plant several pots of plants at home. Gladiolus is one of them. We know that gladiolus has many functions and effects, and viewing is the most important role. If you want to watch the effect, what is the best planting method? The answer is hydroponics. So can Gladiolus be hydroponically cultivated? If you can gladiolus hydroponic culture method is how to raise it? Let's take a look.

Can Gladiolus be cultured in water?

Scientific research shows that Gladiolus is also a plant that can be hydroponically cultured, but its rhizome is a bulb, so some skills need to be paid attention to during hydroponics, such as the selection of plants, the treatment of rhizomes, the frequency of changing water, the addition of nutrients, and so on.

Aquaculture method of Gladiolus

1. Plant selection

In order to make the gladiolus have a good foundation after hydroponic culture, the plants must be selected, and the bulbs with large bulbs and solid appearance should be selected. Such plants show that the bulbs are relatively strong and can store more nutrients.

2. Rhizome treatment

Remove some of the older stems from the bulb, and then make a few cuts with a tool where there is no bulb, which helps Gladiolus to take root quickly after hydroponic culture, and the treated rhizome can be put into a hydroponic container.

3. Add water

Add water to the hydroponic container, the water used must be clean and hygienic, generally use tap water, but the alkalinity is too high can be placed for a few days. The height of the water level is about 1 cm. It is not necessary to soak all the bulbs in water and then put them in a cool place to wait for the buds to sprout.

4. Temperature

In the method of hydroponic culture of Gladiolus, temperature is the key factor affecting its growth rate. If there are conditions to keep the temperature at 20-25 degrees during the day and 10-15 degrees at night, the temperature must not be too high or too low, otherwise the growth will stop.

5. Change water

Before sprouting, the water can be changed once every 10-15 days, and once every 3-5 days after shaping. If the water is not changed for too long, it is easy to cause the growth of microorganisms in the water, which is disadvantageous to the growth of gladiolus, and it is also easy to produce rotten roots. Changing water frequently can effectively avoid this problem.

6. Nutrition

Hydroponic gladiolus also needs enough fertilizer, and some solid fertilizer can be added appropriately when changing water, but the most suitable fertilizer is the nutrient solution purchased from a professional florist, which is specially allocated according to the nutrition needed by gladiolus. Add a few drops each time you change the water.

Flower water culture

I. definition of hydroponic flowers

Hydroponic flower culture is a new generation of high-tech agricultural project, which uses modern bioengineering technology, physical engineering, chemical engineering and bioengineering means to domesticate and induce ordinary flower boats to grow normally in water. It uses original modern biological improvement technology to make the original flower boat plants adapted to the terrestrial environment through short-term science and technology domestication, improvement and cultivation, so that they can quickly adapt to the aquatic environment. Hydroponic flowers, the upper half of the flowers are luxuriant, the lower half of the fish play, strong ornamental, can enjoy the flowers, roots and fish. It is green, environmentally friendly, clean and convenient, so hydroponic flowers are also called "lazy flowers".

2. study on hydroponic flower abandonment and seedling raising.

The process of hydroponic culture of flowers is actually the process of aquatic mutagenesis, which refers to the process of promoting the formation of ventilated tissue between plants and root tissues under the stress of anaerobic environment. under the stress of anaerobic environment, it stimulates the rapid formation of unique molecular mechanism, physiology and biochemistry in plants, so as to realize the process of forced adaptation and active adaptation. In this process, the creation of anaerobic signal is the key signal to close and open the formation of ventilated tissue, the formation of metabolic mechanism and physiological and biochemical changes. Oxygen free radicals, ethylene signals, hormone signals and signals are all direct signals or cascade reaction signals produced under anaerobic conditions. Under the action of these signals, the expression of related genes is initiated, thus realizing the adaptation transition from terrestrial to aquatic environment and the transformation of metabolic morphology.

The common woody flowers in Hunan are: cycad, gardenia, happiness tree, mandarin, rubber lattice, jasmine, Malaba chestnut, Brazilian wood, weeping leaf banyan, sweet-scented osmanthus, camellia, kumquat, goose palm wood, variable leaf wood, palm bamboo, ivy, red leaf heather, five-needle pine.

Herbaceous flowers are mainly: ① foliage flowers: tortoise back bamboo, tiger tail orchid, asparagus, Phnom Penh rich bamboo, flower leaf hand, hulk, green apple, taro, evergreen flowers and leaves. ② perennial root flowers: carnation, asparagus, African chrysanthemum, chrysanthemum, calla lily, rose, gladiolus. ③ ball lotus flowers: hyacinth, cyclamen, tulips, daffodils, calla lilies, evening jade, magnolia and so on. ④ Flower Boat: crab claw orchid, mountain shadow spring, cactus, gemstone flower, Guanyin lotus. ⑤ others: Oncidium, Mulan, hanging Orchid, hanging Bamboo Plum, auspicious Grass, Phalaenopsis, hanging Golden Bell upside down.

Herbaceous and woody hydroponic flowers are concentrated in the following families: green pineapple of ① Araceae, Guangdong evergreen, Daifen evergreen, silver emperor, golden queen, tufted spring feather, peacock bamboo, mini tortoise back bamboo, tortoise back bamboo, silver Xun taro, emerald, happy forest taro, Qin leaf Xi Lin taro, green emperor happy forest taro, synthetic fruit taro, sea taro, crane flower, emerald and so on. The purple-leaf duck grass of the family ②, purple back evergreen, light bamboo leaves, hanging bamboo plum and so on. ③ Liliaceae aloe, triangular aloe, dotted 12 volumes, hanging orchid, Zhu banana, dragon blood tree, horsetail iron, tiger skin orchid, tequila, Phnom Penh rich bamboo, sea onion, silver edge evergreen, silver edge step grass and so on. ④ crassulaceae lotus palm, hibiscus palm, silver wave brocade, gemstone flower, falling to the ground and so on.

III. Induction of hydroponic roots of hydroponic plants

Hydroponic culture is a process that induces the formation of plant aquatic roots and can grow and develop normally in nutrient solution. Therefore, the formation and growth of aquatic roots is the core of this technology. Hydroponic flower boat is the use of modern physics, chemistry, biotechnology and other comprehensive technical measures, different varieties of flowers in the rooting medium, the rooting rate is greatly affected by environmental conditions and their own biological characteristics. First of all, the difficulty of the formation of aquatic roots of different plants is different, herbaceous plants are fast and easy, woody plants are slow and difficult; plants with large intercellular spaces are easy, but it is difficult for plants with slow cell growth rate to arrange tightly; wet terrestrial plants that like shade are easy, such as Araceae plants, and drought-tolerant terrestrial plants that like sunlight are difficult, such as peach trees. The morphology of aquatic roots of different plants is also different, but the regularity is similar. Compared with terrestrial roots, aquatic roots are mainly fibrous roots, and the root hairs are less or degenerated. At this time, the water environment makes the plants have physiological changes. Then the creation of a suitable water environment is the focus of our technology, and only in a suitable water environment can we promote the continuous formation and development of aquatic roots, such as dissolved oxygen in water is a necessary condition for root breathing. once the rooting of anoxic water will be inhibited or even turn brown and rot, so it is necessary to carry out computer real-time detection and control of oxygen in the process of mutagenesis.

In addition, suitable water temperature and appropriate concentration and water level of nutrient solution will affect the culture of aquatic roots, which must be controlled by computer. These technologies are the core of hydroponic culture of all plants. Without computer control, it is difficult to realize water root culture, especially for mutagenic plants. The root induction under hydroponic environment has higher root activity, and the stele part of terrestrial plants has no obvious change in the aquatic environment, but the cells of cortical parenchyma will produce cracks and form aerated tissue similar to rice root system. to adapt to the aquatic environment. The morphological structure and physiological activity of aquatic-induced roots changed accordingly under some conditions of fresh water, in order to adapt to the normal growth under hydroponic conditions. The induction methods mainly include the treatment of temperature, light, water, regional dissolved oxygen, nutrient solution and hormone to find the most suitable induction environment. Different flower boats have different degrees of difficulty in aquatic mutagenesis.

4. the methods of root induction are as follows:

The main results are as follows: (1) Matrix treatment: the stomatal parameters of Cymbidium were studied under the conditions of ceramsite revolving irrigation nutrient solution, perlite Rao irrigation nutrient solution, Shuishi Rao Irrigation nutrient solution, general nutrient solution hydroponic culture and soil cultivation. The results showed that the stomata of the leaves were oval or round, and the guard cells were semilunar. The stomatal distribution near the leaf tip and the middle part of the leaf is obviously more than that of the leaf base and leaf edge, and the degree of stomatal distribution is relatively small for the leaf base, and the stomatal density decreases slowly from the leaf tip to the leaf base, which is shown as: the leaf tip in the leaf base. The stomatal parameters of lower epidermis in the middle part of Cymbidium leaves under different substrate cultivation were compared: the area of single stomata in soil culture was the smallest, which was significantly lower than that in general nutrient solution, Shushi Rao irrigation solution and haydite Rao irrigation solution, and the maximum stomatal index in the middle part of leaves treated by soil culture was significantly higher than that in water culture, Shushi irrigation solution and ceramsite irrigation solution treatment.

(2) treatment of plant growth regulators: natural plant hormones and synthetic hormones have similar physiological effects, so synthetic hormones have been widely used in horticultural plant production to control plant growth, protect flowers and fruits, increase yield, keep fresh and endure storage, promote cutting rooting, improve grafting survival rate and so on. The aspect plays a very important role. The commonly used general hormones are NAA (naphthylacetic acid), IAA (indoleacetic acid), IBA (indolebutyric acid) and ABT (rooting powder). The results show that he is the most suitable concentration for hydroponic ivy cuttings, and the newly synthesized phosphonic acid cool compounds can significantly increase the rooting rate, rooting number and root length of cutting chrysanthemum, and have the best effect on water rooting of hibiscus. Among them, many kinds of plants are often used in hydroponic experiments, such as Guangdong evergreen, oleander, Phalaenopsis, Anthurium andraeanum, at the same time, root cutting, shading and water level also have certain effects on root induction. In the process of hydroponic culture, the roots induced by cutting off the original main roots are more suitable for hydroponic culture than those without shading, and the roots induced by root shading grow better than those without shading.

(3) Water insertion method: generally used in aquatic environment for plant species that are easy to take root and grow fast, such as tortoise back bamboo, emerald, rich bamboo, ruby, Dutch iron, sea taro, colorful iron, green pineapple, auspicious grass, cymbidium, hanging orchid, daffodil and so on. Select healthy, pest-free and sturdy branches, wipe them with alcohol cotton balls, cut them at the millimeter under the branches with scissors, insert them into the water, and then carry out hydroponic culture after rooting. If the branch has aerial root when cutting, the aerial root should be protected and inserted in water. The root system of water-inserted seedlings grows in water, the root system is intact and robust, the color is beautiful and not perishable, and the growth is exuberant.

(4) Root trimming method: this method is mostly used for formed plants, and different methods are adopted according to the degree of difficulty of plant rooting, including: complete root removal, root removal and root cutting without root removal. Some of these plants are not easy to take root in water, such as palms, pocket coconuts, wine bottle orchids and so on. Larger plants, such as tortoise back bamboo, sea taro, and flowering plants such as du, camellia, Ruixiang, longevity flowers, Zhu Dinghong, stone sowing, calla lilies, tiger plums, etc., often do not remove roots. Choose ornamental value, plant health, strong growth, soil culture or other media to cultivate formed plant flower boats, move the potted plants with roots, remove the soil, rinse the root soil with water and cut off part of the roots and all rotten roots. Then hydroponic culture. When cleaning the roots, it is suitable to use flowing water, then soak in surface disinfectants such as potassium permanganate, bromogeramine or carbendazim for minutes to remove bacteria, and finally use stones or perlite to fix the plants in prepared containers and inject them with rootless water. At the beginning, change the water once a day to keep the dissolved oxygen in the water, while cleaning the container and root. 1After a week, the frequency of changing water can be reduced until the white effluent of the cultivated Huajing takes root, indicating that it has adapted to the water environment, and then you can change the water every day or even longer. Plants that are relatively easy to take root, such as Lingxiao, can also be disinfected and hydroponically cultured after root washing. After the cactus is completely removed from the root, it is dry and mounted on the container containing water, the bottom of the cactus can not touch the water, and the new root can be induced by the evaporation of water in the container.

(5) the method of stripping tiller buds: it is suitable for flower boats which are easy to sprout tillering buds in the root neck, such as Shiquan, boxwood, privet, oleander, Phalaenopsis, pineapple, etc., with simple steps and high survival rate. Select strong and healthy tiller buds, cut them along the root neck with a knife, cut buds more than cm long into a horseshoe-shaped section, retain tips and leaves, protect the integrity of tiller buds, wash the soil attached to the roots, and culture the roots in water and expose them to the water.

(6) the method of taking stolon: some flower boat plants can produce several stolon lotus in the process of growth, these lotus have nodes, and the nodes take root and grow buds, such as herb poison, hanging orchid, pineapple and so on. It is very simple to use this characteristic of flower boat plants to intercept the hydroponic culture of small plants on stolon.

What are the techniques of hydroponic flower culture

Hydroponic flowers are a kind of flowers with excellent ornamental nature. the upper flowers of hydroponic flowers are full of fragrance, and the fish below can also play at will, which is not only sanitary and environmentally friendly, but also very convenient, so hydroponic flowers are also called lazy flowers and are good helpers for home decoration. suitable for living room, bedroom, balcony, study and courtyard and other places. Today, what the editor shares with you is the introduction of hydroponic flowers and plants and some knowledge and skills of hydroponic flower culture.

Characteristics of hydroponic Flower plants

The appreciation of hydroponic flowers is very strong, not only with artistic vase shape, but also with white aquatic roots and different color substrates, and what is even more peculiar is that flowers and fish can be cultured together. Many kinds of ornamental effects, such as flowers, leaves, roots and fish, are integrated, and hydroponic flowers are cultured in water without soil, so there is little disease, insect pests and fungi and bacterial pollution. Water and nutrient management is also more convenient, maintenance is simple and does not need frequent watering, can play the effect of beautifying the space.

Culture techniques and matters needing attention of hydroponic Flowers

1. Hydroponic flowers cannot use metal containers when preparing nutrient solutions, let alone use them to store nutrient solutions. in order to be beautiful and conducive to the growth of plants and flowers, it is best to use glass, enamel and ceramic utensils as containers. and when preparing the nutrient solution, the water also needs to be paid attention to, if tap water is used, tap water should be treated to prevent harmful substances in the water from causing harm to plants. A small amount of humic acid compounds or sodium ethylenediamine tetraacetate need to be added.

2. when hydroponic flowers are cultivated in pots, the cultivation water in the pot generally needs to be changed once a month or two, and tap water can be used, but we must pay attention to the use of tap water for a period of time to keep the root temperature stable. And most hydroponic flowers are negative and neutral flowers suitable for indoor cultivation, and there are different requirements for light. The whole root or root mouth of hydroponic plants with proper light, temperature and nutrient solution concentration is white.

Conclusion: there are many kinds of hydroponic flowers, and they are highly ornamental, beautiful and generous. Transparent glass bottles are used in living rooms, bedrooms, balconies, studies and courtyards are very good decorations and handicrafts, which can not only add color to home life, but also highlight the unique taste of the host. The above is the editor's introduction to what hydroponic flowers and plants have and some knowledge and skills. I hope it can help friends who like hydroponic flowers.
