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.

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.

How to choose hydroponic flowers? Key points of selection of hydroponic flowers

How to choose hydroponic flowers? When choosing hydroponic flowers, the most important and important thing must be according to their own liking, knowing that what they like is the most important. Of course, under this premise, the flower is required to adapt to the local environment. Today, the editor will talk about the key points of hydroponic flower selection from several aspects, hoping to be helpful to everyone.

1. Personal preferences

If you have no requirements for hydroponic flowers, you can choose varieties that have strong adaptability, simple cultivation and management, and can improve the environment, such as tiger orchid, hanging orchid, white crane taro, tortoise back bamboo, rich bamboo and so on. And if you have requirements for flowers, you can choose according to your preferences and economic ability. If it is only pure love, it is of little value to the environment, and requires special environmental conditions and higher cultivation techniques, then it is best not to choose this kind of variety.

2. Setting up the environment of flowers

Large space planting or plant shape, you can choose tall hydroponic flowers, otherwise choose small plants. If economic conditions permit, you can choose plants that are graceful and can match the home space in height and size.

3. Habits of hydroponic flowers.

Before choosing a family hydroponic flower, it is necessary to understand the growth characteristics and growth rate of the flower, and finally roughly how high and how much information can grow.

4. The level of cultivation and maintenance

Before choosing hydroponic flowers, consider how much time and experience you have to manage. For example, if you are an office worker, you can choose flowers that are easy to grow, which can adapt to a wide range of environment, such as tiger tail orchid, green apple, rich bamboo, hanging bamboo plum, Guangdong evergreen and other plants. If you have some experience in growing flowers and have more time to manage yourself, you can try to cultivate flowers that are more demanding to the environment, such as taro, some tropical orchids, national orchids, cactus and succulent plants, as well as woody plants.

Knowledge, skills and points for attention of ✤ hydroponic flowers 1. Hydroponic flowers can not use metal containers when preparing nutrient solution, let alone use it to store nutrient solution. 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 the water should also be paid attention to when preparing nutrient solution. If tap water is used, tap water should be treated. To prevent harmful substances in water from causing damage to plants, it is necessary to add a small amount of humic acid compounds or sodium ethylenediamine tetraacetate. 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.
