Indoor Hydroponic Techniques for Flower Cultivation
Today's editor will explain the relevant experience of hydroponic flowers, indoor hydroponic flower cultivation techniques, and the specific contents are as follows:
Hydroponic flowers are cultivated in water as the medium, with flowers directly planted in containers filled with water and supplied with the necessary nutrients for growth, serving as a type of indoor green decoration.
I. Advantages of Hydroponic Flowers. Hydroponic flowers are clean and hygienic, have fewer diseases and pests, and are beneficial to human health; they are elegant and have a high ornamental value. Hydroponically grown flowers can be admired for their leaves, stems, and flowers, and also for their ever-changing root systems, enhancing the decorative aspect of the flowers. It also eliminates the trouble of finding and managing various potting soils for traditional potted plants, adapting to the high-efficiency and fast-paced characteristics of modern society. The diverse shapes and colors of flowers can be used to create artistic effects similar to flower arrangement by randomly configuring and arranging several types of flowers.
II. Types of Flowers Suitable for Hydroponics. Types of flowers suitable for hydroponics include herbaceous flowers such as black orchids, Cymbidium, Chlorophytum comosum, Cyperus alternifolius, purpleTradescantia, purple-backed Disocactus, Ophiopogon japonicus, Disochlia comosum, Zonium, and吉祥; woody flowers such as Jasmine, Pachira aquatica, Dracaena fragrans, Ficus benjamina, Osmanthus fragrans, kumquat, Chinese rose, Schefflera octophylla, Codiaeum variegatum, Rhapis excelsa, Hedera helix, and Dracaena draco; foliage plants such as Nandina domestica, Sansevieria, Monstera deliciosa, Sansevieria trifasciata, Rubrum, Caladium bicolor, Green巨人, Epipremnum aureum, Golden Empress, Silver Empress, variegated lucky bamboo, Green宝石芋, Syngonium podophyllum, Alocasia macrorrhizos, large-leafed Dieffenbachia, Variegated Dieffenbachia, and Starry Dieffenbachia; bulbous flowers such as Tulipa, Hyacinthus, Cyclamen, Narcissus tazetta, Calla lily, evening primrose, and Lily; succulent flowers include Disocactus, Echeveria, cacti, and宝石花.
III. Planting Techniques. Generally, a special hydroponic pot with a double-layered net screen and no bottom hole is used. For most households, containers with a certain level of transparency are suitable. The planting season is from mid-April to late June and from late September to early November. During this period, the temperature is suitable, and plant life activities are vigorous, making it easy for plants to root when planted or watered.
Select盆 plants with good appearance and strong growth, and rinse the roots with water to remove soil or other media. Weak plants with less nutrients and slower physiological activities are not suitable for hydroponic planting as it may affect root development and growth. For some flowers suitable for hydroponics, healthy semi-mature branches can also be cut during their vegetative growth period and inserted into water to root. For succulent plants with soft water-storing tissues in the stem, the cuttings should not be directly inserted into water but should be placed in a shaded and dry place for 2-3 days to allow the wounds to dry thoroughly before water insertion.
When planting, if the roots are very abundant, 1/3-1/2 of the fibrous roots can be pruned. Root pruning is beneficial for the regeneration of hydroponic plant roots, promoting early germination of new roots, and enhancing the plant's absorption of nutrients. After pruning, first soak the roots or base of the cuttings in a 5 g/L potassium permanganate solution for half an hour, then insert the roots into the mesh holes, trying to spread the roots out as much as possible, and handle them carefully to avoid further root damage. Use materials like vermiculite or ceramsite, and海绵 to securely fix the plant.
IV. Post-Planting Management. Whether it's a double-layered pot or a single-layer pot, regular water changes are key to successful hydroponic flower cultivation. As the plant roots grow in water, they produce mucus, which can pollute the water if it accumulates too much. In hydroponic culture, some mineral elements in the nutrient solution are absorbed by the flowers, while the rest remain in the water. When the accumulated substances reach a certain level, they can harm the plant's growth. The oxygen content in the water decreases as the plant grows, and when it decreases to a certain amount, it affects the plant's growth.
For most normal-growing flowers, the water should be changed once every 7-10 days in summer, every 15 days in spring and autumn, and every 15-20 days in winter. When changing water, the mucus on the roots should be washed off, and the rotting roots and yellow leaves should be cut. For newly potted hydroponic flowers, because they have more wounds on their roots that are prone to rot, the water should be changed frequently, especially during high temperatures when the oxygen content in the water is reduced, and the plant's respiration is stronger, consuming more oxygen. Once white new roots grow in the water, the frequency of water changes can be gradually reduced.
Before changing the water, first pour out the accumulated water in the outer pot, then wash the inner pot's substrate or the single-layer pot with clean water repeatedly to wash away the remaining nutrient solution; at the same time, wash the plant's roots with water. Then, pour in fresh nutrient solution. Normally, when 20%-30% of the water is consumed, it is necessary to add water; be careful not to fill the water too full, leaving some roots exposed to the air.
Under hydroponic conditions, all the fertilizer applied is dissolved in the water, and if its concentration slightly exceeds what the plant can tolerate, it can cause fertilizer damage. Therefore, hydroponic flowers should generally be fertilized with a specific nutrient solution. The nutrient solution is formulated according to the plant's required nutrient ratio, concentration, and pH.
The suitable growth temperature for indoor hydroponic flowers is between 18-25°C. If the roots of hydroponic flowers are frequently in high-temperature nutrient solution, they can turn black and brown; in severe cases, they may rot and lead to the death of the entire plant. Therefore, during the summer, prevent direct sunlight on the water pots to avoid overheating the water and damaging the plant roots. When flowers are overwintering, avoid cold air invasion to prevent frost damage. Heating methods such as watering the ground with hot water or using a hot air blower can be used.
