Hydroponics and aquaculture are quite different.
Do you understand these? Knowledge about hydroponic flowers, hydroponics and aquaculture are quite different. Next, the site editor will introduce to the netizens.
In recent years, some hydroponic and aquaculture flowers have been favored by people for their fresh and environmental protection, elegant style, easy maintenance, and convenient combination. On the surface, the cultivation forms of hydroponic and aquaculture flowers are the same, that is, liquid maintenance, so many people confuse the two. In fact, they are明显 different.
Flowers used for aquaculture generally have swollen bulbs that store rich nutrients, and their growth and flowering mainly rely on the nutrients stored in them. When cultivating, only the roots need to be soaked in clean water and fixed, without the need to supply nutrients. Suitable flowers for aquaculture mainly include narcissus, tulips, hyacinths, and lucky bamboo. To make aquaculture flowers grow lush and bloom beautifully, the key is to choose fully developed bulbs to provide the necessary nutrients for their growth; secondly, change the water frequently, preferably every 2 to 3 days (every 7 to 10 days for lucky bamboo) to maintain sufficient oxygen in the water and improve root activity; thirdly, maintain sufficient sunlight for healthy growth.
Hydroponic flowers, on the other hand, involve fixing the plant roots on the lid or floating plate of the flower pot and immersing the roots in water, which must be supplemented with a reasonable amount of inorganic nutrients, so hydroponic flowers are also known as nutrient solution culture. Flowers suitable for hydroponics have plant habits and internal structures that allow them to grow normally in water. The main varieties currently cultivated include kaffir lily, hanging orchid, cattleya, Brazilian wood, Chinese evergreen,丛生春芋, turtleback bamboo, gem flowers, hanging bamboo plum blossom, and落地生根 plants.
Northeast University in China has developed 9 series and more than 500 hydroponic flowers through 8 years of effort using biotechnology mutation technology, including herbaceous flowers, woody flowers, cacti and succulent plants, as well as ornamental flowers such as kaffir lily and butterfly orchid. With the advancement of technology, some high-end flowers imported from abroad in recent years, such as pineapple, red candle, and scarlet lily, have also successfully been hydroponically cultivated. Some unique Chinese flowers, such as tiger's tongue orchid, have also been domesticated for hydroponics.
The roots of truly mutated hydroponic flowers have changed in character, with root hairs退化 and most being straight roots that grow vertically, unlike the roots and root hairs of aquaculture plants, which are reticulated. After aquaculture mutation, the plant's aquatic root genes are expressed, so the leaves of true aquatic flowers become larger and thicker, and the leaves and branches are fresher and tenderer than those grown in soil.
The key to hydroponic flowers is to prepare a good nutrient solution. When preparing nutrient solutions, avoid using metal containers or containers that have held oils, acids, or bases. When using tap water to prepare nutrient solutions, add a small amount of humic acid compounds to treat chlorides and sulfides in the water. Hydroponic flowers should have their nutrient solution added or replaced once a week, and the pH value should be controlled between 5.5 and 6.5. The discarded nutrient solution can be used as fertilizer for other crops.
