What is soilless cultivation
Some family florists in the south of China often soak the rich bamboo stems without roots in vases. They can take root in about 10 days and grow well. After taking root, they don't have to plant with pot soil. Some other flowers and plants, such as Phyllostachys pubescens, can be cultivated and displayed in this way, which is called "hydroponics" p>
It is generally believed that soilless cultivation is hydroponic flower cultivation, but it is not. Hydroponic culture is only a method of soilless culture. If plants want to display and watch, they must first fix the plants so that they can grow independently without falling down. This requires fixing the roots with granular cultivation matrix or bean stone and perlite sold in the florist, and then injecting water into them for cultivation. Gravel culture, sand culture, leech right culture, asbestos block culture and plastic particle culture are commonly used, which are collectively referred to as soilless culture p>
Advantages of soilless culture
There is no space limit
Today, with the three-dimensional development of urban housing, soilless cultivation is especially suitable for flower cultivation in sporadic areas such as windowsill, balcony, hallway and desk. Using soilless cultivation method to raise flowers can eliminate the occurrence of underground diseases and pests, and will not emit odor due to fertilization of basin soil, let alone the need to prepare cultivation soil, which saves the trouble of loosening soil, weeding and turning basin for soil p>
Flowers grow stronger
More importantly, the nutrient loss of planting flowers in the basin soil is as high as 40% - 60%. The nutrient loss of soilless cultivation generally does not exceed 10%. If cultivated properly, flowers and trees generally grow stronger than those cultivated with pot soil p>
Soilless cultivation method
Selection of nutrient solution
When soilless cultivation is carried out in the flower field, the nutrient solution is prepared according to the different needs of various flowers and trees. The operation is quite complex and involves many problems, such as the composition of nutrient elements, the concentration of nutrient solution, the effectiveness of nutrient components, the consumption and supplement of nutrient elements, and the test of pH, etc. Family flower growers in soilless cultivation, there is no condition and no need to prepare their own nutrient solution, directly buy ready-made it p>
Replacement of nutrient solution
Nutrient elements will gradually oxidize and photochemical in the flower container, and the pH will lose balance, so they should be replaced in time. Indoor flower cultivation should be replaced once every 3-4 days. During replacement, the cultivation substrate must be thoroughly washed with clean water, and then injected with new nutrient solution diluted with water, otherwise the concentration of water will be higher and higher p>
