1. The choice of fertilizer
Hydroponic flowers need to be fed with specialized nutrient solution, and they are generally not suitable for their own preparation. The soilless culture solution is prepared according to the proportion, concentration, and acidity of flowers needed for the flower, and contains other trace elements in addition to the large number of elements needed for the plant. When using nutrient solution, it is necessary to strictly follow the requirements of the specification to grasp the concentration of fertilization, and do not apply it blindly so as to avoid causing damage. Purchased nutrient solution should be placed in dark places and low temperatures. Avoid using metal containers for storage. Different flowers have different requirements for fertilizer nutrient elements. The general foliage plants should be dominated by nitrogenous fertilizers, supplemented by phosphorus and potash fertilizers. The flowering plants, especially flower bud differentiation and bud development, should be dominated by phosphorus and potash fertilizers supplemented with nitrogenous fertilizers.
2. Fertilization time
Hydroponic flowers should be fertilized in spring and autumn with vigorous growth, and generally not suitable for winter or summer. If the flowers have malnutrition in the summer and affect growth, 0.1% urea solution can be sprayed on the leaves.
3. Fertilizer concentration
When fertilizing, the concentration of fertilization is strictly controlled because all the nutrients applied are dissolved in water. When the concentration reaches a certain height, the flowers will be fattened, thus affecting the growth of the flowers and even leading to the death of the whole plant. 1 The concentration of different flower fertilization is not the same. Fruits such as Hemerocallis, Mini Monstera, ruby, Hibiscus, etc. are more resistant to fertilization, and fertilization can be more concentrated; the delicate flowers of the roots such as the Four Seas Waves, the duck grasses, the begonias Type, color grass and other fertility are poor, fertilization should be lighter. 2 hydroponics flowers also depends on the strength of the plant growth to determine the application of concentration, in general, strong growth potential plants stronger fertility, fertilization can be relatively more concentrated, and vice versa should be lighter. Indoor hydroponic flowers should stop fertilizing or reduce the concentration of fertilization when malnutrition occurs, so as to avoid causing fertilizer damage.
4. Treatment of fertilizer damage
If the flower branches and leaves after fertilization are weak and inactive, the foliage loses its luster, and the roots rot and stench, it is a feature of fertilizer damage. Once the above situation occurs, the rot should be cut in time, put in fresh water and put it in the dark place for conservation, change the water once a day, and check the root of the flower, cut off the rot in time, until the re-emergence of new roots, and then into normal Conservation.
