1. Selection of fertilizer
Hydroponic flowers need to be given special nutrient solution, which is generally not suitable for self-preparation. The soilless culture nutrient solution is prepared according to the nutrient ratio, concentration and acidity of the flower. In addition to the large amount of elements required by the plant, it also contains other trace elements. When using nutrient solution, the concentration of fertilization should be strictly controlled according to the requirements of the manual. Do not blindly apply it to avoid causing fat damage. The nutrient solution purchased should be placed in a dark place and at a low temperature, and should not be stored in a metal container. Different flowers have different requirements for fertilizer nutrients. Generally, the foliage plants should be based on nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers. The flower-flowering plants, especially in their flower bud differentiation and flower bud development stage, should be mainly phosphorus and potassium fertilizers supplemented with nitrogen fertilizer.
2, fertilization time
Hydroponic flowers should be fertilized in spring and autumn, and winter and summer are generally not suitable. If the flower is malnourished in summer and affects growth, a 0.1% urea solution can be applied to the foliage.
3, fertilization concentration
When fertilizing, the concentration of fertilization is strictly controlled, because the nutrients applied are all dissolved in water. When the concentration reaches a certain height, it will cause damage to the flowers, thereby affecting the growth of the flowers and even causing the whole plant to die.
1The concentration of different flower fertilization is not the same. The flowers such as scorpion scorpion, mini monstera, ruby, and sapphire are more resistant to fertilizer and fertilized. The roots are slender flowers such as Sihaibo, yarrow, and Begonia. The fertility of the genus and color-leaf grass is poor, and the fertilization should be lighter.
2 Hydroponic flowers should also be determined according to the strength of the plant growth potential. Generally speaking, the plants with strong growth potential are more resistant to fertility, and the fertilization can be relatively thicker, and vice versa. Indoor hydroponic flowers should stop fertilizing or reduce the concentration of fertilization in case of malnutrition, so as not to cause fat damage.
4, the treatment of fertilizer
If the branches and leaves of the flowers are weak and have no spirit after fertilization, the leaves are tarnished, and the roots are rotten and stinky, which is a characteristic of fat damage. Once the above situation occurs, the rotten root should be cut off in time, replaced with clear water and placed in the dark for maintenance, change the water once a day, and check the root of the flower, cut off the rotten root in time, until the new root is re-emerged, then transfer to normal Conservation.
