Fertilization of hydroponic flowers

　　 1. Selection of fertilizers 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. Nutrient solution to be purchased and placed in the dark at low temperature, avoid the use of metal container storage reservoir. Different flowers have different requirements for fertilizer nutrients. Foliage plants should generally nitrogen, supplemented phosphorus, potassium; plants flower bud differentiation and especially in its bud stage of development, should phosphorus, potassium is a front, supplemented with nitrogen.

　　 2. Fertilization time Hydroponic flowers should be fertilized in Spring and autumn, which are not prosperous. 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. Fertilizing concentration When fertilizing, strictly control the concentration of fertilization, because all the nutrients applied are dissolved in water. When the concentration reaches a certain height, it will cause damage to the flowers, thus affecting the growth of flowers, and even lead to the whole plant. death. 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. poor class, color leaf grass Naifei capacity, 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. Treatment of fertilizers If the flowers and leaves are weak and have no spirit after fertilization, the leaves are tarnished, and the roots are rotten and smelly, which is a characteristic of fat damage. Once the above situation should be promptly cut off the rot and put in the shade and water conservation, changing the water once a day and check the roots of flowers, cut the rot in time, until the re-germination of new roots, and then transferred to normal Conservation.
