Fertilization of hydroponic Flowers

one. The choice of fertilizer hydroponic flowers need to be applied into a special nutrient solution, usually not suitable for self-preparation. The nutrient solution of soilless culture is prepared according to the proportion, concentration and acidity of nutrients needed by flowers. it contains not only a large number of elements needed by plants, but also other trace elements. When using nutrient solution, you should solemnly abide by the pleas of the instructions, control the concentration of fertilizer, and do not apply it blindly, so as not to cause fertilizer damage. The nutrient solution you buy should be placed in a dark place and at a low temperature, and do not use metal containers. Different flowers have different pleas for fertilizer nutrients. Generally speaking, foliage plants should be mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer, while flowering plants, especially in the stages of flower bud differentiation and flower bud development, should be dominated by phosphorus and potassium fertilizer, supplemented by nitrogen fertilizer.

two. In the time of fertilization, hydroponic flowers should be fertilized in spring and autumn, but not in winter and summer. If the growth of flowers is affected by malnutrition in summer, 0 can be sprayed on the leaves. 1% urea solution.

three. The concentration of fertilizer is majestic to control the concentration of fertilization, because all the nutrient elements are dissolved in the water, when the concentration reaches a certain height, it will cause fertilizer damage to flowers, thus affecting the growth of flowers, and even lead to the death of all plants. ① different flowers fertilization concentration is not the same, fruit taro, mini tortoise back bamboo, ruby forest taro and other flowers are more fertilizer-tolerant, fertilization can be thicker; flowers with slender roots, such as Sihai wave, duckfoot grass, begonia, colored leaf grass and other fertilizer tolerance is poor, fertilization should be lighter. ② hydroponic flowers should also be based on the strength of plant growth to determine the application concentration, generally speaking, the plants with strong growth have stronger fertilizer tolerance, fertilization can be relatively dense, and vice versa. When indoor hydroponic flowers are malnourished, they should stop fertilizing or reduce the concentration of fertilization, so as not to cause fertilizer damage.

four. The solution of fertilizer damage is that after fertilization, the branches and leaves of flowers are delicate and listless, the leaves lose luster, and the roots are eroded and smelly, which is the characteristic of fertilizer damage. Once the above situation emerges, you should cut off the rotten roots in time, change the water and put it in a dark place for maintenance, change the water once a day, and check the roots of flowers, cut off the rotten roots in time, until the new roots germinate again, and then transfer to normal maintenance.
