How to fertilize hydroponic flowers and plants?

Many friends have cultivated flowers and plants with hydroponic culture at home. Hydroponic plants are more labor-saving and labor-saving, but they also need to pay more attention to daily work, such as fertilization. Next, the editor will take a look at the fertilization skills of hydroponic flowers and plants.

1. Fertilizer selection: there is a special hydroponic plant nutrient solution on the market, which should be used in strict accordance with the instructions, grasp the fertilizer concentration, and never apply it blindly, otherwise it may cause fertilizer damage. In general, 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.

2. Fertilization time: hydroponic flower plants are generally fertilized in the vigorous spring and autumn season, and should be carried out in winter and summer. If plants suffer from malnutrition in summer, 0.1% urea solution can be sprayed on the leaves.

3. Fertilization concentration: the concentration of fertilization should be strictly controlled during fertilization, because all the nutrient elements applied are dissolved in water, and when the concentration reaches a certain height, it will cause fertilizer damage to flowers, thus affecting the growth of flowers and even leading to the death of the whole plant. 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 also according to the strength of plant growth to determine the application concentration, generally speaking, plants with strong growth potential 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.

4. fertilizer damage treatment: if the branches and leaves of flowers are weak and listless after fertilization, the leaves lose their luster and the roots rot and stink, which is the characteristic of fertilizer damage. Once the above situation occurs, 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.
