First, timely fertilization. Timely fertilization is applied when flowers need fertilizer. It was found that the lightening or yellowing of the mosaic leaves and the optimum period for fertilization when the plant growth is delicate. In addition, when the flower seedlings have leaves, the branches need to be top-dressed to meet the needs of the fast-growing seedlings. The different stages of flower growth require different fertilizers. There are also differences in fertilization types and fertilization rates. If nitrogenous fertilizer is applied at the seedling stage, seedling growth can be promoted, and the application of phosphate fertilizer during flower buds can promote large and bright flowers and long flowering period.
Second, apply fertilizer adequately. Potted flowers and fertilization should be done to â€œeat fewer mealsâ€, that is, the number of fertilization is more, and the amount of fertilizer should be less each time. Generally, a thin fertilizer is applied every 7-10 days. With the gradual growth of flowers and trees, the concentration of fertilizers gradually increased, such as the concentration of urea from the previous 0.2% gradually increased to 1.0%; phosphorus and potassium fertilizer increased from 1.0% to 3.0-4.0%.
In addition, fertilization temperature. Potted flowers should not be fertilized before and after noon at high temperature or on rainy days. At this time, fertilization is easy to injure the roots. It is best to fertilize in the evening. When the temperature is low, flowers do not grow normally with slow growth. Summer temperatures are high. When the flowers are growing vigorously, more fertilizer should be used. When the temperature is high, the concentration of topdressing fertilizers should be low, and the amount should be less. The fertilizer should be chased more often with thin fertilizers.
Again, the drug and fertilizer are mixed. When pests and diseases occur during fertilization, suitable pesticides can be added to the fertilizer solution, which can play the dual role of fertilization against pests and diseases.
Finally, apply more organic fertilizer, less fertilizer, and appropriate amount of bacterial fertilizer. Organic manure not only contains three important elements of nitrogen, phosphorus, and potassium, but also trace elements and growth stimulating hormones, which have the most demand for growth. It plays an important role in promoting its growth. In particular, organic fertilizers that have been treated with a starter (such as a goldfish starter) can also improve soil structure and increase soil water retention. Although chemical fertilizers have a relatively rapid fertilizer effect, they can easily cause soil compaction and reduce soil microbial content if used in large quantities. Bacterial fertilizer contains a large number of nitrogen-fixing, phosphate-releasing and potassium-releasing functional bacteria, such as golden treasure microbial fertilizer, which can effectively increase fertilizer utilization, regulate soil structure, and improve flower appearance quality.
