What effect does fertilizer have on potted flowers? In life, many people like to grow flowers and plants at home. Potted plants need fertilization and watering in the process of planting, but many people don't know much about fertilizers. What is the effect of sharing fertilizer on potted flowers?
What effect does fertilizer have on potted flowers? 1 nitrogen
Nitrogen fertilizer is also called foliar fertilizer. It can make plants grow rapidly, with lush foliage and dark green leaves. At seedling stage and flowering stage, nitrogen fertilizer should be mainly applied. It is usually applied from spring to early summer. In the prophase of plant growth, that is, vegetative growth period, nitrogen deficiency is more needed. If nitrogen fertilizer continues to be applied after the growth and development of plants stops (after summer), the stems and leaves will grow in vain, and finally the plants will be difficult to mature, which will seriously affect the flowering and fruiting. And the stems and leaves are weak and vulnerable to pests and diseases.
Therefore, the application of nitrogen fertilizer should be stopped before the plant enters the reproductive growth period (flower bud differentiation period). Human excrement, bean cake, ammonium sulfate and urea are all nitrogen fertilizers.
2. Phosphorus
Phosphate fertilizer is also called fruit fertilizer. It can promote flower bud differentiation and bud pregnancy, make flowers bright and fragrant, make fruits big and good in quality, and promote plant growth and health. It is most effective to apply it in the late growth period (reproductive growth period) of plants. Therefore, before flowering and after fruiting, more phosphate fertilizer can be applied. Plants have the ability to store phosphate fertilizer in vivo, which can be adjusted and used according to the growth needs, so they can all apply base fertilizer 1 time.
The ability of plants to absorb phosphate fertilizer is limited, and phosphate fertilizer will not cause fertilizer damage because of excessive application like nitrogen fertilizer. Poultry manure, poultry hair, bone meal, calcium superphosphate, potassium dihydrogen phosphate and phosphate rock powder are all phosphate fertilizers.
3. Potassium
Potassium fertilizer is also called root fertilizer. Can make stems and roots grow strong, not prone to lodging, and enhance the ability to resist pests and diseases and cold. It is indispensable in the early stage of plant development, and more potassium fertilizer can be applied at seedling stage, shoot-out stage and after seedling transplantation. In the later stage of plant development, potassium fertilizer contributes to the completion of photosynthesis and plays an important role in the production of carbohydrates, especially bulbous flowers, which can store a lot of carbohydrates.
Therefore, potassium fertilizer is indispensable in the whole process of plant growth. Potted flowers placed indoors for a long time can be applied with a large amount of potassium fertilizer because of insufficient light and weakened photosynthesis. Potassium fertilizer will not cause fertilizer damage due to excessive application. Plant ash, potassium chloride and potassium sulfate are all potash fertilizers.
What effect does fertilizer have on potted flowers? How to choose the right fertilizer for flowers?
First, choose fertilizer according to the growth stage of plants.
Plants use different fertilizers at different growth stages. For example, fertilizers with high nitrogen, low phosphorus and low potassium should be used at seedling stage, and fertilizers with low nitrogen, high phosphorus and medium potassium should be used at flowering stage. For some flower farmers, it is also appropriate to consult experienced people because they are not experienced enough and are not familiar with the details of fertilizer use.
Second, buy fertilizer according to the actual shortage of plants.
Plants will behave differently if they lack certain nutrients, and some people will buy some fertilizers indiscriminately. It often causes fat damage. The purchase and use of fertilizers should be based on the actual lack of nutrients in plants.
Third, buy fertilizer according to the cost performance.
Some people think that expensive fertilizer is good fertilizer, but it is not. At present, the most popular way to use fertilizer is to add 75% controlled release fertilizer and 25% water-soluble fertilizer, which is the most economical and effective. In the common people's mind, the price of controlled release fertilizer is high, which will increase the cost when used, but it is not. Water-soluble fertilizers will be wasted more in use. Controlled release fertilizer is a kind of coated fertilizer. If it is released according to the needs of plants, the waste of fertilizer can be reduced to a minimum and the efficiency is very high.
In addition, when selecting controlled release fertilizers, we should also pay attention to some explanations provided by suppliers, such as the differences in composition between different brands. Some brands of fertilizers have patented technology, which can promote the absorption of nutrients by plants. This information should provide a basis for selection.
