What is the effective interval between the fertilization effect of flower seedlings after fertilizat

About fifteen to twenty days or so.

Pay attention when fertilizing.

1) Fertilization should pay attention to the type of flowers. Different kinds of flowers have different requirements for fertilizer. For example, osmanthus and camellia like pig manure, and avoid human feces and urine; Rhododendrons, camellias, masts and other southern flowers avoid alkaline fertilizers; Flowers that need to be re-pruned every year need to increase the proportion of phosphorus and potassium fertilizer to facilitate the germination of new branches; Flowers with foliage as the main focus can be more nitrogen fertilizer; Flowers such as chrysanthemums, dahlias, etc., need to be applied with an appropriate amount of complete fertilizer during the flowering period to make all the flowers open and beautiful; For flowering flowers, fertilizer and water should be properly controlled during the flowering period, and sufficient complete fertilizer should be applied during the fruit-strengthening period to achieve the expected effect. bulb flowers, apply more potassium fertilizer to facilitate bulb enrichment; Fragrant flowers, enter the flowering period, apply more phosphorus and potassium fertilizers to promote the fragrance of flowers.

2) Fertilization should be mastered at the right time and in the right amount, and at the same time, the season and time should be mastered. Generally speaking, fertilization is best when the flower leaves are pale yellow and the plants are weak; Vegan fertilizer was applied at the seedling stage, phosphorus fertilizer was mainly applied at the flowering and fruiting stage, and nitrogen fertilizer was mainly applied to foliage flowers. In winter, the temperature is low, the plant grows slowly, and most flowers are in a state of growth stagnation, and generally no fertilizer is applied; Spring and autumn are the peak period of flower growth, roots, stems, leaves grow, flower buds differentiate, young fruits swell, all need more fertilizer, should be appropriately applied more top dressing; In summer, the temperature is high, the water evaporates quickly, and it is the vigorous growth period of flowers, so the concentration of top dressing should be small, and the number of times can be more.

The specific fertilization time is generally in the evening, and fertilization should not be avoided around noon, because the soil temperature is high at noon and it is easy to hurt the roots. Generally, it is necessary to master the "four more, four less, and four no", that is: yellow and thin more, more before germination, more before pregnancy, and more after flowering; Less application for growth, less application for germination, less application for flowering, and less application in the rainy season; Don't apply for long, don't apply for new planting, don't apply for summer, don't apply for dormancy.

3) It is necessary to grasp the principle of "thin fertilizer and diligent application", that is, "eat less and eat more".

The effective interval of fertilizer effect is generally on the packaging bag, depending on whether you use fast-acting fertilizer or slow-release fertilizer, and the fertilizer effect of farmhouse fertilizer is longer than that of chemical fertilizer, so it depends on fertilizer.

Thin fertilizer is of course better for plants, but it is labor-intensive, so it is still necessary to master a degree.

I used to grow Phalaenopsis orchids, and I also used drip irrigation ponds with chemical fertilizers, basically watering twice as much as fertilizer and then twice as water. Then look at the growth rate to adjust the fertilizer ratio, I have never planted carnation roses, but the fertilizer is considered a fast-acting fertilizer, I think about fifteen to twenty days or so to apply fertilizer is good, you adjust it yourself.

The fertilization effect is seen a few days after fertilization.

To judge whether the plant is deficient in fertilizer, you can directly observe the leaf color, the plant leaf veins are thick and the leaf color is dark, which means that the nutrients are sufficient and do not need to be fertilized, if the leaf veins are small and the leaf color is light, then fertilization is required.

In addition, you can also touch the leaves with your hands, the leaf edge is curved, and the leaves are thick, indicating that the fertilizer is very sufficient, and there is no need to apply fertilizer, on the contrary, there is a lack of fertilizer.

1. No fertilization.

It is some organic fertilizer that has not been fully fermented and decomposed, flower friends know that the effect of raising flowers with organic fertilizer is good, but the raw fertilizer that has not been fermented must not be used directly, if raw fertilizer is used, then the fertilizer will produce heat in the process of rotting in the pot soil, which is easy to burn the root system and attract small black flying, which is not conducive to the health of flowers.

2. Do not apply thick fertilizer.

As long as it is a potted plant, it is never recommended to apply thick fertilizer, fertilizing plants should always follow the principle of "thin fertilizer diligently, rather less than more", the fertilizer concentration is too large to "burn" the roots of the plant, resulting in blackened leaves, scorched and infertile buds do not bloom, and in serious cases, it will cause death.

3. The roots should not touch the bottom fertilizer.

For some plants that like fertilizer, such as Junzi orchid, tiger orchid, crab claw orchid, longevity flower, etc., flower friends will habitually add some base fertilizer to the bottom of the pot when potting them, but remember not to let the root system directly contact the bottom fertilizer, otherwise the fertilizer effect is too strong and harmful to growth, so add the bottom fertilizer and then cover it with a layer of soil, and then pot it.

It depends on whether you are planting in the ground or in pots, you don't need to be so diligent in ground planting, and potted plants can be relatively diligent. If human and animal manure is used, it must be decomposed and diluted before application, otherwise it will be hypertrophied and burned. Regarding fertilization, there is"Look at the four"with"Four taboos", for your reference Four look at the growth of the situation:

Thin leaves and yellow bodies, pregnant buds before buds, and flowers should be fertilized more; The leaves are green and the stems are strong, the flowers are fruitful and the buds are long, the new plants are waiting to sleep, and the disease and withering are all less or no fertilization. Second, look at the sky: apply more in spring and summer to reduce in autumn, stop fertilizing and dormant sweet in cold winter, do not fertilize in rainy days, avoid strong light and apply in the evening.

Three look at the potting soil: the potting soil is too acidic and neutralizes alkali (lime or plant ash, etc.), the potting soil is too alkaline and alum, the potting soil is added with white fertilizer, and the potting soil aggregate elements are complete. Four categories of flowers:

Herbaceous phosphorus is preferred, bulbous potassium fertilizer is first, and woody flower fertilizer is complete. The so-called "four taboos" are: one taboo is excessive application of thick fertilizer; Second, it is forbidden to sit on fat and burn roots; Three taboos are partial to the application of a single fertilizer; Fourth, avoid raw fat and not rotten.

There is no need to fertilize small seedlings when they sprout, especially when the buds and leaves are red, so as not to hurt the buds and roots. When the buds are big and the seedlings are strong, you can apply thin fertilizer and apply it frequently (spring and summer are the vigorous growth period of small trees), and you can do it once a week or two or even once a month or two

Generally, once a half month is fine.

How often to use organic fertilizer for raising flowers should be determined according to the variety and growth of flowers. No matter what kind of flowers you are, you need organic fertilizer, and the nutrients are sufficient to bloom and grow better. Some have to be applied once a month, such as moon flowers, roses.

There are also seedlings that can be applied once a year, in the autumn of each year, which is more conducive to the growth of the next year.

Family flowers generally do not need too much fertilizer, especially the more popular foliage flowers for the Brazilian iron pillar, fortune tree, etc., because to maintain the original plant shape, to prevent aging, generally in the spring and autumn rainy season each fertilization 12 times, other vigorous flowers, generally once a month can be fertilized, fertilizer can be selected with nitrogen, phosphorus and potassium compound fertilizer 500-800 times.

Avoid fertilization in high temperature and scorching sun weather At noon in summer and autumn, the temperature is high, the light is strong, and the transpiration of plant leaves is strong, and it is easy to cause physiological and metabolic disorders in the plant after fertilization, causing yellowing of branches and leaves, and wilting of flowers. Therefore, it is not advisable to fertilize at noon in summer and autumn, but to choose early morning or afternoon after high temperature, combined with watering and fertilization. Avoid fertilization on rainy days and at night Rainy days in early spring or late autumn and low temperature at night reduce root absorption and low fertilizer utilization.

At the same time, fertilizer is also easy to accumulate in the soil, coupled with the influence of water and air sealing, it is easy to cause flowers to hurt the roots.

For most flowers that bloom from March to September, the fertilization time is mainly from February to April in spring and September to October in autumn, which are just in the growth stage, and the demand for fertilizer is greater, and more fertilization helps to help grow. There are also the months before and after the flowering period, which can ensure the quality and quantity of good flowers, and can also replenish the nutrients consumed. Growth is stagnant during winter dormancy and is not suitable for fertilization.

Summer temperatures are very high, and this is not suitable for fertilization, so you can wait until it is cool before fertilizing.

For flowers that bloom in winter, such as anthurium, junzi orchid, orchid, narcissus, crab claw orchid, etc., these flowers do not stop growing in winter, and they need to be fertilized normally in the winter months.

In addition to ensuring that the fertilization is good for several months, it is also necessary to pay attention to the frequency of fertilization and the fertilization time within a day, and fertilize according to the needs of growth, and the interval can not be too short to prevent root burning. It is best to choose to apply fertilizer around 10 o'clock in the morning during the day, and you can also apply water in the afternoon to promote fertilizer absorption.

Fertilization in spring and autumn: Growing flowers need to be fertilized every 10-20 days. Summer fertilization:

In summer, it is necessary to apply well-rotted organic fertilizer or compound fertilizer once a month. Winter fertilization: At this time the temperature is low, it is best to suspend fertilization.

Precautions: After too much fertilization, you need to water the flowers with plenty of water immediately.

1. Fertilization in spring and autumn

Flowers need sufficient nutrients in the process of growth, when cultivating flowers, you need to apply fertilizer every 10-20 days in spring and autumn every year, you can choose well-rotted cake fertilizer, or superphosphate, to provide the nutrients needed for flowering for the plant, so that the flowering period of the flower is extended.

2. Fertilization in summer

The weather is hot in summer, when breeding flowers in summer, you need to apply a thin rotten organic fertilizer or compound fertilizer once a month, so as to avoid fertilizer damage to the plant, and it is best to choose to fertilize in the morning or evening, and the dormant flowers can not be fertilized in summer.

3. Fertilization in winter

Most of the flowers and plants will enter a dormant state in winter, at this time should not be fertilized, so as not to rot the roots of the plant and die, and for some flowers that bloom in winter, it is necessary to apply a thin phosphorus and potassium fertilizer or diluted urea every half a month to make its flower color more vivid.

4. Precautions

Flowers like fertilizer, but not tolerant of thick fertilizer, when breeding flowers, you need to water a lot of water immediately after too much fertilizer, dilute the fertilizer in the soil, reduce the fertilizer content, so as not to wilt and die of flowers, and then move the plant to a ventilated and dry environment, so that the water in the soil is quickly evaporated.

Organic fertilizer is the amount of use (top dressing), there is no clear limit, generally speaking, the diameter is about 16-18cm, the amount of top dressing is 150-200 grams per time, as the pot increases, the amount of use should also increase.

The frequency of use of fermented organic fertilizer can be once a month, or once every 3 months, and the water-soluble fertilizer is not used diligently enough, try to use fermented organic fertilizer once a month to ensure sufficient fertility.

Note: According to different crops, different rising trends, and different seasons should pay attention to the amount of fertilizer used. It should be watered after fertilization.

As the saying goes, "three points of raising flowers depend on fertilizer and seven points depend on water", in the process of raising flowers, there are many things that need to be paid attention to about fertilization. To raise flowers, you must remember that you can't fertilize these four times, and you regret that you don't know until now! 1. When the flowers are in bloom.

Fertilizing flowers can promote the growth and development of flowers, and will make the stems and leaves of flowers grow faster, but when flowers bloom, do not fertilize flowers anymore, otherwise it is likely to cause the leaves of flowers to grow, fall flowers and buds.

2. When flowers are dormant.

Each flower has its own self-adjustment period, which is the dormancy period of the flower, usually during the summer when the temperature is extremely high. When the flowers enter the dormant period, do not fertilize the flowers, otherwise it is likely to cause too many nutrients in the flowers, resulting in potting soil compaction, and the flowers will also rot roots and yellow leaves and fall flowers.

3. Newly cultivated flowers.

After the flower is transplanted to a new place, it is inevitable that there will be a wound in the root system, and the flower will heal itself within a certain period of time, and this suitable time can not be prematurely fertilized to the flower, otherwise it will cause the flower to be difficult to heal the wound by itself, and eventually wither and die.

4. The leaves of the flowers are yellow.

If you find that the leaves of flowers are yellow, do not rush to fertilize the flowers, there are many reasons for the leaves to turn yellow, such as light, ventilation and watering, etc., the vast majority of leaves are yellowing because of too much watering, water and rotten roots, if this is the reason, then the flowers should be transplanted immediately.

Fertilizer is applied once about 10 days during the growing period.

Generally, fertilization is applied during the growing season of flowers, and vigorous flowers need more fertilizer. Fertilization should be stopped when the flowers are dormant. When the flower seedlings grow, about 10 days to apply a thin fertilizer water, the best effect of fertilization in the evening, avoid fertilization around noon, high soil temperature is easy to hurt the roots.

Organic fertilizer should be fully decomposed before it can be used. The controlled-release fertilizer developed in recent years is very convenient, and it can gradually release Zhihu's long-term nutrient needs with one use.

Pay attention to the following points when fertilizing:

1) Fertilization should pay attention to the type of flowers. Different kinds of flowers have different requirements for fertilizer. For example, osmanthus and camellia like pig manure, and avoid human feces and urine; Rhododendron, camellia, gardenia and other southern flowers avoid alkaline fertilizers; Flowers that need to be re-pruned every year need to increase the proportion of phosphorus and potassium fertilizer to facilitate the germination of new branches; Flowers with foliage as the main focus can be more nitrogen fertilizer; Flowers with large flowers (such as chrysanthemums, dahlias, etc.) need to be applied with an appropriate amount of complete fertilizer during the flowering period to make all the flowers open and beautiful; For flowering flowers, fertilizer and water should be properly controlled during the flowering period, and sufficient complete fertilizer should be applied during the fruit-growing period to achieve the expected effect. bulb flowers, apply more potassium fertilizer to facilitate bulb enrichment; Fragrant flowers, enter the flowering period, apply more phosphorus and potassium fertilizers to promote the fragrance of flowers.

2) Pay attention to the season of fertilization. In winter, the temperature is low, the plant grows slowly, and most flowers are in a state of growth stagnation, and generally no fertilizer is applied; Spring and autumn are in the peak period of flower growth, roots, stems, leaves grow, flower buds differentiation, young fruit swelling, all need more fertilizer, should be appropriate more top dressing; In summer, the temperature is high, the water evaporates quickly, and it is the peak period of flower growth, so the concentration of top dressing should be small, and the number of times can be more.

3) The application of organic fertilizer must be fully decomposed, and raw fertilizer cannot be used. In addition, there are many valuable opinions on how to fertilize potted flowers. For example, the data in Jiangsu and other places pointed out that fertilization should look at the growth, set the dosage, and adhere to the "four more, four less, four no", that is:

Apply more yellow thin, more before germination, more before germination, more before pregnancy, and more after flowering; Less application for growth, less application for germination, less application for flowering, and less application in the rainy season; Don't apply for long, don't apply for new planting, don't apply for summer, don't apply for dormancy. At the same time, it is also pointed out that there are three taboos in potted flower fertilization: one taboo thick fertilizer, two taboo hot fertilizer (high soil temperature at noon in summer, fertilization is easy to hurt the roots), three taboos to sit on fertilizer, when planting flowers, apply base fertilizer at the bottom of the pot, do not put the roots directly on the fertilizer, but add a layer of soil to the fertilizer, and then plant the flowers into the pot.
