How to fertilize flowers and potted plants reasonably? Fertilization Points and Points for Attention in Flower Viewing and Bonsai

How to fertilize the bonsai? Fertilization is indispensable in the whole process of daily maintenance of flowers, and only by applying fertilizer skillfully can flowers grow exuberantly and develop well. Below we introduce the fertilizers and fertilization methods commonly used in flower maintenance.

1. How to achieve reasonable fertilization?

Rational fertilization is to pay attention to timely and appropriate amount of fertilization. Timely means that flowers need to be fertilized only when they are needed. The index of fertilization is to find that the growth of flower plants is weak and the leaf color becomes lighter. As for when and what fertilizer should be applied, it depends on the different growth and development periods of different flowers.

How to apply the right amount of fertilizer? It is best to apply more nitrogen fertilizer at seedling stage to promote seedling growth; to apply more phosphate fertilizer at bud stage to promote large flowers and seeds; and to control the amount of fertilizer application at the early stage of fruit setting. To sum up, no matter when to apply fertilizer, we should pay attention to the amount of fertilization. if there is too much nitrogen fertilizer, the plant is easy to grow; too much potash fertilizer will hinder the growth of flowers and affect their flowering and fruiting.

two。 What are the principles of rational fertilization?

The main results are as follows: (1) different kinds of flowers have different requirements for fertilizer. Foliage-based flowers can pay more attention to nitrogen fertilizer; flowering flowers need to apply appropriate amount of fertilizer during flowering period; fruit-viewing flowers should properly control fertilizer and water quantity during flowering stage and apply sufficient fertilizer in strong fruit stage in order to achieve the desired effect.

(2) fertilization changes with different seasons, the temperature is low in winter, the growth of flowers and plants is slow, generally do not apply fertilizer; flowers in spring and autumn are in the peak growth season, the amount of topdressing fertilizer should be increased appropriately; the temperature is the highest in summer and the water evaporates fast. most flowers are in the peak period of growth, the number of times of chasing the moon is increased, and the concentration should be low.

(3) the application of organic fertilizer is the most taboo to apply unrotten fertilizer, which must be fully mature before it can be applied.

3. Why can't unripe fertilizer be applied?

Some flower lovers often bury some eggshells, animal offal, cake fertilizer, raw horse dung and so on. In this way to increase the nutrients of the soil, the result is counterproductive, not only did not achieve the desired goal, but hurt the flowers. The reason is that in the process of flower growth, it is necessary to absorb nitrogen, phosphorus, potassium, magnesium and other nutrient elements dissolved in water by fermentation in the soil. The spoiled food or some animal manure added to the basin soil is directly buried in the human basin without fermentation. when it is decomposed by water and fermented, it will produce high temperature, directly scald the flower root system, coupled with the activity of microorganisms, so that the soil is seriously anoxic, resulting in the death of flowers. At the same time, when the immature fertilizer is fermented, it will produce a bad smell, which can easily lead to flies laying eggs, maggots easily bite the root system, and it is necessary to apply fully mature fertilizer to ensure the good growth of flowers.

4. What are the benefits of extra-root fertilization?

The most significant advantage of extra-root topdressing is that it can quickly play a significant fertilizer effect with less fertilizer, and the fertilizer will not be fixed and not affected by the absorption function of the root system. In general, after spraying inorganic fertilizer on the leaf, it can be absorbed in 5 hours. The fertilizer effect can last for 7-lo days, so extra-root topdressing should be sprayed every 7-10 days. Extra-root topdressing can be carried out at all growth stages except the flowering stage.

5. What matters should be paid attention to when applying fertilizer outside the root?

The main results are as follows: (1) not any kind of fertilizer can be used as extra-root topdressing, only some fertilizers with good solubility can be used as extra-root topdressing.

(2) the concentration of fertilizer was relatively low during extra-root topdressing. For example, the concentration of ferrous sulfate is 0.2% Mel 0.5%, the concentration of SSP is 1% Mel 3%, the concentration of urea spraying should not exceed 0.1%, and so on.

(3) generally choose morning or sunny and windless weather for extra-root topdressing. The most suitable time is after 3: 00 p.m. to 4: 00 p.m. Do not apply fertilizer at noon, so as not to burn the leaves.

(4) spray the foliar surface as evenly as possible, because the back of the leaf contains a large number of stomata and absorbs faster than the foliar surface, and the back of the leaf is best sprayed to the fertilizer solution. The amount of spraying can make the leaf surface moist.

(5) the fertilizer must be dissolved evenly and the insoluble matter must be filtered out. Sometimes you can use fungicides and pesticides? Kunming is used to prevent diseases and insect pests in a two-pronged way.

Matters needing attention in fertilization of bonsai flowers

Bonsai

Bonsai flowers should be fertilized mainly by organic fertilizer, combined with chemical fertilizer. The following points should be paid attention to when applying:

1. Organic fertilizer is mainly used before transplanting or changing basin base fertilizer, which should be fully mature.

2. No matter chemical fertilizer is used as base fertilizer or topdressing fertilizer, it is necessary to prevent excessive fertilization. In general, the amount of nitrogen (N) applied in 1kg soil can be estimated by the amount of nitrogen fertilizer or compound fertilizer. According to the specification and plant size of the pot, usually 10-30 grains of compound fertilizer are applied each time.

3. When applying fertilizer, chemical fertilizer should not be placed at the base of the root to avoid burning the root and is not conducive to absorption; fertilizer should be applied to the edge of the basin; do not spread fertilizer on the leaf surface to prevent burning leaves.

4. In the event of a fertilizer burn accident, water or change the basin in time, and replace part or most of the basin soil with new soil.

Key points for maintenance of bonsai in autumn and matters needing attention in fertilization

Autumn is the season when all things begin to wither. the general characteristic of tree growth in autumn is that the spring and summer shoots have become Lignification, and a new root and leaf system has been formed, which increases the assimilation area of trees and accumulates nutrients for autumn shoot and flower bud differentiation. The autumn shoot growth and flower bud differentiation of evergreen trees are carried out at the same time, the competition for nutrient distribution is fierce, vegetative growth is better than reproductive growth, reproductive growth consumption is greater than vegetative growth, and can inhibit each other.

If the nutrition accumulation in autumn is not sufficient, the autumn shoot can not be lignified, there will be fewer flowers and fruits in the coming year. The new and old branches that are not lignified must undergo the test of severe winter, and the test of plants in severe winter is more cruel than that of hot heat, so autumn must create conditions for bonsai trees to survive the winter, promote their early autumn buds, prolong their growth time, and speed up their growth. Fully accumulate nutrients to help them survive the winter smoothly. In autumn, the stump germinates late, the growth time is shortened, the nutrient accumulation is insufficient, the branchlets are not lignified, the old and weak branches and inner branches do not accumulate enough nutrients, and the overwintering branches are easy to shrink and wither. (this is especially true of newly planted pile bonsai.)

Therefore, the management of autumn bonsai is an important period, and soil, water, fertilizer and light should be strengthened. Evergreen trees should also pick their hearts to promote the Lignification of autumn branches as soon as possible so as to create conditions for overwintering. Conifers and deciduous trees sprout but not sprout in autumn, so it is necessary to promote their dormancy in late autumn so as not to waste nutrients and affect their smooth overwintering.

Main points of maintenance and management of bonsai in autumn: 1. Illumination: bonsai plants and trees should strengthen the light in autumn and put the pot in the place of full sunlight, which is beneficial for trees to accumulate nutrients, take root and grow leaves, blossom and bear fruit.

2. Basin soil: the soil should be dry and wet alternately and poured thoroughly. Usually loosen the soil, let the air seep in, and increase the air content in the soil. The basin soil is dry and wet alternately, when the soil is dry, there is little moisture in the soil, the air can penetrate into the space filled with water, and the root breathes smoothly. Proper drying can promote the growth of roots, facilitate the development of autumn shoots, and form leaflets.

3. Fertilization: fertilizer should be timely and appropriate, and should be applied many times in early autumn. (potted friends can use jade fertilizer conveniently, hygienic, without any unpleasant smell and sufficient fertility) less fertilizer should be applied in the Mid-Autumn Festival, and fertilization should be controlled in late autumn so as not to promote late autumn shoots. This use of fertilizer can promote early growth of autumn shoots, so that vegetative growth and reproductive growth are carried out at the same time, and there will be many leaves and flowers and fruits in the coming year. If the tree is in good condition and there is more autumn fertilizer, spring flowers may bloom in autumn. My black persimmon and Luohansong have spring flowers and autumn blossoms and autumn fruits for many times. Early application of autumn fertilizer is widely used in fruit production, but tree stump management is more precise, so autumn fertilizer should be applied early.

How to fertilize bonsai? Generally thin fertilizer is applied frequently: (1) pomegranate, begonia, wisteria, Pyracantha, Phyllostachys pubescens and other flowers and bonsai should be applied more phosphorus and potash fertilizer. (2) five-needle pine, yellow poplar pile, ivy and other foliage bonsai should be based on nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. (3) Pine and cypress bonsai, can be self-made bean cake cooked water diluted fertilizer, 3 times a year. (4) fertilization can be applied in spring, summer and autumn, and stop in winter dormancy. (5) trees that have just come into the pot cannot be fertilized because their new roots have not yet grown. (6) liquid fertilizer should not be too thick and must be diluted before it can be used, otherwise it will cause fertilizer damage. (7) Organic fertilizer and cake fertilizer must be fully mature before they can be used, otherwise they will ferment in the basin soil to produce high temperature and burn the roots. (8) do not sprinkle liquid fertilizer and water as topdressing on the leaves. (9) fertilization is good in sunny days, but not in rainy days and plum rain seasons. 4. Pruning: the top advantage is obvious during the growth of bonsai plants and trees. Under the condition of good soil, fertilizer, water and phosgene, the growth is exuberant, the shape proportion of bonsai is deformed and expanded in autumn shoot growth, and the leaves are concentrated to the edge. The distribution of nutrients is also uneven, and the supply of nutrients on the old branches and central branches is insufficient, which is intended to die in winter. Autumn shoot and spring will also sprout at the top, become bigger, lose the center of gravity, break the composition proportion of bonsai, and become not very beautiful. Therefore, before the formation and growth of autumn buds, thinning and shearing should be carried out, and the coring of autumn shoots should be removed after the growth of autumn shoots, so as to overcome the top advantage, restrain and combine, distribute nutrients reasonably and maintain a good growth trend.
