Diagnosis: potted flowers raised a few years from the rich handsome short poor how to do?

Q: I have been growing potted flowers on my balcony for three years, and they have been in good condition all the time, and they blossom and bear fruit normally. Recently, however, the state seems to be getting worse and worse, with yellow leaves, thin branches, small flowers and small fruits, and so on.

Chief, what's going on? What should I do with it?

Well, this is a common state of balcony planting.

The principle is simple: potted flowers are limited by specific environmental conditions, and when the potted soil cannot maintain the normal growth of flowers, the state described by Taiyou "whether Lu is fat or not" will appear, thus reducing the ornamental value.

Director: how to deal with it? Changing the basin and soil is the best way.

Taiwan friend "is Lu fat": OK, I'll change the basin right away.

Hey, wait a minute, let the director finish first. The balcony is limited, and it is not a long-term solution to change the basin. Aah!

This, this. Then fertilize it!

However, before fertilization, the types and methods of fertilizer should be determined according to the variety of flowers, habits, the purpose of fertilization and the missing elements.

The commonly used fertilizers for potted flowers are divided into two categories: organic fertilizer and inorganic fertilizer.

Organic fertilizer is made from the remains of animals and plants after decay and fermentation.

Organic fertilizer, also known as complete fertilizer, contains not only nitrogen, phosphorus and potassium, which are needed for the growth and development of flowers, but also a large number of other elements, trace elements and growth stimulating substances, in which a large amount of organic matter is decomposed to produce organic acids, which can dissolve insoluble fertilizers such as calcium phosphate.

Humus in organic matter can improve soil structure, increase soil fertility, water retention and permeability, as well as long-term and soft fertilizer effect.

However, the fertilizer efficiency of organic fertilizer is slow, the source is difficult, and the processing is also troublesome.

Organic fertilizer is usually divided into animal organic fertilizer and plant organic fertilizer.

Animal organic fertilizer, such as human feces and urine, livestock dung, feathers, hoof horns, bone meal, fish eggs and other household waste.

Plant organic fertilizer, such as bean cake and other cake fertilizer, sesame sauce residue, leaf weeds, green manure, Chinese herbal medicine residue and so on.

In the above two kinds of organic fertilizers, the contents of nitrogen, phosphorus and potassium in animal fertilizers are usually higher than those in plant fertilizers, and the fertilizer effect is longer; plant fertilizers are soft.

Their common characteristics are: at any time and any application method, it must be fully fermented and decomposed to be applied when there is no stench.

Otherwise, not only can not play the role of fertilization, but also "burn roots", affecting the normal growth of flowers.

Inorganic fertilizer mainly refers to commercial chemical fertilizer.

For example, urea, ammonium sulfate, calcium superphosphate and so on. Plant ash is a kind of natural inorganic fertilizer. Inorganic fertilizer has the characteristics of simple fertilizer content, fast fertilizer effect, non-lasting, easy loss and so on, which is easy to cause short-term overgrowth of potted flowers, and the dosage is not easy to master. If the concentration is not appropriate in potted flowers, it often leads to plant death.

The types of inorganic fertilizers are as follows:

Nitrogen fertilizer: urea, ammonium sulfate, ammonium chloride, ammonium nitrate and so on.

Phosphate fertilizer: calcium superphosphate, phosphate rock powder, etc.

Potash fertilizer: potassium chloride, potassium sulfate and so on. Potassium dihydrogen phosphate is a high efficient phosphate and potassium fertilizer.

In the process of flower fertilization, organic fertilizer and inorganic fertilizer have their own advantages and disadvantages. We should give full play to our strengths and circumvent our weaknesses, cooperate with each other and use them alternately.

Er, the specific method of alternative fertilization, let's go on to explain the next article. That's all for this article. If you have any questions, sign in in the message area below.
