Garden soil will be hardened when potted plants, so why is it not hardened in the ground?

After planting a stubble in the field, the ground will be fertilized, and it will only take a long time to plant. How often do you turn your potted plants? Do you also change pots and add soil to move most of them? The difference is huge.

Because the soil in the garden is well drained, it will not harden. If you look at it, if it's a low-lying area with poor drainage, it will definitely harden even in the garden.

The reason for the addition of media is to create a breathable and unobstructed drainage, which prevents soil compaction.

Forehead! There is no such trouble in the countryside! I went out and walked north to the cattle farm and dug up some cow dung! Walk west to the construction site where your neighbor is building a house and dig some sand! Walk east to the side of the road and sweep up some ash from burning corn stalks! The soil for planting flowers is complete!

According to my observation, if the plants in the pot are well maintained, they will not be easy to harden.

It is the problem after you water, it is easy to harden if you are not grounded, loosen the soil, and plug the cracks with soil in watering.

The water and air in the ground are communicative and flowing.

In a large field, the water can flow freely, and the potted plant has a hole at the bottom, and if you are not careful, it will not be waterlogged.

There is still a big difference between crops grown in the ground and potted plants, and it is also impossible to live if you plant the flowers and plants in the garden as vegetables.

Mainly because we usually use tap water at home to irrigate, this water quality is too hard (that is, it contains more minerals, magnesium and sodium, that is, the meaning of water hardness) so that it is easy to promote soil boarding, and the garden is often rainwater or inorganic fertilizer (easy to dissolve in the soil), so compared to tap water, its water quality will be softer and not easy to plate. Usually loosen the soil or add some hydrated lime (which is conducive to the dissolution of water), which will enhance the air permeability of the potted plant.

Because you don't water the ground very often!

Mandarin oranges are oranges in the south, and oranges are oranges in the north.

It should be planted in the soil, and the soil is very fresh.

Water is one thing, the main thing is the temperature difference, and the frozen soil in winter is not compacted.

Flower soil compaction:

1. Apply part of the dry fertilizer on the surface of the potting soil to loosen the soil: loosen the agglomerated soil as much as possible, do not water, and evenly sprinkle the dry fertilizer on the soil the next day.

2. Use soil conditioner or apply microbial agent: The effect of microbial agent is to increase the effective flora in the soil, which can help activate the fixed nutrients in the compacted soil, which can not only make the soil loose but also increase fertility.

3. Increase the air permeability of the compacted soil, and use the "sand pillar method".

Prepare some coarse sand, large grains. Poke a few holes in the potting soil at the edges, preferably deep into the bottom of the pot, insert a thick straw into these holes, pour in coarse sand, and pull the straw out, so that several pillars of sand will form in the pot.

In this way, there will be no watering in the future, and the water will evenly penetrate into the flower soil through the sand column, promoting water absorption and ventilation of flower and plant roots.

Prevention and control methods: 1. Loosen the soil frequently and maintain the air permeability of the potting soil; Watering flowers should be watered slowly with less water, and refuse to wash watering with large water.

2. Be cautious of watering flowers with fresh tap water, and use it after drying the tap water for a few days.

3. Add a flower pot bottom pad to each flower pot, and pour water directly on the bottom pad when watering the flowers, so that the water can pass through the pot bottom to moisten the soil, which has a certain effect on preventing soil compaction.

If the amount of fertilizer is large, the new leaves will shrink and cannot be opened; After 4-5 months, the plant grows larger, the root system is more developed, and the flowers are generally watered once every half a month, and the flowers are more than 20-20-20 water-soluble fertilizer 1000 times. And the number of fertilization is not as frequent as possible, excessive fertilization is easy to produce fertilizer damage, wilting lightly, serious will lead to potted plant yellow leaves and burning roots, long-term excessive fertilization, but also will lead to potting soil back alkali, compaction. The soil structure is not reasonable.

When we pot or repot flowers, we should not only use a single vegetable garden soil, but should prepare loose and breathable soil, which is convenient for the good breathing of plant roots, which is conducive to the growth of flowers and plants. Therefore, in addition to avoiding the choice of clay soil, we can also appropriately add some perlite, coarse river sand or coconut peat to increase the aggregate structure and fluffiness of the soil.

In addition to the large stickiness of the soil itself, which is easy to compact, the compaction of general flower soil is mostly caused by the inactivity of microorganisms in the soil. The compacted soil is not good for orchids, because the orchid roots are aerial roots, and there must be fresh air circulation to be able to grow vigorously. If the culture soil is directly dug into some ordinary pastoral soil, no breathable and permeable medium is added, and organic fertilizer is lacking.

After the soil is potted on flowers, it doesn't take long for it to start to harden, and the root absorption is affected.

Therefore, the choice of soil for planting flowers is very important, the plant is dependent on the soil environment of the root system to survive, the environment is comfortable, the root system is strong, the branches and leaves grow well, only the healthy growth of the plant can give birth to flower buds and flowers, it can be seen that the choice of soil is very important for planting flowers. After a period of maintenance, the fertility of the soil will decline, and there will be compaction, so the soil we choose to maintain plants must be diversified, and it is recommended that you can choose nutrient soil and granular soil or choose pine needle soil and humus soil to maintain plants. The chemical components such as chlorine and bleaching powder contained in tap water are easy to make the potting soil compact, so it is necessary to water the flowers after drying and precipitating.

If conditions permit, it is better to use natural soft water such as rainwater, river water, river water, and freshwater lake water to water flowers.

Regular loosening of the soil will reduce this situation, and you can also change the plant to a new pot of soil, which can solve this problem.

In such a situation, I think we should spray pesticides in time, and we should also choose grafting, or we can choose to change some soil properties with better properties.

In such a situation, we can actually loosen the soil and water it a little. Loosen the soil again.

Everyone basically uses potted plants to breed flowers and plants, basically everyone knows that the soil in the potted plant is easy to compact, and the soil will affect the growth of plants after compaction.

Watering. Everyone basically uses tap water to water plants directly, and we all know that tap water is hard water, which contains a lot of nitrogen, and if you use tap water to water plants for a long time, it is easy to make the potting soil compact. Therefore, if you use tap water, it is best to dry it for about 2 days before the nitrogen volatilizes before using it, or it is best to use rainwater or river water directly.

Fertilize. The growth of plants needs sufficient nutrients, and there are many people who will learn to water the plants on the Internet, such as washing rice water, overnight tea, etc., but these are not decomposed, and it is impossible for the plants to absorb the fertilizer directly, so it will make the soil compact.

Adding some organic fertilizer to the soil can alleviate the effect of soil compaction and increase the nutrients of the soil. You can also remove the soil on the surface of the potting soil, and then grind the organic fertilizer into powder, sprinkle it directly into the potted plant, and water it when the soil is short of water, so that the plant will slowly accept nutrients and promote the growth of the plant.

First of all, the potting soil is loosened, one day is not watered, and the next day it will be dried with fertilizer (powder.

DAO) evenly sprinkled on the surface of the potting soil; The amount of fertilizer should be determined according to the size of the pot, usually 10-15g in large pots, and 10g in small pots to prevent excessive fertilization and heat to burn the plants; After fertilization, water is sprinkled in the pot once to make the potting soil and dry fertilizer tightly combined, and then fertilized every month or so, and the soil will gradually loosen about 20 days after fertilization.

Measures to prevent soil compaction:

1. Use tap water with caution.

Fresh tap water contains a certain amount of bleaching powder and chlorine, which are the main factors causing potting soil to compaction, and it is best to store them before watering to reduce their content.

2. Loosen the soil in time.

Loose potting soil should be done in a timely manner, especially after heavy rain. Loosening soil not only keeps the potting soil breathable, but also improves the absorption capacity of the plant's roots.

3. Use less chemical fertilizers.

Plant fertilization is best to use organic fertilizer after decay, fermentation, and disinfection, and the organic fertilizer will adjust a certain void for the plant in the decomposition process, improve soil air permeability, and play a loose role.

1. Different plants use different soils, in order to avoid potting soil compaction and affect plant growth, we can choose to add some medium to the soil, which can add bark, sawdust, vermiculite, ceramsite, etc. This not only increases the air permeability and water permeability of the soil, but also prevents soil compaction.

2. In order to avoid soil compaction, this small method can loosen the soil regularly, this small method is very simple. Usually we will also loosen the soil for plants when planting flowers and plants, so as to effectively avoid potting soil compaction, if you find that the potting soil has been compacted, you should pay attention to loosening the soil. It is best to choose regular loosening of the soil so that it does not show the phenomenon of compaction.

3. Use less chemical fertilizers, in daily planting, we will choose to use chemical fertilizers to increase nutrition. However, chemical fertilizers can cause soil compaction. Organic fertilizers can be properly selected, and the husk and peel can not only provide nutrients to the plants slowly, but also loosen the soil and the soil will not be compacted.

4. The plant soil that is commonly watered with tap water will have the phenomenon of compaction, because there are a variety of substances in the tap water, if it is often used, it may form potting soil compaction, there is a small way to be very effective, you can choose to use tap water, but you need to put it in the sun. Or store it for a day in use. In this way, soil compaction can be effectively controlled.

Potting soil compaction, one is the hardness of the water used for watering flowers, that is, it contains more calcium and magnesium ions, and these water-insoluble compounds gather in the potting soil, making the potting soil hard and compacted. The second is the improper use of chemical fertilizers, such as the soil containing more calcium, the application of ammonium sulfate will cause the potting soil to condense. In addition, some people like to use soy milk, milk, and egg whites to water flowers, this unfermented protein, not only can not be absorbed by plants, but also causes soil compaction.

Potting soil compaction should generally be replaced, in addition to the usual watering water, to dry for a few days before use. And be diligent in loosening the soil. In addition, it is necessary to have the right way to water.

1. Padding pot watering method Contrary to the ordinary watering method, put the pot into a larger clear water basin to make the water moisten the soil through the bottom of the pot, which is beneficial to prevent soil compaction and has certain benefits for root development, but the salt in the soil will rise with the water and accumulate on the surface of the soil and the edge of the pot, which is easy to damage the nearby rhizomes. Therefore, the watering of potted flowers should be carried out alternately by two methods: pad pot watering and ordinary watering.

2. Sand pillar watering method When potting or changing pots of flowers, first insert a few hollow bamboo tubes or metal pipes in the empty pot, then fill the soil and compact, then fill the empty pipe pipe with coarse sand, and finally pull out the empty pipe, and form a sand pillar in the pot. The number of sand pillars set depends on the size of the pot. Later, only water at the sand pillar, so that the water spreads evenly to the surrounding potting soil through the sand column, which can avoid soil compaction and has no effect on plant growth.

The soil in the pot is still being shoveled? Let's take a look at the right solution and avoid detours.

Raising flowers will inevitably encounter soil compaction, and if you use these kinds of water well, you will not encounter hard compaction.

The cause of soil compaction is that plants lack oxygen, which hinders the respiration of roots.

Soil compaction refers to the phenomenon that the soil surface layer is damaged and the soil material is dispersed under the action of external factors such as irrigation or rainfall due to the lack of organic matter and poor structure, and the soil surface becomes hard by the cohesive force after drying. To put it simply, our common potting soil is agglomerate, hardened, and prone to cracking as soon as it dries.

The lack of organic matter in the soil will affect and reduce the formation of soil aggregate structure, which will lead to soil compaction! Soil aggregate structure is a soil structure in which several soil grains are bonded together to form aggregates.

Because the small pores between the single grains and the large pores between the aggregates are formed, the small pores can retain water, and the large pores can maintain aeration, and the aggregates allow the soil to ensure the good growth of plant roots, which is suitable for crop cultivation. Therefore, the soil with aggregate structure has a good growth of water vapor, nutrients and accumulation, which is more conducive to the growth of plant roots, and is an important guarantee for the vigorous growth of flowers.

What are the main hazards of soil compaction:

1. Root system ability declines.

In the case of soil compaction, the lack of oxygen leads to a decrease in root activity, can not develop normally, plant root cell respiration is weakened, and nitrogen and other nutrients exist in an ionic state, and the energy produced by cell metabolism is consumed during absorption, and respiration is weakened, so the energy is insufficient, affecting the absorption of nutrients.

2. Cause nutrient deficiency.

Deficiency is not necessarily caused by the lack of this element in the soil, but by a series of problems such as soil compaction, unsuitable soil pH, or unbalanced soil moisture.
