Are there any ornamental plants at home that don t need to be planted in soil?

Air pineapples: They can hang directly in the air and survive by absorbing moisture and nutrients from the air on the scales on the leaves. The flowers are particularly beautiful and flexible.

Fuguizhu: I have raised this flower, you can keep it in a vase, as long as you keep the water fresh, you can continue to hydroponics.

You can choose hydroponic plants, copper coin grass, pothos, white palm, anthurium can all be hydroponic. It is easy to raise evergreen in all seasons, as long as it is not too cold indoors in winter, it can be raised very well.

There are many hydroponic plants, such as narcissus, copper coin grass, Guanyin bamboo, transfer bamboo, rich bamboo, bamboo, anthurium, bulb orchid and so on.

Summary. The plant camellia, lily which the soil can grow. Bird of paradise, jasmine.

The plant camellia, lily which the soil can grow. Bird of paradise, jasmine.

1. Camellia: likes acidic soil and is suitable for planting with fertile and loose loam. 2. Lily bamboo:

Agave plants, prefer warm environments, and have low soil requirements. 3. Bird of paradise: a perennial herbaceous plant with oblong-lanceolate leaves.

Loam-loving. 4. Jasmine: The plant height is about 3 meters, and the flowering period is in May every year. Moon Flower: Known as the queen of flowers, it grows luxuriantly in fertile loam soils.

At the beginning, it is better to use ordinary soil, which is too nutritious, which not only destroys the soil environment, but also affects the normal nutrient needs of plants.

Soil is the main source of water and nutrients for plants. Potted flowers, due to the limited volume of the pot, can only hold a small amount of soil, so the requirements for potting soil need to be more particular. In general, the potting soil should be moist, but not waterlogged, which is not only aeration and permeability, but also retains water and fertilizer.

Due to the wide variety and different traits of potted flowers, they also have different soil requirements.

Many flowers are sensitive to the pH of the soil. Such as rhododendron, camellia, white orchid, jasmine, etc., all require acidic soil. When the soil reacts alkalinely, these flowers will turn yellow and lose their leaves, or even die.

Under alkaline conditions, plants produce "yellowing disease" due to physiological iron deficiency, so strong concentrations of ferrous sulfate should be sprayed in time, and potting soil should be replaced if necessary. Plants such as cacti and bamboos like alkaline soil, so some lime or rice bran ash should be added to the potting soil. Hydrangeas are blue in alkaline soils and red in acidic soils.

There are also some more adaptable, such as chrysanthemum, caryophyllus, yueji, plum blossom, etc., which can grow normally in slightly acidic to slightly alkaline soil.

After long-term watering, the potting soil will alkalize and harden, so it is necessary to replace the potting soil every two or three years. Different varieties and types of the same species of plants have different requirements for soil pH. For example, the terrestrial cactus and cactus balls in the cactus plant require drainage and aeration of calcareous alkaline soil, while the epiphytic types such as epiphyllum and lingjian lotus require shade of moist and drained neutral or slightly acidic soil.

The soils commonly used to prepare potting soils are humus, peat, coniferous, swamp and dung beds, which are rich in humus. Compost soil, clay soil, turf soil, etc., are rich in minerals.

Specifically, humus soil is made by accumulating and rotting the fallen leaves of broad-leaved trees, and is suitable for potted begonias, cyclamen, etc. The turf soil is suitable for the cultivation of roses, caryophyllus, etc. Coniferous soil is formed by the accumulation and decay of deciduous branches of conifers and fresh mosses, which is strongly acidic, and is the most suitable for cultivating rhododendrons.

Marsh soil is the upper layer of soil on the edge of ponds and marshes and dry swamps, and is suitable for the cultivation of conifers, masts, etc., by adding river sand or mixing with other soils. The sandy soil is suitable for the growth of palm and cactus plants. Sphagnum moss, purple root and water keel root are indispensable materials for the cultivation of tropical orchid, bromeliads and Araceae.

Stones and gravel can be placed under the pot to facilitate soil aeration and drainage. Generally, when cultivating, a simple one is rarely used, and it is usually prepared with a mixture of several soils. Recommended Reading:

In addition to planting succulents, sandy soil is also suitable for planting such as peanuts, soybeans, fruit trees, cistanche, rhino horn, aloe vera, Peruvian Tianlun column, centenarian, Mongolian sand holly, Cistanche tubular, green bell, golden amber, red skin sand jujube, raw stone flower, caragana intermediate, salt cistanche, cactus, white thorn, sand jujube, giant pillar, sand jujube, licorice, single tree, flower stick, Xinjiang sand holly, Hexi chrysanthemum, red skin sand jujube, short spike willow, purple rod willow, sea buckthorn, spotted brocade variation, long spike willow, shallot, Hexi chrysanthemum, Buddha belly tree, white hemp, desert rose, Luobuma, Populus euphratica, H. saxono, naked fruit tree, spotted rhino horn and Chinese medicinal materials. These are relatively drought-tolerant sandy plants.

Sandy soils are divided into four categories: sandy soil, hemorrhoidal thin and heavy soil, low-lying saline-alkali soil, and humus soil. According to its characteristics, plants are the most suitable for planting.

1) Sandy soil: generally the particles are scattered, the soil is loose, the aeration ability is strong, but the lack of organic matter, the evaporation is large, and the water retention performance is low. According to these characteristics, it can be arranged to plant Beisha Shen, Lingruo, Wang Buliuxing, Cassia Seed, etc.

2) Thin and heavy soil: generally lack of organic matter, cohesion occlusion, poor permeability, muddy when wet, and hardened when dry. This kind of soil is not suitable for planting medicinal herbs.

After improvement, we can consider planting some deep-rooted arbor medicinal materials, such as Phellodendron chinensis, Eucommia ulmoides, Magnolia officinalis, andXin Yi and so on. Pity.

3) Low-lying saline-alkali soil: contains more salt, and the acid-base reaction is at pH value of 75 Above, such soil should be deeply turned into the fort, more organic fertilizer should be applied, increase the drainage and irrigation capacity, and improve the physical and chemical properties of the soil.

It is mostly suitable for the cultivation of medicinal materials such as ceremonies, ephedra, licorice, Huangmao, and Huiba.

4) Humus soil: deep soil, loose soil, fertile, containing more organic matter, good physical and chemical properties, but also more water and fertilizer retention. This kind of soil is suitable for the growth of various plants, and can arrange the planting of a variety of medicinal materials such as Platycodon, Radix Radix, Atractylodes, Atractylodes, Banxia, Shegan, and Red Mast.

It is also suitable for cultivating woody medicinal herbs.

What plants to plant need to see.

soil, but first we need to lookThe pH of the soil

The pH range is 0 to 14, according to the pH from small to large acidic, neutral and alkaline, pH value of 7 indicates that the soil is neutral, less than 7 is acidic, and greater than 7 is alkaline.

Plants can grow normally in a wide range, but each plant has its own suitable pH. For example, the suitable range of soil pH for apples is , and the optimal range is . When the pH value of the soil exceeds the optimal range, the growth of plants is stunted and stunted as the pH value increases or decreases.

Most plants struggle to grow at a pH > or ".

Soil pH also has a great influence on the availability of nutrients, such as the availability of phosphorus in neutral soil; Alkaline soils have poor availability of trace elements (manganese, copper, zinc, etc.).

China divides the pH of soil into five grades: strong acidic soil (pH less than 5), acidic soil (neutral soil (alkaline soil (strong alkaline soil (pH greater than.

The soil in the mountain forest, the humus of the ravine, is generally black or brown soil, relatively loose, fertile, good permeability, and is a very good acidic humus. Such as: pine needle humus, peat, humus, etc.

Acidic soils are generally darker in color and mostly black-brown, while alkaline soils are mostly light-colored in color such as white and yellow. In some saline-alkali areas, there is often a white layer of saline-alkali on the soil surface.

There are 3 ways to arrange culture soil at home.

First, it should be loose, drained and breathable to meet the needs of root respiration;

Second, it should be full of nutrients, rich in humus, good fertilizer and water retention, and meet the needs of flower growth and flowering;

Third, it should be suitable for the pH of flower growth; Fourth, it should be free of harmful microorganisms and insect eggs, living organisms and other harmful substances. It is difficult to find soil that fully meets the above requirements in nature, and if you want to raise flowers well, it is necessary to artificially prepare and cultivate soil according to the ecological habits of flowers and the requirements of each stage of growth and development.

8 types of soils commonly used for home flower raising:

1. Humus:

Also known as manure soil. It is made by fermentation of a mixture of livestock manure, bedding and feed residues, containing a variety of organic matter and nitrogen, phosphorus, potassium, etc. Its composition is mainly composed of humus, loose texture, acidic, rich in nutrients, strong fertilizer and water retention, but poor drainage.

2. Saprophyll:

It is the topsoil of the forest area in nature, which is formed by the accumulation and decay of fallen leaves over the years. The humus soil is loose, porous, acidic or slightly acidic, rich in nutrients, suitable for planting a variety of acid-loving soil flowers, and is also one of the main materials for preparing potted flower culture soil.

3. Peaty soil:

It is called peaty soil, which is collected from peat bogs. It is formed by the continuous accumulation of organic matter or under flooded conditions, some of which have been carbonized, black-brown in color, acidic, rich in organic matter, some up to 80%-90%, which can improve the physical properties of the soil. The peat soil itself does not have many nutrients for plants to absorb and utilize, but it contains a large amount of fiber and humic acid, and has a strong ability to absorb fertilizer and retain water, so it is a good material for preparing flower culture soil.

4. Turf soil:

It is made by weeds, straw, etc. mixed with animal manure and other accumulation and decay, containing more humus, and containing more minerals, which is weakly acidic.

5. Coniferous soil:

It is formed by the accumulation of deciduous stumps and bryophytes of conifers of the pine family and cypress family. The coniferous soil formed by the deciduous leaves of the spruce genus and fir genus is acidic (, rich in humus, and suitable for acid-loving soil flowers.

6. Mountain mud: commonly known as orchid soil, it is a natural humus produced in the mountainous areas of Jiangsu and Zhejiang, which is formed by the decay of fallen leaves accumulated over the years. Its color is black and brown, loose, light in weight, not only breathable, drainage, but also fertilizer and water retention, is a good potted soil. This soil is acidic, which is suitable for cultivating flowers that love acidic soil.

7. Somen sandy soil:

It is a kind of fine-faced sandy soil, with pure texture, good aeration and water permeability, but no fertility, no aggregate structure, and poor water retention performance. It is often used as soil for sowing or cuttings of general flowers, and it is also one of the raw materials for preparing culture soil.

8. Guangdong Tangni:

It is a fertile pond mud mound in South China, which is a topsoil deposited at the bottom of the pond for many years, rich in organic matter, sufficient nutrients, slightly acidic, and hard in texture. In addition, there are also lake soil, river mud, garden soil, field soil, slag soil, horse manure soil, etc.

Acid-tolerant plants, you should be wondering what plants are out there, right?

Quercus chinensis, chestnut, noodle sheepflower, bayberry, tea tree, masson pine, cedar, stone pine, etc. are all acid-tolerant plants.

What soil is suitable for potted flowers and plants, and how to prevent and improve soil compaction?

Plant growth also has two parts: respiration and photosynthesis. Respiration works like humans, absorbing oxygen, exhaling carbon dioxide, and consuming glucose to convert into energy for life. Photosynthesis, on the other hand, is the process of synthesizing glucose from chlorophyll in plants in the presence of light.

That is to say, plants rely on light (sunlight) as a medium to provide themselves with nutrients - glucose. Therefore, green plants are inseparable from photosynthesis. And what we say is that there is more oxygen in places where plants are abundant because:

During the day, photosynthesis is greater than respiration. At night, the rate of respiration also slows down due to the lower temperature. Overall, plants provide oxygen to the atmosphere.

But as far as specific plants are concerned, there are also light-loving and shade-loving ones. Trees in general (taller trees) like a lot of light, and it can also be seen from their physiological characteristics - growing tall can meet more sunlight; Some shrubs and herbaceous plants (such as bamboo) are shade-loving and have relatively low requirements for light. This is also a natural evolution over a long period of time (dwarf plants in the forest grow in the shade of trees for a long time).
