What are the wind resistant and salinity resistant plants?

Sand pine grass, tamarix, purple locust.

Salinity-resistant plants include: Tamarix, S. spp., Acacia purpurea, etc.

Tamarix: Also known as Sanchun willow, its dry red branches are soft, the flower color is beautiful and the group finger has a long flowering period. The willow is a willow, named because its leaves are slender and drooping, and they flutter in the wind like a pomegranate branch.

Shapon grass: also known as rat sting. It has always been a barrier for wind prevention and sand fixation in the coastal area of Jinjiang.

Purple locust: also known as locust, purple locust, leguminous locust genus, is an excellent green manure and stem strip woody plant Purple locust is sensitive to land requirements or tung is not strict, salt and alkali resistance, barren resistance, drought resistance, waterlogging resistance, cold resistance, sand pressure resistance, strong stress resistance, developed root system, and has a strong resistance to disease, insects, smoke and pollution.

Casuarinas, Acacia taiwanensis, Wetland pine, Japanese black pine, Pinus sylvestris, Arborvitae orientalis, fast-growing white wax, white elm, golden-leaved elm, pentagonal maple, neem, luan, pawy, acacia, alba, black locust, soft jujube, papaya, cog, torch tree, salina wood, sand date, sea buckthorn, hibiscus, forsythia, white thorn bush, four-winged quinoa, sandy cypress, tamarix, golden-leaved dwarf, willow, bamboo, maran, daylily, phlox.

When the soil contains more salt (generally exceeded, most plants will not grow normally; However, some plants can survive well, and some of them even have to grow in the soil with a high salt content, and they cannot survive without the saline soil, and this kind of plant is called halophytes; Others grow well on non-saline soils, and can grow normally on saline soils; These plants that can grow normally on saline soils are called salt-tolerant plants.

Problem description: Analysis: Morphologically, these plants are short, dry and hard, the leaves are underdeveloped, the transpiration area is reduced, the stomata are sunken, the epidermis has a thick outer skin, and often has grayish-white hairs.

In terms of internal structure, the intercellular space is small, the palisade organization is developed, some have fleshy leaves, and there are special water-storing cells, which can prevent the assimilated cells from being damaged by high concentrations of salt.

Physiologically, it has a series of salt-resistant characteristics, and according to the adaptation characteristics to excess salts, it can be divided into poly-salt plants, salt-secreting plants, and impermeable plants.

The protoplasm of polysaline plants is particularly tolerant of salt, and they have very high cell concentrations that absorb water from high concentrations of soil solutions, such as Halophylla.

Halophytic plants can drain the excess salt absorbed into it through the dense salt glands on the surface of the stems and leaves, and then be washed away by the wind and rain, such as mangrove plants.

Salt-impervious plant cells are very impermeable to salts, they absorb little or no salt from the soil, and they also improve the plant's ability to absorb water from the soil.

In the construction of new greening, wind-resistant tree species such as camphor, purple-leaved barberry, and boxwood are mostly used, and most of these tree species have withstood strong winds due to deep roots or short trunks. In addition, magnolia and ginkgo biloba, which are commonly found in the park's landscape trees, are also wind-resistant tree species.

Situation in Hainan:

Resistant to salt and alkali, humidity and shade.

Sea Wind Resistant Seedlings:

Mulberry, Mulberry petalless, Autumn eggplant, Morinda officinalis, Lemon fruit, Olive Tree, Silver-leaved tree, Grass Tung Tree, Manjusri orchid, Lotus leaf tung, Jade. Hama Yurui. Water yellow bark, water coconut, hibiscus, hibiscus, single-leaved vitex, salty chrysanthemum, etc.

Cinctus chinensis has deep roots and strong wind resistance. Coptis chinensis.

Salt-secreting plants - petal scale flowers, mangroves.

There are many plants in the world that can tolerate salinity such as mangroves. Plants such as Populus euphratica and petal scale flower are very resistant to salinity. They can grow in saline-alkali soil with a high salt content, and the best way to resist salinity is to secrete salt

Although they inhale a large amount of salt, it does not accumulate in the body, but continuously excretes the salt, along with water, from the salt glands on the surface.

Thin salt plants - wheat, barley: There is also a "thin salt plant", their resistance to salinity is to absorb a lot of water to dilute the salt, such as wheat, barley and other crops.

Poly-salt plants - Salisa salsa, Suaeda salsa: "Poly-salt plants" adopt the strategy of "fighting poison with poison", excreting the salt absorbed by the roots into the salt bubbles composed of specialized protoplasm, and inhibiting these salts from running from the salt bubbles to other protoplasm of the cells, such as Salina and Suaeda.

Salt-repellent plant - aquatic weed: There is also a salt-repellent plant called Changbing grass, whose root system has the ability to resist salt absorption or reduce salt absorption.

Morphologically. These plants are dwarf.

Dry hard. The leaves are underdeveloped.

Transpiration area is reduced.

Sag stomata. The epidermis has a thick outer skin.

There are often grayish-white villi.

internal structure.

The intercellular space is small.

The fence is well organized.

Some have fleshy leaves.

There are special water storage cells.

It can make the assimilated cells not harmed by high concentrations of salt.

Physiologically. It has a range of salt-resistant properties.

According to the characteristics of adaptation to excess salts.

It can be divided into polysaline plants.

Halogenous plants.

Impermeable plants.

The protoplasm of polysaline plants is particularly tolerant of salt.

They have a particularly high concentration of cells.

It can absorb the water of highly concentrated soil solutions.

For example. Salt horngrass.

Halogenic plants are able to absorb excess salt.

through the stems. Leaf.

Salt glands that are densely packed on the surface are discharged.

Then it was washed away by the wind and rain.

Such as mangrove plants.

Salt-impervious plant cells are very impermeable to salts.

They absorb little or no salt from the soil.

It also improves the plant's ability to absorb water from the soil.
