tenacious survival in the desert, so has been acclaimed as the "hero tree" desert.Euphrates poplar is the only tree species growing in the desert, and very precious, and have a "living fossil plant" said the ginkgo tree comparable.
This is a magical tree species, its growth and the phoenix and blood are always closely linked, this is a changeable tree species, spring and summer for green, late autumn for yellow, winter for red, this is a strong tree species, "alive a thousand years not dead, after death a thousand years do not fall, after falling a thousand years immortal".
Euphrates poplar is the only suitable tree in central Asia.Its charming charm, stubborn character, the fate of misfortunes inspired too much human poetry and philosophy.Through the ages, Euphrates poplar has become a kind of spirit and is worshiped by people.Euphrates poplar is the hometown of the weak river and the juyan sea. The 390,000 mu Euphrates poplar forest here is one of the only three natural river Euphrates poplar forests in the world today
Euphrates poplar is a deciduous medium natural tree, 10-20 meters high, tree age up to 200 years, trunk straight, leaves strange,
growth in the sapling branches of the leaves long and narrow as willow, tree old branches of the leaves are fruity as poplar, there are many gaps in the edge of the leaves, and a bit like maple leaf, so it has "change leaf poplar" "different leaf poplar" said.P. euphratica can grow on the height of salinization of soil, the reason is that plant cell permeability of populus euphratica is strong, it from the main root and lateral root, trunk, bark to the blade can absorb a lot of salt, and can pass the stem leaf secrete gland excretion of sodium, when too much salt accumulation in the body, it can from the knot of the trunk and split will automatically excrete excess salt, white or pale yellow lump crystal formation, called "populus euphratica tears", commonly known as "populus euphratica base".
Local residents use it to make dough to steam steamed buns, as its main ingredient is baking soda, with a purity of 57% to 71%.In addition to edible, euphrine can also be made into soap, also can be used as raw materials for degumming and degreasing of apocynum.An adult tree can discharge tens of kilograms of salt and alkali every year, Euphrates poplar can be called the "soil improvement hero" of "salt extraction and soil improvement".The whole body of euphorbia poplar is a treasure: its hard wood, water resistance and corrosion resistance, through the millennium and immortal, is the first-class construction and furniture materials, loulan, niya and other desert cities euphorbia poplar building materials preserved intact;
Leaves are rich in protein and salt, and are good winter fodder for livestock.The fiber of poplar wood is long, it is the good raw material of papermaking, dead wood is the best fuel.It is highly adaptable to large temperature changes.The water it grows is mainly by diving or river flooding, so it has roots that extend near shallow water.It also has strong root pressure and leaves containing sodium bicarbonate, which makes it resistant to drought and salt.Euphrates poplar forest is a unique and precious forest resource in desert areas. Its primary function is to prevent wind and solidify sand, create suitable oasis climate and form fertile soil.Poplar forests and twigs are important fodder in desert areas.Although wood is not ideal,
but in the lack of wood desert is still important wood;The SAP from the trunk incision is the raw material for food alkali and soap, and can be used as medicine. The local people are called "euphorbia poplar tears" or "wutong tears" (named after the leaves that resemble wutong leaves). Both leaves and flowers can be used as medicine, so euphorbia poplar is the treasure tree in the desert.Due to inappropriate logging and deforestation for land reclamation or grazing, Euphrates poplar forest resources have been destroyed and desertification aggravated by wind erosion or sand accumulation.The Euphrates poplar forest nature reserve has been established in weili, xinjiang.Euphorbia poplar forest euphorbia Mongol language is called "tao lai", is deciduous tree, wood slender soft, leaves broad qing yao.It is one of the rare tree species in nature.Ejin Euphrates poplar forest is one of the only three natural river Euphrates poplar forests in the world, an important barrier to prevent the spread of badain jaran desert to the north, and a natural treasure house of ecology in western China.
