Secondly , this paper studied the effect of different concentration nacl on wheatgrass and pointed out that the wheatgrass could maintain well - balanced physiology at light salt stress , but at high salt stress , the membrane penetrability increased , fresh weight reduced , the development was restrained distinctly , and the osmoregulatory substance increased notably , at last the plants perished . from these results , this paper concluded that the wheatgrass had strong salt resistance 二、用不同濃度的nacl (氯化鈉)溶液對冰草植株進行根際滲透脅迫發現，冰草在低鹽濃度脅迫下能夠保持正常的生理代謝，而高濃度鹽脅迫下植株質膜透性增大，鮮重減少，生長明顯受到抑制，有機滲透調節物質顯著增加，長時間脅迫植株死亡。
( 1 ) wheatgrass could remove the active oxygen by heightening the activity of the enzymes and protect the plants from damage at light stress . ( 2 ) wheatgrass could keep turgor pressure by osmoregulation and flexibility of cells to maintain plants developing in drought stress , some osmregulatory substance , such as the proline and the soluble sugar , increased 2 、冰草植株在滲透脅迫條件下會增加滲透調節物質如脯氨酸、可溶性糖類以降低細胞滲透勢，使其在高滲溶液中仍能夠保持一定水分的吸收，植株能夠維持生命活動。
This paper selected two different species of wheatgrasses to research in order to find out the damage and the responses of plants at different stress , some physiological indexes were determined . these results would provide some information to geneticist and breeder who coud make better used of agropyron . the main results were described as follows : firstly , this paper pointed out that effect of peg ( polyethylene glycols ) on some indexes of wheatgrass seedlings 主要通過測定兩種冰草植株在不同濃度脅迫下的一些生理指標，了解不同脅迫對植物造成的傷害以及植物對脅迫的反應，為完善植物抗逆機理提供理論依據，并比較兩種冰草抗逆性，為內蒙古地區抗逆性強的沙生植物的篩選提供理論依據。
Both the complicatedness varieties trees , the thick liquid material that the material differs greatly and the remaining leftover bits after wood processing , wood shaving , sawdust , sub thick liquid , cotton stalk , hemp stalk , bush , crudefiber crop , rice wheatgrass , reed , crudefiber crop , many kinds of goods thick liquid board , wasted paper , bagasse , agrimony etc . canbe fasten separated into the good fibre with higher velocity and proper to rub a block of interval 高濃磨對漿料的適用范圍較廣，無論是樹種復雜，材料差異較大的漿料，還是木材加工后剩余的邊角料，以及蝕花、鋸屑、節子漿、棉稈、麻稈、灌木、枝椏材、稻麥草、芳菲、麻類多種商品漿板、廢紙、甘蔗渣、龍須草等，都能夠以其料高的旋線速成度及適當磨片間隙分離成優質纖維。
Mongolian wheatgrass is a long - lived perennial grass of the genus agropyron . it is well adapted to the cold , arid conditions of the great plains and its leaves are rich in nutrition , so it is wide ranged in arid and semi - arid area of north of china 冰草屬于壽命較長的多年生叢生牧草，抗寒、耐旱性強，營養豐富，是我國北方干旱和半干旱地區改良天然牧草和人工草地的適宜草種。
Prairie grassland accounts for thirty percent of the total area . level and boundless , aneurolepidium , needlegrass and wheatgrass mainly grow there . it has a high quality herbage , making it good pastureland 又稱高平原草原，約占呼倫貝爾草原總面積的30 % ，地勢平坦，一望無垠。主要草種有鹼草、針茅、冰草，牧草質量高，是牛羊最理想的放牧地。
The reasons of strong salt resistance had three aspects : ( 1 ) wheatgrass could reduce the potentiality penetration in cell by increasing the osmoregulatotory substance , so the plants could absorb more water by roots 得出冰草植株耐鹽有三個原因： 1 、冰草植株能夠增加可溶性滲透調節物質，以降低細胞滲透勢，保持植株根系吸水。
( 2 ) wheatgrass could restrain the growth of upground of plants more than that of underground , so the plant could absorb more water and reduced transpiration 2 、冰草植株對地上部分生長的抑制大于對地下部分生長的抑制，這樣可以增強根系吸水，較少葉片的蒸騰失水。
( 3 ) wheatgrass could control na + transport to upground by withholding na + in root which can keep the balance of ion of upground 3 、冰草植株通過將na ~ +截留在根部，控制na ~ +向地上部分的運輸，以維持植株代謝旺盛部位的離子平衡。
( 3 ) wheatgrass could reduce water dissipation by shutting up stoma and let some leaves wither 3 、冰草植株在干旱條件下關閉氣孔，以減少水分散失，葉片萎蔫，以減少蒸騰面積。
