摘要
盐生植物是指在3.3bar渗透压盐水的生境中生长并完成其生活史的天然植物类群。在青海省有5%的植物为盐生植物,共106种,分属于24科、59属,占我国盐生植物总数的26%,具有丰富的盐生植物多样性。这些盐生植物不仅为农业生产提供了丰富的抗盐种质资源,而且为培育抗盐、耐盐的转基因作物品种提供基因库。另外,在这些盐生植物中含有丰富的药用、食用、工艺以及绿化和固沙植物资源。在不能耕种的盐渍土上直接引种具有经济价值的盐生植物,将会获得较大的经济效益,并且能够充分利用青海省大面积的土地资源,因此开发和利用盐生植物资源具有重要的意义。
Halophyte is the plant which can grow and finish the life history in the 3.3bar osmosis pressure environment, there are 106 categories halophyte, they are 24 families and 59 genera, they account for 5 percent of total flora of Qing-hai province, and account for 26 percent of total halophyte of China, there are abundant halophyte diversity in arid. Halophyte not only provides ample germ plasm resource for agriculture production, but also provides a gene storeroom for cultivating the salt resistant crop varieties. Besides, there are so many plant resources in all these halophytes including officinal, edible, technical, afforest and sand - fix resources. Planting the halophytes in the field which is too much salt to be planted with crop, it can obtain the economy benefit and take so many salinisation land resources of Qing-hai province into use, so it is important to study the halophyte resources.
