草原盐碱地中的有害盐在土壤表层逐渐积累后,析出结晶盐和结晶碱,形成草原碱斑。地处内陆盐碱区的吉林省西部羊草、杂类草草原正遭受草原碱斑的侵蚀,畜牧业生产受到严重危害。吉林省农业科学院选育出的碱茅草,种植在草原上,草原碱斑得到明显的改良。碱茅草,属禾本科,多年生,丛生草,花期平均草高80～90厘米,是贮藏和放牧的优良牧草。根据碱茅草种子发芽生理特点和草原碱斑土的特
The harmful salt in the grassland saline-alkali soil gradually accumulates on the surface of the soil, and the crystalline salt and the crystalline alkali are precipitated to form grassland alkali spots. The grassland of the western part of Jilin Province, which is located in the inland saline-alkali region, is being attacked by alkali spot in grassland and the livestock husbandry is seriously harmed. Jilin Province Academy of Agricultural Sciences bred eskaterina grass, planted in the prairie, grassland alkali stain has been significantly improved. Alkali grass, a grass, perennial, tufted grass, flowering average grass height of 80 to 90 cm, is an excellent grazing and grazing grass. According to the germination characteristics of the alkali thatch grass seeds and grassland alkaline soil special
