摘要
朝鲜碱茅和小花碱茅属禾本科碱茅属植物,混生在吉林省西部地区地势低平易涝的盐渍土和退化的羊草草甸上。具有耐旱、耐盐碱、喜湿和抗寒的特性。营养期粗蛋白质为18.06%,粗脂肪为4.61%,是各种家畜的优良牧草。用其改良吉林省西部地区苏打盐土草原碱斑和表土(0～5cm)含盐量1.0～3.0%的土壤,可亩产干草150～250公斤,生长8年不变,种过3年的土地,含盐量由原来的1.8%下降到0.22～0.24%。区域试验初步表明,碱茅草对甘肃、新疆、内蒙古等不同类型盐碱地都有良好的改良作用。
Puccinellia chinampoensis and Puccinellia tenuiflora are two kinds of grass of Puccinellia Parl. They grow on low-wet-flat saline soil and degenerated Chinese wildrye meadow, they have character of tolerent drought, alkali and salt, like wet and cold resistant. Crude protein and crude fat are 18.06% and 4.61% respectively in growth season. Livestock like eating. They can improved soda-saline soil that salinity of surface soil(0～5cm) is 1.0-3.0% after improved,drymatter can reach 150～250kg/mu,It can keep growing eighth year.The soil salinity reduced from 1.8% to 0.22-0.24% after three years.The result primarily proved that the grass effect is better in improving different saline-alkali soil in Gansu,Xinjiang,Inner Mongolia and so on.
