在退化羊草草地上进行松土和施肥试验表明,松土可改善土壤的物理性状,促进牧草的生长发育,产草量可提高35.3％,增产效果可达5年以上。松土同时并施肥,增产效果更明显,亩施7kgN和3kgP_2O_5的草场,产草量比松土草场增加78.9％,并可提高羊草的蛋白质含量。 The experiments of soil de-rating and fertilization on degraded Leymus chinensis grass showed that loosening soil could improve the physical properties of the soil and promote the growth and development of forage grass. The yield of grass can be increased by 35.3% and the yield increase can reach more than 5 years. Loose soil at the same time and fertilization, the yield increase effect is more obvious, mushu 7kgN and 3kgP_2O_5 pasture, grass yield increased by 78.9% than the sod ground, and can improve the protein content of Leymus chinensis.
