摘要
试验结果表明,采取围栏封育、灭鼠、施肥、除莠、补播等草地改良措施,可明显提高退化天然草地产草量,同时可有效的改善草地质量。随着改良期限的延长,则改良效果越加明显,整个草地向良性的方向转化。
A study on some techiques to increase natural grassland production The study results showed that the natural grassland yield increased obivously when fencing,rodent controlling,fertilizing,and resow were involved in the grassland production,and improved the quality As long as the measures adopting,the effectiveness of improvement is better
