典型草原地区退化草原的改良及提高生产力途径的研究

作者在内蒙古典型草原地区进行了围栏封育、轻耙松土、耕翻撩荒、播种羊草和羊草混播旱生豆科植物，经过5年的试验，显示出这些措施都能不同程度地提高产草量；由于这些改良措施均在七月雨季进行，翻耕后的植物当年即可覆盖土表，所以也不会导致沙化。

RESEARCH ON IMPROVING DEGENERATIVE STEPPE AND METHODS FOR INCREASING PRODUCTIVITY OF THE STEPPE REGION

The treatments used by the authors are as follows, enclosure, light harrowing ploughing light harrowing after planting and ploughing before planting Aneurolepidium chinense and mixed legume plants on the degenerative steppe in Inner Mongolia. We want to find an effective method in order to improve the degenerative steppe and recover its productivity. After 5 years’experimenting with the above treatments, we found they were effective methods for improving degenerative steppe, especially effective were enclosure, polughing and ploughing before planting A. Chinense.
