摘要
退化羊草草场经围栏封育或采取栏内翻地补播和耙地补播羊草等人工措施,对改善和增加土壤微生物生物量及活性强度,提高退化羊草草场的生产力是明显的。并且表明,上述人工措施均能取得退化草场不同程度的复壮和改善。
A contrast analysis of the microbiol biomass of all kinds or soil microorganisms and plant above ground biomass on degenerative grassland dominated by Aneurole pidium chinense in all the test regions indicate that artificial measures such as enclosure,inside fence ploughing and sowing A.chinense, harrowing and sowing A.chinense have improved intensity of soil activity considerably, and increased productivity of degenerative grassland, too.This analysis also indicate that all the above-mentioned artificial measures can bring different degree of restoration and improvement to degenerative grassland.
