| 摘 要： | 以青南地区称多县歇武乡典型的退化高寒草地为对象，采用正交试验方法，通过施肥、补播、除杂等综合技术，对退化天然草地进行综合复壮试验。结果表明：施肥是最主要的复壮措施，当施以尿素105．0kg/hm^2，二铵60．0kg/hm^2，氯化钾22．5kg/hm^2时，经济效益最高。复壮技术组合中，以A3B3C2最好，即除杂100％，施用尿素150kg/hm^2、二铵105kg/hm^2、氯化钾30kg/hm^2、披碱草15kg/hm^2为首选技术组合。

| Abstract: | The comprehensive rejuvenation experiment of degeneration native grassland which was a typical degeneration alpine-cold grassland was conducted by means of orthogonal experimental design and using comprehensive technology including applying fertilizer,re-sowing and weeding.The results showed that applying fertilizer was the most mainly rejuvement measures for degeneration natural grassland.when 105kg/hm~2 urea,60kg/hm~2,(NH_4)_2HPO_4,22.5kg/hm~2KCL were applyed,the economic benefit was optimum.In all experiment groups,A_3B_3C_2 combination was optimum technology combinacion,that was,100% weeding,applying 150kg/hm~2 urea,105kg/hm~ ,(NH_4)_2HPO_4,30kg/hm~2KCL,re-sowing 15kg/hm~2 Elymus dahuricus turce. |
