摘  要:
在天山乌鲁木齐段的山地草原和山地荒漠草原,使用传统的补播方法,在同一地区对3种耐旱牧草在不同生境条件下的补播建植情况进行了比较。三年的试验结果表明,在年降水量为200~300mm 的山区干旱退化草地上,新麦草的表现较差,而杂花苜蓿及木地肤的建植效果较好,并与环境因素的互作关系极为密切。

摘  要:
Using traditional overdrilling method in mountain desert grassland of Tianshan and mountain grassland of Tianshan mountain,Urumqi section,and in the same area three drought-tolerant herbage species in different habitats,the condition of overdrilling and establishing were com- pared.A three year's test result showed that the appearance of Psathyrostachs juncea was worse, but the establishing effect of Medicago varia and Kochia prostrata were better,and there was a close intercorrelation with environmental factor in dry desert regressive grassland of 200~300mm precipitation per year.
