摘要
在退化草地植被修复中以无纺布覆盖与非覆盖两模式观察出苗密度与出苗时间为基础,对牧草种子发芽出苗影响因素的温度、土壤墒情、土壤空气0_(2)和C0_(2)进行了分析。结果证明:无纺布覆盖草床具有增温、保温、增湿、保湿效果;对种子发芽、空气环要求标准无影响;在一定程度上保护土壤表土,基本无雨水冲刷种子现象。
Based on the emergence density and emergence time,the influencing temperature,soil moisture,soil air 0_(2) and C0_(2) were analyzed.The results proved that the non-woven straw bed has temperature increase,insulation,moisture increase and moisturizing effect;no impact on the air environment standard for seed germination;protect soil topsoil and basically no rain flushing seed phenomenon.
