生态防草布对蒙古黄芪生长的影响

Effects of Biodegradable Weed Control Fabric on the Growth of Astragalus Mongholicus

为了提高药材品质,减少地膜带来的污染,保护生态环境,开展了生态防草布在蒙古黄芪种植中的应用研究。结果表明:采用白地膜、黑地膜、生态防草布覆盖方法种植蒙古黄芪,会对蒙古黄芪生长产生不同的影响。地上部分表现为:采用白地膜会促进蒙古黄芪早期生长,导致出苗早,花期早,种子成熟早,但株高和冠幅低于黑地膜和生态防草布;从产量分析:小区产量最高的是防草布,为110.34kg,较对照提高了24.52%。其次是黑地膜,为108.68kg,再次是白地膜,为93.36kg,对照为88.61kg。由此说明,在蒙古黄芪标准化种植中,生态防草布可以取代传统白地膜、黑地膜,减少地膜对环境造成的污染,研究结果对青海省生态保护和绿色有机农产品输出具有十分重要的意义。

In order to improve the quality of medicinal materials, reduce the pollution caused by plastic film and protect the ecological environment, we studied the application of ecological weeding cloth in the planting of Astragalus mongholicus.The results showed that planting Astragalus mongholicus with white mulching film, black mulching film and ecological weeding cloth had different effects on the growth of Astragalus mongholicus. The aboveground part results showed that the use of white mulching film could promote the early growth of Astragalus mongholicus, resulting in early seedling emergence, early flowering and early seed maturation, but the plant height and crown width were lower than those of black film and ecological weeding cloth.From the yield analysis: the highest yield plot is the ecological weeding cloth, which is 110.34 kg, 24.52% higher than that of the control.Followed by black mulching film, which is 108.68 kg, followed by white mulching film, which is 93.36 kg and the control group is 88.61 kg.Therefore, in the standardized planting of Astragalus mongholicus,the ecological weeding cloth can replace the traditional white mulching film and black mulching film, and reduce the environment pollution caused by the plastic film.The research results are of great significance to the ecological protection and green organic agricultural products export in Qinghai Province.
