【摘要】 目的研究头花蓼种子育苗技术。方法头花蓼种子育苗选用肥沃疏松的沙质壤土或疏松肥沃的人工混合土做育苗基质,采用种子拌细土(1∶200)撒播,播种后厢面盖地膜再起塑料拱棚进行保温、保湿,并加强揭膜、浇水等田间管理。结果通过对育苗基质、覆土厚度、播种方法、播种后保温保湿措施等影响头花蓼种子育苗的因素进行系列试验研究,提出了头花蓼种子育苗的可行方法,并研究制订了种苗质量标准。结论头花蓼种子育苗技术可在头花蓼GAP基地建设中推广应用。更多还原

【Abstract】 Objective To study on raising seedling technology of the Polygonum capitatum.Methods Raising seedling the Polygonum capitatum in the fertile and porous sandy loam or artificial mixture raising medium,mixing fine soil and seeds together(1:200),then scattering.After scattering,covering the surface with mulching film,then arching plastic film,heat and wet preservation,and paying attention to field management such as lifting film off and hosing.Results To study on the various raising medium,the thickness of covering soil,the sowing method,the heat and wet preservation measures and other influence on the raising of the Polygonum capitatum.,raised a precarious method to the raising of Polygonum capitatum and worked up seedling quality standards.Conclusion It has been widely applied that raising seedling technology of Polygonum capitatum in construction of GAP base.更多还原
