采用不同播种时间、不同覆盖物、不同覆土厚度等方法进行丹参播种育苗试验。综合比较出苗率、根数及主根生长情况,结果表明:有覆盖物比无覆盖物好;夏播以麦草覆盖为宜;春播以地膜覆盖为宜;夏播比春播好;覆土厚度以0.5cm为宜。
Based on experiments of salvia seedings-raising by various ways and on the comparison and contrast of the experimenal results,a conclusion is obtainde: when coverede,the seedings grow better; cover with wheat straw in sumrer,while with plastic film in spring;raising seedings in summer is better than in spring;the ideal thickness of earth is helWf a centimetre.
