摘要： 研究在种子萌发期进行不同覆膜处理对北柴胡幼苗生长情况的影响，筛选适宜覆膜材料，为北柴胡大田栽培提供参考。本试验选用北柴胡幼苗为试验材料，对北柴胡种子在种子萌发期进行草席、黑色地膜、白色地膜、遮阳网4种不同覆膜处理，不覆膜为对照(CK)；种子萌发后撤去遮盖物，并对萌发3个月后的北柴胡幼苗进行相关生理生化指标测定；最后，利用隶属函数分析对柴胡的生理指标进行综合评价。结果表明：不同处理对不同指标影响不同；其中地上、地下干鲜重比值、可溶性糖含量均以草席覆膜为最高；叶绿素含量、可溶性蛋白含量以黑色地膜覆膜处理最高；游离氨基酸含量以对照为最高。综合评价认为，黑色地膜覆膜处理组对北柴胡幼苗生长的影响最为显著。

Abstract: To screen suitable coating materials and provide reference for field cultivation of Bupleurum chinense DC., we studied the effects of different coating treatments on seedling growth during seed germination period. In this experiment, Bupleurum chinense DC. seedling were used as materials, different coating treatments were conducted in seed germination period, which were mats coating, black film coating, white film coating, shading net, and no film was taken as CK; then the covers were removed after seed germination, and the physiological and biochemical indexes were determined after three months of seed germination; finally, the indexes were evaluated by membership function analysis. The results showed that: different treatments had different effects on different indicators, among them, the dry fresh weight ratio of the aboveground and underground and soluble sugar conten were the highest under mats coating treatment; the chlorophyll content and soluble protein content were the highest under black film coating; the free amino acid content was the highest under CK. The comprehensive evaluation showed that the effect of black film coating on the seedling growth of Bupleurum chinense DC. was most significant.
