摘　　要：选用4种不同规格的保温材料,研究覆盖不同保温材料对小拱棚内茄子幼苗生长发育的影响。试验结果表明,各处理在茄子幼苗前期,在株高、茎粗、叶片数、叶绿素含量、地上部鲜质量、地下部鲜质量6个方面均存在显著性差异;在茄子幼苗中期,处理间在株高、茎粗、开展度、叶绿素含量、地上部鲜质量、地下部鲜质量、地上部干质量、地下部干质量方面存在显著差异;在茄子幼苗后期,处理间在株高、叶片数、地上部干质量、地下部干质量、地下部鲜质量方面存在显著性差异。综合来看,覆盖40g/cm2有膜无纺布+塑料膜对茄子幼苗生长发育最为有利。Four new thermal insulation materials were chosen as different treatments to study the effect of them on the growth and development of eggplant seedling. The results showed that during the early stage, eggplant seedlings were measured. The significant differences were observed in the height, stem diameter, leaf number, chlorophyll content, underground fresh weight, but not in the plant frame, aboveground dry weight, underground dry weight, total fresh weight and dry weight. During the mid-seedling stage, it＇s significantly different in the height, stem diameter, plant frame, chlorophyll content, aboveground fresh weight, underground fresh weight, aboveground dry weight, underground dry weight, but not in leaf number. During the late stage, it varied significantly in the height, stem leaves number, underground dry weight and overground dry weight, but not in the stem diameter, plant frame, chlorophyll content and overground fresh weight. Comprehensively considering the new thermall insulation material were beneficial to the growth and development of eggplant seedlings, of which 40 g/cm^2 coated non-woven fabrics was the best.
