摘　　要：选用4种不同规格的保温材料,研究覆盖后对小拱棚内辣椒幼苗生长发育的影响。结果表明:不同的保温材料对辣椒幼苗生长发育的影响不同,在茄子幼苗前期,在株高、茎粗、叶片数、叶绿素、地上部鲜重、地下部鲜重、总鲜重等性状上存在显著性差异,但在开展度、地上干重、地下干重上不存在显著性差异;在茄子幼苗中期,在株高、开展度、叶片数、叶绿素、地上部鲜重、地下部鲜重、地上部干重等性状上存在显著差异,但在茎粗、地下部干重上不存在显著性差异;在茄子幼苗后期,在株高、叶绿素、叶片数、地上部鲜重、地下部鲜重、地上部干重、总鲜重上存在显著差异,但在开展度、茎粗、地下部干重、总干重上不存在显著差异。综合来看,40 g/cm2加膜无纺布对辣椒子幼苗生长发育最有利,4种保温材料对幼苗期生长发育表现的有利顺序为:A2>A1>A4>A3。In this study, we chosed four new thermal conservation materials as different treatments to study the effect of them on the growth and development of eggplant seedling. The results were as follows, during the pre-seedling time, pepper seedlings were measured with significant difference on the height, stem diameter, leaves number, chlorophyll ground flesh weight, underground fresh weight and total flesh weight, but not on the plant expansion ground dry weight, the underground dry weight, total flesh weight and dry weight; During the mid-seedling time, it＇s significantly different on the height, plant expansion, leaves number, chlorophyll, ground flesh weight, underground flesh weight, ground dry weight, total fresh weight and total dry weight ,but not on stem diameter and underground dry weight; During the late-seedling time, it ＇s significantly different on the height, leaves number, chlorophyll, ground flesh weight, underground flesh weight, total flesh weight and ground dry weight, but not on the stem diameter, plant expansion, and ground dry weight and total dry weight. Comprehensively considering the new thermal conservation material were beneficial to the growth and development of eggplant seedlings, of which 40 g/cm^2 coated non-woven fabrics was best.
