为了明确大棚辣椒反季节栽培时畦沟深浅对辣椒生长和产量的影响，在大棚内以畦沟深5 cm、20 cm、35 cm不同处理进行整地做畦，研究了不同畦沟深度对辣椒反季节栽培时土壤温度、水分及辣椒生长、光合参数和产量的影响.结果表明，畦沟深35 cm的处理同畦沟深20 cm、5 cm的处理相比，土壤温度最高，土壤含水量最小；畦沟深35 cm处理的辣椒株高显著高于其他两个处理；各处理辣椒植株的净光合速率( Pn )、气孔导度( Gs )、蒸腾速率( Tr )、胞间CO2浓度( Ci )和叶绿素含量等光合指标均以畦沟深35 cm处理的最高，畦沟深5 cm处理的最低，其中气孔导度(Gs)和蒸腾速率(Tr)等指标3个处理间存在显著差异，净光合速率(Pn)、胞间CO2浓度(Ci)和叶绿素含量等指标，畦沟深35 cm处理与畦沟深5 cm处理相比，存在显著差异；畦沟深35 cm的处理产量比畦沟深20 cm、5 cm的处理分别增加4.32%和19.57%.说明大棚辣椒反季节栽培时采用深沟高畦进行整地做畦，可以提高土温，降低土壤湿度，促进植株生长，提高植物的光合作用，增加产量.

The impacts of furrow depths of 5 cm, 20 cm, 35 cm on soi1 temperature, soi1 moisture, and pepper growth and yie1d parameters ( e. g. photosynthesis and yie1d) were studied. Compared with the furrow depths of 5 and 20 cm, depth of 35 cm showed the highest soi1 temperature and the 1owest soi1 water content. Pepper p1ant in 35-cm furrow depth treatment grew ta11er than those in other two treatments. Peppers in 35-cm furrow depth treatment outperformed other two treatments in photosynthesis efficiency ( Pn ) , stomata conductance ( Gs ) , transpiration rate ( Tr ) , interce11u1ar CO2 concentration ( Ci ) , and ch1orophy11 content, among which, Gs and Tr were significant1y higher, and Pn , Ci and ch1oro-phy11 content were significant1y higher in the 35-cm furrow depth treatment than in 5-cm depth treatment. The pepper in of 35-cm furrow depth treatment out yie1ded other two treatment by increased 4. 32% and 19. 57%, respective1y. This study i11ustrate the necessity of deepening furrow for anti-seasona1 pepper growth and yie1d in greenhouse.
