摘要
以辣椒为试材,在温室低温逆境下,研究了远红外电热膜辐射加温在冬春茬辣椒育苗上的应用效果。结果表明:采用远红外电热膜辐射加温处理,辣椒种子发芽势和发芽率显著提高,叶片光合速率和根系活力增加,植株长势和根系发育显著优于对照,有利于壮苗培育。加温方式比较,远红外电热膜覆土2cm加温效果优于直接加温处理。采用远红外电热膜辐射加温技术可缩短辣椒苗龄15d,经济、生态和社会效益显著。
Taking hot pepper as material,effect of the far-infrared heating film radiation on winter-spring hot pepper seedling was studied in the the greenhouse low temperature stress conditions.The results showed that the treatments of far-infrared heating film radiation promoted germination potential and germination rate significantly.Increased photosynthesis and root activity of the treatments resulted in more plant growth and root system development significantly,which helped to cultivate strong seedling.Compared with direct heating,the effects of heating with 2cm earth covered on the far-infrared heating film radiation were better.As a result,the treatment of far-infrared heating film radiation can reduce 15 days of seedling age in hot pepper and produce remarkable economic,ecological and social benefits.
