摘要 以3个甜椒品种为试材,用遮阳网人工模拟弱光环境,研究了弱光对不同甜椒品种生长发育的影响。结果表明:85 %遮
阳处理后3个甜椒品种的现蕾期、开花期、门椒坐果期、二层椒坐果期、始收期、拉秧期都较不遮阳对照明显延后;单株叶片
鲜质量减少43.97 %~77.26 %,单株叶片数减少12.95 %~63.74 %,并且遮光时间越长减少量越大。在本试验的3个品种中,
J04耐弱光性最强,在遮阳条件下其株高、茎粗、单株叶片数和单株叶片鲜质量等生长发育指标均保持较高值,而且单株坐果
数也最多。

Abstract :Taking three different sweet pepper varieties as test materials,and sun shade net to stimulate
artificial low light environment,this paper studied the effect of low light on the growth of different sweet
pepper varieties.The results showed that after 85 % low light treatment,the bud stage,flowering period,the
door pepper fruit setting period,two-layer pepper fruit setting period,harvesting period and defeat seedling
stage of the three varieties were obviously delayed,compared with the control.The fresh weight of single
plant leaves decreased 43.97 %-77.26 % and the number of leaves per plant reduced 12.95 %-63.74 %.The longer
the low light treatment last,the greater the amount of reduced.Among these 3 tested varieties,J04 has the
stronger resistence to low light.Under low light conditions,its plant height,stalk thickness,number of single
plant leaves and fresh weight of single plant leaves were kept in a high value,and its number of fruit
setting was also the highest.
