不同颜色薄膜对设施环境及甜椒生长发育和产量品质的影响

Effects of Different Color Films on Facility Environment and Growth,Development,Yield and Quality of Sweet Pepper

以无色透明膜为对照(CK),在相近光照强度下,研究了紫色膜、蓝色膜和红色膜覆盖对设施环境及甜椒生长发育和产量品质的影响。结果表明:不同颜色薄膜覆盖对设施内环境因子的影响不大;红色膜覆盖甜椒茎粗最大,株高较小,而蓝色膜覆盖甜椒茎粗最小,株高较大;蓝色膜覆盖延迟了甜椒开花时间,红色膜覆盖则使甜椒开花期提前;甜椒单株产量和单株果数均以蓝色膜覆盖最低,红色膜覆盖最高,单果重以紫色膜处理最高;蓝色膜覆盖提高了甜椒果实VC和可溶性蛋白含量,果实可溶性糖和游离氨基酸含量则以红色膜处理最高。

Taking ordinary colorless film as control （CK）, the effects of purple film, blue film and red film on facility environment and growth, development, yield and quality of sweet pepper were studied under similar light intensity. The results showed that covering with different color films had little effect on environ- mental factors in facilities. The sweet pepper covered with red film had the largest stem diameter and smaller plant height while that with blue film had the smallest stem diameter and larger plant height. The flowering time of sweet pepper was delayed by blue film and advanced by red film. The yield and fruit number per plant of sweet pepper were the lowest under blue film treatment and the highest under red film treatment. The single fruit weight under purple film treatment was the highest. The VC and soluble protein contents were improved by blue film, and the soluble sugar and free amino acid contents were the highest under red film treatment.
