摘要: 以自然光为对照(CK),采用不同颜色聚乙烯薄膜覆盖的棚架人工种植药用蔬菜紫苏(Perilla frutescens L. Britt),分析不同颜色棚膜下叶片光谱特性,并对紫苏的生长动态及矿物质的吸收与积累进行研究。结果表明:(1)有色膜覆盖下,400-700nm可见光的光谱占比均较自然光下显著提高(P<0.05),其中蓝膜、紫膜的提高幅度最大,而350-400nm紫外光以及700-900nm红外光波段的光谱占比均较自然光下有所降低;(2)除绿色膜之外,其它有色膜均显著提高单株紫苏的叶片总鲜重(P<0.05),以黄色膜下叶片鲜重最高,红色膜次之;(3)K、P、S、Cu元素在紫苏叶片中的含量以绿色膜下最高,Ca、Mg、Mn元素含量以蓝色膜下最高,各有色膜处理较自然光下均提高了K、Na、S元素在紫苏叶片中的含量而降低了Fe元素含量;(4)K、Cu元素在紫苏叶片中的累积量以红色膜处理最高,P、Ca、Mg累积量以黄色膜处理最高,各有色膜处理较自然光下均提高了K、P、Ca、Na、S、Zn、Cu等7种元素在紫苏叶片中的累积量而降低了Fe元素累积量;(5)自然光下紫苏叶片中的常量无机元素含量比值约为K:Ca:Mg:P:S:Na=107:93:27:15:7:1,微量无机元素含量比值约为Fe:Mn:Zn:Cu=524:21:7:1。综上,有色膜覆盖可以作为一种定向优化露地栽培紫苏生长或矿质品质的设施工程手段。

Abstract: Using scaffolds covered by different colored films, the spectrum characteristics under different colored films were analyzed, and effects of different spectral components on the absorption and content of mineral substances in Perilla leaves were studied, the natural light was taken as the control. The results showed that: (1) percentage of 400-700nm visible light was significantly promoted by all colored films compared with the control, especially by the blue/purple film. On the contrary, the percentage of 350-400nm ultraviolet light and 700-900nm far-red light were reduced with all colored films compared with the control; (2) In addition to the green film, the other colored films significantly increased the total fresh weight of the leaves, with the highest fresh weight under the yellow film; (3) K, P, S, Cu content in Perilla leaves were the highest under green film, while Ca, Mg, Mn were the highest under blue film (BF), and all the films enhanced K, Na, S content while reduced Fe content; (4) The accumulation amounts of K, Cu in Perilla leaves were the highest under red film, while P, Ca, Mg were the highest under yellow film, all films enhanced the accumulation amounts of K, P, Ca, Na, S, Zn, Cu while decreased that of Fe compared with the control; (5) In the natural light, the macroelement content ratio in Perilla leaves was K:Ca:Mg:P:S:Na=107: 93:27:15:7:1, and the microelement content ratio was Fe:Mn:Zn:Cu=524:21:7:1. In summary, the colored film can be applied as an engineering facility method for optimizing the growth and mineral quality of Perilla frutescens.
