调光生态膜对蔬菜品质的影响

The Effect of Sunlight Conditioning Agriculture Film on Vegetable Quality

调光生态膜能将太阳辐射中不能被植物光合作用利用的光谱成分通过其中的荧光转光剂转换为光合作用有效光谱,其功效不仅是在低温寡照季节促进植物生长,提高产量,也会对植物中各种营养成分的含量产生影响。本文通过用国标法对光生态膜和对照膜苫盖下的番茄、黄瓜、甜椒中可溶性总糖、维生素C、可滴定酸度、粗蛋白等营养成分的定量测定和对比分析,得出了调光生态膜对这些蔬菜营养成分的改善提高比。

The light conditioning biology film for agriculture can transfer certain unused solar radiation in photosynthesis of vegetables into photosynthetically active radiation through the fluorescence additive in it. its value not only lies in promoting the growth of vegetables and increasing yield hut also in affecting the nutrients in vegetables. By quantity measurement of dissolubility sugar, Vitamin C, titrable acidity, coarse protein in tomatoes, cucumber, pimiento grown under the sunlight conditioning film and the conventional film according to GB/T method series and the following analysis. We get the increased ratio of these nutrients in vegetables under light conditioning film comparing with the conventional film.
