Phytochemicals(including proteins, lipids, carbohydrates, vitamins, minerals,phenolic compounds and so on) are one of the most important groups of the bioactive compounds in vegetables and fruits, benefit for human health. The phytochemicals biosynthesis is affected by environmental factors, and light in particular. Light effects can be categorized in photoperiod, intensity and quality. While it is widely known that light intensity can positively affect phytochemicals accumulation, the effects of light quality are more complex and often reported with mixed results. So this review focuses on the currently knowledge about different light quality on the control of phytochemicals biosynthesis. A better knowledge on these regulatory mechanisms will be useful for modifying phytochemicals biosynthesis in vegetables and fruits.
以废弃中药渣为原料进行高温堆肥试验,在不同初始p H值及不同覆盖材料下,采用好氧人工翻堆堆肥方式,研究中药渣高温堆制过程中理化性状(温度、电导率、p H、全氮、全磷、全钾)的动态变化及种子发芽率。结果表明:中药渣初始p H 6~7处理的堆肥温度较高,其种子发芽率在堆制25 d时达到81.25%,初始p H 4~5处理的堆肥在堆制结束后其有机质、全氮、全磷、全钾含量最高。覆盖白膜处理的中药渣腐熟效果比黑膜覆盖处理的好。覆盖白膜处理的中药渣堆肥温度较高,在堆制过程中p H上升快,堆制结束后有机质、全氮、全磷、全钾含量较高。
