红蜘蛛是柑桔树的重要害虫,为深入了解遭红蜘蛛危害的柑桔叶片叶绿素损失情况以及由此导致削减叶片有机物质合成能力,予以生产上提供理论依据,我们开展本试验研究,旨在更深层次提醒人们在生产上重视柑桔红蜘蛛防治。试验结果表明:深绿色叶片的叶绿素含量最高,是黄白色叶片的2.97倍,光合强度是白色叶片的9.39倍,其次是浅绿色叶片类型。红蜘蛛危害造成最严重的是黄白色叶片类型,它的叶绿素损失最多,有机物质合成效率最低。
Red spider is an important pest of citrus tree. In order to further understand the chlorophyll loss of citrus leaves which is endangered by Red Spider, and to provide a theoretical basis for its production, we conducted this experimental research aimed at A deeper reminder of the importance of production in citrus red spider control. The results showed that the content of chlorophyll in dark green leaves was the highest, 2.97 times that of yellowish white leaves, the photosynthetic intensity was 9.39 times that of white leaves, followed by the light green leaves. Red spider damage caused by the most serious type of yellow-white leaves, it has the largest loss of chlorophyll, organic synthesis of the lowest efficiency.
