【摘要】 对三四五年黄连进行5个不同荫蔽度处理,分别是全光照,30%,45%,60%,75%,结果表明,三四五年生黄连最适荫蔽度分别为60%,45%和全光照。同一荫蔽度下不同年龄黄连抗性物质有着明显差异。实验可以为实际生产提供一定得理论基础指导。更多还原

【Abstract】 Coptis chinensis Franch of 3,4 and 5-age years were given treatments with 5 levels of shading intensities 0, 30%, 45%, 60%, 75%.The result showed that the most suitable shadings for Coptis chinensis franch of 3,4 and 5-age years are 60%, 45%,0.The same shading influence remarkably the resistant substance of different-age of 3,4 and 5-age years The experiment can provide theory guidance for production.更多还原
