【摘要】 为探讨光照对勋章菊生长的影响,以勋章菊为试验材料,对不同树冠树荫下光照强度和人工模拟树荫光强对勋章菊生长状况的调查,探讨了适合勋章菊正常生长和应用的光照条件。结果表明:光照强度在7000lx以下,勋章菊不能正常生长,且不能开花,植株株型、株高、芽数和花蕾数明显异于对照区,而在覆盖率为1/3和2/3的光照下,勋章菊长势良好,株型优美,花蕾和新芽明显较多。这一结果为勋章菊的树基建植和景观应用提供科学依据。更多还原

【Abstract】 In order to explore the effect of illumination on Gazania rigens growth,we chose Gazania rigens as experment materials, investigated effects of different tree shade illumination intensity between natural illumination and artificial conditions on Gazania rigensin growth,and found out the optimal illumination condition for Gazania rigensin normal growth and application. The result showed that when illumination intensity below 70001ux,Gazania rigensin cant grow normally.They grew abnormally, couldntblossom.Besides,their plant type,height,leafbud number and flower bud number were different from the condition of contrast area distinguishly.When under the condition of 1/3 rate of coverage and 2/3 rate of illumination,Gazania rigensin grew very well,there were obviously more flower bud and new bud than in other conditions.This result provided scientific basis for Gazania rigens tree infrastructure planting and landscape application.更多还原
