摘要
以黄金榕、花斑垂叶榕、乳斑榕的苗木为试验材料,来探讨不同遮荫强度苗木生长、水份利用及苗木生长环境的影响,试验表明:一层遮荫网处理的苗木比无遮荫网和二层遮荫网处理的苗木在株高、冠幅、根径以及叶片数目等方面均增长较快,苗木的地下部分、叶和茎含水量均较低。无遮荫处理利用较多水分,以及土壤温度在14:00点左右的时间明显高于所有的遮荫处理。
The saplings of Ficus microcarpa, Ficus benjamina, Ficus microcarpa are chosen as experimental materials to study influences of diverse intensities of shade on the growth, taking advantage of water and settings. It shows that the saplings under one - layer shade net grow faster in height, crown, root diameter, number of leaves than those under two layer net or without net, while there is less moisture content in underground parts, leaves and stems. It also reveals under the condition of shadeless disposal more water used, and the temperature at about 14：00 is obviously much higher than any other situations.
