4种植物生长旺盛期根系易受损的外力类型研究

Shuitu Baochi Xuebao, 2016
在植物生长旺盛期，采用材料试验机测定3～4 a生柠条、沙柳、沙棘、白沙蒿在1～4 mm径级范围内的侧根分支处、相邻上级直根的抗拉力与抗折力，研究4种植物根系易受损的外力类型。结果表明：同径级条件下，柠条和沙柳的侧根分支处、相邻直根均表现为抗拉力小于抗折力，而沙棘和白沙蒿侧根分支处和相邻直根均表现为抗拉力大于抗折力。侧根分支处抗拉强度和抗折强度分别为：柠条(23.70±3.97)＜（33.66±7.74) MPa，沙柳(14.86±1.28)＜（17.31±1.91) MPa，沙棘(10.61±2.40)＞
