其永久萎蔫系数均低于3%。表明这二种枣树的抗旱能力较强。
Permanent wilting coefficient of two jujube varieties both lower than 3 % , jujube has higher drought capacity .

田间试验测得的沙土和粘土的绵毛优若藜的萎蔫系数分别为1.25%和2.96%。
The wither indexes of sandy soil and clay are 1.25 % and 2.96 % by field experimentation .
-
而土壤的田间持水量和有效水含量与土壤有机质、结构系数、团聚度呈极显著的线性正相关,萎蔫系数与质地也呈显著的线性正相关。
In addition , available moisture content was negative correlated with soil texture , wilt coefficient was positive correlated with soil texture .
-
在灌丛沙包上,其土壤水分大多在1.5%左右,远低于植物的萎蔫系数,故不能够满足植物生命活动之需;
On areas of shrub sand dunes , soil water content is only 1.5 % , a level insufficient for plant growth .
-
干湿交替的结果使温室土壤田间持水量减小,萎蔫系数增大,有效水含量也明显减少。
The results of wetting and drying cycle made field water capacity decrease , wilting coefficient increase , and available water capacity decrease in greenhouse soils . 7 .
