Abstract

Abstract: Haloxylon ammodendrom is an excellent tree species in northwest China for windproof/prevention， sand fixation， and ecological balance protection. However， the dry climate and high summer temperatures in the arid desert areas of northwest China severely affect the growth and development of H. ammodendrom seedlings. To explore the suitable planting methods for the growth of the seedlings， this study used 1-year-old H. ammodendron seedlings as experimental subjects and set up 5 different doses of super absorbent polymers （0 g， 1， 2， 3， 4 g） and 4 planting depths （20， 40， 60， 80 cm） for combination treatments. The changes in stomatal morphology and anatomical structure of H.ammodendron after different planting treatments were studied. The results showed that with the increase of water retaining agent dosage and planting depth， the stomatal length， stomatal width， stomatal area， and thickness of various anatomical structures of the seedlings showed a trend of first increasing and then decreasing. The pore density shows a trend of first decreasing and then increasing. Stomatal length， stomatal width， stomatal area， diameter of assimilating branch， stratum corneum， palisade tissue， water storage tissue， vascular column thickness， and duct aperture were all the largest， while stomatal density was the smallest when treated with 3g super absorbent polymer and 60cm planting depth. The application of suitable planting treatments can create a better growth environment for H. ammodendron. When facing environmental stress， it can improve plant stress resistance and effectively alleviate the impact of stress on plants.

Key words: Super absorbent polymer, Planting depth, Haloxylon ammodendronon, Stomatal characteristics, Anatomical structure

摘要： 梭梭（Haloxylon ammodendrom）是中国西北防风固沙，保护生态平衡的优良树种，但西北干旱荒漠区气候干燥、夏季高温严重影响了梭梭幼苗生长发育。为探究适宜梭梭幼苗生长的栽植方式，本研究以1年生梭梭幼苗为实验对象，设置5种不同剂量保水剂（0，1，2，3，4 g），4种栽植深度（20，40，60，80 cm）组合处理，研究不同栽植处理后梭梭的气孔形态和解剖结构的变化。结果表明：随着保水剂剂量和栽植深度的增加，梭梭幼苗气孔长度、气孔宽度、气孔面积、各解剖结构厚度均呈先上升后下降的趋势；气孔密度呈先下降后上升的趋势。其中，3g保水剂、60cm栽植深度处理，气孔长度、气孔宽度、气孔面积、同化枝直径、角质层、栅栏组织、贮水组织、维管柱厚度、导管孔径均最大，气孔密度均最小。说明施用适宜的栽植处理，能够为梭梭创造较好的生长环境，遭遇环境胁迫时，能提高植物抗逆性，有效缓解了胁迫对植物的影响。
