摘要/Abstract

摘要：

采用盆栽试验，研究了不同水氮处理下骆驼刺（Alhagi sparsifolia）的形态特征、生物量累积和分配特征，并探讨了适合骆驼刺生长的最佳水氮条件。经过2年的水氮处理发现，水分和氮素处理对骆驼刺的株高、冠幅、基茎、地上和地下生物量累积均有显著影响，对生物量分配还存在着明显的交互作用，但在不同生长年份影响也不同。在第1个生长年份，综合评价结果为干旱低氮（田间持水量30%~35%，施氮51 mg N·kg^-1）处理下生长表现最好，主要表现在株高、基茎、根系生物量和根冠比均有明显增加。在第2个生长年份，则为中水中氮处理（田间持水量60%~65%，施氮102 mg N·kg^-1）下综合生长表现最好，主要表现在地上、地下生物量和根冠比均有显著增加。因此，在骆驼刺幼苗生长早期应推荐干旱低氮处理，随株龄增加则为中水中氮处理更合适。

Abstract:

The potting experiment was conducted to study the changes of morphological characteristics,biomass accumulation and allocation of 1- and 2-year-old Alhagi sparsifolia under different water and nitrogen (N) treatments, and to further find out the suitable combination of water and N for the plant growth. The results showed that plant height, canopy, base diameter, shoot and root biomass were significantly affected by water and N supply. The combination of water and N had a significant influence on the biomass allocation of different organs for both growth stages, but the effects differed with growth age. For 1-year-old A. sparsifolia, the highest comprehensive evaluation value of plant growth was found under drought (30%~35% field water capacity (FC)) and low N (51 mg N·kg^-1) treatment, under which there were significantly higher plant height, base diameter, root biomass and root:shoot ratio compared to the control treatment (drought and no N). For 2-year-old A. sparsifolia, shoot and root biomass and root:shoot ratio were highest under middle water and N treatment (60%~65% FC and 102 mg N·kg^-1) compared to other treatments. Correspondingly, the highest comprehensive evaluation value of plant growth was found under this treatment. This suggests that drought and low N treatment was suitable for A. sparsifolia seedlings in the first year, but middle water and N treatment became more appropriate in the second year.
