钠、硅及钠硅互作提高梭梭抗旱性的研究

摘要/Abstract

摘要： 采用盆栽试验，施用不同浓度NaCl、H2SiO3及NaCl＋H2SiO3对培育梭梭（Haloxylon a mmodendron）的生长、生理变化及抗逆性方面进行了研究。结果表明,0.3 g·kg-1 NaCl、0.2 g·kg-1 H2SiO3或0.3 g·kg-1 NaCl+0.1 g·kg-1 H2SiO3互作施用均能显著促进梭梭的生长并提高其抗旱性。单施NaCl时，0.3 g·kg-1 NaCl处理培育的梭梭株高、冠幅和鲜重与对照相比分别增加了42%、91%和62%，其主茎直径、主根直径和主根长分别增加了40%、39%和23%。单施H2SiO3时，0.2 g·kg-1 H2SiO3处理培育的梭梭株高、冠幅、鲜重与对照相比分别增加了36%、45%和27%，其主茎直径、主根直径和主根长分别增加了23%、23%和20%。与施用0.3 g·kg-1 NaCl处理相比，0.3 g·kg-1 NaCl+0.1 g·kg-1 H2SiO3互作处理梭梭株高、冠幅、鲜重和主根长分别增加了9%、10%、17%和12%；与施用0.1 g·kg-1 H2SiO3处理相比，0.3 g·kg-1 NaCl+0.1 g·kg-1 H2SiO3互作处理梭梭株高、冠幅和鲜重分别增加了28%、76%和68%，其主茎直径、主根直径和主根长分别增加了30%、32%和27%。这表明适量水平的NaCl+H2SiO3互作施用要比单独施用NaCl或H2SiO3能更有效地促进梭梭的生长并提高其抗旱性。

Abstract: We studied pot cultivated Haloxylon ammodendron’s growth, physiological changes and drought resistance under NaCl, H2SiO3 and NaCl+H2SiO3 treatments. Results show that 0.3 g·kg-1 NaCl, 0.2 g·kg-1 H2SiO3 or 0.3 g·kg-1 NaCl+0.1 g·kg-1 H2SiO3 treatments can effectively promote the growth and improve the drought resistance ofHaloxylon ammodendron. Compared with that under no NaCl treatment, Haloxylon ammodendrons height, crown diameter and fresh weight increased by 42%, 91% and 62% respectively under 0.3 g·kg-1 NaCl treatment, and its main stem diameter, main root diameter and main root length increased by 40%, 39% and 23%, respectively. Compared with that under no H2SiO3 treatment, Haloxylon ammodendrons height, crown diameter and fresh weight increased by 36%, 45% and 27% respectively under 0.2 g·kg-1 H2SiO3 treatment, and its main stem diameter, main root diameter and main root length increased by 23%, 23% and 20%, respectively. Compared with that under 0.3 g·kg-1 NaCl treatment, Haloxylon ammodendrons height, crown diameter, fresh weight and main root length increased by 9%, 10%, 17% and 12% respectively under 0.3 g·kg-1 NaCl+0.1 g·kg-1 H2SiO3 treatment. Compared with that under 0.1 g·kg-1 H2SiO3 treatment, Haloxylon ammodendrons height, crown diameter and fresh weight increased by 28%, 76% and 68% respectively under 0.3 g·kg-1 NaCl+0.1 g·kg-1 H2SiO3 treatment, and its main stem diameter, main root diameter and main root length increased by 30%, 32% and 27%, respectively. It suggests that moderate level of NaCl+H2SiO3 interaction can more effectively promote growth ofHaloxylon ammodendron and improve drought resistance ofHaloxylon ammodendron than separate application of NaCl or H2SiO3.

Key words: Haloxylon ammodendron, NaCl, H2SiO3, mutual application of NaCl and H2SiO3, drought resistance
