钠硅互作提高白刺抗旱性的研究
Effect of Na and Si interactions on the drought resistance of Nitrarial tangutorum
摘要
Abstract
The effects on growth and drought resistance of potted Nitrarial tangutorum treated with different concentrations of NaCl and Na2SiO3 were studied. Growth of N. tangutorum was promoted and drought resistance improved by 1. 2 g/kg NaCl alone or a 0. 3 g/kg NaCl+0. 72 g/kg Na2SiO3 combination. Compared with the control, application of NaCl alone increased plant height, root length and dry weight by 47%, 25% and 236%, respectively. Application of the NaCl/Na2SiO3 combination effectively promoted growth and improved drought resistance of N. tangutorum more than the NaCl treatment. Compared with the NaCl treatment, the combination treatment increased plant height, root length and dry weight by 81% , 43% and 193% , respectively. It is suggested that moderate levels of Na and Si combinations could more effectively promote growth and improve drought resistance of N. tangutorum than the application of NaCl alone.关键词
