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 im... More
