营养液离子强度对烟草苗期矿质营养吸收与积累的影响
Effect of ionic strength in nutrient solution on mineral nutrients absorption and accumulation of tobacco seedling
摘要
Abstract
Effect of nutrient solution with ionic strength of 0.0079, 0.0159, 0.0318, 0.0635, and 0.127 mol/L on mineral nutrients absorption and accumulation of tobacco were studied. Results showed that as ionic strength changed from 0.0079 mol/L to 0.127 mol/L, tobacco biomass varied in a shape of parabola and peaked at 0.0318 mol/L of ionic strength. Content of N, P in tobacco increased with the increase of ionic strength. Content of K, Zn, and Ca changed in parabola as ionic strength increased and peaked at 0.0318 mol/L. When ionic strength was higher or lower than 0.0318 mol/L, content of K, Zn, and Ca decreased. Change of Mg and Cu content to ionic strength was similar as that of K, Zn, Ca, with peak value of 0.635 mol/L and 0.0159 mol/L, respectively. Content of Mn decreased as ionic strength increased. The accumulations of N, P, Mg, K, Ca, Cu Mn, and Zn all varied in a shape of parabola and peaked at 0.0318 mol/L.关键词
