使用砂培法,每天两次通过灌溉水人为地盐化培养砂,测定了盐浓度对伏令夏橙(Citrus sinensis (L.) Osbeck)产量和果实品质的影响。在10年研究期间,产量随盐浓度的提高而降低。减产并不因为果实变小,而是结果量减少。盐浓度的提高减少了果皮厚度,推迟果实成熟,但并不影响果实品质的其他指标。 The effect of salt concentration on the yield and fruit quality of Citrus sinensis (L.) Osbeck was measured using sand culture method. The sand was artificially salted twice daily by irrigation water. During the 10-year study, yield decreased with increasing salt concentration. The reduction is not due to the fact that the fruit becomes smaller but the amount of the result is reduced. Increasing the salt concentration reduces the pericarp thickness and postpones the fruit maturity, but does not affect other indicators of fruit quality.
