摘　　要：为探讨"施地佳"土壤调理剂对滨海盐碱地水稻产量与光合效应的影响,以"盐丰47"为试验材料,采用小区对比试验方法进行了田间试验。结果表明:随着土壤调理剂施入量的增加,各处理土壤盐分含量与p H值随之降低,单位面积水稻收获穗数与颖花量、缓苗期与N-n期叶绿素含量、齐穗期净光合速率与气孔导度随之增大;土壤调理剂施入量3.0 kg/667m^2的E2处理获得最高单产727.6 kg/667 m^2,比E1、CK处理分别增产了2.9%、4.8%。"施地佳"土壤调理剂可促进滨海盐碱地改良与水稻增产。The test using small plot contrast experiment to discuss the effect of soil conditioner of Shidijia on the yield and photosynthesis in saline-alkali land which use Yanfeng-47 as entries,the result indicated that soil salt contents and p H value could lower along with the increase of soil conditioner,harvest spike per unit area,spikelet number,chlorophyll concentration of recover period and N-n period,net photosynthetic rate of full heading stage and the stomatal conductance could raise along with the increase of soil conditioner;Treatment E2 can achieve the highest yield with727.6 kg/667 m^2 by using soil conditioner with 3.0 kg/667 m^2,it increased the yield by 2.9% and 4.8% than treatment E1 and CK.Soil conditioner of Shidijia could promote the improvement of saline soil and yield increase.
