摘　　要：为筛选优质高产水稻品种,选取7份育种材料,分别种植于新建试验基地常规试验田、低肥试验田、复垦盐碱试验基地进行田间对比试验。试验结果表明:不同试验材料在相同试验条件下产量差异较大,尤其在高盐浓度试验条件下差异明显;同一试验材料在不同试验条件下产量及相关性状也存在表现差异,高盐浓度试验差异明显。常规施肥处理,平均产量为506.2 kg/667 m^2,产量较高的R5、R6、R7比平均产量分别增产16.0%、3.6%、4.3%;低肥试验处理,平均产量为500.4 kg/667 m^2,R1、R2、R3、R5比平均产量分别增产4.4%、1.0%、0.2%、2.0%;土壤盐碱危害较重的复垦基地,平均产量为431.8 kg/667 m^2,R2、R3、R6比平均产量增产17.6%、8.7%、7.7%。其中R5表现出低肥条件长势优良,R6在重盐碱条件下产量较高,因此可作为后期育种筛选目标。For screening high quality and high yield rice varieties,select 7 materials,planting conventional plots,low fertilizer plots,reclamation saline test base for field contrast test.Experimental results show that different test materials in production under same test conditions are different,especially under the condition of high salt concentration test difference obvious;The same test materials in production under different test conditions and the related properties also show differences,test of high salt concentration difference is obvious.Conventional fertilization treatment,an average of 506.2 kg/667 m2,R5,R6 and R7 yield is higher than the average per mu yield increased by 16.0%,3.6%and 4.3%respectively;Low fat test processing,an average of 500.4 kg/667 m2,R1,R2,R3,R5 than average per mu yield increased by 4.4%,1.0%,0.2%and 1.0%,respectively;Soil salinity heavy damage in the base of land reclamation,on average 431.8 kg/667 m2,R2,R3 and R6 than average yield increase 17.6%,8.7%,7.7%.Test of R5 shows good under the condition of low fertilizer condition,R6 in heavy saline conditions,yield is higher,therefore can be used as the late breeding selection target.
