摘  要:
对选育出的4个耐盐小麦新品系987705、9876、986515、985501进行了耐盐发芽、盆栽、小区试验及生态适应性的区域试验,以新冬26号、轮抗6号和德选1号为对照。试验结果表明:盐浓度在1.2%时,各品系发芽率的大小为987705>9876>986515>新冬26号>988501>轮抗6号>德选1号,其中,轮抗6号、德选1号发芽率低于50%。在以氯化物-硫酸盐为主的盆栽试验及小区比较试验中,土壤盐分含量为1.0%时,987705产量要高于对照新冬26号和轮抗6号,988501、986515的产量与新冬26号相近而高于轮抗6号。4个耐盐小麦新品系在轻度~中度盐渍化地上的生态区域适应试验中,常规管理条件下,均正常生长发育,全生育期均未表现出盐害现象,具有植株较矮、穗较长、小穗多、穗粒数多、籽粒大等特点,具有较高的生产效益。

摘  要:
Four new lines of salt-tolerant wheat lines were chosen to study their salt enduring and suitability characteristics by pot and plot tests.The results show that,compared with Xindong No.26,Lunkang No.6 and Dexuan No.1 as the control,the new wheat salt-tolerant lines 987705,9876,986515,985501 have stronger salttolerance and higher yielding capacity in saline soil tests.When soil salinity is 1.2%,the germination rate of different lines is in the order of 987705>9876>986515>Xindong No.26>988501>50%>Lunkang No.6>Dexuan No.1.The new lines of salt-tolerant wheat can normally develop in the soil at salinity <1.0%,showing no salt injury in the whole growth period.Their primary agronomic properties are characterized as short stalks,long spikes,lots of little spikes,more grains per spike, big grains and so on,which result in high benefit of production.
