摘　　要：2019—2020年在张掖市民乐县新天镇王什村,通过灌浆期喷施和播种期拌种新型植物免疫激活蛋白维大力(VDAL),研究其小麦相关性状及产量的影响。结果表明,灌浆期喷施7.5、15.0、22.5 g/hm^(2)处理的小麦千粒重、穗粒重均较清水对照提高;折合产量2019年分别为9523.0、10040.0、10240.0 kg/hm^(2),分别较清水对照增产7.04%、12.85%、15.09%。2020年分别为9433.0、9653.0、9745.0 kg/hm^(2),分别较清水对照增产3.47%、5.89%、6.89%。2020年进行种子拌种,维大力用量86.58、173.16、259.74 g/100 kg种子处理较不拌种对照千粒重增加4.52%~7.23%;穗粒重增加3.30%~6.04%,折合产量分别为9818.0、10138.0、10137.0 kg/hm^(2),较不拌种对照分别增产7.70%、11.21%、11.19%。综合产量表现及效益,初步认为维大力在灌浆期15 g/hm^(2)喷雾处理或播种期173.16 g/100 kg种子拌种处理,均具有较好的节本增效作用,可在今后生产上应用。The application effect of VDAL to spray at grain filling stage and seed dressing at sowing stage on wheat related traits and yield were studied at Wangshi Village,Xintian Town,Minle County,Gansu Province during 2019—2020.The results showed that the 1000-grain weight and average grain weight per spike of wheat treated with sprayed VDAL 7.5 g/hm^(2),15.0 g/hm^(2) and 22.5 g/hm^(2) were increased compared with that control treatment no seed mixing(CK)at filling time.The yield were 9523.0 kg/hm^(2),10040.0 kg/hm^(2),10240.0 kg/hm^(2) in 2019,and 9433.0 kg/hm^(2),9653.0 kg/hm^(2),9745.0 kg/hm^(2) in 2020,increased 7.04%,12.85%,15.10%and 3.47%,5.89%,6.89%,respectively.In 2020,the 1000-grain weight and spike grain weight of Seed coating with 86.58 g/100 kg,173.16 g/100 kg and 259.74 g/100 kg seed mixing treatments increased 4.52%~7.23%and 3.30%-6.04%than CK,the yield were 9818.0 kg/hm^(2),10138.0 kg/hm^(2) and 10137.0 kg/hm^(2) respectively,which increased 7.70%,11.21%and 11.19%than CK.Therefore,sprayed 15 g/hm^(2) with VDAL in filling stage or sowed 173.16 g/100 kg,which had better effect than other conduct,it can be used further in the future.
