摘　　要：本文研究了植物激活蛋白HrpNEcc及其复配制剂对大白菜生长、产量和品质的影响。结果表明,使用150 g/hm^(2)HrpNEcc处理的大白菜,菜心饱满度达到97.32%,较对照增产54.05%;同时显著改善了品质指标,可溶性糖、粗蛋白和维生素C含量分别提升34.64%、46.13%和41.14%,而粗纤维含量降低46.3%。通过对比试验发现,该处理效果显著优于HrpNEcc 45 g/hm^(2)+壳聚糖45 g/hm^(2)复配处理、壳聚糖150 g/hm^(2)处理、0.004%芸苔素内酯3000倍液处理以及对照处理。激活蛋白HrpNEcc能显著促进大白菜的生长发育并有效提升其产量与品质。此外,研究还证实HrpNEcc对防治大白菜软腐病有显著效果,最高防效可达85.85%。本研究成果也为在其他作物上的应用提供了科学依据。This study investigated the effects of the plant activator protein HrpNEcc and its compound preparations on the growth,yield,and quality of Chinese Cabbage(Brassica rapa subsp.pekinensis).The findings indicated that HrpNEcc significantly promoted the growth and enhanced the yield and quality of Chinese Cabbage.Specifically,the application of HrpNEcc at 150 g/hm^(2)resulted in a head fullness of 97.32%,a yield increase of 54.05%compared to the control.Significant quality improvements were observed,including 34.64%,46.13%,and 41.14%increases in soluble sugar,crude protein,and vitamin C contents respectively,along with a 46.3%reduction in crude fiber content.Comparative experiments revealed the superiority of this treatment over alternative approaches:the combined treatment of HrpNEcc(45 g/hm^(2))and chitosan(45 g/hm^(2)),chitosan alone(150 g/hm^(2)),0.004%brassinolide(3000-fold dilution),and the control group.Furthermore,HrpNEcc showed significant efficacy in the prevention and control of Chinese Cabbage soft rot disease,with a maximum control efficacy of 85.85%.The results of the study demonstrate that the plant activator protein HrpNEcc plays an important role in improving the yield and quality of Chinese Cabbage and provides a scientific basis for its application in other crops.
