大豆全生育期"一喷多促"技术应用试验
Application Experiment of"Multi-Promotion Spraying"Technology in Whole Growth Period of Soybean
摘要
Abstract
In order to enhance the stress resistance of soybeans,control pests and diseases,and improve yield and quality,following the draft of the Agricultural Industry Standard of the People's Republic of China"Technical Regulations for Foliar'Multi-Promotion Spraying'Production Technology Throughout Soybean Growth Period",this study conducted a soybean'Multi-Promotion Spraying'experiment throughout the entire growth cycle using Dongsheng 22 as test material in Kedong County,Qiqihar City,Heilongjiang Province in 2024.Five treatment groups were established including conventional fertilization(CK)and combined multi-promotion spray treatments.The study analyzed the technology's effects on soybean growth traits and yield components during different growth stages while verifying the regulations effectiveness.Results indicated that the foliar'Multi-Promotion Spraying'technology showed no significant impact on soybean growth progression in early stages but accelerated growth in later stages,promoting 1-3 days earlier maturation.This technology effectively promoted soybean growth,reduced pest and disease incidence,and increased yield.Treatment 5 demonstrated optimal effects:first spray during vegetative growth stage(0.01％brassinolide 8 mL+amino acid water-soluble fertilizer 60 mL),second spray at initial flowering stage(potassium dihydrogen phosphate 100 g+boron-molybdenum complex 5 mL+17％azoxystrobin·fluoxastrobin 60 mL+20％fenvalerate EC 30 g),third spray at pod initiation stage(potassium dihydrogen phosphate 50 g+17％azoxystrobin·fluoxastrobin 60 mL),and fourth spray at grain filling stage(potassium dihydrogen phosphate 40 g+20％fenvalerate EC 30 g)per 667 m2,achieving a yield increase rate of 12.97％.关键词
