- 摘要:
- 为提高大豆的抗逆性、防控病虫害，并提高产量和品质，依据中华人民共和国农业行业标准草案《大豆全生育期叶面“一喷多促”生产技术规程》，以东生22为供试材料，于2024年在黑龙江省齐齐哈尔市克东县开展大豆全生育期“一喷多促”试验，设置常规施肥（CK）、5个“一喷多促”药剂组合处理，分析该技术对大豆生育期生长性状及产量要素指标的影响，同时验证该规程的有效性。结果表明，大豆全生育期叶面“一喷多促”技术前期对大豆生育进程无明显影响，后期可以加快大豆的生育进程，促进早熟1~3 d，该技术可以有效促进大豆生长发育，减少病虫害发生，提升大豆产量。其中处理5效果最好，即每667 m2地块营养生长期第一次喷施0.01%芸苔素内酯8 mL+氨基酸水溶肥60 mL，始花期第二次喷施磷酸二氢钾100 g+硼钼合剂5 mL+17%唑醚·氟环唑60 mL+20%氰戊菊酯乳油30 g，始荚期第三次喷施磷酸二氢钾50 g+17%唑醚·氟环唑60 mL，鼓粒期第四次喷施磷酸二氢钾40 g+20%氰戊菊酯乳油30 g，大豆增产率达12.97%。
- 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 regulation’s 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%.
