不同浓度单氰胺处理对夏黑葡萄生长发育·产量·经济性状的影响

目的]研究不同浓度单氰胺对夏黑葡萄(Vitis vinifera)生长发育、产量和经济性状的影响,为葡萄生产上降低单氰胺使用浓度提供科学依据。方法]用20～50倍50%、52%单氰胺药剂喷施夏黑葡萄,以清水为对照,分析夏黑葡萄的萌芽、成枝、果枝比率、产量、物候期以及果实经济性状等。结果]20～50倍50%、52%单氰胺处理能促使夏黑葡萄提早萌芽,且萌芽整齐,但对开花期、成熟期以及产量、果实经济性状等无明显影响。结论]生产中可以用40～50倍的50%单氰胺进行处理打破夏黑葡萄休眠。

Effects of Hydrogen Cynamide with Different Concentration on Growth and Development,Yield and Economic Characteristics of Summer Black Grape(Vitis vinifera)

Objective] The aim was to study the effects of different concentration hydrogen cynamide on growth and development,yield and economic characteristics of summer black grape,and provide a scientific basis for decreasing its application concentration in grape production.Method] Percentage of bud burst,bearing shoots,cluster number per bearing shoot,yield,main phenophase,fruit economic characteristics of summer black grape prayed with 20-50 times 50% or 52% hydrogen cyanamide were studied.Result] The date of bud burst treated by 20-50 times hydrogen cyanamide advanced and the buds were neat,but there were no significant effects on the date of full flowering,the date of berry ripening,yield,fruit economic traits.Conclusion] 40-50 times 50% hydrogen cyanamide can be used to break summer black grape’s dormancy in its production.
