摘要
以京亚、夏黑、户太8号葡萄为材料，研究熟芽强、藻核酸、青叶素3种新型叶面肥在葡萄上的施用效果。结果表明，3个葡萄品种对3种新型叶面肥的反应程度有很大差别。在春季葡萄萌芽5～6叶期，施用熟芽强30d后，夏黑和户太8号花穗长度分别增长8．92％、11．36％；夏黑和户太8号第4节间分别缩短21．54％、2．63％，第5节问缩短12．36％、2．72％；施用藻核酸30d后，京亚、夏黑、户太8号的花穗分别拉长11．78％、12．58％、4．42％；施用青叶素30d后，3品种葡萄的叶绿素含量分别增加1．67％、10．08％、8．63％，叶面积分别增）31122．54％、4．37％、40．25％。综合看，葡萄萌芽期喷施熟芽强对促进户太8号花穗拉长、夏黑节间缩短有显著的效果；喷施藻核酸对促进葡萄花穗拉长有显著效果；喷施青叶素对提高夏黑叶绿素含量、增大户太8号叶面积有显著效果。
Three new foliar-fertilizers like Shuyaqiang, Zaohesuan, Qingyesu were applied on three varieties（Jingya,Summer Black, Hutai 8）, to investigate the growth and fruiting. The results showed that three varieties had the different sensitivity with the new foliar-fertilizer. After application of Shuyaqiang 30 days later, the panicle length of Summer Black and Hutai 8 increased by 8.92%, 11.36% respectively; and the fourth internode of that shortened by 21.54%, 2.63% respectively, the fifth internode shortened by 12.36%, 2.72%; Application of Zaohesuan 30 days later, the panicle length of Jingya, Summer Black, Hutai 8 increased by 11.78%, 12.58% and 4.42% respectively; After application of Qingyesu, the content of chlorophyll in three varieties increased by 1.67%, 10.08% and 8.63% respectively, the leaf area increased by 22.54%, 4.37% and 40.25% respectively. On the whole, there was a significant effect on the panicle length of Hutai 8 and internode shortening of Summer Black after application of Shuyaqiang, while the application of Zaohesuan on three veriaties influenced their length of panicle distinct, and also Qingyesu could greatly improve the content of chlorophyll and significantly enlarge the leaf area of Hutai 8.
