摘要
试验以4年生的两个葡萄品种为试验材料,采用叶面喷施方法,研究了几种植物营养素对葡萄生育的影响.结果表明,几种植物营养素对葡萄枝条成熟和提高果实品质等方面效果明显;果粒重比对照增幅0.15％～15.75％,含糖量增幅3.87％～4.82％.植物营养素可显著提高葡萄果实品质和产值,喷施营养素能提高座果率,增加单粒重和产量,提前着色,增加商品价值.
The grape is a kind of nutritional condition sensitive trees.Adequate fertilizer,plant grows hale,can significantly improve the yield and quality.Correct diagnosis of grape nutrition, rational fertilization on grape production yield,quality and economic efficiency are closely related.This experiment with two varieties of four annual grape as test materials,using foliar spraying method,study on several kinds of plant nutrient on grape growth.The results showed that the effect of several plant nutrients on mature grape branches and improve fruit quality aspects; the average grain weight higher than the contrast by 7.18%,and the average sugar content increased by 4.59% .The plant nutrients could significantly improve grape fruit quality and production value,spraying nutrients could improve fruit set,increased single grain weight and yield,early coloring and increase the value of the goods.
