微肥与生长调节剂对延后栽培‘红地球’葡萄果实发育及品质的影响

以2年生日光温室延后栽培的‘红地球’葡萄植株为试材,通过在葡萄生长期使用3种微肥(包果优1 000倍液、包果良500倍液、苞果(707)500倍液)进行叶面喷施,研究微肥对葡萄坐果率、果实生长和果实品质的影响;在疏穗定果后使用红提大宝和奇宝2种果形剂进行蘸穗处理,研究生长调节剂对果实生长以及果实品质的影响.结果表明:3种微肥均可以显著提高延后栽培‘红地球’葡萄的坐果率、促进果实生长、增大果粒及提高果实品质,其中以包果优1 000倍液应用效果最好;‘红地球’葡萄果粒横径为5mm时,用红提大宝和奇宝进行蘸穗处理,也可以增大果粒、提高果实品质,其中,以红提大宝应用效果最好.

Effect of using microelement fertilizer and fruit shape modifier on fruit development,fruit quality of Red Globe grape under prolonged cultivation cindition

Experiment was conducted with 2-year-old Red Globe grape in Solar-greenhouse prolonged culture,through using three types of microelement fertilizer(Bao guo you 1 000 times,Bao guo liang 500 times,Bao guo(707)500 times)of foliar application in the grape growing season,grapes setting rate of microelement fertilizer,fruit growth and fruit quality were studied.After cluster thinning and fruit fixing using two kinds of fruit shape modifier,Red Globe Da-Bao and Qi-Bao,to dip fruit cluster,grape fruit growth and fruit quality of growth regulators were studied.The results showed that three kinds of microelement fertilizer could be significantly increased prolonged cultivation of Red Globe grape fruit setting rate,to promote fruit growth,enlarge fruits and improve fruit quality,Bao guo you 1 000 times showed the best result.When the diameter of Red Globe grape fruit was 5 mm,using Red Globe Da-Bao and Qi-Bao to dip fruit cluster,could also increase fruit and improve fruit quality,Red Globe Da-Bao showed the best result.
