山葡萄掐花序尖和疏果粒对增产效果的研究

Effects of Removing Inflorescence Tip and Thinning Fruit on Yield Increase of Vitis amurensis Rupr.

以酿酒葡萄新品种"北冰红"及新品系"94-7-75"、"98-8-165"、"2001-6-135"为试材,研究了山葡萄品种(品系)掐花序尖及疏果粒对果实质量和产量的影响。结果表明:"北冰红"、"2001-6-135"、"98-8-165"和"94-7-75"掐除花序尖2/5和疏果粒,比对照平均减产12.0%。掐除花序尖1/5和疏果粒情况下,坐果率、果粒均重、果穗均重和果实含糖量与对照相比,平均提高6.7%、4.6%、7.6%和1.8%,比对照平均增产12.0%;其中:"98-8-165"和"94-7-75"分别比对照增产8.5%和9.0%,"北冰红"、"2001-6-135"增产幅度较大,分别比对照增产15.2%和16.9%,增产效果显著。

Using new varietyies and new lines of wine grape as material,the effects of quality and yield with removal inflorescence tip and thinning fruit of Vitis amurensis Rupr.were studied.The results showed that removal of 2/5 inflorescence tip and thinning fruit of ＇Beibinghong＇,＇2001-6-135＇,＇98-8-165＇ and ＇94-7-75＇,the yield decreaed 12% than control.Removal of 1/5 inflorescence tip,fruit setting rate,ruit weight,cluster weight and sugar content were increased 6.7%,4.6%,7.6% and 1.8% respectively,average yield were increased 12%,of which yield of ＇98-8-165＇ and ＇94-7-75＇ were increased respectively 8.5% and 9.0% than control,＇Beibinghong＇ and ＇2001-6-135＇were increased significantly 15.2% and 16.9%,the effect was evident on the range of yield increase.
