不同整形修剪方式对温室油桃光强分布及产量和品质的影响

以艳光油桃为试材,研究长枝修剪处理与短枝修剪处理对温室油桃树光强分布及产量、品质的影响。结果表明:长枝修剪处理树冠内大于30%相对光照强度所占比例明显大于短枝修剪处理。长枝修剪处理冠层光照分布除最下2层略有不均之外,其余各层分布均匀一致,短枝修剪处理除最上1层分布比较均匀之外,其余各层分布明显不均;长枝修剪处理单株结果数量、产量及果实可溶性固形物均明显大于短枝修剪处理单株结果数量、产量及果实可溶性固形物。

Effects of Different Pruning Methods on the Light Distribution and Yield and Quality of Nectarine in Greenhouse

’Yanguang’ nectarine was used as test material to study the effect of long branch pruning and short brach pruning on the light distribution and yield and quality of nectarine in greenhouse.The results showed that the proportion the crown of greater than 30%relative light intensity of long-branch pruning was significantly greater than short brach pruning.Light distribution of canopy of long-branch pruning except most lower 2 layer slightly not uniform,the uniform distribution of the remaining layers;short brach pruning,except the most above 1 layer was uniform distribution,the rest of the distribution was uneven.The results number of per plant,yield and soluble solids of long-branch pruning were significantly higher than short brach.
