不同修剪强度对油茶春梢和结实性状的影响
The Effect of Different Pruning Intensity on Spring Shoot and Fruit Traits in Camellia oleifera
摘要
Abstract
In order to better promote the application and efficient cultivation of high-quality oil tea varieties,'Changlin 4'and'Changlin 40'with significant differences in tree structure were selected in this study.Through thinning and shortening techniques,the effects of different in-tensities of pruning on canopy photosynthetic utilization,fruit setting rate,spring shoot growth and mineral nutrient content,and fruit traits were analyzed.The results showed that pruning treatment reduced the PAR interception rate of the canopy,and the higher the pruning intensity,the lower the PAR interception rate was found;pruning treatment significantly increased the length of spring shoots,increased the nitrogen and po-tassium content of spring shoot leaves,and reduced the calcium content of leaves.There was no significant difference between different pruning intensities treatments;moderately increasing pruning intensity can improve the fruit setting rate of Camellia oleifera,and pruning treatment af-fects the weight of fresh fruits,the ratio of seed to fresh fruit,and the number of seeds per fruit,but has no significant effect on the fruit shape index.关键词
