枇杷二次短截修剪对结果母枝和果实品质的影响

摘要

为提高枇杷特级果比例,研究二次短截修剪对早钟6号枇杷结果母枝质量、果实品质和产量效益的影响.结果表明:枇杷结果母枝经过二次短截修剪可诱导侧生枝转为中心枝,且中心枝增粗,节间变短,叶片增多增厚增重,从而提高结果母枝的质量.二次短截修剪的中心枝,与对照中心枝相比,单果重增加19.87 g,提高了34.69％;穗重增加55.72 g,提高了32.05％；果实的总糖含量比对照增加1.23个百分点:特级果比例大幅增加,65.0 g以上特级果率为75.76％,是对照的2.8倍;每公顷产值增加34 739.27元,提高了61.14％.说明枇杷结果母枝二次短截修剪可达到大果、优质、丰产、高效的目的.%In order to improve the extra grade quality fruit proportion of loquat, the influence on fruiting cane, fruit quality and production benefit of loquat by twice cutting back pruning were studied. The results showed that the side bom branches would be induced into center branch after twice cutting back pruning. The center branches diameter, blades coarseness and weight were increased, and internodes became shorter, the quality of the fruiting cane were improved. Compared to the control, single fruit weight was increased 19.87 g by 34.69%, and spike weight was increased 55.72 g by 32.05%. The total sugar content of fruits was increased 1.23%, and extra grade quality fruit (more than 65.0 g)proportional was increased greatly, reached to 75.76%, was 2.8 times than that of the control, output value per hectare was increased 34 739.27 RMB by 61.14%.
