A kind of pruning method of blueberry

Abstract

The invention discloses a blueberry trimming method which comprises the following steps: in the trimming period which is any other growing period except the blueberry ripening fruiting period, firstly, trimming blueberry branches with the diameter smaller than 4 mm and the length smaller than 15 cm, and reserving blueberry branches with the diameter greater than 4 mm and the length greater than 15 cm; secondly, pruning away branches growing towards the internal parts of plants, reserving 2-4 base-growing branches, and applying a coating on all the incisions of the branches to promote wound healing and prevent infection of viruses and fungi; finally, disinfecting a pruning knife after the trimming of each plant is finished. According to the invention, the trimming period for operation is long, and the distribution space of blueberry branches and tendrils is reasonable, sunlight is fully utilized, and the fruit quality is guaranteed through effective trimming; branches are selectively reserved or removed, and the flower bud quantity is controlled, so that the nutrition consumption is reduced, the reproductive growth and vegetative growth of the whole plant are balanced, the problem that produced blueberries are high in quantity and small in fruits is effectively solved, and the quality and yield of blueberries are improved.
