近年来,由于延安地区大量商品果的集压,加之新型果园发展缓慢,原有果园管理粗放,逐渐退化,产量、品质逐年下降。为了充分利用已建果园,使其充分发挥生产能力,尽量多的解决当地果品的自给问题,有必要对当地现有果园进行技术性管理——整形和修剪。以促进光合作用,增加碳水化合物的形成,从而提高果品的产量和质量。
In recent years, due to the accumulation of a large number of commodity fruits in Yan’an and the slow development of new orchards, the original orchard management has been extensively degenerated and the output and quality have been declining year by year. In order to make full use of the existing orchards so that they can give full play to their productive capacity and try their best to solve the problem of self-sufficiency of local fruits, it is necessary to carry out technical management on the existing orchards in the area - shaping and pruning. To promote photosynthesis, increase the formation of carbohydrates, thereby enhancing fruit yield and quality.
