核桃密闭园密度干预措施

Density Intervention Measares of Walnut Closed Garden

早实核桃一般要采取规模化建园、集约化生产,树体年生长量较大,进入盛果期后,树体高大密闭,会导致生产能力下降,病虫危害加剧,树体生长势衰落,给日常管理带来不便。对此,本文提出要对密闭园进行密度干预,通过对盛果期核桃园植株间伐、植株改接、换头培养用材品种或移栽另新建园等方式,进行科学改造,实现果园提质增效和产业的可持续发展。

Early-bearing walnut is a large-scale garden and intensive production, and the annual growth of the tree body is large. Entering the peak fruit stage, the tree body is tall and closed, the ability of continuous quality improvement and efficiency enhancement is reduced, the harm of pests and diseases is aggravated, the growth potential of the tree body is declining, and it brings inconvenience to daily operation and management.In view of this phenomenon, this paper proposed to re-plan the closed orchard, through thinning, plant grafting,replacing cultivars for cultivation or transplanting some of the plants in the orchard into a new orchard in the peak fruit period, to achieve the improvement of quality and efficiency of the orchard and the sustainable development of the industry.
