为解决梨园的风灾问题,我们借鉴了国外设施栽培的经验,在13.3多hm~2、高接为新兴、丰水、廿世纪的梨树上空搭建了大棚架,取得良好效果。现将梨园的棚架栽培介绍如下。 一、梨园棚架的建立 在树行间设立柱,间距为20m×20m(平均5株树1根立柱),支柱是由长、宽、高为20cm×20cm×230cm的钢筋水泥柱及焊接其上的铁管组成。支柱上的铁管直径为5cm,长度为360cm。中间及上部焊有铁环,用于吊挂油丝绳(多股铁丝扭成的铁绳),防止架面下沉。大棚的 To solve the problem of wind disaster in pear orchards, we draw on the experience of foreign facility cultivation and set up a large scaffolding frame over 13.3 hectares of hm-2 and high access roads for emerging, abundant and 20th-century pear trees and achieved good results. Pear cultivation is now introduced as follows. A pear garden scaffolding set up between the trees in the column, spacing of 20m × 20m (an average of five trees a column), the pillar is by the length, width and height of 20cm × 20cm × 230cm reinforced concrete columns and welding Iron pipe on the composition. The iron pipe on the pillar has a diameter of 5 cm and a length of 360 cm. The middle and upper welded iron ring, used to hang the oil wire rope (multi-wire twisted into the iron rope), to prevent surface sinking. Greenhouses
