为治理、开发黄淮海平原风沙化土地,3年间,从国内外引入149个果树品种,建果园15.3hm2。历时7年,选择出良种28个,有苗百万株,推广、辐射面积0.66hm2。研究表明:在现有条件下,本区采用引进选择、试验示范、推广辐射的办法,进行大穴栽植,截断淤积层,矮化密植,四季修剪,植物生长剂调控树体,少量、多次、浅施肥料,增施有机肥,间作留茬,冬春少耕、免耕,早防病虫害等一整套果树栽培、管理技术,是发展黄淮海风沙化地区果林业的一条快速、可靠、有效的方法。
In order to harness and develop the wind-desertification land in the Huang-Huai-Hai Plain, in the three years, 149 fruit trees were introduced from home and abroad to build 15.3 hm2 of orchards. It took 7 years to choose 28 varieties of seedlings and 1 million seedlings to promote and radiate an area of 0.66hm2. The research shows that under the existing conditions, the method of introducing, selecting, experimenting, demonstrating and popularizing radiation is adopted in this area to carry out large-hole planting, truncated siltation, dwarfing dense planting, pruning in four seasons and plant growth regulating agent, A set of fruit tree cultivation and management techniques with shallow fertilizers, organic fertilizers, intercropping stubble, winter and spring less tillage, no-tillage and pest control diseases are a fast, reliable and effective way to develop fruit trees and forestry in the Huang-Huai sea-breeze desertification area method.
