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.
