山地果园土层瘠薄,限制了果树根系活动范围和对养分、水分的吸收,成为制约果品产量和质量提高的重要因素。从1996年9月起,我们结合施基肥在山地果园进行了起垄栽培试验,取得了明显的增产效果。试验在卢龙县大岭店村山地果园进行,土层厚20cm左右,底为片麻岩。试验园1984年春定植,供试品种为胜利。行株距5m×4m,试验设起垄栽培和普通平栽(对照)2个处理。单株小区,5次重复。参试植株生长发育和立地条件基本一致,其它
The infertile soil in the mountain orchard limits the range of root activity of the fruit trees and the absorption of nutrients and water, which becomes an important factor that restricts the yield and quality of the fruit. From September 1996 onwards, we combined with base fertilizer in the mountain orchard Ridge cultivation experiments, and achieved significant yield increase. The experiment was carried out in the mountain orchard of Dalingdi Village, Lulong County. The soil layer was about 20cm thick and the bottom was gneiss. Test Garden in the spring of 1984 planting, test varieties for the victory. Row spacing of 5m × 4m, the test set ridge cultivation and ordinary planted (control) 2 treatment. Single plant, 5 replicates. Plant growth and development of the test site conditions are basically the same, other
