近年来,许多地方结合农田基本建设,营造了农田林网,要使新植林带迅速长起来,造林后最初几年的抚育管理是非常重要的。为了摸索有效的抚育措施,我们在辽宁省法库县丁家房公社对杨树新林带采取培垅抚育的效果进行了调查。调查林带在法库县丁家房公社西部方田内,土壤为冲积草甸土,造林地原为耕地,地下水位1.0—1.5米。1975年春造林,造林前机翻整地。林带为5行,1.0×1.5米株行距,栽植未经剪枝的2年生北京杨大苗,栽植深度35—40厘米。林带造完后,立即用锹分别将各行行间表土培向行内,最后培成高0.5米、宽
In recent years, in many areas, the farmland infrastructures have been combined to create a farmland forest network. To rapidly grow new plantation belts, tending and management in the first few years after afforestation are very important. In order to explore effective tending measures, we investigated the effect of nurturing and nurturing young poplar trees in Dingjiafang commune, Faku County, Liaoning Province. Investigate the forest belt in Faku County Dingjiafang commune Western square, the soil is alluvial meadow soil, afforestation formerly arable land, groundwater level 1.0-1.5 meters. In the spring of 1975 reforestation, reforestation before the reforestation. Forest with 5 rows, 1.0 × 1.5 meters spacing, planted 2-year-old unmanaged Beijing Yang seedlings, planting depth 35-40 cm. After the forest belt is finished, use the shovel to spread the topsoil to the inside of each line, and finally cultivate a height of 0.5m and width
