樟子松是东北地区主要速生用材、防护和“四旁”绿化的优良树种之一,为了进一步提高造林成活率和促进幼树生长,试验组用化工部沈阳化工研究院提供的新产品吲哚丁酸(IBA)处理樟子松苗木后,进行造林试验,筛选对樟子松苗木的最佳浓度和浸泡时间,观测试验效果。试验概况药剂来源:吲哚丁酸(IBA)由化工部沈阳化工研究院农药一室激素组提供。试验地点:国营东辽县渭津林场方地林班,面积三十三亩。土壤为暗棕色森林土。坡向为西坡、西南坡。栽植株行距为1.0×1.5米。
Pinus sylvestris is one of the fine tree species in northeastern China that is mainly used for fast growing, protection and “greening around”. In order to further improve the survival rate of afforestation and promote the growth of saplings, the experimental group was treated with the new product Indole-D After the seedlings of Pinus sylvestris L. were treated with acid (IBA), the afforestation experiment was carried out to select the optimum concentration and soaking time of Pinus sylvestris var.mongolica seedlings. The effect of the test was observed. Test Overview Pharmacy Source: Indole butyric acid (IBA) by the Ministry of Chemical Industry Shenyang Institute of Chemical pesticides a room hormone group to provide. Test Location: State-owned Weidong forest farm in Dongliao County forest classes, an area of thirty-three acres. Soil is dark brown forest soil. Slope for the west slope, southwest slope. Planting row spacing of 1.0 × 1.5 meters.
