1987年下半年,河北林学院有两项科研成果通过技术鉴定。 一、大金星山楂嫩枝插条提高成活率快速育苗技术的研究 大金星山楂系我国特产果树,是河北的主栽品种之一。它的果实品质优良,有较高的营养价值和医疗价值。多年来因插条生根困难,生产上多采用种子育苗,以致苗木生产周期较长。大金星山楂嫩枝插条育苗的研究,过去虽曾取得某些进展,但插条成活率仍然不高。在巳有研究的基础上,河北林学院和邢台县将军墓镇政府等单位协作,经过1983—1987年的探索,在系统地试验和观察了插穗类型、植物生长调节物质的种类与浓度、插条深度以及环境
In the second half of 1987, two scientific research achievements of Hebei Forestry College passed technical appraisal. First, the Venus Hawthorn shoots cuttings to improve the survival rate of rapid breeding technology research Venus Hawthorn Department of China’s specialty fruit trees, Hebei is one of the main cultivars. Its excellent fruit quality, high nutritional value and medical value. Over the years due to the difficulties of cuttings, the production of seedlings used more seeds, resulting in longer production cycle seedlings. Da Venus hawthorn shoot cutting nursery research, although some progress has been made in the past, but the survival rate of cuttings is still not high. Based on the existing research, Hebei Forestry College and Xingtai County General Tomb Town government and other units, through the exploration of 1983-1987, we systematically tested and observed the types of cuttings, plant growth regulators and concentrations, Depth and environment
