硼是作物生长发育所必需的微量营养元素之一。缺硼会引起一系列的生理病害、造成减产。土壤普查结果表明:我县土壤普遍缺硼。为摸清硼肥在葡萄上的肥效及其施用技术,从1984年起,我们在大泽山、青杨、昌里三处乡镇进行了多点试验、示范,并在此基础上进行了大面积推广。到1986年全县葡萄园累计施硼面积4.0万亩,平均每年1.33万亩,是全县结果葡萄园面积的80％,取得了明显的增产效果和经济效益。现将结果整理如下:
Boron is one of the micronutrients necessary for crop growth and development. Boron deficiency will cause a series of physiological diseases, resulting in reduced production. Soil census results show that: my county generally lack of boron soil. In order to find out the effect of boron fertilizer on grapes and its application technology, since 1984, we carried out a number of experiments and demonstrations in Dazeshan, Qingyang and Changli townships, and on this basis conducted a large Area promotion. By 1986 the county’s total area of 40,000 acres of boron fertilizer facilities, an average of 13,300 mu per year, is the county results of the vineyard area of 80%, and achieved significant increase yield and economic benefits. The results are now organized as follows:
