吉林省镇赉县土壤有效硼含量在0～138ppm,平均含量在0.50ppm,其中55％ 的样本含硼量低于临界值(0.50ppm)。甜菜是喜硼作物,如果严重缺硼会引起生理病害(心腐病)。潜在性缺硼不发病时,施硼肥亦会增产,为了指导大面积生产,我们进行了甜菜根外追硼肥试验、结果表明,增产增糖效果显著。试验在镇赉县五棵树镇进行,试验田面积为2000m~2。甜菜品种是进口丹麦单粒种。试验田在早春顶浆三犁川打垄整
The effective boron content of soil in Zhenlai County of Jilin Province is between 0 and 138 ppm with an average content of 0.50 ppm, of which 55% of the samples have a boron content below the critical value (0.50 ppm). Sugar beet is hi boric crop, if serious boron deficiency will cause physiological disease (heart rot). Potential lack of boron is not affected, the application of boron fertilizers will increase production, in order to guide large-scale production, we conducted a beet root outside the boron recovery test, the results show that the effect of increasing sugar production significantly. The experiment was carried out in Wukeshu Town, Zhenlai County, with an experimental plot area of 2000m ~ 2. Beet varieties are imported single species of Denmark. Experimental field in early spring top three Sichuan hit Ridge Ridge
