【摘要】 在皖南香料烟产区硼素贫乏的土壤上采用基施硼砂15kg/hm2和叶面喷硼7.5kg/hm2两种方法增硼,以不基施也不叶面喷施硼砂为对照,结果表明,施硼能够促进烟株生长,提高上等或上中等烟比例和均价,增产,增值,改善烟叶内在品质。其中以叶面喷硼方法效果较好,经济效益和质量效益都十分明显。更多还原

【Abstract】 In the present study, two ways for increasing the content of boron were applied: borax as the basic fertilizer at 15kg/hm 2 and boron as foliage fertilizer 7.5kg/hm 2 of aromatic tobacco plant in soil in short boron supply in south Anhui Province, with soil not treated as above as control. The result showed that fertilizing boron promoted plant growth, raised the ratio of high class leaves or high-middle class leaves and mean value,increased the yield and value, and improved leaf quality.As compared to that of basic fertilizer application, the effect of foliage fertilizer was better,and economic effect and quality effect were both obvious.更多还原
