【摘要】 通过田间小区试验,研究了喷施硼肥对烤烟的影响。结果表明:相比对照,每株喷施浓度为0.1%的硼砂溶液200 mL,可使烟株最大叶长、叶宽和株高分别显著增加9.05、2.34和1.62 cm,使烤后烟叶化学成分更协调,同时,烟叶产量和产值显著提高212.16 kg/hm~2、6 829.2元/hm~2,中上等烟比例显著提高1.87个百分点,均价显著提高0.73元/kg,经济性状更好。更多还原

【Abstract】 Through the field plot experiment, the effect of boron fertilizer on flue-cured tobacco was studied. The results showed that compared with the CK, each tobacco plant sprayed with 200 ml of 0.1% borax solution got a significant increase of 9.05 cm, 2.34 cm and 1.62 cm, respectively in the maximum leaf length, leaf width and plant height, and chemical composition of the flue-cured tobacco leaves became more harmonious; the yield and output value of tobacco leaves remarkably increased by 212.16 kg/hm2 and 6 829.2 yuan/hm2, respectively; the proportion of superior-and medium-grade tobacco leaves significantly increased by 1.87 percentage points, and the average price notably increased by 0.73 yuan/kg.更多还原
