%X <span style=\"font-size:14px;\">通过钙镁磷肥不同用量试验来研究P2O5对烟叶质量的影响，试验采用随机区组设计，4个处理3次重复，12个小区，亩施钙镁磷肥15 kg (T2)、30 kg (T3)、45 kg (T4)与空白对照(T1)不同处理。试验结果表明：在衡阳县黄泥田土壤上种植烟叶，P2O5施用量建议在8.1~8.9 kg/亩之间，既能促进烟叶旺盛生长(株高、茎围、节距、叶面积和有效叶片数表现最优)，又能提高产量，增加中上等烟的比例，提高品质，增加农民收入。</span><br />
<span style=\"font-size:14px;\">The effect of P2O5 on the quality of tobacco leaves was studied through the experiment of different amounts of calcium magnesium phosphate fertilizer. The experiment adopted a randomized block design, four treatments were repeated three times, and 12 plots were applied with calcium magnesium phosphate fertilizer 15 kg (T2), 30 kg (T3), 45 kg (T4) and blank control (T1). The results showed that when tobacco was planted on the yellow mud soil in Hengyang County, the P2O5 application rate was suggested to be between 8.1~8.9 kg/mu, which could not only promote the vigorous growth of tobacco (plant height, stem circumference, pitch, leaf area and effective leaf number were the best), but also increase the yield, increase the proportion of medium and top grade tobacco, improve the quality and increase the income of farmers.</span>
