添加腐殖酸和微量元素的套餐施肥方案对马铃薯产量的影响

Effects of Formula Fertilization Scheme Adding Humic Acid and Trace Elements on Potato Yield

为验证含腐殖酸、微量元素锌和硼的心连心马铃薯套餐肥对内蒙古乌兰察布地区马铃薯生产的影响,以常规施肥为对照,开展了大田小区试验。结果表明:与常规施肥处理相比,心连心马铃薯套餐肥处理的马铃薯产量提高了8.69%;商品率由66.39%升至84.54%,收益增幅62.79%;大薯率由42.86%升至63.41%;套餐肥中的腐殖酸和微量元素可以增强马铃薯抵抗不良环境的抗性和延缓叶片衰老。心连心马铃薯套餐肥可以提高乌兰察布地区马铃薯的产量和商品率,增加了农户的种植收益。

In order to verify the effect of Xinlianxin potato formula fertilizer containing humic acid, trace elements zinc and boron on potato production in Ulanqab area of Inner Mongolia, a field experiment is carried out with conventional fertilization as a control. The results show that compared with the conventional fertilization treatment, the potato yield of Xinlianxin potato formula fertilizer treatment increases by 8.69%. The commodity rate increases from 66.39% to 84.54%, and the income increases by 62.79%. The large potato rate increases from 42.86% to 63.41%. The humic acid and trace elements in the formula fertilizer can increase potato′s resistance to adverse environment and delay leaf senescence. The Xinlianxin potato formula fertilizer can increase the yield and commodity rate of potatoes in Ulanqab area, and increase planting income of farmers.
