为证实稀土海泡石化肥添加剂的增产效果,于2010～2011年使用不同肥料添加剂对玉米进行田间试验。结果显示:2010年和2011年稀土海泡石化肥添加剂处理区比海泡石化肥添加剂的对照区分别增产10.62%和11.13%;比硝酸稀土化肥添加剂的对照区分别增产28.92%和30.09%;比无化肥添加剂的对照区分别增产29.36%和30.95%。施用硝酸稀土化肥添加剂的对照区比无化肥添加剂的对照区只增产0.34%和0.66%。这说明硝酸稀土直接施用土壤增产效果不够明显,而稀土海泡石化肥添加剂能明显提高玉米产量,有一定的推广价值。
In order to confirm the stimulation effect of rare earth sepiolite fertilizer additives, field experiments on maize were conducted using different fertilizer additives from 2010 to 2011. The results showed that compared with the control area of sepiolite fertilizer additives, the treatment area of REE increased 10.62% and 11.13% respectively in 2010 and 2011, and increased 28.92% and 30.09% respectively compared with the control area of REE additive; The control area without fertilizer additives increased yield by 29.36% and 30.95% respectively. The control zone with the Rare Earth Nitrogen Fertilizer additive only increased 0.34% and 0.66% of the control zone without the fertilizer additive. This shows that the direct application of rare earth nitrate soil yield increase effect is not obvious enough, and rare earth sepiolite fertilizer additives can significantly improve the yield of corn, have some promotional value.
