以郑单958玉米品种为试验材料,在吉林省西部地区盐碱地采用5个配方施肥处理,针对玉米的产量和玉米对肥料的吸收情况进行试验。结果表明:在农民传统施肥的基础之上,添加一定量的K肥、Zn肥、Se肥、有机肥都能提高玉米产量,以配方N90P75K60Zn15+有机肥45 000 kg/hm2最为理想。配方中增加K肥能显著增加玉米对于N的吸收,配方中加入Se肥能促进玉米对于P的吸收,加入Zn肥反而抑制了玉米对于P的吸收,配方中添加Zn肥有利于玉米对于K的吸收,而添加Se肥会抑制玉米对于K的吸收。
Taking Zhengdan 958 maize variety as test material, five formulas fertilization treatments were applied to saline-alkali land in the west of Jilin Province to test the yield of maize and the absorption of fertilizer by maize. The results showed that adding a certain amount of K fertilizer, Zn fertilizer, Se fertilizer and organic manure can increase corn yield based on the traditional fertilization of peasants, and the most ideal is the formula N90P75K60Zn15 + organic fertilizer 45 000 kg / hm2. Adding K fertilizer to the formula can significantly increase the absorption of N for maize, adding Se fertilizer to the formula can promote the absorption of P for maize, but adding Zn fertilizer inhibits the absorption of P for maize, and the addition of Zn fertilizer to the formula is beneficial for K Absorption, while adding Se fertilizer will inhibit the absorption of corn K.
