吉林省西部地区盐碱地配方施肥对玉米产量和肥料吸收的影响

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。

Effects of Formulation Fertilization on Maize Yield and Fertilizer Absorption in Saline and Alkaline Lands of Western Region in Jilin Province Province

Taking'Zhengdan 958'as test materials and using 5 formulation fertilization,maize yield and fertilizer absorption in saline and alkaline lands of western region in Jilin province were studied.The results showed that the maize yield could be increased by the additional application of K,Zn,Se and organic fertilizer.The effect of additional application of N90P75K60Zn15 + organic fertilizer 45 000 kg/hm2 was the best.The additional application of K fertilizer significantly improved N absorbability of maize,the additional application of Se fertilizer improved P absorbability of maize,the additional application of Zn fertilizer reduced the absorbability of maize to P,the additional application of Zn fertilizer improved the absorbability of maize to K,and the additional application of Se fertilizer decreased the absorbability of maize to K.
