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.
