Research of Multi elements Balanced Fertilization on Staple Food Crops in Anhui

Huang Xiaolan et al(Soil & Fertilizer Institute,Anhui Academy of Agricultural Sciences,Hefei 230031)  
The multi elements balanced fertilization experiments on the staple food crops in Anhui had been conducted based on the result of the first 4 steps of the systematic approach of the soil nutrients statuts.The well designed fertilizer experiment indicated that it can significantly increase the unit yield of the staple food crops under the model of the multi elements balanced ferilization: wheat, 9 ̄20%;maize,7 ̄16% and rice,6 ̄11%,compared with the normal fertilizer model:NP or NPK,respectively.And the response of sulphur on maize was firstly observed in the northern part of Anhui.The evaluation of energy economics of fertilizers indicated that the maximum net energy return and highest yield,4 233kg/hm 2 and 53 60 GJ/hm 2 for wheat,6 764kg/hm 2 and 75 27 GJ/hm 2 for maize,6 278kg/hm 2 and 84 03 GJ/hm 2 for rice,can be obtained in the model of multi elements balanced fertilization.These meant that the market price was not reasonable and not beneficial to the production of food at present,so the suitable fertilizer model of rice,wheat and maize was the treatment of NPK+Zn,NK,and N,separately.
