Study on the Effect of Formula Fertilization Maize

The purpose was to identify the field usage effect of formula fertilization by soil testing on maize in Huaiyuan county.Based on the test result of soil nutrient in the project area in Huaiyuan county,the fertilizer-needing law for maize and fertilizer effect,the maize specific fertilizer(basic fertilizer type) with total nutrient content of 36%(N-P2O5-K2O=16-8-12) was produced.The field fertilizer effect experiment was conducted in the project area in the summer of 2006.Compared with normal fertilization treatment,in formula fertilization for maize treatment,the bigger the spike was,the more 49 grains per spike was;18 g 1 000-seed weight was and the yield increased 410 kg/hm2(5.5%)and the famer income enhanced 514.50 yuan/hm2.The maize formula fertilization with total nutrient content of 36% for maize performed the better effect of cost reducing and income increasing,being quite scientific and reasonable.
