- W2348372710 abstract "[Objective] The study aimed to discuss the effects of soil testing and formula fertilization on maize yield and fertilizer utilization efficiency.[Method] On the soil with different types in main maize-planting areas of Jilin Province,with the local main popularizing varieties as the tested varieties,the contrast tests were set up between the soil testing and formula fertilization and the farmer custom fertilization to study the effects of soil testing and formula fertilization on maize yield components,maize yield,fertilizer benefit and fertilizer utilization efficiency.[Result] On the different soils in east,middle and west areas in Jilin Province,the maize yield components including ear length,bald tine and grains per ear in the treatment by formula fertilization were better than that by the farmer custom fertilization and the 1 000 grains weight and grains per ear were increased by 1.6%-6.7% and 3.8%-8.0% resp.Compared with the farmer custom fertilization,the soil testing and formula fertilization could increase the maize yield obviously,the maize yield was increased by 122-1 228 kg/hm2,the income was increased by 398-1 457 yuan/hm2 and the fertilizer utilization efficiency was increased by 0.22%-13.26%,indicating that the fertilizer dosage and their matching ratio in the soil testing and formula fertilization were basically rational.[Conclusion] Soil testing and formula fertilization could not only realize the objective of increasing maize yield,saving the cost and increasing the efficiency,but also improve the fertilizer utilization efficiency highly." @default.
