| 摘 要： | 为了验证玉米测土配方肥在怀远县的田间使用效果。基于怀远县测土配方施肥项目区土壤养分测试结果,根据玉米需肥规律和肥料效应,生产出了总养分含量36%(N-P2O5-K2O=16-8-12)的玉米专用肥(基肥型),并于2006年夏季在怀远县测土配方施肥项目区进行了田间肥效试验。玉米配方肥处理较常规施肥处理果穗粗大,穗粒数多49个,千粒重高18 g,增产410 kg/hm2,增产率5.5%,增收514.50元/hm2。总养分含量36%的玉米配方肥表现出较好的节本增收效果,是比较科学合理的。 |

| Abstract: | 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. |
