| 摘 要： | 在驻马店新坡村进行了小麦-玉米轮作制下的控释尿素与普通尿素掺混比例定位试验研究。结果表明:控释尿素与普通尿素掺混处理的小麦、玉米产量均以70%控释尿素+30%普通尿素处理最好,第1年和第2年的小麦产量分别比100%普通尿素处理增产17.0%和21.1%,玉米产量分别比普通尿素处理增产16.2%和16.2%;氮肥利用率与产量结果一致,均以70%控释尿素+30%普通尿素处理最高,分别为53.9%和54.5%。

| Abstract: | The location tests of different blend ratio between controlled-release urea and conventional urea in wheat-corn crop rotation system in Xinpo Village Zhumadian city are studied. The results show that： the yield with the blend ratio between 70% controlled-release urea and 30% conventional urea is the best. In the first and second year, the yields of wheat increase 17.0% and 21.1% compared with the 100% conventional urea test, the yields of corn increase 16.2% and 16.2% compared with the conventional urea test. The same results of nitrogen utilization efficiency and yield are the highest on 70% controlledrelease urea and 30% conventional urea treatment, respectively, 53.9% and 54.5%. |
