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%。
In the new village of Zhumadian wheat - corn rotation under the system of controlled release urea and ordinary urea blending ratio of positioning test. The results showed that the yields of wheat and corn blended with controlled release urea and ordinary urea were the best with 70% controlled release urea and 30% normal urea, respectively. The yields of wheat in the first year and the second year were respectively 100% and 100% The yield of maize was increased by 17.0% and 21.1% respectively, and the yield of maize was increased by 16.2% and 16.2% respectively compared with that of common urea. The utilization of nitrogen fertilizer was the same as that of the yield. Both were treated with 70% controlled release urea and 30% ordinary urea, which were 53.9% and 54.5% %.
