| 摘 要： | 【目的】筛选出适宜新疆加工番茄产量、品质和氮素吸收利用提高的普通尿素和缓释尿素配比。【方法】以普通尿素和缓释尿素为供试材料,设置9种试验处理,以不施氮为对照,研究普通尿素和缓释尿素不同配比对加工番茄干物质积累、产量、氮累积和氮素利用率的影响。【结果】与不施氮处理相比,施氮显著提高了加工番茄的干物质积累、产量和氮素利用率,100%等氮量时,70%缓释尿素+30%普通尿素花期追施处理效果最好,80%等氮量时,60%缓释尿素+20%普通尿素花期追施+20%普通尿素果期追施效果最好,且80%等氮量更优于100%等氮量。【结论】采用80%等氮量时,60%缓释尿素+20%普通尿素花期追施+20%普通尿素果期追施效果最优,既可以增加加工番茄产量,又可实现氮素的高效利用。

| Abstract: | 【Objective】 In order to solve the problem of low fertilizer utilization rate of processing tomatoes in China, the fertilizer proportion suitable for the improvement of yield, quality and nitrogen absorption and utilization of processing tomatoes in Xinjiang was screened out. 【Method】 The effects of different ratios of common urea and slow-release urea on dry matter accumulation, yield, nitrogen accumulation and nitrogen use efficiency of processed tomato were studied with 9 treatments and no nitrogen application as the control.【Result】 The results showed that compared with non-N application, N application significantly increased dry matter accumulation, yield and nitrogen utilization rate of processing tomatoes. 70% slow-release urea + 30% common urea had the best effect at 100% equal nitrogen level, and 60% slow-release urea + 20% common urea had the best effect at 80% equal nitrogen level at flowering stage and 20% common urea had the best effect at fruit stage, and 80% equal nitrogen level was better than 100% equal nitrogen. 【Conclusion】 Under the experimental conditions, 60% slow-release urea + 20% ordinary urea topdressing at flowering stage + 20% ordinary urea topdressing at fruit stage with 80% equal nitrogen content had the best effect, which could not only increase the yield of processed tomato, but also realize the efficient utilization of nitrogen. |
