摘要:

为了减少氮肥的施用量,提高肥料利用率,减轻对环境的污染,通过对稳定性氮肥“易及氮”与常规尿素的追肥对比,以及不同氮肥用量的对比,探索新型氮肥替代尿素追肥是否能保证水稻高产,同时探明施用不同的氮肥后氮肥利用率和土壤全氮的变化情况。试验分为稳定性氮肥和尿素的追肥对比试验以及稳定性氮肥不同用量试验两个部分。结果表明,等量的稳定性氮肥追肥效果不如尿素,增量20%施用可一定程度地增产。在整个生产过程中,稳定性氮肥施用量624 kg·hm-2时分蘖最快,产量最高,利用率也最高,同时相对尿素而言,保持土壤氮素平衡的作用更好。

Abstract:

In order to reduce the application amount of nitrogen fertilizer, improve fertilizer utilization efficiency, and reduce environmental pollution, a comparison was made between stable nitrogen fertilizer "Yiji nitrogen" and conventional urea topdressing, as well as a comparison of different nitrogen fertilizer amounts, to explore whether new nitrogen fertilizer can replace urea topdressing to ensure high rice yield. At the same time, the impact of different nitrogen fertilizers on nitrogen fertilizer utilization efficiency and changes in soil total nitrogen were also explored. The experiment was divided into two parts: a comparative trial of stable nitrogen fertilizer and urea topdressing, and a trial of different amounts of stable nitrogen fertilizer. The results showed that the top dressing effect of stable nitrogen fertilizer was not as good as urea, and an increase of 20% application can achieve a certain degree of yield increase. During the entire production process, the application of stable nitrogen fertilizer at a rate of 624 kg·hm-2 resulted in the fastest tillering, highest yield, and highest utilization efficiency. At the same time, compared with urea, it had a better effect on maintaining soil nitrogen balance.

Key words: stable nitrogen fertilizer, yield, fertilizer utilization rate, soil total nitrogen
