Abstract

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
