Abstract:

To further investigate the effects of high-water-level intermittent irrigation under the application of slow-release fertilizer on rice growth characteristics, yield, soil nitrogen content, and water use efficiency, a rice planting pit experiment was conducted from May to September 2024 in the Zhanghe Irrigation District using the rice variety Zuanliangyou Chaozhan. The experiment included two irrigation modes: high-water-level intermittent irrigation (labeled W1) and conventional-water-level intermittent irrigation (labeled W2), as well as two fertilizer types: slow-release fertilizer (labeled N1) and conventional fertilizer (labeled N2). Among these, the W1N1 treatment adopted an orthogonal design with four factors and three levels, precisely controlling different gradient water levels during the rice reviving stage (labeled A), early tillering stage (labeled B), jointing and booting stage (labeled C), and heading and flowering stage (labeled D). The experimental results showed that the W1N1 treatment more significantly promoted rice tillering and plant height growth. Specifically, high-water-level control during the reviving stage and the heading and flowering stage had a greater impact on rice plant height and tillering. In terms of dry matter accumulation, the W1N1 treatment outperformed the W2N2 treatment, with high-water-level control during the heading and flowering stage having the most pronounced effect on dry matter accumulation at the yellow maturity stage. Regarding yield, the highest rice yield was observed under the A3B1C2D2N1 treatment, reaching 7 931.88 kg/hm2. Compared with the W2N2 treatment, the average yield under the W1N1 treatment was 18.17% higher. In terms of total soil nitrogen content, the W1N1 treatment increased at an average level by 11.82% compared to the W2N2 treatment. For irrigation water use efficiency, the A3B1C2D2N1 and A2B3C1D2N1 treatments showed increases of 19.18% and 13.05%, respectively, compared to the W2N2 treatment. High-water-level control during the heading and flowering stage had the greatest impact on both yield and irrigation water use efficiency. In summary, under slow-release fertilizer conditions, adopting high-water-level intermittent irrigation can promote rice plant height growth, increase tiller number, enhance dry matter accumulation, improve yield and total soil nitrogen content, and under specific water-level controls, effectively increase irrigation water use efficiency.

Key words: rice, high water-level, intermittent irrigation, slow-released fertilizer, yield, irrigation water use efficiency

摘要:

为深入探究在缓释肥施用条件下,高水位间歇灌溉对水稻生长特性、产量、土壤氮素含量以及水分利用效率的影响,2024年5月至9月,在漳河灌区以水稻品种钻两优超占为试验材料,开展水稻种植测坑试验。试验设置了两种灌溉模式:高水位间歇灌溉(W1)和常规水位间歇灌溉(W2);同时设置两种施肥类型:缓释肥(N1)和常规肥(N2)。其中,W1N1处理采用4因素3水平的正交设计,在水稻的返青期(标记为A)、分蘖前期(标记为B)、拔节孕穗期(标记为C)、抽穗开花期(标记为D)精确控制不同梯度的水位。试验结果表明,W1N1处理对水稻植株分蘖和株高增长的促进作用更为显著。具体而言,返青期和抽穗开花期的高水位控制,对水稻株高和分蘖的影响较大。在干物质积累量方面,W1N1处理的促进作用优于W2N2处理,且抽穗开花期的高水位控制对水稻黄熟期的干物质积累量影响最为突出。从产量数据来看,A3B1C2D2N1处理的水稻产量最高,达到7 931.88 kg/hm2;与W2N2处理相比,W1N1处理的平均产量高出18.17%。在土壤全氮含量方面,W1N1处理较W2N2处理平均提高了11.82%。在灌溉水利用效率上,A3B1C2D2N1处理和A2B3C1D2N1处理分别较W2N2处理高出19.18%和13.05%,且抽穗开花期的高水位控制对产量和灌溉水利用效率的影响最大。综上所述,在缓释肥条件下采用高水位间歇灌溉方式,能够促进水稻株高增长、增加分蘖数量、增强干物质积累、提高产量以及土壤全氮含量,并且在特定水位控制下,能有效提高灌溉水利用效率。
