摘要/Abstract

摘要： 【目的】 研究不同配肥模式对滴灌棉花氮素吸收利用规律。【方法】 采用大田单因素随机区组方法,设置4种施肥方式,第1种为1/3时间施肥,1/3时间浇水,1/3时间施肥、第2种为1/2时间施肥,1/4时间浇水,1/4时间施肥、第3种为1/4时间施肥,1/4时间浇水,1/2时间施肥、第4种为1/4时间施肥,1/2时间浇水,1/4时间施肥,分别记为W₁、W₂、W₃、W₄。研究滴灌条件下不同配肥模式棉花全氮含量以及氮素在各器官中的分布积累特征。【结果】 (1)不同配肥模式下滴灌棉花植株平均全氮含量表现为W₁＞W₂＞W₃＞W₄;(2)不同器官滴灌棉花全氮含量在表现为叶＞花蕾＞铃＞茎;(3)不同配肥模式下滴灌棉花的氮肥农学利用率和氮肥偏生产力都表现为W₁＞W₃＞W₂＞W₄。【结论】 棉花氮素吸收利用和产量最高的N-W-N模式下,最优的配肥时段是W₁(1/3时间浇水,1/3时间施肥,1/3时间浇水)处理。

Abstract: 【Objective】 To study the nitrogen absorption and utilization of cotton under drip irrigation with different fertilizer modes. 【Methods】 Four kinds of fertilization methods were set up in the field single-factor randomized block test method. The first type was fertilized in 1/3 time, watered in 1/3 time, fertilized in 1/3 time, and the second type was 1/2 time fertilization, 1/4 time watering, 1/4 time fertilization, 3rd type 1/4 time fertilization, 1/4 time watering, 1/2 time fertilization, 4th type 1/4 time fertilization, 1/2 time watering, 1/4 time fertilization, and they were respectively recorded as W₁, W₂, W₃ and W₄. During the whole process, the total nitrogen content of cotton and the distribution and accumulation of nitrogen in various organs under different drip irrigation conditions were studied. 【Results】 The results showed that (1) the average total nitrogen content of cotton plants under drip irrigation was W₁>W₂>W₃>W₄; (2) the total nitrogen content of cotton under different organs was expressed as leaf > flower bud > boll > stem; (3) The agronomic efficiency of nitrogen fertilizer and the partial productivity of nitrogen fertilizer in drip irrigation cotton under different fertilizer allocation patterns were: W₁>W₃>W₂>W₄. 【Conclusion】 The best NWN mode for nitrogen absorption and utilization and yield of cotton The fertilizer distribution period is W₁ (1/3 time watering, 1/3 time fertilization, 1/3 time watering).
