摘要：

本研究旨在探讨施氮量对胡麻产量和千粒重的影响，为胡麻施氮管理提供依据。通过收集2023年以前21篇文献116条数据进行Meta分析，将数据按照试验年份、试验地点、土壤类型、土壤有机质含量、土壤碱解氮含量、土壤速效磷含量、土壤速效钾含量和土壤pH进行分组，以不施氮肥为对照组，探究施氮对胡麻产量和千粒重影响的综合效应。研究结果表明：施氮量在120~150 kg/hm2时，胡麻产量(22.14%)和千粒重(4.55%)的效应值最高；在2010—2013年施氮对胡麻产量(20.44%)的效应值最高；施氮对甘肃胡麻产量(23.17%)和千粒重(5.23%)的效应值最高；沙壤土施氮对胡麻产量(23.30%)和千粒重(5.63%)的效应值最高；在土壤碱解氮含量>50 mg/kg、土壤有机质含量<10 g/kg、土壤速效磷含量>25 mg/kg、土壤速效钾含量100~200 mg/kg和土壤pH 8~8.5时胡麻施氮增产效应最高，分别为19.42%、20.22%、21.38%、20.10%、20.22%。在土壤碱解氮含量<50 mg/kg、土壤有机质含量<10 g/kg、土壤速效磷含量15~25 mg/kg、土壤速效钾含量100~200 mg/kg和土壤pH 8~8.5时施氮对胡麻千粒重的提升效应最高，分别为5.77%、6.33%、7.60%、5.31%、4.73%。施氮量在120~150 kg/hm2时，胡麻产量和千粒重提升最高。本试验研究结果可为今后不同生产条件下胡麻施氮增产和千粒重提升提供参考。

Abstract:

To explore the effect of nitrogen application on yield and thousand-grain weight of flax, and provide a reference for flax nitrogen application management, a meta-analysis was conducted using 116 pieces of data from 21 papers collected up to 2023. The data were grouped according to the test year, test location, soil type, soil organic matter content, soil alkali hydrolyzed N content, soil available P content, soil available K content and soil pH value. The comprehensive effect of nitrogen application on flax yield and thousand-grain weight was explored, with no nitrogen fertilizer application serving as the control group. The research results indicated that when the nitrogen application was between 120-150 kg/hm2, the effect values on flax yield (22.14%) and thousand-grain weight (4.55%) were the highest; the effect value of nitrogen application on flax yield (20.44%) was the highest from 2010 to 2013; the effect values of nitrogen application on Gansu flax yield (23.17%) and thousand-grain weight (5.23%) were the highest; the effect values of nitrogen application on flax yield (23.30%) and thousand-grain weight (5.63%) were the highest in sandy loam soil. When soil alkali hydrolyzed N content was >50 mg/kg, soil organic matter content was <10 g/kg, soil available P content was >25 mg/kg, soil available K content was 100-200 mg/kg, and soil pH value was 8-8.5, the nitrogen application of flax had the highest yield-increasing effect, which were 19.42%, 20.22%, 21.38%, 20.10% and 20.22%, respectively. When soil alkali hydrolyzed N content was <50 mg/kg, soil organic matter content was <10 g/kg, soil available P content was 15-25 mg/kg, soil available K content was 100-200 mg/kg, and soil pH value was 8-8.5, the nitrogen application had the highest effect on improving the thousand-grain weight of flax, which was 5.77%, 6.33%, 7.60%, 5.31% and 4.73%, respectively. When the nitrogen application rate was between 120-150 kg/hm2, the increases in flax yield and thousand-grain weight were the highest. The research results of this experiment could provide a reference for increasing yield and thousand-grain weight of flax under different production conditions in the future.
