摘　　要：探究不同施磷量对胡麻籽粒蛋白质和金属元素含量的影响,为构建磷肥高效管理提供依据。通过2018和2019年连续2年大田试验,设置5个施磷水平(0、40、80、120、160 kg P_(2)O_(5)·hm^(-2)),3个品种(陇亚杂1号、陇亚14号和张亚2号)两因素随机区组试验,研究不同磷水平对胡麻籽粒产量,籽粒蛋白质、钾、钙、钠、镁含量的作用效果。结果表明,随施磷量增加,胡麻籽粒产量、籽粒钾、钙、镁含量不同程度增加;相比不施磷,施磷处理籽粒产量、籽粒钾、钙、镁含量,分别平均提高17.6%、11.6%、17.6%和12.5%;籽粒蛋白质和钠含量不受磷影响。综合考虑胡麻籽粒产量、籽粒钾、钙、镁含量和生态环境,该区域施磷80 kg P_(2)O_(5)·hm^(-2)较佳,可协同增加胡麻籽粒产量及籽粒钙、镁含量;降低环境风险,减少碳排放。To explore phosphorus(P)rate effect on protein and metal content of flaxseed,and to provide a basis for establishment high efficient P fertilizer management,field experiments were conducted in 2018 and 2019 with 2 factors randomized block by 5 P levels(0,40,80,120,160 kg P_(2)O_(5)·hm^(-2))for 3 cultivars(Longyaza 1,Longya 14 and Zhangya 2).Seed protein,potassium,calcium,sodium and magnesium contents of flaxseed were investigated.Results showed that flaxseed yield,seed potassium,calcium and magnesium contents improved in different degrees with P application rate.Compared with no P,average seed yield,seed potassium,calcium and magnesium contents increased 17.6%,11.6%,17.6%and 12.5%respectively.Phosphorus did not affect seed sodium and protein contents.Considering yield,seed potassium,calcium and magnesium contents between years,P rate of 80 kg P_(2)O_(5)·hm^(-2) was the most appropriate,which synergistically increased yield,flaxseed calcium and magnesium contents,and also reduced environmental risks by excess P fertilizer.
