摘　　要：为探究商品有机肥替代部分化肥在胡麻生产中的应用效果,以常规施肥(CK)为对照,化肥减量10%、20%、30%和100%的基础上,配施200 kg/0.067 hm^(2)商品有机肥为试验处理,研究减施化肥对胡麻生长和产量的影响。结果表明,在增施200 kg/0.067 hm^(2)有机肥的基础上,除减施化肥100%的处理减产外,其他处理与对照相比均表现为增产;仅有常规施肥减量10%、20%表现为增收且常规施肥减量10%增收最大,因此减施化肥10%在胡麻种植科学施肥管理中有一定的推广应用价值。In order to explore the practical application effect of commercial organic fertilizer replacing part of chemical fertilizer in flax production,conventional fertilization(CK)was used as the control,conventional fertilization was reduced by 10%,20%,30%and 100%,and commercial organic fertilizer of 200 kg/0.067 hm^(2) was used as the test treatment,and the effect of reduced chemical fertilizer on the growth and yield of flax was studied.The results showed that on the basis of increasing the application of 200 kg/0.067 hm^(2) organic fertilizer,except for the treatment of reducing the application of 100%chemical fertilizer,the yield of other treatments was increased compared with the control.Only 10%and 20%reduction of conventional fertilization showed income increase,and 10%reduction of conventional fertilization showed the greatest income increase.Therefore,10%reduction of chemical fertilizer has certain promotion and application value in scientific fertilization management of flax planting.
