摘　　要：通过旱作农业区不同施肥模式下的春油菜小区试验,对不同施肥模式下春油菜生物学性状、产量及植株养分含量观测、测定和分析,结果表明,不同的施肥模式对春油菜的生长发育产生不同的影响,一次性施入尿素329.0 kg/hm2、三料过磷酸钙124.5 kg/hm2、氯化钾75.6 kg/hm2、有机肥1 700.6 kg/hm2,采用垄膜沟植栽培使产量达到4 425 kg/hm2,是较理想的栽培模式;基施尿素224.5 kg/hm2、三料过磷酸钙194.5 kg/hm2、氯化钾93.4 kg/hm2、有机肥1 256.0 kg/hm2,在蕾苔期追施尿素75.6 kg/hm2,可以满足春油菜生育期对养分的需要,产量达到4 366 kg/hm2,是较为合理的露地施肥模式。Through the field plot experiment of spring oilseed rape by different fertilizing models in dry-land agricultural regions,observe determination and analysis for yield of spring oilseed rape,biological features and nutrient content of plant by different fertilizing models.The results indicated that,different fertilizing had exert different impact models to growth and development of spring oilseed rape.Fertilizer urea 329.0 kg/hm2,treble superphosphate 124.5 kg/hm2,potassium chloride 75.6 kg/hm2,organic fertilizer 1 700.6 kg/hm2 all at once,yield could achieve 4 425 kg/hm2 by adopting ridge and film trend-planting cultivation,was a desirable cultivation models.Basal applicate urea 224.5 kg/hm2,treble superphosphate194.5 kg/hm2,potassium chloride 93.4 kg/hm2,organic fertilizer1 256.0 kg/hm2,cross dressing urea 75.6 kg/hm2,it could meet of the demands nutrient for spring oilseed rape in growth and development period,yield achieve 4 366 kg/hm2,was more reasonable exposed soil fertilizing models.
