Study on fertilizer effect of spring oilseed rape by different fertilizing models in Dry-land agricultural regions
Year: 2011
Type: article
Abstract: 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.
