中文摘要: |
内蒙古农业大学教学农场大田设施磷与不施磷两处理,分析研究春小麦不同生育期体内的氮、磷、钾含量、吸收量,干物质积累量和生物产量。结果表明,乳熟-蜡熟阶段是春小麦养分吸收和生物产量积累的最快时期,磷可提高植株体内氮、磷养分浓度,对其他养分浓度影响不是很明显。磷素有利于干物质积累,可以增加春小麦生物产量和籽粒中氮、磷含量,但对钾素的影响不明显。因此,在制定施肥方案时,应重视氮、磷、钾的合理配合,以满足春小麦"高产、优质、高效"生产的营养需要。 |
英文摘要: |
The methods of field experiment,lab analysis and statistical analysis were adopted to study the influence of phosphorus on nutrient content in spring wheat,nutrient absorption,accumulation of dry matter and biological yield of spring wheat.There were two treatments NPK and NK with three replicates for the field experiment and the rate of phosphorus fertilizer was 165 kg/hm2.The results of field experiment showed: the fast phrase of nutrient absorption and accumulation of dry matter were between the phrases of milky and wax maturing.Phosphorus fertilizer could improve nitrogen and phosphorus content in spring wheat, but had less effect on other nutrients in spring wheat.Phosphorus fertilizer could increase accumulation of dry matter of spring wheat,increase yield of spring wheat,and increase content of nitrogen and phosphorus in seed of spring wheat.Therefore,more attention should be paid to using nitrogen fertilizer,phosphorus fertilizer and potassium fertilizer in proper rate. |
