小麦不同品种氮钾效率差异的研究

The Study on the Variations of Nitrogen and Potassium Efficiencies With Different Wheat Varieties

本试验选用西南农业大学农业系小麦育种教研室提供的、在重庆地区有推广价值的８ 个小麦品种，通过土培研究了它们的氮、钾效率的差异．结果表明：在低、高肥条件下，品种间氮 的吸收效率差异不显著；在中肥条件下，差异显著各施肥条件下，品种间氮的利用效率、钾的吸 收和利用效率差异均达极显著．

Soil experiments were carried out with 8 wheat varieties supplied by Teaching and research section of wheat breeding in Agronomy Department in Southwest Agricultural University and planted widily in Chongqing. The results are following as: No significant variations were observed in N absorption efficiency among wheat varieties in low and high fertilization treatments, the difference among wheat varieties is in middle. N utilization differentiated obviously in 8 wheat varieties in variable fertilizer treatments. The K absorption and utilization efficiencies were obtained differently in wheat varieties in low.middle and high fertilization treatments. By the experiment conclusions, we would know XiFu 10 was worth of planting in modern Agriculture; XiFu 3 was able to well under the conditions of different fertilization
