摘 要: | 本文以两年生白术为材料,采用L9(34)正交设计,探究不同施用量的氮、磷、钾混合肥对白术种子产量和质量的影响。结果表明,施肥对白术种子产量及百粒重、发芽率、空瘪率的影响差异均达到一定显著水平,适宜的施肥量组合能有效的提高白术种子产量及降低种子空瘪率。综合得出本次试验的最佳施肥组合为尿素480 kg/hm2、过磷酸钙225 kg/hm2、硫酸钾448 kg/hm2。

Abstract: | Effect of application amounts of NPK-mixed fertilizer on the yield and quality of seeds of two years old A. mac-rocephala by orthogonal design L9(34) were studied. The results showed that the effect of fertilization on the yield, germi-nation, 100-seed weight and the percentage of filled seeds of A. macrocephala were significant. Proper fertilizer composi-tion could increase the yield and decrease the percentage of unfilled seeds of A. macrocephala. Based on comprehensive a-nalysis of the results, urea (480 kg/hm2), calcium superphosphate (225 kg/hm2) and potassium sulfate (448 kg/hm2) were the best fertilizer combination. |
