摘要
为了提高切花月季卡罗拉的产量和质量,以贵阳市2年生切花月季卡罗拉(Carola)为材料,采用5因素4水平正交试验L16(54)对其进行N、P、K最佳施肥配比根际固体埋施试验研究。结果表明:根际追施N肥对切花月季卡罗拉发枝时间、发枝数、花枝长度影响较大,追施P肥对其花蕾直径影响较大,追施K肥对其枝条粗度影响较大。N∶P∶K=8∶30∶0和8∶45∶5的配比即11号试验组合N3P3K1(根外追施尿素8g/株、过磷酸钙30g/株、不追施硫酸钾)和12号试验组合N3P4K2(根外追施尿素8g/株、过磷酸钙45g/株、硫酸钾5g/株)能有效提高切花月季卡罗拉的产量和质量,适宜在生产中推广应用。
. The grafted seedlings of Carola (a biennial rose variety) were applied with different N, P and K combinations by using L16 (5^4) design to probe the optimum N, P and K combinations for improving its yield and quality. The results showed that N fertilizer had the great effect on its branching time and number, and branch length. P fertilizer had the significant effect on its bud diameter. K fertilizer had the significant effect on its branch diameter. The optimum N, P and K ratio was 8 : 30 :0 and 8 : 45:5 respectively, which could effectively improve yield and quality of Carola and be used in production of Carola cut flower.
