摘要
为提高钟花樱优质容器苗生产过程中的肥料利用效率,以当年生钟花樱实生苗为试材,采用正交试验设计,分析施用不同混合肥料后钟花樱容器苗的生长指标,对比生长指标和综合指数差异,优化肥料组成,从而筛选出适合当年生钟花樱容器苗的施肥方案。结果表明,施肥能显著影响钟花樱容器苗的存活率、株高、地径和纤弱指数;鸡粪对株高、地径和存活率的影响均达到极显著水平(P<0.01);信噪比因子排秩为鸡粪>花生麸>三元复合肥,最佳组合为A_(3)B_(2)C_(1),即花生麸20 g·株^(-1)、鸡粪10 g·株^(-1)、三元复合肥0 g·株^(-1),该处理的生长综合指数(贴近度)排名第一,综合评分最高。综上所述,在该试验地环境下,钟花樱当年生容器苗的最适施肥方案为花生麸20 g·株^(-1)和鸡粪10 g·株^(-1)混合后分5次施用。
In order to improve the efficiency of fertilization in the production of Cerasus campanulata high-quality container seedlings,the C.campanulata current-year container seedlings were used as experimental materials,the growth indexes of seedlings after applying different fertilizers were analyzed by orthogonal design.By comparing the differences of indexes and the growth comprehensive index,the fertilizer composition was optimized,and the mixed fertilizer suitable for the C.campanulata current-year container seedlings was selected.The results showed that fertilization could effectively effect the survival rate,height,ground diameter and ratio of height to ground diameter of the C.campanulata container seedlings.The effect of fowl dung on the growth of height,ground diameter and survival rate was significant(P<0.01).The rank of signal-to-noise ratio was fowl dung>peanut bran>ternary compound fertilizer.The best combination was A_(3)B_(2)C_(1),which applied 20 g peanut bran,10 g fowl dung and 0 g ternary compound fertilizer per plant.The combination(A_(3)B_(2)C_(1))ranked first and got the highest comprehensive score by the coefficient of variation.In conclusion,in the experimental environment,the optimum fertilization scheme for the C.campanulata current-year container seedlings was 20 g peanut bran per plant mixed with 10 g fowl dung and applied in 5 times.
