以牛角瓜种子为试材,采用正交实验设计L9(34),通过N、P、K 3因素3水平及其不同配比的施肥试验,分析了各元素及其水平对牛角瓜苗高和地径生长的影响,确定了牛角瓜苗期生长的最佳施肥方案。结果表明:105d试验期间不同处理间均呈极显著差异,处理6(N 2.50g/株、P 2.25g/株、K 1.0g/株)苗高指标是最好的,是对照组的3.7倍;处理3(N 1.25g/株、P 2.25g/株、K1.5g/株)的地径指标最好,是对照组的1.95倍,且与其它处理呈极显著差异;对牛角瓜幼苗苗高、地径生长的影响为N>P>K,最佳施肥方案为N 2.50g/株、P 2.25g/株、K 1.5g/株。
The experiment was carried out using orthogonal design L9 (34). The effects of different elements and their levels on the seedling height and Diameter growth, determine the optimum growth planted horn croaker fertilization program. The results showed that there was a significant difference among different treatments during the 105d period. The highest seedling height index of 6 (N 2.50g / plant, P 2.25g / plant, K 1.0g / plant) was the best ; The best diameter index of treatment 3 (N 1.25g / plant, P 2.25g / plant, K 1.5g / plant) was 1.95 times that of the control group, and showed extremely significant difference with other treatments; The effect of high and ground diameter growth was N> P> K. The optimum fertilization plan was N 2.50g / plant, P 2.25g / plant and K 1.5g / plant.
