从区组内林木生长差异的趋势,分析讨论了提高南方丘陵台地林木施肥试验局部控制效率以及确定合理重复数的一般原则;对现有林施肥和某些区组效率较低的试验,如何更客观地反映试验处理的真实效应或进一步改善试验精度等亦进行了简要的讨论。
From the trends of differences in the growth of trees in the blocks, the general principles for improving the local control efficiency of forest fertilization experiments in southern hilly terraces and determining the reasonable number of repetitions were analyzed and discussed. Objectively reflect the actual effect of the test or to further improve the accuracy of the test also conducted a brief discussion.
