Abstract: To explore the effects of different combinations of shaping pruning and fertilizer on the growth of spring shoots of C. oleifera in order to provide evidence for the cultivation of high yield in closed C. oleifera stands. Using the canopy closed C. oleifera as the research object, L₉ (3⁴) orthogonal experimental design was used to set the combination of variety type, fertilizer type and pruning method, and determine the spring shoot index, leaf index and flower bud index in the next year. The test results show that: (1) The results of ANOVA show that each factor has a very significant impact on the measurement index. The variety type had significant effects on the number of flower buds in primary lateral tip, the number of leaves in top tip and secondary lateral tip, and the physiological indexes of leaves. Fertilizer type had significant effects on the length of top tip, the length of primary branch, the number of flower buds and the physiological indexes of leaves. Pruning methods had significant effects on tip length, leaf SPAD value, leaf surface humidity and leaf surface temperature. (2) Multiple comparative analysis is possible, and each treatment has a significant impact on the measurement index. Treatment 4: The spring shoots of C. oleifera grew well, and the number of leaves was the largest; Treatment 2 had the highest number of C. oleifera flower buds; Treatment 3: The best physiological indexes of C. oleifera leaves. Considering the comprehensive yield factors, treatment 2 was the best combination method, that is, on the "Xianglin 210" variety, it was pruned into a natural happy type, and at the same time, organic fertilizer (2 kg) + compound fertilizer (1 kg) was added.
