探讨整枝与产量形成的关系，为番茄整枝增产提供理论依据。试验设三种整枝方式即单干整枝、连续两段摘心整枝及老株再生整枝，结果表明：单干整枝、连续两段摘心整枝同化产物的积累一生中呈“Ｓ”型曲线变化；老株再生整枝于株龄１９８天以前符合Ｓ曲线，株龄１９８天以后又有一个积累的高峰期称再生期。整枝改变了同化产物积累各阶段的长度，提高了同化产物对果实的分配率。与单干整枝相比，连续两段摘心整枝８５％以上的产量集中在结果中后期，老株再生整枝产量分布于结果前期和结果末期。
Discuss the relationship between the pruning and the yield formation, and provide theoretical basis for the pruning of tomato. Three types of pruning methods, namely single pruning, continuous two-prong pruning and old pruning, were set up in the experiment. The results showed that the single-pruning pruning resulted in the change of “S” 198 days ago in line with the S-curve, 198 days later, there is a cumulative peak period known as the regeneration period. Pruning changed the length of the assimilation product accumulation stage, increased the assimilation product on the fruit distribution rate. Compared with the single-branch pruning, more than 85% of the total yield of the two-part topping pruning was concentrated in the middle and late stages of the result. The yield of the whole plant regeneration pruning was distributed in the early stage of the result and the last stage of the result.
