摘要 對常规框栏、常规钝化框栏、喷涂硬质合金框栏进行试验效果分析，并围绕调控各级打叶器的撕叶效率及出叶比例，进而优化叶片结构的思路，设计了一个组合框栏的应用方法。结果表明：组合框栏应用中，二打、三打的撕叶率分别比设计值高2.74和3.23百分点，二打出叶比例比常规框栏提高了2.58百分点，三打、四打的出叶比例分别降低了1.79和1.86百分点。这说明组合框栏主要提升了二打、三打的撕叶率，使二打的出叶比例显著提升，并在一定程度上降低了三打、四打的出叶比例。在叶片结构方面，组合框栏能保持较好的大中片率、碎片率、烟末率、叶含梗率及梗含叶率，长梗率比常规框栏提高了2.71百分点，说明组合框栏能得到较好的叶片结构，特别在长梗率方面具有优化作用。由此可见，组合框栏应用能合理调控各级打叶器的撕叶率和出叶比例，得到良好的叶片结构。

Abstract The experimental results of the conventional fence， the conventional passivation fence and the spraying cemented carbide fence were analyzed， and the thought of optimizing the structure of the blade was put forward based on the regulation of the leaf tearing efficiency and the ratio of the leaf emergence of the leaf thresher at all levels， design a combobox column application method. The results showed that： In the application of the combined frame， the tearing rate of the second-grade threshing and the third-grade threshing was 2.74 and 3.23 percentage points higher than the design value respectively， the ratio of the second-grade threshing was 2.58 percentage points higher than that of the conventional frame， and the ratio of the third-grade threshing and the fourth-grade threshing decreased 1.79 and 1.86 percentage points. The results showed that the combination frame column mainly increased the leaf tearing rate of the second and third order threshing， increased the ratio of the second order threshing， and decreased the ratio of the third order threshing and the fourth order threshing to some extent.In terms of leaf structure， the composite frame column could keep the percentage of large and medium pieces， the percentage of fragment， the percentage of tobacco residue， the percentage of leaf stalk and the percentage of leaf stalk. The percentage of long stalk was 2.71 percentage points higher than that of the conventional frame column， the  results showed that the combined frame column could get better blade structure， especially in the long stem ratio. Therefore， the application of the combined frame could reasonably control the leaf tearing rate and the ratio of leaf emergence， and get a good leaf structure.
