摘要： 为优化新疆喀什地区饲用甜高粱（Sorghum bicolor （L.） Moench）抗倒伏栽培方案，本研究以品种‘惊喜’为材料，采用裂区设计，设置2种株距（Z1：10 cm，Z2：20 cm）与6种行距处理（等行距：30，40，50 cm，宽窄行：20+40，30+50，40+60 cm）共构成12种株行配置。测定两茬农艺性状、茎秆化学组成、茎秆机械强度及倒伏率。结果表明，株行配置显著影响甜高粱抗倒伏相关性状。在两茬处理中，等行距（50 cm）和宽窄行（40+60 cm）处理田间倒伏率较低；其中等行距50 cm（H5）处理机械强度最高、纤维组分积累最优。相关性分析表明，第一茬抗倒伏主要依赖茎粗、壁厚与机械强度协同增强，第二茬则依靠纤维组分（ADF、NDF、木质素）积累。综合两茬评价得出：等行距H5配置，无论是搭配Z1还是Z2株距，均可显著提升抗倒伏性能，是该试验条件下最优模式。本研究结果为干旱区饲用甜高粱抗倒栽培提供了具体的技术方案与理论依据。

Abstract: To optimize the lodging-resistant cultivation scheme for forage sweet sorghum （Sorghum bicolor （L.） Moench cv. ‘Jingxi’） in Kashi， Xinjiang， a split-plot design was used with two plant spacings （Z1： 10 cm， Z2： 20 cm） and six row spacing configurations （equal row spacing： 30， 40， 50 cm； wide-narrow row spacing： 20+40， 30+50， 40+60 cm）， resulting in 12 plant-row configuration treatments. Agronomic traits， stem chemical composition， stem mechanical strength， and field lodging rate were measured over two harvests. The results showed that plant–row configuration significantly affected lodging-related traits. Across both harvest s， equal row spacing of 50 cm and wide-narrow row spacing of 40+60 cm exhibited lower lodging rates. Among these， the equal row spacing of 50 cm （H5） treatment produced the highest stem mechanical strength and the best accumulation of fiber components. Correlation analysis revealed fundamentally different lodging resistance mechanisms between the two stubbles： lodging resistance in the first stubble depended on the synergistic enhancement of stem diameter， wall thickness， and mechanical strength， whereas that in the second stubble relied on the accumulation of stem fiber components （acid detergent fiber， neutral detergent fiber， lignin） to maintain strength. Comprehensive evaluation of both stubbles indicated that the H5 configuration （equal row spacing of 50 cm）， whether combined with Z1 or Z2 plant spacing， significantly improved the overall lodging resistance of ‘Jingxi’ and was the optimal pattern under the experimental conditions. These findings provide a specific technical scheme and theoretical basis for lodging-resistant cultivation of forage sweet sorghum in arid regions.
