【摘要】 为探明不同颜色地膜对香料烟种植土壤及生长发育的影响。以香料烟沙姆逊为试验材料，设置无地膜覆盖（CK），黑色（T1）、银色（T2）、透明地膜覆盖（T3）4个处理，研究全生育期不同颜色地膜覆盖对植烟土壤、香料烟发育及烟叶品质相关指标的影响。结果表明，T1～T3土壤温度和含水率高于CK，土壤电导率低于CK,T1土壤碱解氮、速效磷、速效钾、有机质含量显著高于其他处理；不同颜色地膜均可缩短大田生育期，烟株长势、干质量、产量、产值均优于CK。地膜覆盖处理中，T1和T3烟株长势、质量均较好；T1产量、产值显著优于其他处理，分别较CK增加42.21%、49.96%;T1可显著提高沙姆逊烟碱含量；T1主成分分析综合得分最高。综上，采用地膜覆盖措施能够避免生长前期低温冷害，改善土壤环境，促进烟株生长，提高香料烟产、质量和适应性，黑色地膜覆盖效果最佳。更多还原

【Abstract】 To investigate the effects of different color films on soil properties, oriental tobacco growth and leaf quality, four treatments were set up: no plastic film mulching(CK), black(T1), silver(T2) and transparent plastic film mulching(T3). The study examined their impacts throughout the entire growth period. The results showed that the soil temperature and moisture content of T1-T3 were higher than those in CK, while the soil electrical conductivity was lower. The contents of alkali hydrolyzed nitrogen,available phosphorus, available potassium, organic matter in T1 soil were significantly higher than those in other treatments. Different colored plastic film treatments could shorten the field growth period, and the plant growth performance, dry matter accumulation,yield and economic benefit of tobacco were better than CK. In the treatments of plastic film mulching, T1 and T3 showed significantly improved tobacco growth and quality. Notably, T1 treatment exhibited the highest yield and market value, with 42.21%and 49.96% increases respectively compared to CK. T1 significantly increased the Samson nicotine content; and achieved the highest comprehensive score in principal component analysis. In summary, the application of plastic film mulching could avoid tobacco cold damage in the early stage of growth, improve the soil environment, promote the growth of tobacco, and improve the yield, quality and adaptability of oriental tobacco. Among all treatments, black plastic film mulching demonstrated the optimal comprehensive effects.更多还原
