调光地膜覆盖栽培对地温及烤烟生产的影响

摘要

In order to further increase tobacco yield, its value, and income of planters in Guizhou, field experiments were conducted to compare the effects between light adjusting film and ordinary plastic film. The results showed that light adjusting film had better effect (0.3-2.0 'C) than ordinary film in increasing ground temperature, and light adjusting film increased the number of tobacco effective leaves, shortened field growth period, promoted tobacco mature, increased yield and higher grade leaves, and output. Therefore, light adjusting film has high potential in flue-cured tobacco production.%为进一步提高贵州烟叶单产,增加种烟效益,开展了烤烟调光地膜和普通地膜覆盖栽培比较研究.结果表明,调光膜比普通膜增温0.3 ～ 2.0℃,效果较明显；调光膜覆盖栽培可增加烤烟有效叶片数,缩短大田生育期,促使烟叶成熟期提前,增加产量、上中等烟比例和产值.因此,调光膜覆盖栽培烤烟是一项值得推广的技术.
